The average cost to install solar on a home in Maryland is $3.98 per watt, with about 80 percent of systems installed for $2.90 per watt to $5.36 per watt. This is higher than the average solar cost in the South Atlantic Region of $3.95 per watt.
The average size of a solar system in Maryland is 10.4 kilowatts, which would cost around $41,400 without any federal, state, or local incentives.
1 kilowatt of solar PV in Maryland produces an average of 1,318 kilowatt-hours of electricity per year, so a 10.4 kilowatt solar system would generate 13,706 kilowatt-hours of electricity every year. An average household in Maryland uses 12,149 kilowatt-hours of electricity in a year.
With an average state electricity price of 14 cents per kilowatt-hour, this solar system could save a household in Maryland $1,924 each year. At this rate of annual savings, the system could pay for itself in about 22 years assuming no additional system expenses. This is less than the expected 30-year lifespan of a typical solar panel.
