The SolarSpec™ Junction Box and Cable Assemblies are designed for installation on the back of mono- and polycrystalline photovoltaic (PV) solar modules. These products provide the interface between the conductor ribbons on the panel and the dc I/O cables.  Molex SolarSpec products are  for applications in the solar and renewable energy industry.

“Tremendous growth within the solar-power market is fueling competition in the manufacture of PV solar panels,” Peter Commane, product manager of Molex Inc. says. “By using automated production lines, assembly time of a junction box to a PV panel can be considerably reduced. The SolarSpec Junction Box from Molex is specially designed for pick-and-place panel assembly.”

The product features spring terminals connecting the base directly to the PV ribbon conductors without the need for retention clamps or clips. Optional  Solder Charge Technology™ facilitates high-speed assembly and eliminates the need for hand-soldering of the ribbon, significantly reducing any process variation. Optional double-sided tape eliminates the need for curing time on silicone when attaching the connector base to a module.

The product assembly is supplied with two removable dc cables available in dual-qualified (TÜV and UL) or single-qualified (TÜV) formats. 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. The junction box assembly houses the diodes and dc cable in the “removable” top cover of the housing to facilitate repair or replacement. The top cover and base module are secured together with a locking mechanism to prevent accidental exposure of high-voltage contacts.
