Solar Cell Uses

Isaac Said:

can solar cell be used for power supply for a big city ?

We Answered:

Yes, they could, if you had enough of them, and the sun was shinning, brightly, not during the night.

There are already existing solar cell "farms' where many kilo-watts of electricity are being produced in the South Wes desertt, and power is transmitted to large city near them (sorry, don't know which, now).

Problem is the initial investment, they are one of the more costly alternative energy systems. But, costs have gone down in recent years.

Windpower may be a better alternative as large windmills could be installed a the top of many large buildings.
Windpower generators could be used in conjunction with an existing cell-phone tower, or infrared signal transmission tower, not sure if anyone has investigated that.

Windpower can work, day or night, doubling the efficiency of them, getting more watts of power, for buck invested.

Fred Said:

why is a solar cell used in tv stations?

We Answered:

You really need to clarify this question! Solar cell use with respect to what at TV stations?

I don't know if you are talking about some remote, solar powered, relay station ... or the TV station accountant's solar powered calculator?

Please be more specific or I can't help you.
