Abstract :
Temperature rising is a negative factor in almost all systems. It could cause by self heating or ambient temperature. In solar photovoltaic cells this temperature rising affects on the behavior of cells. In reality, it affects on components of equivalent circuit. This paper tries to analyze temperature effect using binary coding method and introduces a manner to reduce temperature negative effect on solar cells at shadow condition. MATLAB software has been used for simulation. Results show that more parallel bypass diodes could reduce thermal effect at partial shading and produce more power. Additionally, it could prevent early ageing of photovoltaic panels.
