Hello,
  I am new to the Solar Energy, apart from what I had learned in high
school, therefore looking for your help in building the solar power
system for my rice factory.

I have a rice factory that requires 100KW for its running. I am
thinking of using the solar power to obtain the 100KW requirement.

Could someone kindly provide me the average cost of bulding a solar
panel system that will fulfill the requirment of my factory.

I have heard the hardware would be cheper for me to purchase from China
and Japan, as I live in Asia. Pleases suggest compaines from where I
can purchase the hardware and any other information on how to build the
solar power energy system.

Thank you

Imran

Depending in how much sunlight you get, and how much of the day your
factory runs, the availability of a grid for backup, and other
factors, installed solar electric systems cost between $ and $0
(USD) per watt.  If your factory needs to run 24 hours a day, you are
going to need at least 5X that in installed panels.  So, given the
information provided, somewhere between 1/2 and 5 million dollars US.

I'll add that there are also the options of using wind power. And yes,
PV panels and equipment built in the far east are less expensive.

Another factor is the payoff time of using the alternative power
system; you need to factor in maintaining the system, designing the
system. What if a Typhoon hits and destroys part of the system? What if
part of the system fails? There are a lot of factors involved in a
system that have to be looked at before you start.

Many people in this group start small; say powering one room or one
device as a hoot. Then they start expanding what they are doing and
before you know it, there's some serious money tied up in the deal and
now you've got to become an expert. From what I've seen, going right
into 100% alternative energy is expensive and almost always so
expensive that you may not realize a true return on the investment.

Oh come on, I suspect Imran's power requirements are
mostly thermal in nature. It would be INSANE to use
expensive solar PV panels to produce low cost heat.

A much better use of money is to use solar "thermal"
systems.

Depending on the temperature requirements, solar
thermal panels are much lower. If higher temperatures
are required solar troughs or dishes perform well
and at a cost in $/W 10 to as much as 25 times lower
in cost per watt.

Ok, I would suggest using solar tracking techniques
to reduce costs even more.
