Compare Electricity has developed a solar score for Pennsylvania 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. Pennsylvania is slightly less viable for residential and business solar installations than the national average. This is because the state typically experiences less direct sunlight than the national average. Most of Pennsylvania receives 3.5-4 kWh of direct sunlight per square mile per day which is below the national average of 4.7 kWh/sq. m/day. Eastern PA receives slightly more direct sunlight throughout the day than western PA on average. An estimated 63% of Pennsylvania roofs are viable for solar installation which is slightly below the national average of 70%. This is due to PA homes having slightly smaller roof sizes (420 sq ft on average) and obstructions like trees and buildings in the way of direct sunlight. However, in general, a residential or solar installation is still a viable option in PA. You should consult with a professional on your personal situation to see if solar is right for you.
