Solar Photovoltaic Technology

When everybody is looking at nuclear energy here is someone who looks at Solar Photovoltaic technology to satiate our energy demands. The estimated solar energy radiation falling over India is about 5000 trillion kWh a year which is enough to provide us 90kWh per capita, even if 1 % of the 5000 trillion kWh is harvested fruitfully. This technology looks at large the best technology to invest for our future energy demands considering the fact that there will always be a never ending supply of solar radiation which is highly unlikely in oil or even in nuclear energy.

As per the December 2005 records, there are already 13 lakh SPV systems with an aggregate capacity of 245 MW which is functioning in our country.

The flip side of this technolgy is the common silicon based SPV panels which are not only costly, it also has a conversion efficiency of only 10 %. In other words it needs 100 watts of electricity to create just 10 watts of SPV capacity. Added to it is that there is a acute shortage of pure silicon.

Ofcourse no one can discount the belief that these problems can be pretty much solved by determined research.

Cool one Monoj, but the 10% conversion is advantage rather than disadvantage. cos the 10% conversion is good. we can further improve it da..
