Perhaps the solution for problems about energy consumption and air pollution would be the use of renewable energy like solar power. The light energy that hits the surface of the solar panels is absorbed and converted into our usable electric energy through the photovoltaic (PV) system. But what exactly is a PV system and how does it work?


The solar PV system consists of a number of components. PV modules which are also commonly called solar panels, mechanical and electrical connections, an inverter, mounting apparatus and a controller that regulates 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.


It is the solar cell which captures light energy and directly changed electricity by the process known as photovoltaic effect. When this surface of the solar cell is exposed to the radiation of sunlight, it generates electrons which are transferred between different bands in the cell resulting in the 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 generated by these panels are either stored or used directly or fed into large electricity grids powered by generation plants.


A single module usually cannot meet the energy requirements of a typical home or a business hence a solar array is formed. Solar PV arrays are often connected to an inverter to translate the DC (direct current) into AC (alternating current) which is what your lights and your household appliances need.


Most of the time, silicon is the material used for making these solar panels which are good semiconductors of electric devices. These modules yield up to 27% efficiency. Effective modules live for 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.
