Open air measurements for direct, on-site inspection
The award-winning LumiSolarOutdoor system enables the investigation of 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, as damages due to transportation are prevented.
The battery-powered system enables measurement of single solar modules without the need of an external power supply, providing the greatest flexibility.
Successfully tested on various Solar Module types
