PV cell continue to improve since their creation. Not only has their efficiency improved, but they are much less costly as well. It will take more than just one Photovoltaic cell to generate enough power for most things. For that reason, the cells are put together in groups that make up modules which are called solar panels. The following will discuss PV panels their past and the future of energy.
Photovoltaic is Greek meaning light, and electric. This word has been part of English since 1849. In 1839, the photovoltaic effect was actually discovered, but the first cell was not created by Charles Fritts until 1883. Fuller, Pearson, and Chapin were the first to create the first efficient cell in 1954.
One solar panel may be able to provide a small amount of power, but in order to provide a large amount of power, then panels are arranged in what is known as an array. An array is a multiple of modules that are able to make a large quantity of electricity; enough to light a house, or power plant. Until just recently, solar panels have been much too costly for the general consumer.
Cells need protection from the weather. This is why they are placed between two panes of glass. Inside each module, the cells are connected in what is called a series. Series refers to the pattern of the circuitry connection used. When the series pattern is used, the current will pass through all of the cells.
When a parallel connection is used, then higher currents can be expected. The modules in the array are connected by parallel, series or both until the DC voltage, and current required is met. The generated power is measured in watts or kilowatts.
To be able to use the energy that is generated, the electricity is processed through an electricity grid through an inverter. If the inverter is connected to a system that stands alone, then batteries can be used to store any energy that is not used immediately. There are many solar gadgets available that work on this same principle.
There are financial incentives available for individuals and business owners alike in many different countries to change to forms of renewable energy. The financial incentives for solar energy are especially great. This is the perfect time for a conversion of your business or home, and you can make a difference in the world at the same time. There is renewable energy being wasted every day, more than we can ever use, while our natural resources are being rapidly drained.
