When exposed to light a Solar Electric Panel, or PV panel is a set of treated silicon cells arranged in a series string that produces electric power. The three common types of Solar Electric Panels are Polycrystalline, Monocrystalline, and Amorphous. Polycrystalline is the most common type which casts blocks of silicon that contains many small crystals. Monocrystalline are made from a single large crystal, and is also the most expensive.
Amorphous is the cheapest to produce, and is often much less efficient. For what it’s worth, all three work very similar, and they all do the same thing which is produce electricity from the sun. The great thing about Solar Electric Panels is that they come in all shapes and sizes, and may be made from different materials. It is the smallest replaceable unit in a PV array, which is an integral unit that provides support for a number of PV cells connected electrically. Efficiency of the photovoltaic cells, the load resistance, solar irradiance, and cell temperature are the major factors that determine the Solar Electric Panels output.
These solar panels should be placed in the sunniest place and kept as cool as possible because as the Sun’s brightness increases the output voltage and power decreases as temperature increases. Unlike a solar thermal panel which can tolerate some shading, Solar Electric Panels are sensitive to shading. But since it is impossible to prevent occasional shading, the use of bypass diodes around series-connected modules is recommended. Mostly allSolar Electric Panels have this feature integrated right into the module itself. All Solar Electric Panels should have durable, sturdy connectors on the module. When buying one of these solar energy panels, be sure to look at the junction box and see if it is easy to make the connections.
A circuit breaker as part of a combiner box should be installed to isolate the PV array during maintenance. Circuit breakers are normally installed to isolate each load. Fuses are used to protect any current carrying conductor. For extra safety and to protect against bad storms, all metal in aSolar Electric Panels should be grounded. So now that you have the basic information that you need, go out and get your Solar Electric Panels and cut down on your energy bills.
