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)

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.

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.
