How Does Solar Energy Work

PV solar power is solar energy in the form of sunlight, which has been collected by a photovoltaic module, and converted into usable electricity.
Conventional silicon solar panels convert about 14 to 17 percent of sunlight into usable electricity. That isn’t much. Late in 2006, however, a new solar cell was introduced. Solar panels that utilize the new cell can convert into electricity 22 percent of the sunlight they collect. Theoretically, the maximum that the cells of a solar panel can convert is said to be around 26 to 27 percent of incoming sunlight.
Each photovoltaic cell in a PV solar panel is a semiconductor. When sunlight hits those cells, a certain part of the sunlight is absorbed by those silicon cells. The cells take in that part of the sunlight’s energy. The cells then transfer the absorbed sunlight’s energy to the electrons in the silicon. The electrons begin to flow, and this creates an electrical current. Metal contacts built into the top and bottom of the PV cells draw off that current and it is sent to the grid or battery. It is now usable electricity. The power grid sends it on its way, if you have used an on-grid connection. If you are using a battery, it is stored in the battery awaiting your need.
PV solar power is being used increasingly with great success, and while it is true that cloud cover can affect it, the cloudy country of Germany leads the world in successful use of solar panels.
