Silicon photodiode solar radiation meter / LPSILICONPYRA04

All-weather solar radiation meter using silicon photodiodes as sensors.

Using a silicon photodiode sensor with a measurement wavelength of 400 to 1100 nm, the total solar radiation (W/m²) is measured. A special surface shape design and diffuser achieve a 180° field of view in accordance with the cosine law. It can be used for measuring solar radiation in the field of renewable energy, such as solar thermal power and photovoltaic power generation. ■ Comes with a 5m lead cable as standard (with stripped ends), and the typical output is 20μV/(W/m²). ■ Custom cable lengths can be manufactured upon request at the time of order. ■ Additionally, by using a base with a level, the solarimeter can be installed horizontally. ▼ All-weather solarimeter with a silicon photodiode as the sensor ▼ Measurement wavelength of 400 to 1100 nm, measurement range of 0 to 1400 W/m² ▼ Typical sensitivity of 20μV/(W/m²), response time <1μs ▼ 180° field of view due to the upper surface shape and diffuser
