Solar Incentives by State [Updated April 2023]

Solar power is energy converted from the sun to thermal or electrical energy. Solar power is a renewable power source that is clean, inexpensive, and readily available everywhere in the world. Because solar energy comes from the sun, it represents an infinite source of energy.

The most common way solar energy is captured is by using photovoltaic (PV) solar panels. PV panels generate electricity directly from sunlight using semiconductors. When the silicon photovoltaic solar cell absorbs solar radiation, photons strike and ionize semiconductor material on the solar panel, causing electrons to break free of their atomic bonds. Electrons are forced to flow in one direction, creating a flow of electrical current. Only some of the light spectrum is absorbed, while other parts of the spectrum are reflected, too weak (infrared), or create heat instead of electricity (ultraviolet).

The first PV device was introduced in 1954 by Bell Labs in the United States. Interest in using solar energy increased during the 1970s because of the energy crisis. However, the cost of the implementation of these devices made large-scale adoption of solar devices impractical. Today, the price of PV devices has dropped dramatically, falling more than 59% over the last decade. Additionally, solar panels can be financed.

Solar power has several benefits such as eliminating electrical bills and avoiding utility inflation. The use of solar panels also protects the environment, creates jobs, and helps the U.S. become energy-independent. Additionally, many states offer tax incentives, rebates, and credits for installing solar panels on homes.

Types of Solar Incentives

State Tax Credits

State credits are similar to the Federal Solar Tax Credit, but the credit is instead applied to the homeowner's state taxes. Most often homeowners would be able to apply this to their taxes the year after their solar panel system was installed. State tax credit amounts vary widely from state to state.

Sales Tax Exemption

Some states offer homeowners a tax exemption on the purchase of solar panel system equipment. The homeowner pays zero sales tax on their solar panel system, which can result in a substantial discount, particularly on larger installations. Some of the states that offer this are Texas, Florida, California, and New Mexico.

Property Tax Exemption

This exemption prevents a homeowner's property taxes from increasing when they add solar panels to their home. Under normal circumstances, the installation of a home solar panel system is considered an upgrade that adds value to the home, and the home's property taxes increase accordingly. States with this exemption create a more appealing scenario for potential upgraders.

Net Metering

Net metering enables a homeowner to receive credit on their utility bills for sending excess solar energy generated by their home solar panels up the grid to the power company, which then redistributes that power to other customers.

Solar Renewable Energy Credits (SRECs)

Solar Renewable Energy Credits, more commonly known as SRECs, are offered by some state governments. SRECs are a measure of the benefits a home's solar system provides to the environment. The idea is simple: One SREC is generated for every megawatt-hour (MWh), or 1,000-kilowatt hours (kWh) of solar electricity a solar panel system generates, and utility companies then purchase those SRECs under the state’s Renewable Energy Portfolio (RPS) standards.

As of early 2023, SRECs are offered by Delaware, the District of Columbia, Illinois, Maryland, Massachusetts, New Jersey, Ohio, and Pennsylvania.

Solar Energy Incentives By State

State solar incentives are in addition to the Solar Investment Tax Credit that allows solar panel owners to recoup 26% of their equipment and installation costs for an unlimited amount. In addition to rebates, credits, and exemptions, states may offer net metering credits. Net metering credits solar electric users, reducing their electric bill because of the electricity they add to the grid. This helps to lower the electric bill and is a bonus for many homes using solar energy.

Some states also offer Solar Renewable Energy Certificates (SRECs) that are issued for every megawatt hour of energy produced. These act as vouchers that can be exchanged for energy savings on homeowners’ electric bills.
