While the cost of solar has declined significantly over the last decade, it’s still a sizable investment for home and business owners looking to lower their electric bills. In order to encourage the greater adoption of solar, the federal government, state and local governments, and even some utilities offer incentives to help make putting solar on your roof and powering your home with clean energy more affordable and accessible. These energy savings typically take the form of solar rebates, tax benefits, or performance-based incentives, and can reduce the cost you pay for solar from anywhere from 30 to 50 percent!

Major solar rebates and solar incentives

• Investment tax credits
• State tax credits
• Cash rebates
• Solar renewable energy credits (SRECs)
• Performance-based initiatives
• Incentives for businesses
• Subsidized loans
• Tax exemptions

Investment tax credit for solar

The federal investment tax credit (ITC) is far and away the best solar incentive. The ITC gives back 30 percent of what you paid for your solar project on your federal income taxes. Instead of a deduction, which reduces your taxable income (as would happen with any charitable donations you make in a year), a tax credit directly offsets what you would otherwise owe in taxes. In other words, instead of just being taxed on a lower income, the federal ITC offsets what you actually owe in taxes, and can even come back to you as a refund from the IRS if you've overpaid your taxes during the year (but it won't exceed your tax liability). Here are the specifics:

• 2016 – 2019: the energy tax credit remained at 30 percent of the cost of the system.
• 2020 – 2021: owners of new residential and commercial solar earned a credit of 26 percent of the cost of the system for their federal income tax bill.
• 2022 – 2032: owners of new residential solar can earn a credit of 30 percent of the cost of the system for their tax bill. Commercial solar systems will also be eligible for 30 percent until 2025, at which point the U.S. Department of Treasury will determine if the ITC will continue for commercial systems.
• 2033: owners of new residential solar can earn a credit of 26 percent of the installation costs of the system for their tax bill.
• 2034: owners of new residential solar can earn a credit of 22 percent of the installation costs of the system for their tax bill.
• 2035: there is no federal credit for residential solar energy systems starting this year.

State tax credits

Some states offer additional tax credits for installing a solar photovoltaic panel system, functioning much the same way as the federal ITC does but for your state taxes. These amounts vary significantly by state, but, when paired with the federal ITC, can really add up!

Cash rebates

Some states, municipalities, and utility companies offer up-front rebates for installing a solar panel system. Solar rebates are generally only available for a limited time and disappear once a certain amount of solar has been installed in your region. Solar rebates typically further reduce your system costs by 10 to 20 percent. Depending on the installer and equipment you choose, you could also receive addititional rebates for your system as well.

Rebates from state governments and/or utility companies

Rebates from your state and/or utility company can sometimes involve an intricate application process, but these types of rebates are often the most lucrative (making it well worth any extra effort).

The rules behind applying for state or utility rebates are typically stricter than requirements for other types of rebates. You may find that there are restrictions on the type of equipment you can use, on minimum or maximum system size requirements, or on which installers you can work with (and what certifications/licensing they need). An example of this is the Megawatt Rebate in New York: if you want to claim the incentive, you need to work with a pre-vetted, state-approved contractor.

Because of these regulations, applying for a state or utility rebate often requires the submission of detailed information about your solar equipment and system design, performance expectations, project costs, and/or installation company. More often than not, your solar installer will apply for these types of rebates on your behalf, or assist you with the process. Keep in mind that your local government and/or utility company may not pay you out for the rebate directly; sometimes, they give the rebate straight to your installation company, who simply subtracts the incentive amount from what they charge you. 

Rebates from installers

You may come across some installation companies offering seasonal rebates and other types of limited-time promotions to customers that move forward with them. If that’s the case, you likely don’t need to deal with a separate rebate application: you’ll simply sign the installation contract, and they’ll take the rebate amount directly out of your total costs.

Rebates from solar equipment manufacturers

Solar equipment manufacturers are increasingly offering rebates for installing their products. If your solar panel or inverter company has a promotion like this, you can likely apply for the rebate directly on their website. In order to receive the rebate, you may need to provide proof of installation, such as a photo, signed contract, and/or verification from your utility company that your system is up and running.

Some manufacturers also partner with EnergySage to offer rebates to people who install their products after finding an installer through our platform. If you’re claiming an equipment rebate through EnergySage, you’ll work directly with us once to receive the incentive once your system is up and running. 

Solar renewable energy certificates

Many states now have renewable portfolio standards, which require utilities to procure or generate a certain percentage of their electricity from renewable resources, including solar power. If you live in one of these states, your solar panels will create solar renewable energy certificates (SRECs) for the amount of electricity produced by your solar panel system. Utilities buy your SRECs as a form of compliance with state-level renewable energy requirements, given that each SREC is representative of the environmental attributes of your solar generation. Selling your SRECs can result in hundreds (or even thousands) of dollars more per year in income, depending on the SREC market in your state.

