PV solar cells are improving 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.
The cells have to be protected from the elements, and so they are usually encased between glass. Solar cells are usually connected in what is called a series inside the module. A series refers to the order in which they are connected. When circuitry is connected in a series, the same current is allowed to flow through all of it.
When cells are connected parallel, then higher currents are yielded. Modules can be connected in arrays by parallel, or by series until the DC voltage, and current necessary are reached. The power that is generated from the solar array is measured by 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.
Financial incentives are there for individuals and business owners to switch to solar energy as a form of renewable energy. This is a great time to make the conversion. New manufacturing materials and government incentives make it less expensive, and you can make a big difference to change the world at the same time. Do your part to save natural resources that are being depleted more and more every day. We are wasting renewable energy that is so plentiful we will never be able to use it all.
When you decide to get some pv panels for your alternative electricity, you should get the best person to install them.
