This year's net metering rules could throw cold water on Californians' interest in going solar. But even with the less favorable rules, solar panels can make sense.
California is a leader in rooftop solar panels. Pv Power Generators
California has more rooftop solar panels than any other state; it's not even close. And for good reason: Not only does the Golden State have the most people, it also has a history of policies designed to encourage people to go solar.
While recent changes to the state's net metering regulations might put a dent in the state's solar growth, there are plenty of reasons to consider swapping much of your above-average electric bill for a set of solar panels. But making that choice is just the first of many: You also have to pick an installer.
We've compiled a list of the top installers in California, and rounded up some advice on how to shop around to make sure you're getting a good deal on something that should power your home and your life for decades.

Like the rest of the industry, ADT doesn't offer much pricing info up front, but they do offer a price match guarantee. While we don't have a ton of details about that guarantee, it makes your ADT quote even more flexible.

It's the only company we've reviewed that offers 25-year warranties for the workmanship on its installations and against leaks caused by it.

Just remember to add the cost of Palmetto's monitoring service in to your payback period calculations.
Arizona, California, Colorado, Florida, Georgia, Illinois, Maryland, Massachusetts, Michigan, Missouri, Nevada, New Jersey, North Carolina, Ohio, pennsylvania, Rhode Island, South Carolina, Texas, Utah, Virginia

If you're looking for top-of-the-line solar panels, SunPower is you best choice. But don't write them off if you're looking for a less flashy installation that will get the job done. This year it started installing Qcells panels, which should make an installation from the longest-tenured company on our list more available to more people.
SunPower Solar offers top-of-the-line solar panels and strong warranties. The solar panels SunPower offers have industry leading efficiency marks (22.8%) and a warranty that guarantees at least 92% production after 25 years. It earns an A-plus rating from the Better Business Bureau. SunPower now installs batteries in four sizes, all of which come with strong warranties.
SunPower's solar panels might be a bit more expensive than others (though accurate pricing industry wide is hard to come by). The company has said it plans to continue rolling out more accessible solar solutions and started installing solar panels from Qcells this year.

If you're planning on addressing energy efficiency first, working with Elevation allows you to keep the whole process with one company.

It installs Qcells solar panels, among other brands, and battery brands including Enphase and Tesla.

Where you might miss out is customer service. discussion online seems to suggest Tesla's service is a bit of a gamble.
Arizona, California, Colorado, Connecticut, Delaware, Florida, Georgia, Hawaii, Illinois, Maryland, Massachusetts, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, Oregon, Pennsylvania, Rhode Island, Texas, Utah, Vermont, Virginia, Washington
Solar panels from Tesla are likely to be the cheapest option where they are available. You can save thousands of dollars, without sacrificing on quality of equipment or the warranties that protect it.
What you might sacrifice is customer service. From delays to price changes, to slow responses, to system malfunctions, social media reports of negative experiences aren't hard to find, including some who regret their choice. This is true of all solar companies, but the quantity of reports concerning Tesla is concerning.
Momentum installs in 11 states without using subcontractors. While using in-house installers doesn't guarantee a better experience, it does suggest you're likely to get a more uniform experience from them. The fact that Momentum backs its installations with a 25-year workmanship warranty hints at a strong belief in their crews' ability.

Ben Delman, a communications director with Solar United Neighbors, a clean energy nonprofit, says a homeowner interested in solar should look for solar installers that are certified by NABCEP and have the proper licensing for their work. Reading online reviews from multiple sources can also help you get a better understanding of a company's reputation. A few places to start looking for solar company reviews are Google, Yelp and Angie's. Delman recommends looking for solar companies that have at least 20 to 30 reviews. If you know someone who has solar panels on their home, you can ask them for recommendations too.
Aside from certifications and reviews, there are a few other things to look for in a solar installer. A good installer, Delman said, will be able to:
A reputable solar installer should be able to answer any questions you may have, no matter how difficult those questions might be. Don't feel hesitant to ask for clarification on any project and pricing details. To get the best price possible, shop around for multiple quotes. Delman recommends getting at least three quotes before settling on an installer.

