Solar, wind and water are the cleanest energy sources in the world. They do not pollute the environment. Solar photovoltaic is the use of solar panels to convert sunlight into electricity. The three main components needed to make up a solar power station are a solar panel, a battery, and a voltage regulator. Because it wasn't any time there will be sunshine, there is no sunlight, solar panels will not electricity, so you need to use batteries to store the solar panels to power, for there is no sunshine when use, because the sun sometimes strong and sometimes weak, the current is not very stable, the voltage regulator is needed for a stable output voltage and output current.
