Issues of solar power

• Hugh land requirement• Production of the solar cells carries an upfront

cost to the environment via production, but offers clean energy throughout the lifespan of the solar cell.

• Intermittent power generation & available in day time only

• Low efficiency & CUF• High capital cost & high Cost of electricity

Hybrid RE SystemsIn the future, several hybrid systems consisting of wind , solar, Biomass & small hydro installations could be connected in clusters to form micro grids which can support the functions of the smart grid by firming up variable generation.

These micro grids can be integrated to a larger power system or national grid. Some hybrid systems could be the combination of the following:PV/Battery, PV/Diesel, PV/Battery/Diesel,Wind/Battery; Wind/Diesel; Wind/Small Hydro; Wind/PV/Small Hydro; Wind/PV/Biomass.Small Hydro/Biomass; Small Hydro/Battery/Biomass;

Solar & Wind energy technologies are pollution free and

environment friendly and are compatible with smart grid.

Hybrid systems shall help in firming up the variations in

generation .

Wind energy has very good potential and it is the fastest

growing energy source

The future looks bright for RE technologies as smart grid

technology will make these installations viable and

attractive for generators as well as consumers.
