Monitoring of PV soiling losses has become increasingly important for both operational PV power plants and pre-construction site surveys. Therefore dedicated soiling measurement stations are now being routinely deployed at many sites. Such stations typically compare the output of a “soiled” PV device with that of a “clean” device. While many stations measure only the short-circuit current of the soiled...
One of the most critical inputs to a photovoltaic (PV) energy model is the solar data set, which establishes the site's irradiance and weather variability. For long-term energy estimates, the solar data set is expected to represent the long-term climatological conditions on-site. While modeled solar data sets are available, the quality of these data vary by data source as well as regionally. The result...
