In the contacts for its junction boxes, Kyocera is opting for high-quality soldered joints from the outset, rather than clamped joints, and is thus offering dependable protection against fire hazards.
If lower quality is employed, defective electrical connections may lead to a fire in the junction box. Soldered connections are the safest form of creating the contact and, in connection with complete encapsulation of the junction box, provide protection against corrosion and overheating. Kyocera already uses flame-retarding components in its manufacturing, which is why the new junction box has also achieved the highest non-combustibility rating of 5V-A in compliance with UL94.
Solar modules from Kyocera withstand high loads. This is also the reason why the company’s solar plants have been specifically chosen for sites with extreme weather conditions such as in the Alps, on top of the Jungfraujoch, and for the “Princess Elisabeth” research station in the Antarctic. In its production, Kyocera attaches particular importance to covering the entire value-added chain itself and thus guaranteeing quality and performance of the modules.
Both the new junction box and the connecting cables comply with the requirements of current IEC standards. The tried and tested Multi-Contact® PV-KB/ST 3 plug-in connectors have been retained, which enables trouble-free combination of modules with “old” and “new” junction boxes.
Introduction of the new junction box is scheduled for October 2009.
