    How did we pick the best solar companies of 2024?

    We compared popular solar companies on customer satisfaction ratings, warranties, payment options and other factors. Sunlux has great reviews but somewhat limited availability. Project Solar, Freedom Solar Power and Blue Raven Solar are worth considering for professional installation — compare quotes to find the best deal in your area. Start with ShopSolar if you already know what you need for a DIY or off-grid project.

    Companies may be Authorized Partners that compensate us, but this does not affect our recommendations or influence evaluations. Our publishing policy ensures that the journalistic content and user reviews on ConsumerAffairs remain independent of commercial influences.

    Sunlux stands out for its competitive pricing, good customer service and quality solar panels. Its 24/7 monitoring app lets you easily track your system’s performance, and tech support is on standby if anything goes wrong. We also like that Sunlux can take care of any necessary roof repairs or replacements before installing your system (for an additional charge).

    We’ve heard from over 570 verified customers since 2017. Compared with industry averages, Sunlux reviewers are more likely to give positive feedback on customer service. They also have good things to say about the app and online experience.

    I'm pleased with knowing that Sunlux not only gave me a good deal, but also good equipment.”
    — Adolfo, a Sunlux customer in California

    Pros

    • Great equipment options
    • 24/7 monitoring app
    • Helpful sales reps
    • Lifetime customer support
    • Flexible financing options

    Cons

    • Limited availability
    • Not always the cheapest option
    • No in-house financing
    • “I interviewed several people and Sunlux had the best price and their solar energy system looked like a good product. … They have people behind them who know what they're doing. They did a nice job and worked well with the power company.” — James in California
    • “I have the best-looking panels on the block. I like the low profile, the black panels. The installers put a skirt on the front. They put some rodent prevention and showed me how to work the system. ... So, I'm pleased with knowing that Sunlux not only gave me a good deal, but also good equipment.” — Adolfo in California
    • “My experience with the SunLux reps was fantastic. They were knowledgeable and professional. ... The process with Sunlux was quick, easy and painless. We had a flat roof with a foam top, which was a problem for the other company. But Sunlux was able to do it. It has rained, but there had been no leaks.” — Robert in California
    • “Their presentation was much better than some of the other folks we talked to. They had a better sense of what they were talking about and were able to portray that to me, who did not know anything about solar. The installation went really well, and really, really quickly.” — Jeremy in Texas

    Including materials and labor, John in California paid $20,000 for his system. How much your system costs depends on how much energy your house uses, the condition of your roof and other factors.

    Many customers finance, like Christian in California. “Instead of paying $100 or $200 for the electric bill, if I use the same amount of energy or less, I will end up paying just the financing, which is $150,” Christian told us. “But only for six years, and then after that, the panels will be mine and I don't have to pay anymore.”

    Since going solar with Sunlux, Ana in California and Michael in California both only pay their utilities about $20 per month, mostly minimum service fees.

    If direct, in-person communication is important to you, consider working with a small local operation. Keone in California, who still recommends Sunlux overall, told us, “The only thing is I'm old school so I don't always like email stuff but everybody goes through email. I would rather they call me. But for the most part, I'm fine with it.”

    Another thing to consider is availability: Sunlux currently only operates in Southern California and Central Texas.

    Sunlux installs Panasonic and Qcells solar panels. Tesla Powerwall, Enphase AC Battery and LG Chem RESU batteries are available. Systems incorporate SolarEdge inverters and Enphase microinverters.

    • Energy services: Sunlux specializes in solar panel installations with storage batteries. Roofing, EV charging and smart home solutions are also available.
    • Payment options: Sunlux offers unsecured loans through third-party solar loan partners. You can also lease a system with no upfront costs. Lease agreements last 25 years.
    • Warranties and guarantees: Sunlux has two tiers of warranty options. The standard warranty covers installation, parts and maintenance for 25 years. With Platinum Protection, Sunlux also covers labor for repairs and guarantees how much energy your system generates for 25 years. It also covers equipment degradation plus parts and labor costs for maintaining your system during this time.

