Bob lives in a solar-powered home. Now that Amazon is carrying solar power accessories, maybe the tipping point is within sight for those of us who want to harvest our own energy.
When the winter comes, my power needs will go up (especially the blower motor on my gas furnace) while the solar power goes down. I’m starting to look at various ways to keep the house warm without hitting the grid too often or too hard. Running a space heater as a dump load would be one way. Using some form of solar air heating would be another.
ClearDome Solar offers several products to convert sun power efficiently into home heating. Check out their external forced-air heaters, solar heating drapes and radiant panels at their Amazon sales page.
