Solar junction box

1 September 2010 Enclosures, Racks, Cabinets & Panel Products

A new four-rail junction box for terminating foils of a photovoltaic (PV) or solar panel has been released by Tyco Electronics. Featuring a low profile and a segmented solder area, this junction box saves potting material for solar industry OEMs when connecting the foils on their solar panels. In addition to the low profile, the overall dimensions have also been optimised to reduce necessary bonding material for mounting onto the back sheet.

Benefiting from its overmoulded low profile (only 13 mm height), the compact junction box can easily be applied on the back sheet of solar panels with silicon glue or double-sided adhesives. The connecting pads are located in separate rectangular openings for defined and easy soldering of the cross connects onto the pads. The low profile design has been achieved by using flat surface mounted device (SMD) diodes mounted on wide inner rails to guarantee excellent thermal management capabilities. The overmoulded cables feature a standard length of 1 metre and are terminated with Tyco’s own SOLARLOK connectors.
