Solar thermal products amplify heat energy from the sun to provide some of the most affordable, efficient, and environmentally responsible ways to meet the demand for domestic hot water.
Tax Incentives: 30% Federal tax credit.
Return On Investment: 3 to 6 years
Ideal Location: South facing wall of building
Size: To size your solar water heating system, determine the total collector area as well as the storage volume you'll need to meet 90%–100% of your household's hot water needs.
Heating Your Water
A solar hot water system is really quite simple. You're using the sun's energy to heat a solar collector full of solar fluid (or water, depending on which type of system you install), which then transfers that heat (or hot water) into your home's hot water tank. The circulation loop will continue as long as there is heat to be drawn from the collector. During times when there is little or no sun, a backup heating system will be activated to provide adequate hot water
(1) When there is sufficient heat to be drawn from the collectors, a controller automatically activates pumps.
(2) Heated solar fluid is then circulated from the collector,
(3) through a heat exchanger where its heat is transferred to
(4) water in the storage tank.
(5) The solar fluid is then pumped back to the collector to once again be reheated.
Rebates and Incentives: Federal and state tax credits increase the savings and affordability of a solar water system.
Public Perception: Today's consumer is keenly aware of global warming and the environment. Businesses that "go green" demonstrate to the consumer that it is a company that is taking proactive steps towards environmental preservation.
