Welcome to The Sietch - Projects Build Your Own Solar Thermal Panel
After our first attempt at a home built proof of concept solar thermal panel, we were a bit disappointed with the results. It took about 4 hours before the thing started work, and was a bit costly (at over 50 dollars) to make. I knew it could be done better and cheaper. My first mistake with the first one was purchasing everything new. Another flaw from the first panel was using pond liner as our collection medium. We solved this problem by using a ready made collector. The last major flaw in our first panel was using plexiglas for the cover. We solved this problem by using good old fashion window glass. Now onto the project. Our local dump has a coolant removal program that has refrigerators and dehumidifiers that they remove old freon from. Make sure that the freon, or other coolant has been removed, and cut the grill off at the base, near the large coolant holder. I found a pane of glass and an old rubber door mat that made the perfect backing and front. Enjoy the hot water.
