Solar electric panels are the photo-voltaic systems that create electricity by capturing and depositing sun energy and convert it under the form of direct current. Most often, solar electrical panels are referred to as PV systems, which is the short for photo-voltaic.

The basic working element of such a system is the cell; a large number of interconnected cells are organized so as to create modules, which in their turn are responsible for the overall formation or unit. Solar electrical panels can be used for outdoor lighting systems, home applications as well as for covering the energy needs of entire households.

An overlooked advantage of solar electric panels is that they save you from the risk of blackouts. Such occurrences are pretty frequent in parts of the world more exposed to thunderstorm formation. Since solar electric panels send the accumulated energy to batteries on which the system operates, overcharging is not possible due to the presence of a controller that stops the process when the battery is full.

When you are generating more power than you can use, you can actually send it to the common utility net, for which you get paid. This means that home users sell the energy that they produce over the necessity limit of their household. This process is perfectly legal under the law. There is a limitation as to the number of solar electric panels that you can use on the house roof and normally you should not produce more than 200% of the house electricity needs.

The price of solar electrical panels increases with size. The larger the system, the more expensive it will be. For a two kilo-watt system the cost for complete installation would be between $16,000 and $ 20,000. Fortunately there are some rebates and tax credits for people who want to go solar. This means that you can save up to 30% on your tax bill if you install solar electrical panels.
