One of the little known secrets about solar energy is you can build solar water heater systems yourself using cheap common materials. These systems can be used for your household hot water, to heat a pool, a hot tub, to heat your home or any other use. Up to one third of a home's energy bill can be from heating water. This can be greatly reduced with a solar water heater system or even eliminated. When you look at the low cost of building one yourself and compare it to what you are spending every month on your energy bill it doesn't take long to pay a solar water heater off. it's really a no brainer. Heating water is much more simple than generating electricity with solar energy. To generate electricity you need solar panels that are made out of more expensive materials can be costly to put together. To heat water all you have to do is leave it out in the sun. You can leave just about any substance in the sun and it will automatically absorb heat from the sun. A solar water heater uses this same simple principal only it magnifies the process by allowing the water to absorb the sun's energy to heat the water while insulating it so the heat will not escape. Unlike photovoltaic panels you don't need semi conductors and other expensive materials and technology. To heat water all you need is common plumbing and building materials that you can find at your local hardware store. Learn
