Solar World Inc is a company that was founded in 2004. As a supplier, we only sell products specifically for Solar Panels. Marketing our company has reached Europe, Asia, Australia, Africa.Some products have a factory in the US.About Solar Panels.A photovoltaic (PV) module or solar electric panel is the smallest replaceable unit in a PV array. The module is an integral unit that provides support for a number of PV cells connected electrically and protected from the elements. The electrical output of the module depends on the size and number of cells, their electrical interconnection, and, of course, on the environmental conditions to which the module is exposed. Solar electric panels come in all shapes and sizes, and may be made from different materials. However,the most commonly used module is a ?glass-plate-sandwich? that has 36 PV cells connected in series to produce enough voltage to charge a 12 volt battery. The purpose of the structure is to provide a rigid package and protect the inter-cell connections from the environment. Plus (+) and minus (-) connectors are located on the back of the module for interconnection. The modules may have an individual metal frame or be protected by a rubber gasket and intended for installation in a larger mounting system designed to hold several modules.Did you know?MPPT type of solar charge controllers are especially designed to ensure your solar panel operates at the maximum power point. Using this type of solar charge controller can increases charging efficiency by as much as 30%.There are four factors that determine any solar electric panel?s output: efficiency of the photovoltaic cells, the load resistance, solar irradiance, and cell temperature. The solar cell efficiency is set by the manufacturing process; today?s commercially available modules are from 3% to 17% efficient at converting the solar energy to electrical energy.