    Project Solar reps don’t work on commission. Instead, they focus on a simple, streamlined customer experience. This no-sales-gimmicks approach appeals to more budget-conscious solar clients who want professional or DIY installation.

    We also appreciate the price transparency. The website provides clear information on pricing models and potential savings. As of publishing, full-service installations start at $1.61 per watt. DIY projects are cheaper, starting at $1.26 per watt. Power Purchase Agreements range from 10 cents to 15 cents per kilowatt-hour (kWh). Anything over 13 kilowatts is a flat rate.

    The main reason I went with them was the price. They're not paying overhead or for salespeople.”
    — Stan, a Project Solar customer in California

    Pros

    • Transparent pricing
    • Streamlined installations
    • Great for cost savings
    • Roof-leak warranty

    Cons

    • Less equipment options
    • Subcontracted installers
    • No in-house financing
    • “The price of the product considering the brand name, the kind of materials that they use for their products, and the quality was considerably better value than other options available. It's really good value for really good components. Also, I liked their no-salesperson sign-up process. It was easy and simple.” — Franklin in Texas
    • “Project Solar is practical. They're well-priced, and they work with their customers … It performed like they said or better than what they claimed that it would. We are so satisfied with this thing.” — Janet in Wyoming
    • “The system gives the same features that other big companies give, and it's cost-efficient. For the same amount of kilowatts, my friend installed a higher rate, whereas I am done with $13,000 and he paid $24,000. We both are producing the same amount of energy now. If you know how to install things, it's even cheaper.” — Praveen in Florida
    • “They did it very fast and they really know what they were doing. After that, they installed things properly. Also, I have compared their price with other companies with similar configuration and going with Project Solar saved me around $5,000 to $10,000.” — Lenin in Texas

    Bill in Utah considered more than six solar companies. Each quoted him nearly $30,000, but Project Solar was less than half of that. “I jumped on it,” Bill told us. Now, he pays less than $15 per month for power (that’s his minimum utility subscription fee).

    Similarly, Joe in Florida spent $14,000 on his Project Solar installation, and Gary in Colorado only has to pay a $10 monthly fee to his utility since his project was complete.

    “I paid $20,000 more or less for everything,” Dion in Nevada told us. “That's including the cost of my own install and the electrician that came out that wasn't part of Project Solar. Then I got a six-plus-thousand-dollar refund from taxes. The entire system, over 10-kilowatt, is $14,000 which is great.”

    The focus on streamlining might mean fewer customization options or solutions for complex roof situations. For instance, John in Arizona said no one mentioned getting critter guards, which is fencing that keeps animals from nesting in solar panels. He had to have contractors come back and add them later.

    Another customer, Stan in California, mentioned installation delays and inconsistent communication. His initial system design didn’t account for the electricity needed for his pool pump, and there was a delay in relaying that information to the installers. “But with everything else, the job was good,” Stan told us. The main reason he went with Project Solar was the price.

    Project Solar systems incorporate equipment from reputable brands like Qcells, Canadian Solar, Jinko and Enphase. As part of the full-service installation, it offers Enphase IQ 5P or Tesla Powerwall batteries. DIY projects only have the Enphase IQ 5P option. It currently operates in multiple states across the U.S.

    • Energy services: Project Solar specializes in system design and equipment procurement for professional and DIY solar panel installations.
    • Payment options: Project Solar partners with a few lenders to offer two main financing options for professional solar installations:
      • Option A is cheaper overall: It has a higher interest rate, but any extra payments go directly towards reducing the principal amount. If you pay off the loan early, this can save you from paying excess interest.
      • Option B has a lower monthly payment: It has a consistent payment over a longer term. The interest rate is lower, but there may be prepayment penalties.
    • Warranties and guarantees: Project Solar provides two main warranties: a 25-year manufacturer’s warranty and a 10-year workmanship warranty. There’s an 84% production level guarantee for 25 years, which provides reimbursements if production levels are unmet.

