Sunmeter - Model PRO -Photovoltaic Pyranometer
Sunmeter PRO is a digital photovoltaic pyranometer (or silicon irradiance sensor) for calculating photovoltaic plant performance with a high degree of precision and reliability. Its monocrystalline silicon cell is laminated with glass for photovoltaic modules and E.V.A. like a micro PV module. It has additional stabilization processes and tests to minimize measurement drift over time. The cost includes a recalibration service after one year as well as the immediate replacement of the irradiance sensor if tolerance exceeds 3.5%.
Sunmeter Pro – Accurate, Reliable Photovoltaic Pyranometer
The Sunmeter PRO is easy to install and use. Compared to the Class A thermopile pyranometer, it provides a more adequate measure for the calculation of the P.R..
Every Solarimeter cell has been calibrated by a stabilized PV reference cell at the Dakks accredited ISFH.
This irradiance sensor is available in two models:
- the “complete model” which provides for Analog and Digital output.
- the 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.
