Patent ID: 7742897

Claim:
A computer processor implemented method of measuring, monitoring, comparing and diagnosing the power generated of at least two renewable power systems provided to a consumer, said method comprising the steps of; providing at least two renewable power systems, at least one data server, at least one generation monitoring device in communication with at least one said renewable power system and at least one communication node in communication with at least one of said renewable power system, said generation monitoring device and said data server, determining at least one diagnostic variable for each said renewable power system and saving each said at least one diagnostic variable into said at least one data server; determining at least one system coefficient for each said renewable power system and saving each said at least one system coefficient in said at least one data server; determining the energy generated by each said renewable power system and saving said energy generated in said at least one data server; wherein said at least one data server determines comparative information based upon at least one of a background constant, said diagnostic variable, said system coefficient and said energy generated to determine a comparative value of said renewable power system; wherein said comparative information is a geographic average and wherein said geographic average is determined by: randomly selecting a predetermined number of renewable power systems; determining the normalized performance of each said renewable power systems, summing said normalized performances to provide a sum and dividing said sum by said predetermined number to provide a geographic average; and saving said geographic average in said data server.
