Solar Radiation Sensor Soz

The SOZ-03 pyranometer consists of a mono-crystalline silicon cell (50 x 50 mm ²) with special solar glass. The pyranometer is laminated, hence high UV-resistance and long-term stability. Engineered for accuracy and reliability, this sensor delivers consistent readings under various environmental conditions, including high temperatures and humidity. Its compact and robust construction allows easy installation on solar PV plants, meteorological stations, and research setups. With seamless compatibility with IoT and SCADA platforms, the SOZ-03 ensures real-time monitoring, optimal performance assessment, and data-driven decision-making for solar energy projects.
