Molex Inc. has released SolarSpec junction box and cable assemblies designed for installation on the back of mono- and polycrystalline photovoltaic solar modules. These products provide the interface between the conductor ribbons on the panel and the DC I/O cables.
The SolarSpec Junction Box features spring terminals connecting the base directly to the PV ribbon conductors, without the need for retention clamps or clips. Optional patented Solder Charge Technology facilitates high-speed assembly and eliminates the need for hand-soldering of the ribbon, significantly reducing any process variation, the company notes. Optional double-sided tape removes the need for curing time on silicone when attaching the connector base to a module.
The compact dimensional profile can supply current ratings comparable with traditional larger products. The SolarSpec Junction Box assembly is supplied with two removable DC cables available in dual-qualified (TUV-certified and UL-certified) or single-qualified (TUV-certified).
The junction box contains bypass diodes to protect the PV panel from reverse current during hours of darkness, shade or when covered by leaves or other debris, Molex adds. The junction-box assembly houses the diodes and DC cable in the removable top cover of the housing to facilitate ease of field repair or replacement in the event of damage or wear. The top cover and base module are secured together with a locking mechanism to prevent accidental exposure of high-voltage contacts.