    Selected for having one of the highest satisfaction rates for Best Customer Service and Best for Installation

    We’ve heard from over 200 verified Freedom Solar Power customers. Over a recent two-year period, 85% were happy with the customer service, 92% were satisfied with the installation and setup and 94% were pleased with the price. People also find the app helpful in tracking energy production post-installation.

    We like that it has an in-house staff of NABCEP-certified installers and licensed electricians. It doesn’t subcontract work to local companies like some big national solar energy providers, so you can expect more personalized customer service throughout the installation process.

    They're saving us money, and I'm satisfied with Freedom.”
    — Michael, A Freedom Solar customer in Ohio

    Pros

    • Excellent customer service
    • 24/7 performance monitoring
    • Transferable warranty
    • In-house, NABCEP-certified installation crews

    Cons

    • Somewhat limited availability
    • No in-house financing
    • “Since getting the solar panels installed, we've gotten cheaper bills. They're saving us money, and I'm satisfied with Freedom. If you're interested in solar, they're a good company to get the job accomplished fast.” — Michael in Ohio
    • “They handled all of the stuff with the enrollment process. We just filled out whatever the forms were, and it all worked out perfectly. They did the installation really quick. It all went pretty well. Our electric bill has been about $3. It's been great. It worked out exactly what we expected. It was well-managed. The customer service was great. They checked on us. I couldn't ask for anything more.” — Lynda in Texas
    • “When I first reached out to Freedom Solar, the rep was very nice, explanatory, and respectful and he had answers to any question I had… Since having the system, I'm glad with the dollar amount that comes in my bill. In the summer, I would get $400 and $500 bills but now, I'm getting $30. The most I've gotten is a $50 bill. It's a big difference, and I'm 100% satisfied with going solar.” — Virginia in Texas

    Freedom Solar is not the cheapest, according to Penny in Texas. Her quote was about $4,000 more than another company she considered. “But in addition to the fact that they are larger and have been around longer, the level of service was outstanding,” she said.

    Joel in Texas said his system cost $32,000. On the high end, Russell in Texas spent over $120,000 on a system, including the Tesla battery.

    The return on your investment depends on where you live and how much energy you use. Anecdotally, John in Texas said his electric bill went from over $100 to about $5; Michelle in Florida said their monthly bill went from $150 to $35.95.

    “I'm saving anywhere from $150 to $300 a month, depending on the month,” Lynn in Texas told us.

    The installation process is generally smooth and efficient, though a few customers seemed annoyed by supply chain delays (a common theme in many solar company reviews).

    “They also didn't mention that twice a year, you have to pay to have the panels washed and it's a $600 to $800 expense,” Julie in Fort Worth said. “That was a total surprise to me and they didn't tell me that at all until I was closing up.”

    Freedom Solar Power installs American-designed solar panels built to last at least 25 years. The company specializes in rooftop solar panels and ground-mounted systems. Battery options include SunVault backup power systems and Tesla Powerwalls. It currently operates in Texas, Florida, Colorado, Virginia, North Carolina and South Carolina.

    • Energy services: Besides solar panel installations, Freedom Solar Power offers Deinstallation and reinstallation for roof repairs, energy monitoring, repairs, maintenance and upgrade services.
    • Payment options: Freedom Solar systems are available for cash purchase. There are also financing options with low interest rates, no money down and 12 months of same-as-cash, which end up costing around $1 per day. It does not currently offer a leasing plan.
    • Warranties: Freedom Solar Power has a 25-year lifetime warranty on equipment and installations. If problems arise, the company replaces equipment on behalf of the manufacturer and covers 100% of repair or replacement costs. System performance is guaranteed between 84% and 92% of original production for 25 years.

