Solar thermal energy is a form of energy and a technology for harnessing solar energy to generate thermal energy or electrical energy for use in industry, and in the residential and commercial sectors.
Solar thermal systems are a way to satisfy heating needs by capturing the thermal energy of the sun for heating applications such as buildings, hot water or swimming pools. Tremendous amounts of energy currently go in to traditional heating applications that could be satisfied by solar thermal power. In domestic situations, for example, heating water accounts for approximately one-third of total energy use. Using solar energy for domestic hot water could save significant amounts of energy annually, meaning lower bills for homeowners and fewer emissions from traditional hydrocarbon-based grid power.
Developments in solar thermal technology have made these systems more reliable and more efficient and, therefore, a more practical choice for prospective adopters. Evacuated tube technology collector and flat plate technology collector can satisfy even large heating demands and are used by customers seeking more sustainable and cost-saving alternatives.
