Solar panels are one of the ways to convert solar energy into electricity for your home. The word solar panel is also used colloquially as a solar power generator. The photovoltaic modules in the panels are made out of PV cells, which have semiconductor materials semiconductor diodes and gallium arsenate. The main components of solar panels are the panels, mounting frame, solar cells and electricity generating device. You can have many solar panels on your roof or side of your house.

Understanding how solar panels work is important to get an idea about its advantages and limitations. The solar cells are called Photovoltaic Cells (PV) which changes the light into electricity by using certain chemicals. These cells are made out of semiconductor material called silicon, and these can be found in both thin film and rolled film forms. They are then connected in a frame that collects solar radiation, which is collected by specialized solar panels

The silicon contained in the solar cells heats up and creates an electric current. The current generated by the PV cells is routed to an inverter, which changes this direct current into alternating current (AC). The alternating current is then routed to power any household appliances. The size of the solar panels and the amount of power needed will determine how many cells are needed. For instance, a large solar panel containing several hundred of cells would be very expensive, while a small panel containing just twenty cells would be quite practical.

How solar panels work becomes evident when you realize that the current produced is directly related to the angle at which the solar cells are facing. As the sunlight hits the panels, electrons are knocked loose. The electrons flow in only one way; they must make a complete path through the silicon crystals to reach their destination and generate electricity. As the angle of the solar cell is related to the amount of sunlight hitting the panel, the amount of electricity generated increases as the angle increases. In the long run, the larger the solar cell, the more electricity generated.

While solar panels have been around for decades, advances in technology have allowed them to become much more efficient. New and innovative photovoltaic devices can store more electricity than ever before. Solar cells have also become smaller and easier to use. With so much more electricity being generated all the time, the cost of solar panels has become more affordable.

Photovoltaic cells are made from silicon, one of the most plentiful resources on earth. When sunlight hits the panel, electrons are knocked free. The electrons flow in one direction, and a direct current (DC) are created by passing an electrical current through the panels. This direct current (DC) is routed to power your lights, refrigerator, washing machine, and just about everything else you need or want to run your home on.
