The sun is a gigantic powerhouse. The amount of solar energy captured by the earth in the space of just a few days is enough to meet the world's entire primary energy requirements for a whole year.
Solar Photovoltaic (PV) technology consists of solar cells that can turn solar radiation into direct current electricity.
Advantages:

• None polluting - no noise, no harm & smell & emission
• High reliability - 25 years warranty, long lifespan - theoretically 100 years
• Hassle free - low maintenance, low running cost
• Unlimited natural source - sun
• Economical - 1 gram of silicon used in a standard PV silicon cell produces 3,300 watt of electricity over its life span
