Sunrun's leasing program lets you go solar without a huge upfront investment. There’s no initial charge for any panels or other equipment, installation or permits.

  • “All questions were answered, so I was happy with Sunrun. They were timely. I could talk with them and the work was good. If I got a problem with something, I gave them a call. Everything with Sunrun has been fine with me, so far.” — Ernest in Temecula
  • “I'm an environmentalist and getting solar services is the way to go. Signing up with Sunrun was really great. I had representatives all way down the line and everyone was very professional. … I live in Southern California so we have enough days of sunshine and it doesn't rain ever here. Ironically, it rained the night before the day of the installation, so the earth was wet and they couldn't do it. But, when they were able to do the installation, Sunrun did it very well in one day. Then, they called to see how happy I was. And I've been very happy. I feel like I'm helping the planet and my grandchildren. I'm saving money too. I would recommend Sunrun to anyone." — Beverly in Temecula

Temecula solar panel buyers guide

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

Solar panel costs in Temecula

A typical solar panel installation costs anywhere from $8,645 to $24,700 in California. Prices in Temecula are comparable, ranging from $8,260 to $23,600.

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 Temecula household needs a system with a capacity of 7.51 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 Temecula?

Solar panels are generally worth it in California if you like the idea of lowering your monthly utility bills. On average, Temecula homeowners with solar panels can avoid $57,873 in total utility costs over 25 years.

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 3.9 years to break even (when your savings with solar panels make up for the cost).

If you worry about your carbon footprint (and most of us should be), solar is also worth it for the ecological benefits. The environmental impact of a single homeowner installing solar panels may seem relatively small, but when enough people in a city like Temecula 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 Temecula

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 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.

Temecula 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 Temecula?

There aren't any widely advertised city-specific solar rebate programs currently, but it's worth checking with the city government for any potential pilot programs or future initiatives. 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.

Additionally, 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.

How does net metering work in Temecula

If your solar panels generate more electricity than you use, the extra is sent back to the Southern California Edison (SCE) grid through net energy metering.

NEM 3.0 reduced the value of excess generation credits in 2023. Currently, SCE credits you based on the "avoided cost" of energy, which is typically lower than the retail rate. This value changes with the time of day and year.

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 HOA allowed to restrict solar panels?

California’s Solar Rights Act prevents homeowners associations (HOAs) from restricting residential solar panel installations. HOAs can, however, impose minor restrictions as long as they don’t reduce the system’s efficiency.

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.

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? Temecula 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.
