Solar power in California
Last fact-checked on March 12, 2020, by Jame Bond-James Bond
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 on their homes.
The Golden State also has some of the most aggressive greenhouse gas emission goals in the nation. California’s renewable portfolio standard requires utilities to derive 60% of their retail electricity from renewable sources by 2030.

per year per 1kW of peak DC
(direct current) capacity

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 26% federal solar tax credit and the net metering law.
Many upfront utility-based incentives that were established under the California Solar Initiative are now exhausted for residential customers and are nearly exhausted for commercial customers.
However, the case for investing in solar has never been stronger due to reductions in the price of solar systems helping to compensate for the lack of some upfront rebates.
Net metering in California (NEM 2.0)
Since 1996, utility companies in California have been required by the California Public Utilities Commission to offer full 1-to-1 net metering (NEM) to their customers. This means that utilities are required to give you the full retail value for each unit of solar power you personally generate and send back into the grid.
In 2016, California instituted NEM 2.0. NEM 2.0 brought three main changes to the previous NEM policy:
- Paying interconnection fees;
- A change to nonbypassable charges; and
- Requiring the use of time of use (TOU) rates.
Interconnection fees
Previously, customers were exempt from interconnection fees. Under NEM 2.0, utilities set a standard mandatory interconnection fee.
Interconnection Fees for Investor-Owned Utilities
| Utility | Systems 1 MW or smaller | System greater than 1 MW |
|---|---|---|
| Pacific Gas & Electric | $145 | Total cost of interconnection |
| Southern California Edison | $75 | $800 |
| San Diego Gas & Electric | $132 |
$800 |
Nonbypassable charges
NEM 2.0 requires nonbypassable charges to be paid on each kWh of energy a customer consumes from the grid (about $0.03 per kWh) at a metered interval determined by your utility. When you purchase electricity from the grid, you will be billed the retail rate of electricity plus the total nonbypassable charges. When you export to the grid, you will be credited at the retail rate, not including the nonbypassable charges. So, you can apply the credits you earn to future energy usage from the grid, but you will still pay nonbypassable charges on the kWh you consumed from the grid.
Example:
Let’s say you have 3 kWh credits. From 2:00 PM to 3:00 PM, you use 5 kWh, but your system only produces 2 kWh. This means you consumed 3 kWh from the grid. You will be charged on your bill for nonbypassable charges on the 3 kWh you consumed from the grid. But, because you had 3 kWh credits, you will not be charged for the electricity charges.
Time of use rates
The final big change of NEM 2.0 is the transition to TOU rates. Customers using TOU rates pay different rates for electricity based on the time of day. Utilities provide a default TOU rate that customers will be put on, but other rate plans may be available. Check your local utility’s website for the best TOU rate for you.
Property Assessed Clean Energy (PACE) Loan Program
California has taken advantage of PACE loan programs to meet their 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. This is a great option if you want to go solar but aren’t sure how long you will be staying in your current house.
California is home to CaliforniaFIRST, the largest PACE program in the US.
PACE loans are also available through the HERO program.
Property tax exemption
California homeowners can now save on their property taxes with the installation of 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 exemps 100% of the assessed value of a solar system from residential property taxes.
What is the payback period for installing solar panels in California?
The payback period for installing solar panels in California is usually between 4 and 8 years. This is dependent 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.
