    We’ve talked to more than 2,000 Sunrun customers. Over a recent two-year period, 77% were satisfied with their installations and 73% were satisfied with the technology. Many tell us about significant savings on electric bills and would highly recommend the company to others. We also like that Sunrun’s leasing program lets you go solar without a huge upfront investment.

    • “The Sunrun team was very informative and educating. They were knowledgeable and punctual. I liked their professionalism and the overall feel was lowkey and easy going. They respected my wishes as a consumer and were very patient throughout the process.” — Jeff in Carlsbad
    • “My experience with Sunrun was absolutely great. My nephew works for them. I completely respect my nephew's opinion for the company that he would choose to work for, and that he liked Sunrun. … The installation was great … they stayed a little bit later, went over everything, how to read meters, and showed me how to put the app on my phone. Having solar is great. I look forward to no having a power bill every month.” — Kim in Carlsbad
    • “Our experience with Sunrun was good. I was already considering solar services and I listened to what Sunrun had to say. I had a couple of people come over. And I liked Sunrun's salesman a lot. He talked about the battery, and the other one didn't talk about the battery. And I wanted to put in a 160% of my use because my wife and I live here and we're getting older. Also, if we put the house up for sale, I figured the buyers will have children and they'll use more electricity. It'll be a good selling point. And the guy from Sunrun understood what I wanted to do. We also went on to everyone in the neighborhood with the three different associations over here and Sunrun got the best reviews. So, I use them.” — Beni in Carlsbad

    Make sure you read the fine print carefully. Some customers have said they are not satisfied with the contract and terms.

      Carlsbad solar panel buyers guide

      ConsumerAffairs has heard from thousands of Californians who have already gone through the solar panel installation process. Here’s what Carlsbad residents should look for when choosing a solar panel installation company. We’ll also touch on overall costs and ways to save with government incentives.

      Key insights

      A typical residential solar panel installation costs $15,941 in Carlsbad.

      Solar loans, leases and other programs make it easy to go solar with minimal upfront costs.

      Solar panel costs in Carlsbad

      A typical solar panel installation costs anywhere from $8,645 to $24,700 in California. Prices in Carlsbad are comparable, ranging from $8,505 to $24,300.

      This doesn’t include an energy storage battery, which sometimes costs as much as the panels: $7,000 to $18,000. A battery lets you store excess energy generated during the day and use it when your panels aren’t producing. It’s worth considering if California’s net metering rates continue to decline or if your area gets frequent blackouts.

      System size is the other major solar cost factor. The average Carlsbad household needs a system with a capacity of 6.56 kW (kilowatt) to fully offset their electricity costs. Depending on how much energy you and your family use, you might need a smaller or larger one.

      How can I pay for solar panels?

      Getting solar panels is like buying a car. Most people pay cash, finance or lease. Similar to leasing, a power purchase agreement (PPA) lets you get the benefits of solar without actually owning the equipment.

      • Solar loans work like any other type of loan. They have relatively low fixed interest rates. Once you pay it off, you own your system outright.
      • Solar leases 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.

      Is solar worth it in Carlsbad?

      Solar panels are generally worth it in California if you like the idea of lowering your monthly utility bills. With good planning, solar can save money and provide energy independence in the long run. On average, Carlsbad homeowners with solar panels can avoid $56,877 in total utility costs over 25 years.

      Homeowners with solar panels typically save $20,000 to $90,000 over 25 years.

      Solar power can be a good financial investment in San Diego County because of high electricity prices and available incentives. However, before deciding, you should consider the effects of new NEM 3.0 rules, the potential benefit of adding solar storage batteries and how much sun your home gets.

      For a lot of homeowners, the main drawback is the high upfront cost of purchasing and installing the panels and equipment. Assuming an upfront purchase, it takes about 5 years to break even (when your savings with solar panels make up for the cost).

