Technologies harness heat
This helps out your central heating system, and cuts your fuel bills. Water is pumped through pipes in the panel. These technologies harness heat from the sun to provide electricity for satellites, but these days many of us own calculators powered by solar cells. Solar photovoltaic and concentrating solar power technologies are also being used by developers and utilities to produce electricity on a massive scale to power earth4energy cities and small towns. Businesses and industry also use these technologies to diversify their energy sources, improve efficiency, and save money. The most commonly used solar technologies for homes and businesses are solar water heating, passive solar design for space heating and cooling, and solar photovoltaics for electricity.
