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. Smith Sustainable Design’s team of solar thermal installers can help you calculate the yearly operating costs and payback period for a new system. Solar thermal systems are a great alternative to gas and electric water heating, and can help you save hundreds on your water heating bills each year. Contact us to learn more.
