Solar Hot Water
Tapping into the sun’s power is a highly efficient, low maintenance, renewable hot water solution for all the sunny days ahead.
If you are looking for an affordable way to use solar energy in your home, solar hot water can be an excellent investment to reduce costs.
Protect the climate by using the sun for up to 80% of your water heating needs
Lower costs than heating water with oil, propane, or electric resistance
Installing solar hot water is a fraction of the cost of installing solar photovoltaic (electricity) systems
Solar hot water systems can be paired with any source of back-up water heating
Solar energy heats liquid circulated through collectors on your roof or on the ground. Heat from the liquid is transferred to a solar storage tank or boiler through a heat exchanger to provide hot water to your home. When needed, a backup source of heat will provide supplemental hot water.
Available roof or ground space | Good sun exposure | Medium to high hot water usage
“Financially, I think it’s a winner. Partly because the lifetime warranty of the tank pays for itself and partly because of the free energy.”
Alternative Energy Certificates (AECs): One-time payment provided to homeowners installing solar hot water. A two collector system could receive approximately 100 AECs totaling $400-$1,000.
If you live in a town served by a Municipal Light Plant (MLP) check your MLP’s website for incentives and rebates.
Inflation Reduction Act: Federal tax credit up to 30% of system cost.
Mass Save® HEAT Loan: Up to $25,000 at 0% interest over terms of up to 7 years.
Cost after incentives is estimated by subtracting AECs worth $1,000, Mass State Tax Credit and Federal Tax Credit from up-front cost.
Cost after incentives may be substantially lower if your household qualifies for income-scaled State and Federal rebates.

Do you want to save on your energy bill?
Solar hot water provides 80% of your hot water for free, dramatically cutting your home’s hot water heating bill.
Do you have available roof or yard space with good sun exposure?
Solar hot water requires good sun exposure for at least 5 hours a day for optimal production.
Do you have a pool?
Solar hot water pool heating systems are an environmentally friendly and an economical way to keep pool water heated to a comfortable temperature.
Are you looking for an affordable way to go solar?
After incentives, solar hot water’s net cost is approximately $6,900, much lower than solar electric (PV) systems. The 0% interest Mass Save® HEAT Loan will enable you to start saving money from day one.
