Photo Voltaic panels produce free of charge electrical power from the sun by converting sunlight to electric power with no heading parts, zero emissions, and no maintenance. The photo voltaic panel, the very first part of a Solar Power System, is a collection of specific silicon cells that generate electric power from sunlight. The photons (light particles) produce an electrical current as they strike the surface of the skinny silicon wafers. A single solar cell generates only about 1/2 (.5) of a volt. However, a standard 12 volt panel about 25 inches by 54 inches will have 36 cells wired in sequence to produce about 17 volts peak output. If the solar panel can be configured for 24 volt output, there will be 72 cells so the two 12 volt groups of 36 each and every can be wired in series, typically with a jumper, enabling the photo voltaic panel to output 24 volts. When under load (charging batteries for example), this voltage drops to 12 to 14 volts (for a 12 volt configuration) ensuing in 75 to one hundred watts for a panel of this size. Multiple [http://solarpanels-cost.org.uk solar panels] can be wired in parallel to boost latest potential (more power) and wired in series to boost voltage for 24, 48, or even higher voltage systems. The benefit of using a larger voltage output at the solar panels is that smaller wire dimensions can be utilized to transfer the electric electricity from the photo voltaic panel array to the charge controller & batteries. Monocrystalline solar panels: The most successful and high-priced photo voltaic panels are created with Monocrystalline cells. These photo voltaic cells use quite pure silicon and include a difficult crystal expansion process. Prolonged silicon rods are developed which are reduce into slices of .2 to .4 mm thick discs or wafers which are then processed into personal cells that are wired with each other in the photo voltaic panel. Polycrystalline [http://solarpanels-cost.org.uk solar panels cost]: Frequently known as Multi-crystalline, solar panels created with Polycrystalline cells are a tiny less expensive & somewhat less effective than Monocrystalline cells because the cells are not developed in one crystals but in a huge block of a lot of crystals. This is what offers them that striking shattered glass appearance. Like Monocrystalline cells, they are also then sliced into wafers to generate the personal cells that make up the solar panel.
