PV Connectors: Task Group 10

Task Group 10 is focused on durability issues related to junction-box connectors.

Task Group 10 is focused on durability issues related to PV connectors. Both manufacturing and deployment issues are included for connectors. The group will examine evidence for and initiate tests on durability and reliability of contacts, and susceptibility to mechanical or corrosive failure mechanisms. Plastic wall materials need to retain their strength against UV exposure. The connectors should keep the joints rigid and interior sealed to humidity and dust, and protect the connector joints against reasonable external mechanical forces during installation and use. Standards and procedures are needed at the times of manufacture, installation, and for field repair/retrofit of connectors.

Progress Update

Task Group 10 has conducted a survey to prioritize efforts, reviewed standards already in place for their applicability to durability studies, and is now working through a DFMEA to identify the most critical failure mechanisms.
