Brief introduction of Photovoltaic Cells Solar Panels

Photovoltaic Cells Solar Panels convert the solar radiation through the photoelectric effect or photochemical effect directly or indirectly into electrical energy by absorbing sunlight;  the main material for most solar panels is silicon, but the production cost is so great that it cannot be a large number of widely and commonly used. Compared with ordinary batteries and rechargeable batteries, solar cells belong to more energy saving green products.

Advantages of Photovoltaic Cells Solar Panels

1) Solar energy resources are inexhaustible; solar energy shine on the planet currently consumes is 6,000 times larger than humanity to. Spread on Earth and the solar widespread, there are only local illumination can use solar photovoltaic panels, unrestricted area, elevation and other factors.
2), Solar energy resources are available everywhere, the nearest power supply. Without long-distance walks, preventing long-distance power transmission lines formed off the loss, but also has a throttling transmission costs. This is also the use of solar photovoltaic panels supplied premise transmission inconvenient western planning.
3), Energy conversion process of Photovoltaic Cells Solar Panels generating electricity is brief, which is a direct transition from photons to electrons. There is no central process (thermal energy into mechanical energy, mechanical energy is converted to electromagnetic energy, etc.) and mechanical activity, there is no mechanical wear. Based on thermodynamic analysis, Photovoltaic Cells Solar Panels generation with high theoretical efficiency, up to 80%, technology has great potential to develop.
4), Photovoltaic Cells Solar Panels do not use the fuel itself, does not emit any greenhouse gases and other substances, including gas, polluting air and noise, the impact will not suffer an energy crisis or the formation of the fuel market, is the real green environmental protection, new renewable energy sources.
5), Photovoltaic Cells Solar Panels generate electricity without cooling water process, the device may be in the desolate desert without water. PV can also be conveniently associated with the construction material, the composition of the construction of photovoltaic power generation system integration, covering not demand alone can choke precious resource site.
6), Photovoltaic Cells Solar Panels generate electricity without mechanical transmission components, operation, and maintenance simple, reliable operation of the same. A PV system only has a solar cell module can generate electricity, coupled with automatic control technology widely used; it can be done simply on unattended, low maintenance costs.
7), Photovoltaic Cells Solar Panels generate electricity tasking reliable, the service life (over 30 years). Crystalline silicon solar battery life is up to 20 to 35 years. In the photovoltaic power generation system, the only rational design, modeling appropriate battery life can last up to 10 to 15 years.
8), Photovoltaic Cells Solar Panels have simple structure, small size, light weight, easy to transport and installations. PV systems establish a short cycle, electricity load capacity vary, convenient and sensitive, easily combined expansion.
