Multi-Contact (Stäubli Electrical Connectors) have been connecting any type of PV installation to the sun for more than 20 years, which resulted in 1 billion original MC4 connectors installed to connect more than 150 GW, which comes up to almost 50% of the PV power worldwide.
THE CONCEPT OF BANKABILITY - Minimizing risk, maximizing return
The following diagram shows the most common PV Module Failures by TUV Rheinland. They are sorted depending on the Risk Priority Number-RPN and as you can see the top failure cause in the PV panels is the use of different kinds of connectors. Another high failure cause is the connectors that are not properly connected:
The components for cabling (connectors, junction boxes, cables) play only a minor role in the calculation as they amount to less than 1% of the total initial costs (CAPEX), for connectors an even tinier percentage (approx. 0.003 %). Thus, choosing low-end connectors that are about 30 % cheaper in price compared to Stäubli connectors might signify an absolutely minor cost differential: that means a potential saving of no more than 0.001 % of the initial costs. Does this small amount saving worth the high risks???
