Abstract:
1. An insolation sensor for determining a solar light intensity as a basis for evaluating electric power generated by solar modules exposed to the solar light intensity, the insolation sensor comprising: an outer surface including a light entrance window; at least one photo sensor configured to measure the solar light intensity, wherein the at least one photo sensor is arranged behind the light entrance window; and a detector device configured to detect precipitation and/or a resulting deposit on the outer surface, wherein the detector device further comprises a plurality of photo sensors configured to determine a spectral distribution of light received at at least one surface selected from the outer surface and a comparison surface arranged in parallel to and laterally beside the outer surface, and wherein the detector device is configured to detect precipitation and/or a resulting deposit on the outer surface in response thereto.
