Methods for location identification of renewable energy systems

A computer processor implemented method of identifying the location of a solar irradiance sensor, said method comprising the steps of;

• providing a location-unknown solar irradiance sensor having solar irradiance sensor data in a computer processor;
• storing the solar irradiance sensor data in a computer processor;
• filtering said solar irradiance sensor data day by day for favorable weather conditions by a computer processor to provide filtered solar irradiance sensor data for each filtered day;
• identifying and saving the start of production, peak of production and end of production for each filtered day in a computer processor;
• calculating solar noon for each filtered day by a computer processor;
• calculating longitude bias for each filtered day by a computer processor according to an equation of time and the peak of production;
• calculating skew of observation by a computer processor according to the start of production, peak of production and end of production for each filtered day;
• calculating longitude for one location-unknown solar irradiance sensor by a computer processor according to the longitude bias and skew of observation for each filtered day;
• setting said longitude for the location-unknown renewable energy system to become a location-known renewable energy system that becomes part of a set of location-known renewable energy systems.
