Groomed for thin-film solar modules, the SOLARLOK 1-rail junction box debuts as a solution for photovoltaic modules in which the positive and negative leads each have their own access point. Requiring potting, one small, flat junction box installs in two different places on the back of such panels. The junction box measures 58 mm x 30 mm and 13 mm high. It installs quickly and discreetly and is also suitable for building-integrated photovoltaic systems. TE CONNECTIVITY, Harrisburg, PA. (800) 522-6752.
