Virtually any business that uses hot water can save with solar water heating. Businesses or properties that use a great amount of hot water, such as those that use water for manufacturing, laundering, dishwashing or sanitization can substantially reduce costs. Additionally, solar water heating systems can be used for building heating and cooling, industrial and heat processes, swimming pool heating and other applications that require the heating of water.
Purchasing a solar water heating system is an investment. The expense typically occurs at the beginning of a project, and the savings can offset the cost over the system’s lifetime. The system’s cost and savings depend on several factors, including:
Installing a solar water heater typically reduces your cost of heating water by 50-80 percent. The payback can occur in just a few years. To get a better sense of costs and savings, a local contractor can:
Yes, the California Solar Initiative Thermal program through PG&E provides incentives up to $800,000* to eligible business and multi-family customers who install a solar water heating system. **The incentive amount is based on the size and performance of the system, and how much natural gas is saved. The more water you heat with the sun, the larger your rebate. Your contractor typically determines the incentive amount and submits the rebate application.
You may also qualify for a 30 percent federal tax credit for the installed cost of the system. Consult your personal tax advisor for more info.
You can finance the installation of a solar water heating system in many ways, including:
*The final rebate amount is based on the estimated savings as determined by your contractor.
**The system must heat water with a natural gas water heater or boiler. Customers who heat water with electricity or propane are not eligible.
