MBMet-700 – Soiling Monitoring Station
IEC 61000-4-8
(Power Frequency Magnetic Field Immunity Test)
IEC 61000-4-18
(Damped Oscillatory Wave Immunity Test)
The MBMet-700 Series Soiling Monitoring Stations provide precise measurement of soiling-related losses on photovoltaic (PV) panels. By calculating key metrics like the Soiling Ratio and Soiling Loss Index, the system enables O&M teams to monitor loss in generation due to dust, pollution, and particulate accumulation—factors that directly affect energy yield and efficiency.
Designed for Utility and Rooftop Installations
Whether deployed in utility-scale solar farms or rooftop PV projects, the MBMet-700 system supports both environments with flexible mounting, robust components, and scalable...
