What are the recommended solar radiation sensor models and selection tips for the Solar PV industry?

In the performance assessment of solar PV plants, accurate irradiance data is crucial. Rika Sensor provides a complete suite of solutions ranging from individual sensors to system-level weather station setups.

• Core Recommended Model: RK200-03 Series Pyranometer

Utilizing the thermopile principle, this series covers a wide spectral range of 300-3000nm. It features excellent cosine response and long-term stability, perfectly meeting the requirements for measuring Global Horizontal Irradiance (GHI) and Plane of Array (POA) irradiance.

It is the preferred choice for large-scale utility projects and commercial rooftop installations seeking the weather sensors best in data reliability.

• System-Level Selection: RK900 Solar Environmental Monitoring Station

For in-depth power generation efficiency analysis, a radiometer alone is insufficient. We recommend the RK900 system, which integrates solar radiation, wind speed/direction, ambient temperature/humidity, and Back-Panel Temperature Sensors.

For premium projects requiring compliance with ISO 9060 Class A, we offer models with faster response times and lower zero-offsets. This environmental sensor series supports standard RS485 (Modbus-RTU) output, allowing direct connection to inverters, data loggers, or SCADA systems for lossless data transmission.
