How much can you save with a solar thermal system?

Anytime you install a major appliance in your home, you likely compare many types to see which is the best for you. When installing a solar thermal system, many homeowners like to try to determine just how much savings it will help them achieve. To estimate your solar thermal savings, consider these factors.

Every household has different needs and different usage. How much you will save with a solar thermal system may differ from your neighbor. Your savings depends on these factors:

• Your hot water usage
• How much solar energy you’re able to collect
• System performance
• Financing and incentives
• Conventional fuel costs for your backup system
• The efficiency of your backup system
• How often you rely on your backup system

For most homeowners, a solar thermal system will save anywhere from 50% to 80% on hot water heating bills. By comparing the monthly operating costs of a solar thermal system to a gas or electric water heater, you can see how these different systems measure up to one another. Remember- solar energy costs nothing, while utility power may increase in price each year.

To estimate the yearly operating cost of a solar thermal system, you’ll need to know the solar energy factor of the system, as well as the fuel type and costs for your backup system.
