Solar Water Heater

Solar panels are very efficient at taking advantage of solar radiation. In our latitudes the sun generates up to 1000 Watts per m². With photovoltaic panels we can capture 200 W / m², with thermal energy it rises to 800W / m², four times more! Solar panels are much more profitable than photovolta…By: Low tech(…)
