Photo Voltaic panels create totally free electricity from the sun by converting daylight to electrical power with no shifting parts, zero emissions, and no maintenance. The photo voltaic panel, the very first component of a Solar Electrical Power System, is a assortment of individual silicon cells that create electrical power from sunlight. The photons (light particles) generate an electrical present as they strike the surface area of the skinny silicon wafers. A single solar cell makes only about 1/2 (.5) of a volt. However, a normal 12 volt panel about 25 inches by 54 inches will include 36 cells wired in series to produce about 17 volts peak output. If the photo voltaic panel can be configured for 24 volt output, there will be 72 cells so the two 12 volt teams of 36 each can be wired in series, usually 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) resulting in 75 to a hundred watts for a panel of this size.

Multiple solar panels can be wired in parallel to increase current capacity (more power) and wired in collection to enhance voltage for 24, 48, or even higher voltage systems. The advantage of making use of a greater 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 cost controller & batteries.

Monocrystalline solar panels: The most productive and expensive solar panels are made with Monocrystalline cells. These photo voltaic cells use really pure silicon and include a challenging crystal development process. Long silicon rods are developed which are cut into slices of .2 to .4 mm thick discs or wafers which are then processed into personal cells that are wired jointly in the photo voltaic panel.

Polycrystalline solar panels cost: Frequently called Multi-crystalline, photo voltaic panels manufactured with Polycrystalline cells are a small much less pricey & slightly less successful than Monocrystalline cells since the cells are not grown in solitary crystals but in a large block of many 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.
