What is Solar Thermal?
Solar thermal technology produces heat energy, as opposed to solar photovoltaics (PV), which produce electricity. Solar thermal systems can provide energy for domestic hot water, space conditioning (heating or cooling), or even rooftop electricity in certain applications. In the U.S., solar thermal technology is most commonly used to generate domestic hot water for use in all types of buildings
SHW Advantages
Small Footprint – DIG SHW collection panels are so powerful and efficient that fewer are needed to get desired results. Just one panel (25 bulb array) can generate up to 30,000 BTUs per hour, yet requires a rooftop footprint measuring only 3’ x 7’.
Ultraviolet Energy – DIG SHW panels do not need direct sunlight because they rely on the sun’s ultraviolet rays instead. That means our panels continue to pump out the BTUs even on overcast days and even on the very coldest days. The same cannot be said for other types of solar collector panels.
Thermal Efficiency – Our collection tubes are designed to be as efficient as possible in order to maximize production while minimizing heat loss. Our evacuated tubes act like an insulated thermos to prevent nearly all heat loss during the thermal energy collection and transfer process.
Affordability – Solar thermal energy used for space heat and hot water saves our clients an average of 30% to 40% in applicable annual energy costs. The savings, combined with federal and state tax credits and utility specific rebates, means that most of our systems pay for themselves within 3 to 5 years. DIG SHW systems are SRCC certified and ARRA “Made in America” compliant.
