PV modules can be used in PV system for generating electricity. PV modules are available in range of power ratings that vary from few watts to hundred watts. Also, these modules are made from different types of materials. Various parameters of a solar PV module include Short Circuit Current (ISC), Open Circuit Voltage (Voc), Fill Factor (FF), Efficiency (η), Peak Power (Pm), Series Resistance (Rs) and Shunt Resistance (RSh). Factor affecting electricity generated by a solar cell Sun intensity,

Losses in solar cell loss of low energy photons, loss due to excess energy of photon, voltage loss, fill factor loss, loss by reflection, loss due to incomplete absorption, loss due to metal coverage & recombination losses. Tracking concentrator uses proper tracker hardware. No additional mirror supporting structures are needed. It could increase solar power efficiency of PV panels. Substantially reduce unit price of PV power in presented. The efficiency is increased due to low cost tracking system. Flat plate solar PV module when placed in the field shows increase in temperature. This increase in temperature is due to the loss of heat that is unutilized in energy conversion. The temperature rise is due to unutilized energy, which mostly comes from the high-energy photons. To operate solar cells at high concentration levels, one has to use proper cooling techniques. These may range from passive convective cooling, using heat sink, or active convective cooling, using flowing water.