    Blue Raven Solar has affordable financing programs to minimize out-of-pocket costs. We also like that reps take a technology-focused approach tailored to different climates across the country. It has a good mobile app that lets you monitor your system’s energy production and usage from anywhere.

    They gave us top rated materials, good price, honest timeline that was fair and quality installation.”
    — Terry, a Blue Raven customer in Illinois

    Pros

    • Sleek, durable systems
    • Referral cash bonus
    • In-house financing
    • Zero-down loans

    Cons

    • Occasional installation delays
    • Some miscommunication
    • “Blue Raven has been 5 star all the way since we had our first meet! They are punctual, informative, patient, and experienced! I am so happy we were referred to them and would refer them to any and everybody who is even thinking about adding solar panels to improve their home. Excellent service and knowledge!” — Jim in Colorado
    • “Blue Raven did a great job laying out the cost/benefit analysis and return on investment. And they have made it really easy to get going (paperwork, etc.) and installation went great. Everybody has been really friendly and nice to work with. And, there’s been very limited work on my end throughout. Certainly recommend!” — Anthony in Michigan
    • “When we first had a representative at our door about the solar system, we knew it would be a good purchase. Everything was explained very professionally, and nothing felt like it was being forced towards purchase. When we decided to go for it, everything from the contract to the installation was very fast and on time! Everybody did an awesome job!” — Dong Min in Michigan
    • “I am very happy with Blue Raven team and Lorenzo especially. Very seamless experience, amazing sales person and very professional installation crew. Very happy with the experience so far. The whole process took less than 45 days from start to finish and I was kept informed at every step. They provided the best design and cost recommendations based on my needs and the best in class panels and inverter.” — Kaushik in Illinois

    Jason in Washington put it this way: “The cost of having solar is expensive, however, paying a monthly electricity bill is also expensive. In the end, they cancel each other out, you pay for the installation of solar panels, but you pay less on your electricity bill.” On the high end, James in North Carolina told us their Blue Raven Solar system cost $100,000.

    “Even running the air conditioning my bill is $0,” Paul in Michigan told us, “so they delivered on everything they promised.”

    Not everyone is as satisfied, unfortunately. Lyubov in Washington spent $51,000 going solar with Blue Raven. Depending on the time of year, they save between $35 and $113 monthly. Lyubov estimates it will take 100 years or more to break even.

    Kevin in Minnesota said his only issue was that there wasn’t a clear timeline to get the system activated after installation, which took several months. “Also, there was no communication on the ‘consumption meter,’ which tells you on the app how much power your household is consuming versus how much the solar panels are generating,” Kevin told us. “Other than that, it’s been a great experience.”

    Blue Raven Solar offers homeowners a simple and affordable way to go solar. The company is currently available in 21 states.

    • Energy services: Solar advisors use proprietary software to design custom systems that maximize annual energy output, and its installers employ low-profile panel mounting and sleek cabling for visual appeal.
    • Payment options: Eligible customers can pay $0 upfront, get 18 months of free solar power and make fixed monthly payments after that. You own the system and are responsible for maintenance. It also offers a fixed monthly payment option — no prepayment penalty, and the plan is transferable to a new homeowner if you ever sell your house.
    • Warranties: All systems have a 25-year panel and a two-year production guarantee. Storage battery warranties vary between 10 and 15 years. Workmanship is guaranteed for 10 years.

    ShopSolar is an awesome place to buy solar equipment for do-it-yourself projects. We like that the online retailer has a nice selection of equipment, fast deliveries and good communication. You can find new and used solar panels, solar storage batteries, inverters, charge controllers, cabling and hardware, mounts and racks — everything needed for an off-grid or hybrid setup. It also sells different monitoring systems that connect through Bluetooth or manufacturer apps.

