Many Uses Of Solar Energy
Residential
The number of PV installations on buildings connected to the electricity
grid has grown in recent years. Government subsidy programs (particularly
in Germany and Japan) and green pricing policies of utilities or electricity
service providers have stimulated demand. Demand is also driven by the
desire of individuals or companies to obtain their electricity from a clean,
non-polluting, renewable source. These consumers are usually willing to pay
only a small premium for renewable energy. Increasingly, the incentive is an
attractive financial return on the investment through the sale of solar
electricity at premium feed-in tariff rates.
In solar systems connected to the electricity grid, the PV system supplies
electricity to the building, and any daytime excess may be exported to the
grid. Batteries are not required because the grid supplies any extra
demand. However, to be independent of the grid supply, battery storage is
needed to provide power at
