USE OF BY-PASS DIODE IN MAXIMUM POWER POINT TRACKING SYSTEM

The shading due to clouds, buildings, tree ’ s etc. may affect the performance of photovoltaic array. Including this variation in temperature, solar separation is some more factors which affect the performance. The complete or partial shadowing of PV array tremendously affects its performance. In case of large PV array systems installed for distributed power generation schemes, the situation may get more complex under partially shaded condition. The multiple peaks generated due to shadowing affect may make PV characteristics more complex.
