solar panels easily reach up toward 200 degrees, and i’m trying to build a drain back solar panel to keep a green house warm,
does anyone know of inexpensive solar panel and pump that made of metal that will not be damaged by pumping hot liquid back into the panel
the design as i see it will be a small tank inside the greenhouse that pushed water into the panel at whatever temp is there and is heated and returned,
at some point, the water will be hot enough to start to damage an impeller so i would like to use metal. my concern with battery and inverter is mostly battery drain,
it will be a sort of bread box design if you are wondering about that, so that the water is able to keep the temp in the green house at least about 49 or so, (i hope)
