Solar Tax Exemptions: Complete 2025 Guide To Sales Tax And Property Tax Savings

Yes, solar panels qualify for significant tax exemptions in the United States. Currently, 25 states offer sales tax exemptions on solar equipment purchases, 36 states provide property tax exemptions that protect homeowners from increased taxes despite higher property values, and all Americans can access the federal solar investment tax credit worth 30% of total installation costs. These combined exemptions can reduce your solar system’s total cost by 40% or more, making renewable energy investments substantially more affordable for homeowners nationwide.

Solar tax exemptions operate at three government levels: municipal/county sales tax relief, state property tax exemptions, and federal incentive programs through the ITC. For example, in states with 6% sales tax exemptions, you save $960 on a $16,000 solar system, while property tax exemptions prevent your tax bill from increasing even when solar panels boost your home value by an average of 4.1%. The federal ITC covers solar panels, installation labor, inverters, wiring, batteries, and even sales taxes in non-exempt states, but only applies to purchased or financed systems, not leased panels.

This guide breaks down available exemptions state-by-state, explains how each tax benefit works, calculates potential savings, and provides actionable steps to claim every dollar you qualify for in 2025.

Sales Tax Exemptions for Solar Systems

State governments designate solar sales tax exemptions as popular financial incentives. The Solar Energy Industries Association reports 25 states currently provide solar sales tax exemptions. 

Understanding this benefit matters: Most states impose consumer purchase taxes ranging from 2.9% to 9.5%.

Solar sales tax exemptions eliminate these taxes on solar panel purchases, solar battery systems, and related solar equipment. This waiver substantially reduces total purchase costs, enhancing solar investment affordability.

Consider this example: A state with 6% sales tax adds $960 on a residential solar design valued at $16,000, totaling $16,960. States offering solar sales tax exemptions allow you to pay only the base $16,000.

Property Tax Exemptions for Solar Installations

The Solar Energy Industries Association identifies 36 states offering property tax exemptions for residential solar system installations.

Here’s how it works: Solar panel installations typically boost property values significantly. Homeowners experience an average property value increase of approximately 4.1% after installing solar. States with renewable energy property tax exemptions protect homeowners from corresponding property tax increases despite rising home values.

Simply put: Your home’s value increases, but your property tax bill remains unchanged.

Federal Solar Tax Incentive Programs

Beyond state-specific benefits, a federal tax incentive applies to all Americans investing in solar power. The solar investment tax credit (ITC) currently delivers 30% value based on total solar installation costs, allowing homeowners to deduct 30% of upfront expenses. This tax credit encompasses:

• Solar panel costs
• Installation labor expenses
• Additional solar equipment including inverters, wiring, and other components
• Energy storage devices such as solar batteries
• Sales taxes paid for eligible solar installation expenses (applicable in states without sales tax exemptions)

The federal tax credit applies to purchased and financed systems, but excludes those leasing solar panels. Understanding how this credit works is essential, the U.S. residential solar tax credit changes after 2025, making timing critical for maximizing benefits.

For off-grid solar system installations, the federal ITC still applies, provided the system meets eligibility requirements and serves your primary residence.
