Solar Power to Electrical energy using Photovoltaic Power System

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. But what exactly is a PV system and how does it work?

?

The solar PV system is composed of several parts. 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.

When sunlight hits the surface of a solar cell, it quickly causes the electrons to transfer to different bands in the cell which results in the buildup of voltages between two electrodes. A solar cell on its own can only release around 0.5 volt.

?

Since a single solar cell produces a very low voltage, solar cells are wired together to form a solar panel which is protected by a weatherproof enclosure called a laminate. Manifold modules are then attached 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.

?

Oftentimes the material used for making solar panels is silicon which are good semiconductors of electric devices. These modules yield up to 27% efficiency. In most cases, these modules last more than 25 years.

?

Now that the costs of solar PV systems have greatly reduced, it is best to invest in this energy system. Learn how to get quoted from reliable solar PV providers that will let you save up to 37% on installation. Seize this favorable circumstance to get rid of your monthly electric bills while making a huge payback to our environment.
