Photovoltaic technology has emerged as one of the methods of accessing energy for low level consumption. The systems use solar energy for generation of electricity. Since solar energy is available everywhere, this technology should serve as a great booster for rural electrification. There is no fuel cost or moving parts in this system, resulting in quiet functioning leading to durability and a soundless environment. Since 1980, a number of organizations in Bangladesh have been involved in research, development and diffusion of PV systems, but penetration among the users has been very slow.
