The term "solar incentives" covers a range of financial incentives designed to make installing and using solar panels more affordable. This is done to encourage people to switch to renewable energy. These incentives might include upfront discounts, cash back or credit towards your monthly utility bill. Some incentives are given by the federal government, some by the state of California and some by your utility company, county or municipality. Categories of solar incentives include:

  • Tax Exemptions: These may come in the form of property tax exemptions, which can let you ignore the value of your solar system when paying property tax on your home. You could also look for exemptions on sales tax at the time of purchase.
  • Net Metering: Net metering becomes relevant after your solar panels are up and running. If you've signed a net metering agreement with your Ontario utility company, the company will subtract the value of the excess energy produced by your solar system from your utility bill each month. In some locations, this credit is dollar-for-dollar, while in others you might be refunded a percentage of the value.
  • Tax Credits: Tax credits are dollar-for-dollar reductions (not deductions) in how much in taxes you owe the government.
  • Rebates: Your solar installer might help you claim a rebate, or partial refund of your purchase, for your solar system. States or counties will also offer limited-time rebates at various times. The value of a rebate will usually be deducted from your total price before tax credits are calculated.
  • Solar Renewable Energy Certificate (SREC): SRECs are credits that can be sold to your utility company (or other buyers) for cash that normally counts as part of your taxable income. Generally, there is a small threshold of energy production to meet before your solar system qualifies for SRECs or similar performance-based incentives. SRECs and similar incentives are typically handled at the state level.

Federal Solar Incentives

When thinking about solar incentives, you probably think of federal incentives first. The Federal Solar Investment Tax Credit, or ITC, is probably the best-known federal solar incentive. The ITC offers a tax credit for a specific percentage of the cost of your solar system.

The ITC initially applied to 30% of the cost of installing a solar system, although that number has fluctuated slightly over the last few years between 26-30%. The installation date of your solar system will determine what percentage you qualify for. The total installation cost includes the panels themselves as well as the cost of equipment, accessories and labor. There is no maximum claim amount. The ITC can be applied to solar panels installed after January 1, 2006, on your primary or secondary residence. The residence must be owned by you and in the United States.

Have questions about how the ITC applies to your specific situation? Contact your local Ontario solar panel installer to get more information.

The ITC was renewed and increased in scope after the passage of the Inflation Reduction Act in August 2022. It's also now called the Clean Energy Credit. The Clean Energy Credit re-raises the credit up to 30% for solar installations undertaken between January 1, 2022, and December 31, 2032. At this point, the credit percentage will be reduced slightly each year until the end of the program in 2035. Starting in 2023, the expansion will also make credits for energy storage systems even easier to claim.

More information about the new Inflation Reduction Act can be found here. Your local Ontario solar panel company can answer your questions and explain how the new Clean Energy Credit applies to you.

State & Local Solar Incentives

Some solar incentives are often also provided at the state and local level. Similar to federal incentives, these could include rebates, tax credits and more. Certain incentives are offered for only a limited time, while others are ongoing. Your local solar incentives could come from the California government, or from your specific county or municipality.

Next Steps for Installing Solar in Ontario

You can apply for and receive solar incentives from the California government and the federal government, as well as from your local utility company. The increased availability of solar initiatives over the last 15 years has helped increase solar adoption nationwide.

Can I get any financial incentives when I add solar panels to a vacation home, rental property or commercial property?

Many solar incentives are intended to apply to a property you own that is located within the United States; most secondary residences fall into this category. Other solar incentives may be available for commercial properties, depending on the specifics.