    We were looking for an off-grid solar kit deal and started looking around, and ShopSolarKits was the most reasonably priced.”
    — Kevin, a ShopSolar customer in Missouri

    Pros

    • Wide selection for off-grid and DIY projects
    • Great for RVs and outbuildings
    • Price-match guarantee
    • 30-day return policy
    • Lifetime customer support

    Cons

    • Shipping and delivery restrictions or delays
    • Occasional issues with defective or damaged products
    • “We were looking for an off-grid solar kit deal and started looking around, and ShopSolarKits was the most reasonably priced… I put up everything myself. It was super easy.” — Kevin in Missouri
    • “Finding what I needed was easy. I use my Titan Solar Generator every day. I have it in an RV, and I run the air conditioner for six to eight hours. Also, customer support was great. We had trouble with the chargers, and we've had two that went bad. They covered them all. Also, one of the charges that were in the cigarette lighter went bad. They covered that as well. They were very attentive to that.” — James in Arizona
    • ”My experience with them has been fantastic. I'm very happy with them. The process was very easy. We told them what we were looking for, what we wanted the unit to do, and they did all the calculations and told us exactly what we needed, and that's what we went with…” — Gerald in Florida
    • “This company is not only helpful but they actually care about their customers. I had a situation that they could have easily Just wrote me off and instead worked side by side with me to fix the issue. I have spent over $11k with this company and I will be spending more in the future.” — Tyler in Texas

    Patrick in Missouri spent $6,000 on a kit in 2023. As of publishing, ShopSolar’s best-selling complete solar power system kit costs $2,889. On the high end, its 75.8kW Solar Power System costs $180,989. Individual solar panels cost anywhere from around $45 to almost $10,000.

    “I've had the kit installed for about eight months, and I don't have a bill,” Jordan in Oregon told us. “It was cheaper for me by about $20,000 to go with ShopSolar and I can expand the system as I need to.” Carlos in Florida told us he’s saving $200 each month with his kit.

    ShopSolar does not provide professional solar panel installation services. So, it’s best to know a little about solar panels and electrical work. You might get frustrated with the process or install something incorrectly otherwise.

    For instance, T. in Colorado said, “Installing the panels was initially not so easy ‘cause I didn't have experience, but having conversations with a couple of folks at ShopSolarKits, I was able to do it myself and it was easy. I bought a big battery, and I would have bought some higher wattage panels had I had a little more information. Other than that, their follow-up service was exceptional.”

    Complete guide to going solar

    We’ve heard from over 100,000 verified solar customers since 2018. A couple of things we know for sure: People like powering their homes with a reliable source of cheap, clean energy. They don’t like getting into solar contracts that don’t meet their expectations. Here’s what to consider when selecting a solar company, how to think about solar costs and what to expect during and after the installation.

    Key insights

    Getting proposals from at least three or four solar companies lets you evaluate pricing, financing terms, equipment options and overall company fit.

    Jump to insight

    Cost is important, but so is equipment quality, customer service, transparent pricing and robust warranties. The cheapest option might not be the best long-term solution.

    National installers have a broader reach, but local and regional companies often have better knowledge of the regulations and incentives in your area.

    How much do solar panels cost?

    In 2024, the average home solar system costs $22,712 before the 30% federal solar tax credit.

    On average, homeowners with solar panels avoid $62,219 in total utility costs over 25 years.

    A typical 8-kilowatt (kW) solar panel system costs $22,712 before any financial incentives. However, with solar leases and financing plans, installations can cost almost nothing upfront.

    Think about how much it costs to go solar the way you shop for a car. Just like car manufacturers use miles per gallon (MPG) to show how fuel-efficient their vehicles are, solar panels are measured by their cost per watt to show how much energy you get for each dollar you spend.

    Overall, solar photovoltaic (PV) panel prices are steadily going down year over year. A scenario where you would pay a higher total cost but get a cheaper cost per watt typically involves purchasing solar panels in bulk (or investing in a large commercial system).

    How to pay for solar panels

    You can pay for your system upfront, but most people finance solar panels. A solar loan works like any other type of loan — there's an application and approval process, and you pay it back over time (with interest).

