When the highest data availability and measurement accuracy are key: Hukseflux SR25 pyranometer for measuring solar irradiance

When measuring solar irradiance professionally, high measurement accuracy and high data availability are key. Traditional high-end pyranometers, ventilated or not, do not offer both, due to dew and frost. Now Hukseflux has introduced SR25, the ISO 9060 secondary standard pyranometer with sapphire outer dome and internal heater. It offers the highest data availability, while maintaining its high measurement accuracy.

SolarEdge Technologies - Solar Inverters, Power Optimizers and PV Monitoring

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power conversion architecture to achieve superior solar power harvesting and best-in-class reliability. The fixed-voltage technology ensures the solar inverter is always working at its optimal input voltage over a wider range of string lengths and regardless of environmental conditions. A proprietary data monitoring receiver has been integrated into the inverter and aggregates the power optimizer performance data from each PV module. This data can be transmitted to the web and accessed via the SolarEdge Monitoring Portal for performance analysis, fault detection and troubleshooting of PV systems.
