Choosing the size of your system is the next step. With a grid-tied system, size is less significant, due to the fact the grid supplies electric power whenever your photovoltaic (PV) system falls short. Solar power systems no more than a couple hundred watts have proven to be practical, however you can also set up solar panels that will be able to generate enough electrical energy for all your needs.
