Solar: Maryland

Compare Electricity has developed a solar score for Maryland to help residents and businesses determine if a solar installation is a viable and cost-effective solution. The solar score is based on a combination of many different factors. Maryland is slightly below the national average for solar viability. Due to its geographical location, Maryland doesn't receive as much direct sunlight as most other states. The majority of the state receives 4-4.5 kWh of direct sunlight per square mile per day which is below the national average. An estimated 72% of homes have a roof that is viable for a solar installation and is unobstructed from direct sunlight. The average roof in Maryland can hold 5.3 kW of solar panels which is below the national average. Based on these factors, a residential solar installation for Maryland residents is generally a viable option. For more information, see the solar score graph below.
