6 FAQs about [Photovoltaic panel factory test]
How is photovoltaic (PV) module performance determined?
State-of-the-art testing to precisely determine photovoltaic (PV) module performance. Accurate determination of photovoltaic (PV) module performance requires precise measurement of a module’s electrical characteristics to identify defects early in the development stages before they make it into the field.

How does TÜV SÜD evaluate PV modules?
TÜV SÜD evaluates the performance of your PV modules to ULC/ORD-C1703, UL 1703 and IEC 61730 safety standards as well as IEC 61215 and IEC 61646 performance standards. Our experts conduct factory audits that include initial and follow-up surveillance for manufacturing facilities.
How much voltage can a solar installation have?
A solar installation can have system voltage as high as 1500 V flowing in the solar module conductors such as cables, solar cells, and busbars. The insulation test can confirm the dielectric strength of glass, EVA, and backsheet under the influence of high voltage.
How do you test for insulation?
The insulation test feeds 1000 V plus 2 times the highest system voltage to the junction box output and the frame (after grinding off the surface insulation first), to test for the presence of a dielectric breakdown. Use high voltage across the bare frame and junction box output to test for insulation.
