today

here are three reasons why solar energy generation has not

Developed.

Do you know what is that………………..?

Yes you right.

The first,the cost per watt of solar cell generation is more expensive than

That steam power or nuclear power generation.

Therefore,researchers are stiil loking for ways to make solar cells cheaper.

So…when they will find it………………….?

Yes I believe and sure you heve oppornity to find it.

The second is problem,nature plays a large part in solar cell generation.

I think you give exemple about the probem…….

What is that………………?

Yes I agree with your answer….

Some days are cloudly and rainy”because there is not always fine weather

So I think solar energy canot be granted everyday.no solar energy is

granted at night.

Consequently,solar cells must have the capacity to store energy for use during

these times,and these storage cells are very expensive.

As a result,only in low latitude areas can enough solar energy be granted

Effectively at these times.

Finally,building plants for solar cell generation is extremely expensive.

A very large space is need,and the need for maintenance is constant.

To ilustrate the surface of solar cell plant has cleaned daily.

For all these reasons,it is very difficult to develop solar cell plants

And make solar energy available to the general public for a competitife

Price

Despite all these problems,I believe the day will come whwen we use

Solar energy cells because they are form of clean energy with no polution.
