Abstract
Solar cells being highly sensitive to temperature, I-V characteristics of the cell get adversely affected with temperature rise. Solar insolation heats up the panel which may lead to the decrease in efficiency. For longer life of cells, waste heat produced has to be discarded. Hybrid photovoltaic solar thermal system consists of photovoltaic modules and thermal collector. Placing thermal collector at back side of panel helps in waste heat extraction (water/air/any substance can be used as fluid medium). If the fluid medium is water, it can be given to desalination unit which in turn helps to improve the solar still performance. The main problem solar still facing is its lower productivity. Feeding the preheated water from PV/T system is a feasible solution. This in turn improves system efficiency. This paper discusses a simple design of desalination unit coupled with photovoltaic thermal system and ways and means to improve the performance of desalination unit.
