3. Benefits of Solar Electricity (PV)
 Energy Independence
 “Fuel” is delivered free everywhere
 Minimal maintenance
 Maximum reliability
 Portability and mobility
 Reduce Vulnerability to power loss
 Systems are easily expanded (modularity)

Water heating and cooking Electricity production
Solar Thermal Solar Photovoltaic (PV)

8. Photovoltaic (PV) systems converts light
energy directly into electricity, commonly
known as “solar cells.”
The simplest systems power the small
calculators we use every day.
More complicated systems will provide a
large portion of the electricity in the near
future.
PV’s are not contributing to global warming
and pollution.

22.  A System that combines various energy
sources such as solar, wind etc is
called as “Hybrid” system.
 Diesel Generators are often used for
reliable power, solar are used to
decrease fuel costs.
 Optional combination of solar and
diesel to power at lowest overall annual
cost.
