In addition, the integrated compass and inclination sensor allow you to quickly measure and document roof and site orientation, pitch, and panel tilt while surveying, installing, or adjusting an installation.

Features

Measure solar irradiance, ambient and PV module temperature, array orientation and tilt angles
Make instantaneous measurements to determine the Watts per square meter solar irradiation, required by IEC 62446-1 standard
High contrast LCD with large numbers for easy readability in direct sunlight
High precision mono-crystalline solar sensor: Instantaneous irradiance measurements up to 1400 W/m2
Two options for temperature measurement: Use the built-in temperature sensor or the external suction mount temperature probe to measure ambient and panel temperature
Integrated compass: Measure and document rook or site orientation
Inclination sensor: Know roof and PV panel tilt when surveying, installing, or adjusting the installation

Photovoltaic system design and surveying
To find the expected production at a site, determine your solar resource while taking shading into account. The solar resource is measured in peak sun hours: the number of hours per day with 1000 W generated per square meter of solar array. Location, time of day, season, and weather conditions all influence peak sun hours. Use this meter to determine the actual solar irradiance (Watts/m2) and shading at the site to develop a baseline.

Measuring
Once your system is installed, make sure it is operating as designed by measuring its electrical characteristics and the actual power output of the array. The performance of a photovoltaic array is based on its current-voltage (IV) curve. Use this meter to obtain the amount of solar irradiance necessary to calculate the IV curve of the power output.

Comparing and diagnosing
Even when installed correctly, a photovoltaic system may not be producing the expected electrical output. In order to produce the expected output the system needs to receive the correct amount of irradiance energy to generate the DC voltage that is fed into the inverter.

Applications

Installing, commissioning, and troubleshooting of photovoltaic (PV) arrays
Testing, documenting, and maintaining photovoltaic systems
Measuring irradiance, temperature, inclination and direction of the solar array
