Great addition to Rhode Island solar family

These homeowners in the Rhode Island town of Westerly installed a 30 SunPower panel system that covers 81% of their annual electricity usage. That’s like getting a rate cut from the $0.19 per kilowatt-hour (kWh) that they were paying National Grid down to just $0.06. Part of that comes from the incentives they will be getting, which includes roughly $16,000 REG income. Altogether, that makes their 25-year return on investment 216%.
