Sunmeter - Model Pro -Digital Photovoltaic Pyranometer
Sunmeter PRO Certified is a digital photovoltaic pyranometer (or silicon irradiance sensor) calibrated by Fraunhofer ISE(DAKKS accred.). A digital photovoltaic pyranometer (or solar irradiance sensor) for calculating photovoltaic plant performance with a high degree of precision and reliability. This digital photovoltaic pyranometer consist of a monocrystalline silicon cell which is laminated with a glass usually used for photovoltaic modules and E.V.A. Our Irradiance sensor has an additional stabilization processes and tests to minimize the measurement drift over time.
Sunmeter Pro Certified – Calibrated by Fraunhofer Institute
This irradiance sensor is calibrated by Fraunhofer Institute for Solar Energy Systems(DAKKS accred.) The cost of pyranometer sensor includes a re-calibration service after one year as well as an immediate replacement of the solar radiation sensor if tolerance level exceeds 3.5%. The Sunmeter PRO Certified is easy to install and use.
This irradiance sensor is available in digital output only model.
Note:the terms irradiance sensor, photovoltaic pyranometer, reference cell and solarimeter are interchangeable. On this site we will use photovoltaic pyranometer. To learn more click here.
