Green Energy Source - Solar Power

In this world of energy, an energy source that is clean, quiet, extended indefinitely and is very important. Solar energy and solar energy is the energy that meets these criteria. The energy generated by solar panels and solar cells are the most valuable resource today. Solar energy use was widespread in antiquity, but modern civilization emission energy and solar power generation solar power for use in many ways has become a very useful concept and process.

Converts solar energy into electricity. Photovoltaic systems use sunlight to electrical installations. A solar cell is primarily composed of two or more thin layers of semiconductor material. Materials are usually silicon. The plates are exposed to light and electrical charges are generated. These costs will be directly converted to DC. This equipment generates solar electricity without emitting greenhouse gases, s, and the operation is almost silent.


When the system is unable to deliver electricity to power buy back the network. Here the main network acting as an energy storage system power, and therefore the system does not require battery storage. Such systems are generally connected network integrated into buildings without noise and solar energy. This can be incorporated into buildings in various ways.


There are several cell types in the market. Monocrystalline silicon cells are the most common of them. The main advantage of this cell type is normally a high efficiency is 15%. Polycrystalline silicon cells are also widespread. These are cheaper to produce, but the average efficiency is 12%. Amorphous silicon cells are also useful because they absorb light more efficiently than crystalline silicon. But these cells are less efficient than crystalline based cells. Even though the cost makes them ideal for many applications where efficiency is not a problem.


The most important aspect of solar energy is renewable and environmentally friendly. In today's world, limited resources and pollution, where there are big problems, solar energy and solar power to solve problems very effectively.
