What Are the Available Solar Incentives in Maryland?
Solar owners in Maryland may qualify for various state and federal rebates and tax credits. We’ve highlighted the key Maryland solar incentives below.
- Federal Solar Investment Tax Credit (ITC): The federal solar tax credit allows you to claim 30% of your solar installation costs on your federal tax return. This rate will reduce to 26% in 2033 and 22% in 2034 before ending. You must purchase your system in full or take out a loan to qualify.
- Maryland Energy Storage Income Tax Credit: The Maryland Energy Storage Income Tax Credit provides a state tax credit of up to $5,000 to solar owners who install battery backup storage.
- Maryland Solar Property Tax Exemption: Maryland exempts solar customers from paying taxes on the increased home value from installing solar panels. Solar power equipment is also exempt from sales tax.
- Residential Clean Energy Rebate Program: Homeowners who install clean energy systems may be eligible for a $1,000 solar rebate from the Maryland Energy Administration.
- Net metering: All investor-owned utilities in Maryland must offer net-metering programs, which allow customers to get a 1-to-1 credit on their electric bill for any excess energy that their solar system sends to the grid.
- Solar Renewable Energy Certificates (SRECs): You earn one solar renewable energy certificate for every 1,000 kWh of solar energy you produce. You can sell SRECs to participating companies looking to invest in solar energy. You must be registered with the Maryland Public Service Commission (PSC) to participate.
We surveyed 1,000 recent solar buyers in early 2024 and learned that 64% used the federal solar tax credit, 32% enrolled in a net metering program, and 30% took advantage of a local rebate program.
- A few Maryland counties offer additional tax credits, including Harford County, Anne Arundel County, Baltimore County, and Prince George’s County. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) for more information.
Our Conclusion
We recommend getting at least three quotes from solar installers to compare pricing and services, as the price you’ll pay to go solar can vary significantly between installers. The providers listed above are an excellent place to start, but here are a few well-reviewed local Maryland solar companies to consider:
- Solar Energy World (Elkridge)
- Lumina Solar (Baltimore)
- Celestial Solar (Frederick)
- Solar SME (Annapolis)
- Aurora Energy (Columbia)
Our top pick is Palmetto due to its high-quality solar panels and its well-rated customer service. Whichever provider you choose, consider product selection, financing, warranties, performance monitoring, and customer reviews.
