Principle Of Solar Panel

Most of us are now aware of increasing use of solar panels however it is high time to understand solar panels basic principles and solar power to have a better idea on how to go about solar panels installation at our homes shops schools colleges institutions and commercial ventures industries.

Principle of solar panel.

Solar panel working principle a photovoltaic cell is also called a solar cell. Solar cell any device that directly converts the energy of light into electrical energy through the photovoltaic effect. Solar cell multicrystalline silicon photovoltaic modules commonly called solar modules are the key components used to convert sunlight into electricity. Solar panels are in turn combined to form solar arrays.

They may or may not be backed by batteries. Since a solar cell only generates about 1 2 watts of power it is necessary to combine them into solar power panels in order to generate more power. Solar modules are made of semiconductors that are very similar to those used to create integrated circuits for electronic equipment. A standard solar panel also known as a solar module consists of a layer of silicon cells a metal frame a glass casing and various wiring to allow current to flow from the silicon cells silicon atomic 14 on the periodic table is a nonmetal with conductive properties that allow it to absorb and convert sunlight into electricity.

The other components of the system convert the. Solar panels basic principles. When light reaches the p n junction the light photons can easily enter in the junction through very thin p type layer the light energy in the form of photons supplies sufficient energy to the junction to create a number of electron hole pairs. It consists solar panel arrays storage batteries and inverter circuits.

An off grid solar power system is not connected to any electric grid. These solar panels and arrays are the key component of all residential solar energy systems. The solar cell technology is the fastest growing power generating technology in the world. How do solar panels work to generate electricity.

It is due to fact that the solar cells with conversion efficiency of more than 40 are becoming available. The majority of solar cells are fabricated from silicon with increasing efficiency and lowering cost as the materials range from amorphous to polycrystalline to crystalline silicon forms.
