All about solar thermal collectors

...high as 200°C (395°F), and tube collectors can reach temperatures as high as 295°C (563°F). Glycol will break down and turn acidic at those temperatures, which can leave deposits and corrode system components. It is therefore important that panels have some sort of cooling component incorporated into their design, wh...
