Understanding Solar Thermal Systems for Industrial Applications

Solar thermal systems for industrial process are fundamentally different from solar panels common seen on residential dachtops. While photophotospic panels convert sunlight directly intro electricity, solar thermal collectors absorb solar radiation and convert it into thermal energiy - heat - which is then transferred to a working fluid such as water, thermal oil, or molten salt.
