Solar energy / PV monitoring

Hukseflux is a leading manufacturer, both in technology and market share, of sensors for solar radiation measurement. The purpose of solar radiation measurement in photovoltaic (PV) systems is to compare the available resource to the system output and to determine efficiency. The efficiency estimate serves as an indication of overall system performance and stability. It also serves as a reference for remote diagnostics and need for servicing.
Our product range for PV monitoring includes pyranometers (measuring global solar radiation) and pyrheliometers (measuring direct solar radiation). We supply to the world's largest PV system performance monitoring companies, system integrators and OEM customers. All our solar irradiance sensors comply with the relevant ISO, WMO and IEC standards.
The comprehensive new IEC 61724-1:2017 standard for PV system performance monitoring is explained here.
