Isc & Voc Monitoring

Description

The ISC & VOC monitoring system is developed and manufactured by Kintech Engineering to accurately measure the Isc and Voc values of two solar PV panels simultaneously. It is used for detection of fault symptoms, analysis of solar panel degradation and inclement weather conditions on the solar panels installed in the solar PV plant, including the effect from soiling.

Category:

With its small form factor, the Isc & Voc device is meant for use on solar PV panels already installed in the solar PV plant. The device can measure the Isc and Voc values from up to two solar PV panels simultaneously and when supplied as part of a complete measurement kit (including the Orbit 360 data logger) an open-source python script can be included to calculate the soiling rate.

Applications

Isc & Voc monitoring of solar PV panels. The Isc output can be used for irradiance calculations whereas the Voc output can be used for cell temperature calculations. The combination of both Isc and Voc outputs can be used to estimate the solar power output.
