A key factor in a well-performing photovoltaic system is optimal placement on the roof, based on the intensity of the sunlight (irradiance) striking the array. The amount of current a PV module can produce is directly proportional to the irradiance striking the array, this measurement is critical when validating the performance of a PV system. The Megger PVM210 Irradiance Sensor provides technicians the ability to correlate the current output from their array with the irradiance for accurate calculations on the array performance.
You can operate this compact, pocket-size instrument single-handedly because the solar detector and meter are conveniently housed in one neat device. This feature proves especially handy when using the instrument on a sloping roof or while perched at the top of a ladder.
To fully verify performance pair your Irradiance Meter with the Solar Clamp Meter (DCM1500S) to obtain accurate readings of amperage and operating temps of the modules.
