The term "solar incentives" generally refers to financial incentives that are in place to encourage the use of renewable energy by making installing and using solar panels more affordable. You may qualify for different types of incentives, including cash back, discounts or monthly utility bill credits, depending on your situation. Certain incentives come from your specific utility company, county or municipality, some from the California government and others from the federal government. Some broad categories of solar incentives include:

  • Rebates: Your solar installer might help you claim a rebate, or partial refund of your purchase, for your solar panels. Counties or states will also sometimes offer limited-time rebates. The value of a rebate will usually be deducted from your total price before any tax credits are calculated.
  • Solar Renewable Energy Certificate (SREC): SRECs can be sold to your utility company (or other buyers) for cash that typically becomes part of your taxable income. Typically, a certain (small) threshold of energy production must be met before your solar system is eligible for SRECs or similar performance-based incentives. These kinds of incentives are typically handled by your state government.
  • Net Metering: You can sign a net metering agreement with your Hillsborough utility company, that may apply to all or a percentage of the excess electricity your solar panels generate. They will then deduct this value from your monthly utility bill.
  • Tax Exemptions: Sales tax exemptions go into effect at the time of purchase for your solar panels. Property tax exemptions allow you to ignore the added value of your solar system when you calculate the amount of property tax you need to pay on your home.
  • Tax Credits: Tax credits lower, dollar-for-dollar, the total amount of tax you owe the federal government. These are different from tax deductions.

Federal Solar Incentives

Federal incentives are the kind of incentives that you are most likely to have some familiarity with. A federal incentive many people are likely familiar with is the Federal Solar Investment Tax Credit (ITC). The ITC is a tax credit for a given percentage of the cost of your solar system.

The ITC applies towards solar systems installed after January 1, 2006, and under this program you can deduct from your taxes a percentage of the total cost of solar panels, labor, accessories and equipment. You can claim this credit for solar panels installed on a primary or secondary residence in the United States that you own. The original amount you could claim was 30% of the total cost, although certain projects may qualify for only 26%, depending on the details. There is no maximum amount you can claim.

Your local Hillsborough solar panel installation expert can offer more information about the ITC and how it may apply to your situation.

In August 2022, the ITC (now titled the Clean Energy Credit) was bolstered by the passage of the Inflation Reduction Act. The new Clean Energy Credit now runs until 2035. You are now eligible for a 30% credit for solar systems that began installation on or after January 1, 2022, and will be done by December 31, 2032. The credit will then be decreased by a few percentage points every year until it expires. Starting in 2023, the expansion to the program will also make it easier to get credit for energy storage systems.

More information about the new Inflation Reduction Act can be found here. Your local Hillsborough solar panel installers are the best people to answer your questions regarding the new Clean Energy Credit and how it applies to you.

State & Local Solar Incentives

Rebates, tax credits and more might be provided at multiple levels. In addition to federal solar incentives, there are often state and local ones, too. These incentives may be provided by the California government, or by your county or municipality. Some are available for a limited time, while others are ongoing.
