• Heterojunction with Intrinsic Thin Layer (HIT)
Battery-powered LumiSolarOutdoor System
The battery based version of the LumiSolarOutdoor system does not need any external power source. A powerful battery generates the electricity for both, camera and the solar
module being measured. It is possible to apply up to 100V and 7.5A to the module.
