One of the main usages of solar energy that have had a noticeable development is direct production of electricity by using some screen that named photovoltaic. In these method photons or the high energy particles that coming from the sun caused releasing negative charge in the orbit by electron to make connection with hole (positive charge) and produce electric power by collision with semiconductor layers. Energy House company is the sale agent of LG Company’s solar panel that represent it’s solar panel productions as two types of mono-crystal and poly-crystal based on 240, 260 volumes.
