Love doesn’t make the world go around. The sun does.

Almost all the renewable energy sources originates entirely from sun.

The sun, with its by-products (wind, water, biomass, waves) supplies our planet with 15,000 times more energy per day than humans consume.

Two search requests on the internet website Google produce "as much carbon dioxide as boiling a kettle", according to a Harvard University academic.

A typical search returned a result in less than 0.2 seconds and that the search itself only used its servers for a few thousandths of a second. This amounted to 0.0003 kWh of energy per search - equivalent to 0.2g of CO2.

Going Green @ Google

In June 2007 Google completed a 1.6MW solar installation at Mountain View, CA headquarter. This installation produces enough electricity to power 30% of Google's peak electricity demand in solar powered buildings at our Mountain View, CA headquarters.

Solar energy versus other green energy

The relative economics of Solar Energy verses other Renewable Energy sources will depend on country or regional specific factors. Solar Energy economics are at their best in Regions with high solar radiation factors.

Solar Energy comes in to its own through its freedom to choose the site of energy production and its ability to directly match individual (residential or commercial) customer loads.

Solar requires valuable raw materials, whose scarcity can often increase costs.

Applications of Institutional Solar Photovoltaic

Remote area electrification.

Solar powered water pumps are very efficient and cost effective in agricultural application.

Highway directional signs can use PV system to save the expense of excavation to extend electrical lines to sign as well as cost of maintaining the electrical line.

Health care system

Telecommunications

Transport aids

Security system

Advantages of Solar PV system

Since the solar energy is free of cost hence no operating cost.

Solar energy systems are not location specific. Almost every place, sun radiation is available.

Electricity is the most convenient and most general form of energy which can be generated by using spv systems and can also be converted into other form of energy as per requirement.

Spv systems don't have any machinery(moving system) which results low maintenance and repairing.

Proven technology Only supporting systems like inverters, batteries require some maintenance.

Systems are very durable. Typically solar photovoltaic modules having life more than twenty years. Only some cleaning of upper surface of module may be done occasionally for proper working.

Disadvantage

Sophisticated technology, not suitable to local manufacture.

Balance of system components still under development.

High initial investment cost.

Low Efficiency

Skilled engineers needed for maintenance.

Output subject to solar insolation variations and weather.
