Technical Issues in Grid Connected Solar Photovoltaic Roof Top system: A Review

The worldwide depletion of fossil-fuel resources has necessitated an immediate search for renewable energy sources to satisfy tomorrow's demand. Present expectations for renewable portfolios are modifying power systems by replacing conventional generation with clean energy options such as photovoltaic (PV) systems. Solar energy is a clean, inexhaustible and environmentally sustainable fuel among all green energy choices.For the sustainable growth of electric power, the use of green energy systems such as SPV power plants offers reliable power throughout the day.If the SPV power plant is installed into an interactive grid system, the power during non-solar time is imported from the grid and the surplus energy during solar time is fed into the grid.As a result, in order to meet load demand, grid-connected power system networks are now being deployed, integrating solar and utility grids, where the grid serves as an energy storage facility.In this review article the technical issues associated with grid integrated roof-top PV systems and current scenario of generation of solar power in India is discussed.
