Portable measuring device “Photon-3” is intended for measurement photo-technical parameters of solar cells and photovoltaic modules having peak electrical power up to 200 Watt in standard stationary illumination conditions (AM1.5, natural or artificial sunlight). It is developed for use in the Centre for solar cell and photovoltaic panel testing of the V.E. Lashkarev ISP NAS of Ukraine.
Area of application - terrestrial and space photovoltaic power engineering.
Created in the V.E. Lashkarev ISP NAS of Ukraine, measuring device „Photon-3” has no analogues in Ukraine. Patent protection of novel technical and technological solutions created during the device development is under consideration.
