Insulation resistance measurement of PV panels in a wet environment is a process requiring specialised equipment in order to be carried out correctly and effectively.

According to IEC61215 standard par.10.15, , in order to identify and document Riso insulation resistance problems in PV modules in a humid environment, they must be tested in a suitable container, at a temperature of 25°C and in water with a specific electrical resistivity of less than 3,500Ω*cm.

Kmetrics boasts the appropriate equipment to identify and certify insulation resistance problems that are usually due to PV modules or wiring.
