How much does it cost to install solar hot water?

The cost of installing a solar hot water system can vary depending on the size of your system, incentives, and more.


In 2017, property owners in MA paid an average of $12,025.81 for a solar hot water system. Prices for solar hot water systems largely depend on how many solar collectors you install, as well as the size of your storage tank. Your hot water demand helps determine the tank size and number of collectors your system requires. In general, most homeowners can expect to pay somewhere between $11,000 to $13,000 for a solar hot water system.

These numbers are not taking into account available rebates; state rebates available from the Mass CEC (up to $4,500), the federal investment tax credit (30%), and the state tax credit (up to $1,000) can help to substantially lower your cost for a solar hot water system.
