Easy ten points for a decent answer guys!!!

Conversion of solar to electricity remains only marginally cost effective, and requires use of storage batteries, with all their associated cost and maintanence. Use of solar to heat water is viable, but storage of the hot water requires appropriate tanks, and you still may need to pump the water to site of use. We are perhaps ten years away from commercial solar farms. The biggest problem there is that solar is converted into DC power, which is very hard to transport over distances. Converting it to AC has about a 40% efficiency, making it unrealistic for widespread use and transmission over long distances.
Having said all this, solar may be very useful for specific applications, such as a power source for a farmstead or station house, for a limited purpose motor (like on a bore) or for some lighting applications, and in remote locations, may actually be cost effective, even at todays costs.
