6 FAQs about [How to measure the insulation level of photovoltaic panels]

How to measure the insulation resistance of a solar PV system?

The IEC62446-1 standard describes two methods for measuring the insulation resistance of a solar PV system. 1. To short the positive and negative electrodes of the PV string, and measure the insulation resistance between the shorting point and earth. 2.

How do you measure the insulation resistance of a PV inverter?

One method is to measure the insulation resistance of each panel with respect to ground. This indirectly also measures the leakage current. The measurement is usually done before the turning on of the PV inverter or at least once or twice per day. For a 1000 Vdc system, normal practice requires insulation resistance to be more than 1 MΩ.

What is an example of PV panel insulation resistance measurement circuit?

One example of PV panel insulation resistance measurement circuit is shown in Figure 2. Assuming that the rated voltage of the individual PV panel is 1000 Vdc during bright sunny day, good PV panel insulation resistance recorded is 2 MΩ and bad insulation resistance is 100 kΩ.