    Alternatively, solar leases and power purchase agreements are a good option if you have limited savings and don’t want to take on debt. A potential downside to leasing is that you won’t be eligible for the federal solar tax credit.

    In some states, Property Assessed Clean Energy (PACE) programs let you finance through payments made to your property taxes. This can significantly increase tax bills and lead to foreclosure if unpaid. It also puts a lien on your house, which takes precedence over your mortgage and can complicate selling your home.

    » SOLAR PANELS: Buy vs. lease

    Taking advantage of the federal solar tax credit

    The 30% federal solar investment tax credit (ITC) is the best financial incentive for most homeowners buying solar panels. The solar ITC represents a dollar-for-dollar reduction in avoided tax payments worth 30% of your system cost, including labor and permit fees.

    The ITC is a credit, meaning it directly decreases the amount of taxes you owe. This is different from a deduction, which lowers your taxable income.

    For example, if you spend $10,000 installing a solar panel system, the ITC is worth $3,000. If you owe $5,000 in taxes, the $3,000 credit reduces what you owe to $2,000. Any unused portion rolls over to the next tax year. However, getting a refund check is possible if the ITC credit reduces your taxes to the point where you overpaid during the year.

    What to consider before going solar

    Not every household benefits from solar panels in the same way. For best results, you need plenty of sunlight and a strong roof that faces the right direction. The other big factor is your roof. Here's what else to consider before you commit.

    Is your house a good candidate for solar panels?

    • What is the condition of my roof? Solar panels can last for 25 years or more, so your roof needs to last at least that long. It's a good idea to replace your roof before installing solar panels. Otherwise, you'll have to spend thousands to remove the panels, fix your roof and reinstall them again in the future. Devin in California said it cost $5,000 to remove the panels and reinstall them again when they needed to replace their roof.
    • How much energy does my household use? Look over your past electricity bills to understand your monthly energy consumption patterns. If you finance solar panels (many homeowners do), it might not be worth it if the loan payments for your solar panels are more expensive than your existing electricity bill.
    • What is my roof's angle, pitch and size? Generally, a roof pitch of 25 to 45 degrees is best in the United States. Roofs that face south, southeast or southwest are typically the best angle for solar panels.
    • How much roof space do I have? The average dimensions of a solar panel are roughly 5.5 feet by 3.25 feet. Ideally, your roof is big enough to fit the number of panels required to meet your energy needs. Some homeowners install smaller systems that produce around 80% of the power they need.
    • How much sunlight does my roof get? Solar panels need regular exposure to sunlight to produce the most energy possible. If there's a lot of shade around your house — lots of tall trees or buildings, for instance — your solar panels won't be as efficient. Solar panels still work on cloudy days, but the electricity generation drops to about 10% to 25% compared to sunny weather. Direct sunlight definitely boosts energy output.

    What are the best states for going solar?

    See how your state compares with others on residential electricity prices, solar installation costs, solar potential and solar-friendly policies.

    How to choose a solar company

    Here's how to narrow down your options and find a reputable solar energy company that can provide ongoing service at a competitive price.

    1. Do your research

    It's worth considering all your local options. Read lots of solar company reviews and check for any complaints filed against the company. Look out for pushy sales reps when you start these conversations. Unhappy solar customers often tell us about sales reps making false promises, particularly around rebates, credits and savings.

    2. Compare a few quotes

    "The price of a system will depend on your electricity usage; there's not a fixed price but more of a range," Neil Gallagher, who owns a company in Tampa, Florida, told us. "Since COVID, the price of materials has gone up due to supply chain issues, mostly foreign panels. The cost of labor has also increased."

    3. Check licenses and certifications

    Before you hire anyone, request their license number and any credentials they claim to have. You should also check that the company has liability insurance, especially since technicians will be on your roof.

