It is not possible to predict the average saving by using solar powered fans because the savings would depend on the size of your house. To calculate your savings, you can use a solar power calculator at findsolar.com.
It will take years for everybody to have solar power, because of the cost of the solar panels and such, but I would say that it would take at the most probably 50 years.
Solar power only requires initial investment. The cost of setting up solar panels is high, but after that, the cost of maintenance is negligible.
As an average, the solar cell price of 1 Sq. Ft. of solar panel in India comes to around Rs. 4,500. This is sufficient to generate solar power of 10.6 Watts. So, when is about powering home appliances like Television and Refrigerator you would have to install around 60 solar panels.

The cost of your solar system is directly related to how many kilowatts your home uses each month. That is what determines how much power you wish to generate.
Irrelevant, solar power is completely useless
solar power from a concentrated solar power plant costs the same as electric from a fossil fuel pant. if you install home photovoltaic solar panels, it will cost up to $25,000. after installation, there is little maintenance and the panels will last over 30 years.
There is no general easy answer to how many panels are needed for your exact home. This depends on how much power you use, how much rainfall you receive in your location, and other factors. A solar panel can create 70 milliwatts of power per square inch, so completely changing an average home's power usage to solar would require a solar panel that measures about 285 square feet, or about 26 square meters. This would cost around $16000. Without decreasing your lifestyle's dependency on electricity, powering your home exclusively through solar power is difficult.
15 Hp cost
The average solar panel cost about $3.00 a watt wholesale. It delivers about $0.0015 per day. The projected life is about 20 years if the weather is not too hot.
