Solar Power
Solar power:
In fact, every minute, enough energy arrives at the Earth to meet our demands for a whole year - if only we could harness it properly.
The Delhi Metro came to a standstill yet again on Tuesday afternoon after services were suspended for two hours due to collapse of the Northern Power Grid for the second consecutive day, causing inconvenience to commuters.
As the power grid collapsed at around 1 pm, Delhi Metro trains stopped on tracks, some inside tunnels, due to no supply of power and passengers stuck in the trains were evacuated immediately.
Nine trains stopped inside tunnels after power failure but they were brought to the near-by stations and all passengers were evacuated.
The services, which were suspended a little after 1 pm, were restored around 3 pm with minimum frequency after partial restoration of supply from the Northern Grid.
As the grid failed, Delhi Metro officials closed down all stations and evacuated passengers from the premises with help from CISF personnel, who guard the installations.
The most common DC voltages are 600 V and 750 V for trams and metros
The power output is supplied by 25-kilovolt, 50 Hertz alternating current through overhead catenary.
(Approximately 150 KV will be required by 2016 covering 140 km line.)
Delhi Metro, which consumes nearly 3 million megawatts of electricity per day, has managed to maintain the power charges per commuter at an average of Rs 1.12 over the years.
As the Delhi Metro covers more ground, more and more people have shifted to this mode of transport. Some 200 trains cover 70,000 km everyday on 190-km-long Metro corridors in Delhi.

The cost of solar panel 0.6$/watt. It will produce 1 mln watts per
