Federal Solar Tax Credit

The federal solar tax credit, or investment tax credit (ITC), has been a keystone incentive for the solar industry. It was introduced in 2006 under the Bush administration’s Energy Policy Act and has been continually renewed by Congress since. 

Aimed to offset the initial cost of going solar, this nationally available incentive allows taxpayers to claim 26% of the total installation cost of a home solar project on their federal income taxes. With the average rooftop solar system starting at around $20,000, most homeowners see a credit of at least $5,000 when tax season comes around. 

As it stands, the credit will reduce to 22% in 2023, and it will be phased out completely for residential systems in 2024 (but it will stay at 10% for commercial systems). 

However, the Biden administration has made strides toward extending and even increasing the credit. The passing of the Build Back Better Act, which is being routed through Congress, would bump the credit to 30%, ensure it’s available for at least 10 years, and add a standalone tax credit for solar batteries. While this would be a huge step in the right direction, we’re unable to predict with any certainty whether the act will pass.

Net Metering

Since solar panels only generate electricity when the sun is shining, homeowners need a mechanism to spread out their energy consumption and stay powered when the sun is down.

Net metering is a billing arrangement through which surplus energy generated by solar panels is fed back to the local electric grid in exchange for credits from your electricity company. These credits can be used against your monthly energy bills.

Net metering programs are designed to incentivize customers to install solar panels, thereby reducing the total amount of energy that public utilities have to generate and distribute (a process responsible for about 25% of greenhouse gas emissions in the U.S.).¹ 

Net metering laws vary across the nation, and no two states’ policies look exactly the same. The rate at which a utility pays for your excess energy will be the largest factor in a net metering policy. Some credit customers at the retail rate, while others offer lower-value credits. Solar tends to be more popular in states with favorable net metering laws, as the incentive shortens a solar installation’s payback period and yields a higher return on investment.

Property Tax Exemptions

Most states and local municipalities offer property tax exemptions for renewable energy systems. This means that even though solar increases the value of your home, you won’t have to pay the additional property taxes that would otherwise accompany a home upgrade. 

The exact form of these exemptions will vary depending on the state. For example, a popular California solar incentive called the “Active Solar Energy System Property Tax Exclusion” ensures that adding solar panels doesn’t raise homeowner property taxes. Currently, 36 states offer some form of property tax exemptions for solar or other renewable energy systems.²

Sales Tax Exemptions

Depending on the state, your solar power system may also be exempt from sales tax. Most states have sales taxes hovering around 4 to 7%, which means homeowners could save over $1,000 on an average-sized solar system. 

Currently, 25 states offer sales tax exemptions for the purchase of solar equipment.³

SRECs: Solar Renewable Energy Certificates

As of 2020, 38 states and the District of Columbia have a renewable portfolio standard (RPS) requiring that a specified percentage of the electricity utilities sell comes from renewable resources. This incentivizes governments to reward residents who help the state reach its goal. 

If you live in one of these 38 states, your solar panels may earn solar renewable energy certificates (SRECs) for each megawatt-hour (or 1,000 kWh) of clean energy generated. To meet the requirements of a state’s RPS, public utilities will purchase these certificates from you in cash. The certificates then allow public utilities to count the clean energy you generate toward their own goals. 

Though complex to understand, SRECs offer tremendous upside in the form of additional income to both residential and community solar customers. Eligibility will vary depending on your location, but any reputable solar company will be able to walk you through the process of earning and selling your renewable energy certificates.

Top 10 States for Solar Energy Tax Incentives

As you consider whether to invest in solar energy, make sure you’re aware of any tax incentives specific to your state. If you decide to work with a local top solar company, it will likely provide you with assistance in claiming these financial benefits.

Certain states will offer their own additional incentive programs for adopting solar. In around 10 states, that comes in the form of a second tax credit similar in form to the ITC. These state tax credits cover a predetermined amount of the net cost of a solar energy system, usually between 10 and 40%, capped at levels ranging from $1,000 to $5,000. 

According to our research and analysis, the 10 states with the best solar energy tax incentives include:

  1. New York
  2. Rhode Island
  3. Iowa
  4. Connecticut
  5. Maryland
  6. New Mexico
  7. Colorado
  8. Massachusetts
  9. New Hampshire
  10. New Jersey

Is Home Solar Right for You?

We’ve noted some of the top states for solar tax incentives, but it’s worth noting that there are plenty of other states that offer net metering, rebates and other financial incentives. Additionally, we recommend checking for financial incentives from your city/municipality or your local utility company.

While solar installation can cost a lot of money on the front end, these incentives can make it worthwhile — especially if you live somewhere with ample sun exposure, where you can really take advantage of your system’s energy-producing abilities. To see how much it would cost to install a solar panel on your home — and how much you can save with incentives — fill out the form below and get a free quote from a certified solar company near you.

FAQ: U.S. Solar Incentives

At EcoWatch, we routinely get questions from readers about solar programs from the federal government and state legislatures. Here are some of the more common queries, along with our answers. 

Will solar incentives increase?

Climate policy and energy independence have taken center stage in recent years, and many hope this will result in expanded incentives for adopting solar. However, most current incentives were set long before the cost of solar reached the low levels where it currently stands. Seeing as costs are low and demand for renewable energy is high, we wouldn’t recommend waiting to install a photovoltaic system in hopes of seeing better solar incentives. 

Are there any government grants for solar panels?

The solar investment tax credit, or federal ITC, is a tax credit worth 26% of installed solar electric costs. A number of states will offer their own incentives for solar panels as well, coming in the forms of additional tax credits, rebates, grants or low-interest loans. Local utilities may also offer their own special incentives for solar depending on your area. 

How many years can I claim the solar tax credit?

The federal tax credit is worth 26% of the total cost of your installation and can be applied to your federal income tax liability. If you plan to claim the ITC but you don’t owe any taxes during the calendar year, the tax credit does roll over, but only for up to five years. 

So, if you don’t anticipate paying a few thousand dollars in income tax over the next five years, you won’t be able to take full advantage of the ITC. 

What is the best way to finance solar?

Purchasing solar in cash will always provide the biggest return on your investment. However, financing solar through a loan is the best way to make the switch if you can’t afford the full cost upfront.

Solar loans have become a popular and practical option for homeowners going solar. Though interest rates may tack on a few thousand to your total costs, financing solar via a solar loan provides far more long-term savings than a solar lease or power purchase agreement (PPA).
