What’s the Cost of Solar in Rhode Island?

Cost of Grid Power

Rhode Island's electricity prices average $0.18/kWh, well above the national average of $0.14/kWh. From 2017-2019 the state roughly tripled its solar power generation, accounting for about 3% of Rhode Island's net power generation. About three quarters of that came from small-scale PV installations.

The average cost of a 6kW (equivalent to saving more than 100 trees a year) solar power system starts around $18,000 in Rhode Island. That system would pay for itself through energy savings in less than two years. System life can span well over 25 years, and savings will improve with inflation. Over the live of the system, net profit can exceed $100,000.
