You will be installing Solar Energy at any point in the world. You need some preliminary information about this point. When you open the PV_Data program, if you touch (or click) the desired point on the map, you will get the solar data at this point graphically and numerically. The data (results) in question are the approximate cost of the system, annual and monthly electricity production, annual profit and amortization period. These results are instructive for any real person or a relevant engineer who is preparing to make a solar installation and are a pre-feasibility study for the project he will do.
