The amount of electricity you generate from solar panels is dependent on how many panels you install and the efficiency of these panels. You will need to do a little math to calculate the number of panels you will need. Higher-efficiency panels are often your best bet cost-wise.
Know that solar panels do not immediately mean free energy forever. You need to be mindful of the fact that solar installations often carry a large up-front price tag. However, you also need to balance that with how much energy you can save over the long run, government incentives and the possibility of selling your excess power into the grid.

Solar panels are not very easy to install, so you should hire a professional to get the job done. While you will save a bit of money by trying to do it in your own, you do not want things to be less than perfect. Also, you will most likely end up paying someone to come out and fix the mess you made.
Never walk on solar panels. They are fragile and can cost you a lot of money if you break them. If you have to walk on them, don't walk on the ends since these are the most fragile areas.
