Photovoltaic or PV technology employs solar cells or solar photovoltaic arrays to convert energy from the sun into electricity. Solar cells produce direct current electricity from the sun’s rays, which can be used to power equipment or to recharge batteries. Many pocket calculators incorporate a single solar cell, but for larger applications, cells are generally grouped together to form PV modules that are in turn arranged in solar arrays. There are several types of PV modules but According to the climate and geographical location of Pakistan most common and efficient solar cells are Mono-Crystalline solar cells and Poly-Crystalline solar cells.
