Effect of tilt angle of PV module

The performance of PV module depends on amount of solar radiation received by a PV module which in turn depends on the orientation and tilt angle. The orientation of modules is generally south in northern hemisphere and north in southern hemisphere. The tilt angle is site dependent and has to be optimized to maximize the incident solar radiation on the surface of PV module. Yadav and Chandel have reviewed various computational methods to determine tilt angle of PV module using different optimization techniques. Thus, in order to increase the energy output of a solar system, PV module should be inclined at optimum orientation and tilt angle determined for the site.
