PV Panels In The Past With Energy For Tomorrow

PV cells have improved a great deal since they were first created. They have become much more efficient, and much less expensive. More power is usually needed that a single photovoltaic cell can produce on its own. This is why photovoltaic cells are grouped together to form modules, or also known as solar panels. Continue reading to learn about PV panels energy for the future.

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 require protection from the wind, rain, etc. They are normally placed between glass to protect them. These cells are connected inside the module in a series pattern. A series means that the circuitry is connected in such a way that the current will pass through all of it.

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.

The energy is then processed by an electricity grid and then an inverter in order to make the best use of it. Batteries can be used to store any extra energy that is not used at that time if the system is a stand-alone. There are many solar gadgets on the market that operate in this same fashion.

Financial incentives are available for individuals in many different countries to take advantage of the opportunity to support renewable energy efforts now. This is the time to convert your home or business to solar energy and help to change the future of the world. There is more renewable energy being wasted every day than can every be used, and natural resources are being depleted.
