An economical silicon pyranometer for fast-response solar irradiance measurement in PV applications.
| Datasheet |
Product Description
The LPSILICON-PYRA04 Pyranometer is a low-cost solar radiation sensor designed for measuring global solar irradiance using a silicon photodiode.
It offers fast response and simple operation, making it ideal for applications such as solar PV monitoring, solar thermal systems, and general irradiance measurements. The sensor features a cosine-corrected diffuser with 180° field of view, ensuring reliable measurement under direct sunlight conditions.
As a photodiode-based sensor, it provides a more economical alternative to thermopile pyranometers, especially suited for clear-sky conditions and cost-sensitive applications. For higher accuracy in varying spectral conditions (e.g. cloudy skies), thermopile pyranometers are recommended.
