The SPN1 Sunshine Pyranometer is a meteorological class solar radiation measurement instrument with a built-in heater, and is designed for long-term outdoor exposure. It is an affordable and effective alternative to shade-ring pyranometers, pyrheliometers and traditional sunshine recorders. The SPN1 Sunshine Pyranometer is exceptionally easy to use; it needs no routine adjustment or polar alignment and works at any latitude.
The SPN1 Sunshine Pyranometer is protected by patents EP 1012633 and US 6417500.
An internal heater keeps the pyranometer dome clear of dew, ice and snow down to -20C (in still air conditions), ensuring reliable readings in difficult climatic conditions.
Recommended for financeable resource assessment campaigns, the Hukseflux LP02 is a solar radiation sensor that is compliant with second class criteria from the ISO 9060 standard.
This thermopile-based sensor measures global horizontal irradiance and has a spectrally flat response across the full solar spectrum. The LP02 generates a small voltage signal that is proportional to the solar radiation flux, expressed in W/m2.
The LP02 is compatible with theSymphoniePLUS3 Data LoggerandSymphoniePRO Data Loggerwhen equipped with aSymphonie SCM Card(SCM #6646, used with SymphoniePLUS3 or older) or Pro Signal Conditioning Module (P-SCM #9128, used with SymphoniePRO).
This kit includes a calibration certificate and 5 m (16.4') cable.

The LI-200R measures Global Horizontal Irradiance (GHI) - the combination of Direct Normal Irradiance (DNI) and Diffuse horizontal irradiance (DHI). The sensing element measures sunlight in watts per square meter (W/m2) and provides a small current signal that is compatible with any Symphonie series data logger when equipped with a Symphonie SCM Card.
The LI-200R is an improved version of the popular Li-Cor LI-200SZ Pyranometer. The new sensor has several advantages:
This kit includes a calibration certificate, leveling base, and 2 m (6.6') cable.
Quantify the site-specific impacts of soiling on prospective and current PV projects with NRG's Soiling Measurement Kit.
NRGs Soiling Measurement Kit provides users with the information needed to quantify the site-specific impactsof soiling caused by snow, dust, and other particles on prospective and current PV projects. These data are usedto improve pre-construction annual energy production (AEP) estimates as well as maintenance schedules (i.e., panel washing) and forecast models in the post-construction setting.
The Soiling Measurement Kit interfaces with theSymphoniePRO Data Loggervia its interface module, which provides four 0 V to 5 V (analog) signal outputs:
The interface module requires a single 12 V excitation (EXC) and ground connection (GND) available from any combination of built-in logger channels (16-19) and P-SCM channels (20-26). P-SCM channels require P-SCM item 9132.
Determine site-specific soiling loss characteristics with this turnkey soiling measurement solution.Install easily as an accessory to NRGsSRA System complete with PV modules, pre-installed back-of-moduletemperature sensors, flexible mounting hardware, and integrated soiling interface module.Measure short circuit current and back-of-module temperature with users choice of statistical interval as wellas optional 1 Hz sample data collection for flexible analysis options to meet data demands.