    For credentials, reputable solar companies often have affiliations with organizations like the North American Board of Certified Energy Practitioners (NABCEP) or are certified by the Solar Rating and Certification Corporation (SRCC).

    4. Ask about solar panel efficiency

    When comparing solar panels, look for reliability, efficiency and durability. Higher-efficiency solar panels are more expensive but generate more electricity and require less space. Depending on where you live, the panels might need to be tough enough to withstand harsh weather conditions like hail, wind and snow. Quality solar panels are designed to last 25 to 30 years, but the efficiency of solar panels decreases a bit each year.

    5. Pay attention to the warranty

    The best local solar energy installers always offer warranties and service guarantees. They're also readily available for maintenance, system checks or addressing any concerns you might have after your solar system is installed.

    Panels usually come with a manufacturer's warranty that covers the panel's performance and materials. A good warranty should cover at least 25 years for panels. In some states, you need at least that to qualify for certain renewable energy incentives. Solar inverters are also a common source of maintenance issues, so check your warranty for the inverter you choose. A typical warranty for a solar inverter lasts between 10 and 25 years.

    How do solar installations work?

    Understanding the installation process is important to know what you should expect.

    1. Initial consultation: When you start contacting solar installers for quotes, some may show you satellite images of your home at different times of the day. They use these pictures to demonstrate which sides of your home get the most sunlight.
    2. Site assessment: The installer often conducts a physical or remote (using satellite imagery) assessment of your property. They evaluate your roof's orientation, size, shading and condition. These assessments provide an overview of your property's overall solar potential.
    3. System design: The installer then designs a solar system for your property and provides a detailed proposal based on the site assessment and your energy needs. This proposal should include the system size (in kilowatts), estimated energy production, cost, potential savings and return on investment.
    4. Panel installation: After you secure your permits, your solar company begins the installation process. Local installers often have in-depth knowledge of local building codes and practices that help ensure smooth installation. This process typically takes a few days but can vary based on the system's size and complexity.
    5. Final inspection: Once the solar system is installed, it needs to be inspected by local authorities and the utility company (if grid-tied) to ensure it meets all regulations. After inspections, the system can be commissioned, and you can start generating solar power.

    Is going solar worth it?

    Despite the high upfront costs, “the energy savings can offset the initial investment with a great (return on investment),” according to Warren Matthews, co-founder and head editor at Helius Hub. "Based on my experience, people often overlook, when buying/installing solar panels, the importance of proper installation and maintenance of the panels," Matthews said.

    Solar panels save most people money over time. On average, solar panels pay for themselves in savings within about 9.5 years. Over 25 years, the average homeowner with solar panels avoids $62,202 in total utility costs.

    FAQ

    How do solar panels work?

    Solar photovoltaic (PV) panels work by harnessing the power of the sun and converting it into usable electricity. The most common types of residential solar PV panels — monocrystalline and polycrystalline — are made of silicon cells, which easily absorb photons from the sun.

    If your solar panel system is connected to the grid, any excess energy your system generates during the day can be fed into the grid and credited to your account through net metering. At night, your system can draw energy from the grid to power devices and appliances in your home.

    Solar panels still work on cloudy days, but the electricity generation drops to about 10% to 25% compared to sunny weather. Direct sunlight definitely boosts energy output.

    How many solar panels do I need to power my house?

    The average American home ends up needing 15 to 30 panels to fully power their household. How many solar panels you need depends on your energy usage, roof and solar panels' efficiency. To figure out your energy usage, check your utility bill for "kWh used." To get your monthly average, look at bills for the past year, add up the stated kWh used and divide by 12.

    In general, the output of one residential solar panel is anywhere from 100 watts to 500 watts, depending on the capacity of the equipment and its operating conditions. Most panels on homes are rated to output between 250 watts and 450 watts, meaning they produce 250 to 450 watt-hours of electricity for each hour they are exposed to direct sunlight.

    What are the different types of solar equipment?