Here's a look at the average cash price for a 5-kilowatt system before factoring in tax credits and incentives, according to data from FindEnergy.com and the Lawrence Berkeley National Laboratory. Remember that the prices you're quoted may not exactly match the estimates and averages, which may vary for a number of reasons. The Berkeley Lab's estimates are for prices before incentives and including fees for financing, for example.
Even though the cost of solar panels has decreased in the last two decades, they're still a substantial investment . But several solar tax credits and incentives make solar more affordable, especially in California. One key solar incentive, net metering, was reduced in a utility commission vote last year. When that change goes into effect April 15, it's expected to increase a solar system's payback period from six years to 10. California also introduced time of use rates, which could make installing backup batteries more profitable.
The residential clean energy credit (previously known as the investment tax credit) is a federal solar tax incentive offered in California that credits 30% of the cost of a solar system back to consumers who buy solar panels. This solar tax credit was increased and extended due to the Inflation Reduction Act , passed in August. There is no cap on the federal tax credit, so you can claim the entire 30% regardless of the size of the system.
You can apply for the residential clean energy credit by including IRS Form 5695 with your tax return. The IRS provides instructions on how to fill out this form, or the best tax software can take care of it for you. Your savings from the tax credit will be included in your tax refund or used to offset taxes you owe.
There are various state and local solar incentives available in California, too. You can find a more comprehensive list through the Database of State Incentives for Renewables and Efficiency. Here are just a few you should know.
If you decide to invest in solar panels for your home, there are several financing options to make the purchase easier.
Cash: A big expensive project like solar panels requires a lot of cash. If you see solar power in your future consider saving money now. Regular contributions to a high-yield savings account can help pad your savings.
Solar loan: Many solar companies will offer third party financing. Shop around with different lenders, because your solar company's third party choice might not have the best terms or interest rate.
Home equity loan or HELOC: You can also consider a home equity loan or line of credit. These can save you on interest but your home is at risk if you fail to repay.
Mortgage: Another way to get the cash for solar panels is to refinance your mortgage. Fannie Mae's HomeStyle energy mortgage is designed to fund energy efficiency projects.
Solar panels are a big investment, so it's important to consider all elements that could impact whether they're right for you. Some installation aspects to consider include:

What is the California solar mandate?
The California solar mandate is a building code requiring all new residential home construction to have a solar photovoltaic (PV) system installed as an electricity source. This mandate went into effect on Jan. 1, 2020. It applies to single-family and multifamily homes that are up to three stories high.
Is solar power good for the environment?
Solar power has pros and cons, but generally, it is a more sustainable power source than coal or gas. Fossil fuel electricity sources emit greenhouse gasses, including carbon dioxide, into the air when burned. Burning fossil fuels for energy is the main driver of climate change and contributes significantly to air pollution. Scientists say we must rapidly transition away from fossil fuels to avoid the worst effects of climate change. Solar energy is a greener alternative to fossil fuels because it is renewable (the sun will always produce the energy needed to create electricity), and converting the sun's power into electricity for a home does not produce greenhouse gasses. While the manufacturing of solar panels has some impact on the environment, it is much lower over the panels' lifetime compared to the carbon emissions from fossil fuels.
Does California require home solar panels?
In 2018, California passed a mandate requiring new single-family homes and multifamily buildings up to three stories high to install solar panels. This mandate took effect in 2020 and requires new construction projects to include a solar system large enough to cover all of the household's energy needs each year based on the climate and square footage of the home. If the system includes a solar battery, the builder can reduce the system size by up to 25%. If you live in a home built before 2020, you are not required to purchase solar panels.
How can I find a solar installer in California?
With many solar installers available throughout the state, it can be tricky to choose the right company. If you're searching for a California solar installer, take the time to thoroughly review your options, read customer testimonials and get multiple quotes from different installers. You can also review CNET's picks for the top solar companies.
Is California offering free solar panels?
California households that meet certain income requirements might be eligible for free solar panels. California's Low-Income Weatherization Program (LIWP) offers free solar panel systems and energy efficiency upgrades to low-income California households. California residents can also apply for the Disadvantaged Communities - Single-family Solar Homes (DAC-SASH) program, which provides no-cost rooftop solar installations to income-qualifying homeowners in disadvantaged communities. DAC-SASH is run by Grid Alternatives.
What is the new solar law in California?
Pv Power Accessories California's new net metering policy (NEM 3.0), which went into effect on April 15, decreases the value of solar energy credits by 75%. This means California residents who interconnected a solar panel system after April 15th are compensated significantly less than those who were enrolled before then for their excess solar energy, making solar batteries an attractive alternative.
