6 FAQs about [Photovoltaic panel impact resistance test solution]

How to measure the insulation resistance of PV modules?

To safely measure the insulation resistance of PV modules, it is recommended to conduct the measurement with a method that does not involve a short circuit. Also it is important to use a insulation meter that can measure accurately even when the current from the PV modules flows through a closed loop.

Does a PV module need a higher hail impact test?

So as required by the IEC 61215, higher hail impact testing may be specified by project owners, which may partially quantify the risk of damage and financial loss in the event of a practical hailstorm. The impact of hail on the PV module is investigated in detail in the laboratory test set up to understand the feasibility of the present standard.

Can PV modules withstand hail?

Hail tests on photovoltaic (PV) modules should be beyond the conventional testing. Power reduction of 21.47% is observed in glass to backsheet PV modules under hail. PV modules with front glass thickness of 4 mm can withstand severe hail damage. Use low wet-leakge current resistance modules for high hail-prone regions.

How is a solar PV module analyzed?

First, the analysis of the results is carried out in term of global response, i.e., by examining the relation between indentation depth and time. Then, a more detailed analysis is carried out by inspecting the stress field inside the PV module, with particular focus on the layer containing the solar cells.

What is insulation resistance test & wet leakage current test set up?

Insulation resistance test and wet leakage current test set up Insulation resistance test and Wet Leakage current test set up is used to perform the Insulation resistance (IR) test, Wet Leakage current (WLC) test, Dielectric withstand test and Ground Continuity test of PV modules.

What is the scientific novelty of a solar PV module?

The scientific novelty is the optimization of the PV module based on experimental data under hail tests. Results show that the there is a continuous irreversible effect of the excitation force on the PV modules in the event of hail, and it can reduce the power output.
