The award-winning LumiSolarOutdoor system enables to investigate the quality of solar modules on-site. Defects can be identified quickly. Modules don‘t need to be demounted from their substructure. Measurements can be performed directly in the solar park or at rooftop PV installation after twilight or during the night. In contrast to other systems the LumiSolar-Outdoor system does not require a dark box or enclosure. It is the first system capable of performing measurements in the open air, thus saving time and cost. Moreover damages due to transportation are prevented.

There are two versions of the LumiSolar-Outdoor system available. A battery powered equipment enables to measure single solar modules without the need of an external power supply, providing greatest flexibility. A complete string of solar modules can be measured in a stepwise procedure using the line-powered Lumi-SolarOutdoor system if an external power supply is accessible. The LumiSolarOutdoor Line-powered allows a higher inspection throughput.
 

  • Inspection under open air
  • high time and cost savings
  • no demounting of modules
  • for all common module types
  • single modules and strings
  • excellent image quality