Performance-based incentives

Another common form of solar incentive program is the performance-based incentive, or PBI, which pays you a per kilowatt-hour credit for the electricity that your system produces. PBI programs are slightly different from SREC programs in one key way: while SRECs represent the environmental attributes of solar generation (i.e., emission reductions), PBI programs provide an incentive for the electricity produced itself (i.e., the kilowatt-hours of production). Unlike SRECs, PBIs don’t have to be sold through a market, and incentive rates are determined when the system is installed. PBIs can both replace or exist alongside net metering policies.

Solar incentives for businesses: accelerated and bonus depreciation

There are a wide range of solar incentives available to businesses, in addition to the ITC, rebates, SRECs, and PBIs. Depending on where your business is located, the various solar incentives available to your business could be worth more than 70 percent of the cost of your solar panel system!  

• Modified Accelerated Cost Recovery System (MACRS): a depreciation benefit that allows you to recover the value of your solar assets over an accelerated time frame; for solar this time frame is five years at the federal level. Some states also have MACRS available to businesses.
• Bonus depreciation: a depreciation-based tax incentive available to businesses that invest in solar, but you’re able to take the full benefit in the first year of your investment.

For businesses, you must choose between MACRS and bonus depreciation, depending on what works best for you and your company.

Subsidized loans

You may be eligible to finance your solar panel system purchase using a subsidized solar loan with a reduced interest rate. These loans may be offered by your state, a non-government organization, or your utility company, but are usually only available for a limited time.

Tax exemptions

Some states and municipalities do not include the value of solar panel systems in property taxes assessments. This means that, even though the value of your property has increased by the addition of a solar power system (by four percent on average!), your property tax bill won’t increase – it will remain the same.

In addition, your solar panel system may be exempt from state sales taxes, which can result in significant additional savings depending on your state’s sales tax rate.

The friendliest states for solar

Going solar is a good investment for most people anywhere, but some states are making it extremely worthwhile to invest in a solar system. The following states are making going solar so cost-effective that residents should be asking if they can afford to not go solar!

New York

New York has the widest range of solar incentives and programs available in the United States. In addition to the federal ITC, they offer:

• The Megawatt Block Incentive, a direct, generous incentive for solar energy available under New York’s ambitious NY-Sun Initiative. The program provides an up front dollars-per-watt ($/W) rebate for both commercial and residential solar panel systems;
• Net metering;
• A solar equipment tax credit of 25% or up to $5,000;
• And the NY Sun Initiative, an umbrella program for many solar initiatives including community solar.

There’s never been a better time to go solar if you’re from the Empire State!

Rhode Island

Though it may be the smallest state in the US, Rhode Island is at the head of the pack when it comes to enticing solar incentives. In combination with the ITC, they also offer: 

• A solar grant program that can save consumers up to $5,000;
• The Residential Solar Energy Property Tax Exemption, which means your property taxes will not increase as a result of the value your new solar panels add to your home;
• The Renewable Energy Products Sales and Use Tax Exemption, which means you will not have to pay any tax on your purchase of your new solar energy system;
• Net metering;
• And, National Grid’s Renewable Energy Growth program, from which consumers will receive 28.75 cents for each kilowatt-hour (kWh) their solar panel system generates for the first 15 years of their system.

With solar policies like this, it’s only a matter of time before the entire state installs solar panels!

Iowa

Residents of Iowa are in luck when it comes to solar incentives. When stacked with the ITC, theses incentives make it a no-brainer to go solar in Iowa:

• Favorable solar easement and rights laws that allow you to install even in the face of things like HOAs that might otherwise get in your way;
• Net metering;
• A five year property tax exemption for the value of your solar system;
• And, a sales tax exemption for electrical equipment that will save you six percent on your purchase price.

Connecticut

If you’re thinking about going solar, Connecticut is a great place to do it. On top of the ITC, residents are able to stack the following incentives:

• The Smart-E energy efficiency loan program of up to $40,000 for 5-12 years at a 4-7 percent interest rate;
• Net metering;
• The Sales and Use Tax Exemption for Solar and Geothermal Systems, which means that you won’t have to pay any taxes on the purchase of your system;
• And, the Property Tax Exemption for Renewable Energy Systems, which means you won’t have to pay any additional taxes on the increased value of your home as a result of installing solar.

Connecticut’s plethora of incentive options makes it an easy decision to install solar in the Nutmeg State.

Maryland

Mayland has set ambitious clean energy goals, and is backing them up with great solar incentives. Residents can take advantage of the ITC and the following incentives:

• The Maryland solar rebate program that will pay you $1,000 for installing a solar system;
• One of the best SREC incentive programs in the country;
• Net metering;
