Firstly let’s try to answer, “What is Solar Thermal Technology?” Solar thermal is a technology that collects sunlight and converts it to heat, stores it, and later transforms it into electricity. In this technology, the panelson rooftops act as the collectors for sunlight and they heat the liquid in. .
Let’s first answer, “What are solar photovoltaic panels?” Solar PVs harness the PV technology to capture sun rays and directly convert the sunlight into electrical energy. These panels function best during the day when there is sunlight. .
The two technologies; solar PVs and solar thermal represent high energy technologies that guarantee you clean and green energy. Nevertheless, deciding the one to opt for, is quite tricky. While solar thermal is your perfect solution for water heating, Solar PV is. Quick Answer: Solar PV and solar thermal both harness energy from the sun but for different purposes. Photovoltaic (PV) systems convert sunlight directly into electricity, while thermal systems produce thermal energy for residential heating systems such as hot water or space heaters. [pdf]
