About Solar Hot Water
The Massachusetts Clean Energy Center (MassCEC) provides financial incentives to help with the installation costs of a solar hot water system at your home or business.
A solar hot water system captures heat from sunlight and circulates the thermal energy to your water tank. 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. These systems do not fully replace conventional water heaters, but can provide up to 80% of a building’s total hot water needs.
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.
The following are factors that affect the economics of a solar hot water system:
- System Design: Systems should be un-shaded and face generally south in order to maximize sun exposure. Systems should use certified equipment that is properly sized to meet the building’s specific heating load.
- Installation Costs: To familiarize yourself with residential project costs, please see the Commonwealth Solar Hot Water program’s Awarded Project Database.
- Fuel type offset: Because heating your water with oil, electricity or propane is more expensive than heating your water with natural gas, solar hot water systems replacing these fuel types have better payback periods than systems replacing natural gas.
By taking advantage of the Commonwealth Solar Hot Water rebates, federal and state tax credits, the MassSave HEAT Loan and/or other loans or financing options, you may be able to offset the upfront costs of your solar hot water system by more than 50 percent.
For more information on incentives that are offered for clean energy projects, please visit MassCEC’s Financing Clean Energy Projects page or the Database of State Incentives for Renewables and Efficiency (DSIRE).
You first need to find an installer. It is advised that you get multiple bids. For information on companies who have successfully completed two or more projects through the Commonwealth Solar Hot Water program, please see our list of Massachusetts installers.
Your solar hot water installer will conduct a site assessment and design a system specific to your home or building’s needs.
The installer will submit a grant application to the Commonwealth Solar Hot Water Programs on your behalf.
Commonwealth Solar Hot Water – On September 1, 2014, the Commonwealth Solar Hot Water program announced changes to the solar hot water construction applications. For more information, please see the "Commonwealth Solar Hot Water, Summary of Changes - September 2014" document below.
