Solar Energy To Electricity Along Together Using Photovoltaic Power Systems

The use of renewable energy, like solar energy

, could be the answer to our problems regarding energy consumption and air pollution. When light energy hits the solar panels, it is taken in and then transformed into electrical energy by dint of the photovoltaic (PV) system. And by now youre asking exactly what is a PV system and does it work?

The solar PV system has quite a few components. There are solar panels sometimes called PV modules, mechanical and electrical connections, an inverter, mountings and a regulator for adjusting the electrical output. The basic functional unit of the entire system is an electrical device known as a solar cell or photovoltaic power systems cell.

A solar cell converts light energy directly into electricity by the photovoltaic effect. This process works by generating electrons, when the surface of the solar cell is exposed to the sunlight, which transfer to different bands in the cell causing a buildup of voltages between two electrodes. A solar cell on its own can only release around 0.5 volt.

Due to the low voltage produced by a single solar cell, several cells are assembled and interconnected to make a solar panel which is then sheltered by a weatherproof enclosure called a laminate. Multiple panels are then strung together to make a photovoltaic array. The electricity brought about by these panels are either hoarded, used directly or supplied into large electricity grids powered by generation plants.

An individual panel is usually incapable of sufficing the typical energy requirement of a household or a business hence a solar array is imperative. With an inverter attached to solar PV arrays, DC (direct current) is converted into AC (alternating current) which is what your lights and your appliances use.

Most of the time, silicon is the material used for making these solar panels which are good semiconductors of electric devices. In some cases, the efficiency of these PV modules could go up to 27%. In most cases, these modules last more than 25 years.

At this time when the costs of solar PV systems have greatly plummeted, it is best to invest in this power system. Get quoted now from reliable local suppliers of solar PV and find out how you can save up to 37% on installation. Let us take advantage of this great opportunity to find a cheaper energy source which is environmentally-sound as well.
