Requirements for solar cells in photovoltaic power system

The solar cells are solar panels, also called solar photovoltaic . It is composed of a plurality of single solar cell according to the requirements of power and voltage in series or parallel combination together, and then through a special production process for packing. It is one of the most important components of solar photovoltaic system , must meet certain requirements.

First, solar cells from factory production to transport ,install and use, it will be experienced a series of shock and vibration external force, especially after installation should also be able to withstand the impact of hail. Therefore, it is necessary to have sufficient mechanical strength. Solar cells glasses must be tempered , and pass a fall experiment to test.

Secondly, after installing solar battery generator to more than 20 years of time , They constantly generate an electric current, experience all kinds of weather conditions, to prevent cell subjected to corrosion. Therefore, the component must has good sealing and insulating property, to windproof, waterproof, anti leakage.

In addition to the cell level of good or bad, the most important is product workmanship, the quality of workmanship has a direct impact on service life of solar battery component. So when purchase solar battery components, be sure to pay much attention to product workmanship . Before installation , you must pre-sort solar battery assembly, as far as possible combine the similar voltage or current of components in a square array to achieve the best effect. 

For planning to install solar photovoltaic users, they have to consider: Is your roof suitable for installing solar power generator system?? because it is directly related to the actual using effect. If not, you can consider the easy carry and best price of portable solar generator . Want to know more information, please visit http://www/poweroak.solar.com/
