Solar Resource Assessment Using Micro-Inverter Data: Preprint
- National Renewable Energy Laboratory (NREL), Golden, CO (United States)
The AC production data from Enphase Energy Inc. micro-inverters for 100 locations in five metropolitan areas were used to derive the location's direct normal irradiance and diffuse horizontal irradiance resource. These data were then used to model the energy production of nearby photovoltaic (PV) systems. Results had small bias errors, and for most locations the results were significantly better than when using satellite-based National Solar Radiation Data Base irradiance data to model PV system energy production. Using performance data from some of the millions of installed PV modules with micro-inverters offers the opportunity to provide ground-based solar resource data critical for developing PV projects and for the site adjustments of satellite-based irradiance data.
