About Solar Thermal Hot Water

Solar thermal hot water systems use the energy of the sun to heat water for use in your home’s hot water system. Solar hot water systems reduce the usage of traditional water heating fuels (such as oil, electricity, or natural gas) and thereby reduce the amount you spend purchasing these fuels. Rebates of up to $3,500 are available, with higher incentive for low- and moderate-income customers. (From MassCEC website)
