Solar Energy

This technique is best used under the implementation of unit solar radiation (solar unit) without optical lenses or concentrates, so it can be fixed on the rooftops to benefit from it in electricity production. Its estimated efficiency is about 20% and the rest is used to profit from saving heat for warming and heating water. The solar cells are used as well in operating the system of different telecommunications, in lighting the roads and facilities, in pumping water, and others.
