Gain an understanding of your own energy usage. Before converting to solar energy, it's vital that you have a good estimate of the amount of power that your home or business uses. In order to pick the right size, this information is critical. Look at your energy bills and invest in an energy monitor to keep track of how much power you use.
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.
Before installing solar panels on your roof, check with your home owners association. Some associations have restrictions on what you are allowed to do to the outside of the property, and this might mean solar panels are not an option for you. It is better to have this information up front than to purchase the panels and be forced to remove them at a later time.
