How it works
MS-80SH Plus +
Solar Monitoring Station
Class A monitoring solution for Diffuse Horizontal Irradiance measurements
The MS-80SH Plus + is the all-in-one solution built on MS-80SH fast response Class A pyranometer with rotating shadow band to measure GHI, DHI and DNI solar irradiance. The autonomous system is reliable, accurate, cost-saving alternative to larger sun tracker-based options.
MS-80SH Plus +
The MS-80SH Plus+ is a trackerless solar monitoring station. Built around the unique internal rotating shadow band design of the MS-80SH Class A pyranometer. The MS-80SH Plus + adds the industry and ISO 9060:2018 class-leading MS-80SH Class A Pyranometer with integrated dome heating patented technology, and an original C-Box smart interface, for complete GHI, DHI, and calculated DNI measurements.
A practical solution to the increasing diversity of solar power plant locations and Photovoltaic (PV) applications, the MS-80SH Plus + can easily be deployed. This solution can provide a major benefit in terms of compliance with the updated IEC 61724-1 guidelines, as carrying out both GHI and DHI measurements is a criteria to fulfill the standard best practices when monitoring bifacial photovoltaic modules.
