Maryland Solar Panel Savings Calculator

Maryland Solar Panel Savings Overview

Maryland receives an average of 4.3 peak sun hours per day, providing a solid foundation for residential solar energy. With electricity rates averaging 16.0¢ per kWh — near the national average — solar offers competitive savings. The typical Maryland homeowner with a 6kW system can expect to save approximately $1,850 per year.

Solar Energy Production in Maryland

A standard 6kW residential solar panel system in Maryland produces approximately 7,534 kWh per year. This accounts for a system efficiency factor of 80%, which includes panel degradation, inverter losses, and temperature effects. While 4.3 peak sun hours is modest compared to sunbelt states, modern high-efficiency panels can still produce meaningful energy savings in Maryland.

Maryland Electricity Rates and Solar Context

The average residential electricity rate in Maryland is 16.0¢ per kWh according to EIA data. This rate is near the national average. Combined with Maryland's solar resources, homeowners can expect a payback period of about 8 years. With utility rates increasing annually, your solar savings grow each year.

Maryland Solar Incentive Programs

SREC program (~$60/SREC). Property tax exemption. Sales tax exemption. Federal 30% ITC. All Maryland residents are eligible for the federal 30% Investment Tax Credit (ITC), which reduces the cost of a solar system by 30% of the total installed price. Maryland also offers full retail net metering, allowing homeowners to earn credits for excess solar energy sent back to the grid.

Net Metering in Maryland

Maryland has full retail net metering, which is a significant financial benefit for solar homeowners. Under full retail net metering, you receive credit at the full retail electricity rate for every kilowatt-hour of excess solar energy you export to the grid. This is the most favorable policy for solar homeowners.

Best Cities for Solar in Maryland

The best cities for solar panels in Maryland include Baltimore, Columbia, Germantown, Silver Spring, Waldorf. Solar production can vary by location within the state due to differences in cloud cover, local shading, and microclimates. Southern-facing roofs with minimal shading produce the most energy. Homeowners in Baltimore and Columbia can typically expect production close to the state average of 4.3 peak sun hours per day.
