Maryland has the potential to become one of the highest solar energy producing states with more than 200 sunny days per year and 182 solar contractors, according to the Solar Energy Industries Association. As green energy awareness increases, so do the government incentives to convert to solar panels in Maryland. Discover how Maryland residents can save money by taking advantage of solar incentives and tax credits.

Maryland’s Solar
Report Card


To determine a grade for each state, our researchers and solar experts analyzed data on crucial solar-advancement criteria from the following sources:

We determined a rank from 1 to 10 for each state in each category. We then combined the scores with the following weights and assigned an overall grade for each state. Our goal is to encourage those considering solar for their homes to get a basic understanding of solar potential in their areas and discover the best opportunities for clean energy available.

Examining Electricity Costs in Maryland

According to the U.S. Energy Information Administration (EIA), coal and nuclear power represent more than 80 percent of Maryland’s net electricity generation and most of that energy comes from out of state. This may explain the high cost of residential electricity at nearly $.15/kWh. The EIA notes that Maryland ranks 12th in the nation for residential electricity costs. To curb these costs, the state offers many incentives and tax credits to assist homeowners with the transition to clean, renewable energy.

Maryland Solar Panel Incentives & Policies

Maryland is aggressively seeking to increase its use of renewable energy resources. Its 2004 Renewable Energy Portfolio Standard (RPS) enacted requirements for electricity providers that will result in 20 percent of electricity generation to be from renewables by 2022. The RPS stipulates that 2 percent of the renewables used must be solar. Maryland offers a host of policies, programs, and incentives to encourage solar use among homeowners and businesses. Residents can find dozens of ways to save and earn money when they purchase a solar panel system.


Solar Renewable Energy Certificates (SREC)

Allows for the generation of SRECs by owners of solar energy systems, where one SREC represents 1 MWh of power, able to be purchased by electric utility companies in order to meet their alternative energy obligations.

Residential Clean Energy Grant Program

Provides financial incentives to homeowners who install solar water-heating, solar panels and geothermal heating and cooling systems to their primary residence. The grant amount differs per project type and capacity.

Parking Lot Solar PV with EV Charger Grant Program

Provides grants of up to $500 per kWh of solar panel electricity generation (requires an installation of minimum 75 KW capacity), with a maximum total grant of $250,000.

Game Changer Competitive Grant Program

Offers grants to cover costs to develop and support renewable and alternative energy systems. The awards range from $50,000 up to $250,000, up to 30 percent of total project costs.

Commercial Clean Energy Grant Program

Provides grants for the installation of solar power and geothermal energy systems by businesses, non-profits and local government agencies. Grant amounts vary according to the energy type.


Interconnection Standards

Laws enacted in 2007 created interconnection standards for electric generation systems of less than 10 MW, creating a four-tiered approach, defined through generation capacity.

Clean Energy Procurement

An 2001 executive order issued by the Maryland state governor designated a goal of at least 6 percent of state-consumed energy to come from “green” energy sources, along for an energy-use reduction of 15 percent by state buildings by 2010.

Net Metering

Requires all utilities to offer net metering tariffs for all alternative and renewable energy generation systems, up to a combined capacity of 10 percent of peak demand (1,500 MW).

Renewable Energy Portfolio Standard

Maryland’s RPS was enacted in 2004 (with multiple revisions since), and requires two percent of total electricity sales to come from solar sources by 2020, and a goal of obtaining 20 percent of sales from non-solar renewables by 2022.

Solar Easements and Rights Laws

Offers protections for solar energy system procurement, and prevents restrictions that increase the costs or reduce efficiency of solar panel energy collection systems.
