As we know that the world have recognized that the best alternative of fossil fuel is solar energy because it have many advantages and less side effects because of which the trend of PV has came in global market. The manufacturing of PV is increasing as according to latest report that its manufacturing is almost reaching 48 percent average per year since 2002 and it has turn out to be the world fastest growing energy technology. Rough approximation says that almost 90 percent of generating capacity is consisting of grid-tied electrical system. This type of installation can be ground mounted or it can be on roof tops or walls and it have a particular name called building integrated photovoltaic or for in short terms BIPV.
Photovoltaic is the field of technology which tells that how the application of solar cell is utilizing light and heat from the sun in the electricity form so that it can be used as an alternative to the electricity which is being formed from fossil fuel.
