Compare Electricity has developed a solar score for Massachusetts 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. Massachusetts is below the national average for solar installation viability. Most of the state receives 4-4.5 kWh of direct sunlight per square mile per day which is slightly below the national average. A few western parts of Massachusetts receives 3.5-4 kWh/sq.m/day. Only an estimated 67% of rooftops in the state are viable for solar installation. Meaning, they are large enough to hold several solar panels and are unobstructed from direct sunlight. In total, there is an estimate 13,000 mW of available solar installation in Massachusetts. If all this available space were implemented it would save 6.4 million metric tons of carbon emissions. In general, a residential solar installation is a viable option for Massachusetts residents but only a professional can tell you if your property is suitable.