      Others go solar for the environmental benefits. The impact of a single homeowner installing solar panels may be relatively small. Still, when enough people in a city like Carlsbad go solar, the cumulative reduction in air pollution can be significant.

      Potential roof problems

      As a rule of thumb, if your roof is more than 10 years old, consider fixing it before going solar. Installing solar panels on an old roof might mean you have to remove the panels, replace your roof and then reinstall the panels again. This is an expensive and frustrating process.

      How to find a reputable solar company in Carlsbad

      In our experience, the best solar companies in California have a few things in common: lots of experience, reliable equipment and transparent contracts. Here are some hiring tips.

      • Check certifications: California requires solar contractors to hold a C-46 licensing classification, which you can check through the Contractors State License Board. We also recommend choosing an installer certified through the North American Board of Certified Energy Practitioners (NABCEP).
      • Read reviews: Avoid companies with recurring complaints about misleading sales tactics, equipment failures, billing issues and lack of communication.
      • Ask questions: Do you need a solar storage battery, electric vehicle (EV) charger or critter guards? How does this affect overall pricing? What if your system needs maintenance? If you don’t understand something about the payment terms, warranty or ongoing services, ask for clarification.

      Carlsbad solar FAQ

      How does the federal solar tax credit work?

      The federal solar investment tax credit (ITC) is a significant incentive for most homeowners going solar. It reduces your federal tax liability by 30% of how much it costs to install solar panels.

      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.

      Don’t get confused: 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. Any unused portion rolls over to the next tax year. However, it’s possible to get a refund check if the ITC credit reduces your taxes to the point where you overpaid during the year.

      Are there any other solar incentives in Carlsbad?

      Residents can also take advantage of statewide solar incentives in California, including Self-Generation Incentive Program (SGIP) rebates for homeowners who install battery storage systems with their solar panels.

      • California Energy Commission: The California Energy Commission(CEC) offers various incentives and rebates, including incentives for solar water heating systems and energy efficiency upgrades, which can be combined with solar installations to maximize overall savings​.
      • Net metering: In California, net metering lets homeowners with solar panels send excess energy into the grid in exchange for credits on their utility bills. These credits help offset future energy costs, reducing overall electricity expenses and making solar energy more affordable.

      Will solar panels increase my property taxes?

      No. Under California law, solar installations are exempt from property tax reassessments, meaning the value added to your home by solar panels won’t increase your property taxes.

      Is my house a good candidate for solar?

      A relatively slanted roof with plenty of unshaded space is best. The worst place to install would be on north-facing roofs, especially if those roofs have a high pitch (very steep). Here are a couple of other questions to ask yourself:

      • How much sunlight do I get? Carlsbad gets a good amount of sunlight. The state averages 5 to 7.5 peak sun hours every day. However, if you have a lot of shading around your house, whether from trees or tall buildings, the panels might not get enough sun to power your home.
      • How old are my appliances? Getting your electrical loads as small as possible before going solar means you’ll need a smaller system, which will be cheaper overall. If you have older electrical appliances, upgrade those before investing in solar panels.

      As long as your house is a good candidate for solar, it’s at least worth considering. We suggest using NREL’s PVWatts Calculator to estimate how much electricity a solar panel can produce over a year on your house. Project Sunroof is a reliable online solar savings estimator.

      What are the different types of solar panels?

      Monocrystalline and polycrystalline are the most common types of solar panels used in residential installations. In general, monocrystalline panels are considered the best bang for your buck. Cheaper solar panels are typically polycrystalline. The key difference is in materials and efficiency: Monocrystalline panels use pure, single silicon crystals, while polycrystalline panels are made from melted silicon fragments, resulting in different efficiency levels.

      Solar panel efficiency is a measure of how well a panel makes electricity. Standard efficiency rates range from 19% to 23%, which means 19% to 23% of the sunlight that hits the panels gets converted into electricity. The more efficient the solar panels you buy are, the fewer panels you need. While more efficient panels cost a little more, you save by buying fewer panels.
