The whole point is a money saver while providing light. Right now we pay a lot for electricity, and in about a couple months, that's going up fifty percent. So to counter this, we are trying to use alternative energy sources. In the near future, we are planning to put up a windmill to help with house electricity. But, the reason I went solar is so I wouldn't have to use the house electricity. And also, so i could get some experience designing, and setting up systems like this. What size solar panel would you recommend? Eventually, we are planning to be totally independent from the grid. But, due to money issues, we can't rush into it. So one thing after another. I also don't think this is going to be cheap.