    It's not just about picking the best solar panels. A solar array is made up of many different components. Think about how your whole system will work together.

    • Solar batteries store that sunny day for a rainy one. If you want to store the energy produced by your solar panels for use later, you need to install solar batteries. This is especially useful if you live in an area with frequent power outages or if you want to use solar energy when the sun is not shining. If you get a battery, you'll also need a charge controller.
    • Mounting and tracking systems maximize sun exposure. This attaches the solar panels to your roof or another location on your property. The mounting system needs to be sturdy and weather-resistant.
    • Inverters turn sunlight into usable energy. The solar inverter converts the direct current (DC) electricity produced by the solar panels into alternating current (AC) electricity that can be used to power your home or business.
    • Monitoring lets you keep track of your system through an app. Monitoring apps provide real-time data on the performance of your solar panels. You get an alert if there's a drop in performance. Some advanced monitoring systems let your solar installation company access performance data remotely, which facilitates quick repairs.
    How often do solar panels need to be cleaned?

    Hosing down solar panels once or twice a year should keep performance high. Otherwise, dirt, debris and other substances accumulate on panels over time, reducing their effectiveness. You can clean your panels yourself or hire a professional to keep up with solar maintenance. Hiring someone to clean your panels typically costs around $150 to $300 per visit. It's important to only clean panels yourself if you can do so safely, and to make sure not to damage the panels by scrubbing them.

    How much can I save with solar panels each year?

    The amount you can save on your electrical costs with solar panels each year depends on how much you normally spend on electricity. You could see net savings anywhere from $10,000 to over $40,000 over the course of 25 years.

    What solar options are available for small businesses?

    Businesses, local governments and nonprofits of all sizes can benefit from commercial solar panel installation. Solar carports, ground-mounted systems and solar thermal energy systems are also options. The biggest difference between commercial and residential solar panels comes down to scale, financing options and tax incentives.

    Methodology

    ConsumerAffairs used a data-driven approach, guided by its expert editors, to select the top solar companies. This process is regularly updated to reflect new customer reviews, company data and industry trends.

    To identify the top five picks for different buyer needs, including the best overall solar company, we applied a weighted scoring system that considered verified customer review data and available information on features including payment options, equipment selection, warranties and guarantees.

    Selection process

    We conducted a sentence-by-sentence sentiment analysis of thousands of reviews on our site from Oct. 1, 2021, through Sept. 30, 2024, to identify the aspects that people care about most in solar companies. We then decoded the reviews and star ratings to calculate the percentage of reviewers who are “happy” or “satisfied” with each aspect for each company, which we refer to as the “satisfaction rating” for that aspect. For solar companies, these aspects included installation, customer service and price.

    For each satisfaction aspect or feature, a company received a score from 0 to 10. The company with the best satisfaction rating or strongest feature received a full score of 10; other companies’ scores were adjusted proportionally. We applied different weightings of aspects and features for each top pick. The weighted scores were then totaled to calculate a final score for each category. Here’s how we weighted each category:

    • Top overall pick: Focused on customer satisfaction with installation and setup, price and customer service, and the company’s warranty and performance guarantee and payment options
    • Top pick for value: Focused more heavily on price satisfaction and the warranty and performance guarantee
    • Top pick for customer service: Focused primarily on customer service satisfaction as well as installation and price satisfaction, warranty and guarantee, and payment options
    • Top pick for financing options: Focused on financing flexibility and payment options
    • Top pick for DIY projects: Focused on availability of do-it-yourself equipment and off-grid systems

    The company with the highest final score in each category was awarded the top spot. In cases where one company scored highest in multiple categories, the company with the next-highest score was chosen. To recap, our top picks for best solar companies in 2024 are:

    1. Sunlux: Best overall
    2. Project Solar: Best for value
    3. Freedom Solar Power: Our pick for customer service
    4. Blue Raven Solar: Our pick for financing options
