Abstract: A method for installing a renewable energy power generation system at a selected site, having a first database with a first group of installed power generating systems; a second database with a second group of power generating systems selected from the first group based on a location match to predetermined location parameters; a third database with a third group of power generating systems selected from the second group based on correlation match to predetermined correlation parameters; a fourth database storing operational data from the third group characterizing the power generating systems, and a fifth database with various types of power generating systems; a power generation system is selected from the fifth database that is capable of producing the averaged normalized potential power generation at the geographic proximity of the selected site. Finally the selected power generation system is installed at the selected site.
