Using the energy of the sun is a clean way to power the things we use. It's also sustainable as the energy never runs out. One hopes that technology will continue to progress so that everyone can use this energy. For now, you're planning to use it yourself, and that is a step in the right direction.
Keep your solar panels out of the shade. It might seem obvious, but your solar panels do need sun. Make sure that you are not installing them in the shade. Trim back the branches on surrounding trees if you need to. Failing to do so could cost you more than half your energy output.
Solar Water Heater is used for heating water with the help of sun rays.
Never walk on solar panels. They are fragile and can cost you a lot of money if you break them. If you have to walk on them, don't walk on the ends since these are the most fragile areas.
