Solar power in California
Last fact-checked on April 14, 2023, by Catherine Lane
California is one of the best places in the nation to install solar panels. A combination of high average sun exposure, expensive utility rates, the solar tax credit, and the state's net metering law means homeowners can get an excellent return by installing solar panels.
But, California's net metering rules have changed, causing solar panels to save less money than they have in the past. Don't worry, Californians can still see an excellent return on investment under the new rules, and battery storage is now a more economical choice.

What are the pros and cons of installing solar panels in California?
The biggest advantages in California for installing solar panels are the current net metering program and the 30% federal tax credit. There are also a number of incentive and financing programs for low-income households so everyone gets a chance to benefit from solar!
The disadvantages of going solar in California are pretty slim. However, with the recent net metering policy change for customers of PG&E, SCE, and SDG&E mean homeowners that install new solar systems will save less than before.

How much electricity will solar panels produce in California
Solar panels produce different amounts of energy in different locations.

per year per 1kW of peak DC
(direct current) capacity
For more information about how your location, roof direction, and roof tilt affects solar power production use the solar panels calculator and enter your zip code.

What rebates, solar tax credits, and other solar incentives are available in California?
What solar incentives and tax credits are available in California?
The two main incentives to install solar in California are the 30% federal solar tax credit and the state's net metering law.
Many upfront utility-based incentives that were established under the California Solar Initiative are no longer available for residential customers.
Despite limited utility incentives, the case for investing in solar has never been stronger due to reductions in installation prices and higher-than-ever electricity rates!
Net metering in California (Net Billing)
Net Billing, or NEM 3.0, is the newest set of rules for how investor-owned utilities bill solar customers. Despite being a historically solar-friendly state, California's new rules lower solar savings for homeowners. Under the new program, solar homeowners must use updated Time of Use rates that charge very high rates during peak hours and much lower rates during off-peak hours.
Not only that but excess solar energy produced will be credited at a rate of about $0.05 per kWh. This is much lower than California's average electric rate of $0.30 per kWh.
But, even with these changes, installing solar panels is still a solid investment. The payback period pencils out to about nine years, and the changes make it so systems paired with batteries also pay for themselves in nine years.
Property Assessed Clean Energy (PACE) Loan Program
California has taken advantage of PACE loan programs to meet its emission targets. These loans are paid back through an increase in your property taxes and are attached to the property, not the property owner. So, if you get a PACE loan and decide to move, the loan stays with the property, and the next property owner will continue to pay off the loan.
California is home to CaliforniaFIRST, the largest PACE program in the U.S. PACE loans are also available through the HERO program.
Keep in mind PACE loans are technically tax liens, and you could potentially lose your home if you don't properly keep up with payments. It's important that you understand every aspect of the contract before you sign it.
Property tax exemption
California homeowners can now save on their property taxes when installing residential solar systems. Typically, having a solar system on your property would increase your property taxes. However, The Property Tax Exclusion for Solar Energy Systems exempts 100% of the assessed value of a solar system from residential property taxes. This exemption is set to expire by the end of 2026.
What is the payback period for installing solar panels in California?
The payback period for installing solar panels in California is usually about 9 years. The actual time it will take for your solar panels to pay for themselves depends on the size of the system, the brand of solar panels you buy, the amount you were previously paying for power, and whether you lease or buy the system.
This represents an excellent low-risk investment.
