STS Releases Addendum To STS-STD-PVM1 For BI-FACIAL PV Modules To Support Module Buyers Better Secure Quality At Pre-Dispatch Inspection


STS, the industry leader in PV modules quality control, announces today the release of its Addendum to STS-STD-PVM1:2018© for Approval of PV Modules Manufacturing and Dispatch.

This new industry-level standard is the result of an 8-months work on bi-facial PV modules, that included technical studies, consultations, manufacturing witness and lab testing in collaboration with laboratories and manufacturers.

The Addendum, referenced STS-STD-PVM1-2:2018© AA1, complements the initial standard released by STS in 2018 and adds requirements specific to bi-facial modules, among which:

- production control requirements to test rear side modules performance during mass-production;

- adjustment of criteria for manufacturers’ quality control processes to include PO and POE materials;

- electrical measurement method to rear side of the PV modules;

- components placement requirements.
