Well as one who has played with solar, It does have its pluses and minuses.
My current setup to "Play" with:
This is 8, 230 watt panels. It is capable of 1840 watts. As setup, I will never see that much power from this system. But even in total overcast and rain, I can make 100 watts. Thats right, 100 watts from those 8 panels. Solar has its pluses and minuses.
And here is a why I have all this power: It is Tilapitopia 2.0 . I am using Airlift to move water between tanks and I am using the excess solar power to heat the water.
So far we are still tweaking our system, but it looks very promising.
