6 FAQs about [Photovoltaic support structure performance certification]
Do photovoltaic modules need a certification test protocol?
A certification test protocol that delivers an accurate and credible estimate of component and system performance is needed. Even with current component qualification information, photovoltaic module performance data must be modified to account for actual conditions.
Can PV modules be used in extreme environments?
Demonstrate long-term safety and performance of PV modules for use in extreme environments with UL certification. PV modules are installed in extreme environments such as heavy snow, high winds or desert conditions. Innovative PV products are also replacing traditional building materials such as roof coverings and curtain walls.
What types of PV modules do ul solutions offer?
UL Solutions’ wide range of services for PV modules cover all types – crystalline, thin-film, building-integrated PV (BIPV), concentrator PV. We test and, as applicable, certify to: Type approval to IEC 61730-1 and IEC 61730-2.
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.
What is a good test voltage for a PV module?
For example, consider a single-ended test of a PV string with Voc of 475V and a PV module maximum system voltage spec of 1000V. Setting the meg tester’s test voltage to 500V will keep all points in the circuit below 1000V.
How is photovoltaic system performance determined?
Photovoltaic system performance can be determined as the ac system output under Performance Test Conditions (PTC)3 which are defined as Data should be sampled at an interval of no greater than 60 seconds and averaged over an interval of no more than 30 minutes.
