Product Introduction

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.

  • LumiSolarOutdoor Battery-Powered
  • LumiSolarOutdoor Line-Powered

The line powered version is designed to measure strings of modules. The modules are biased by a remotely operated power supply. For this purpose an electric three-phase power is required. The line powered version is designed for high throughput operation.
