The company has developed a new splash-proof PCS membrane vent material that delivers weather resistance and prevents the intrusion of water, oil and dust within the junction box housing, even after the component has been submerged into water for 30 minutes. Condensation, when formed in the photovoltaic (PV) module and transferred into the junction box, can decrease power output and corrode electrical contacts resulting in safety issues.

Ideally suited for use with solar power systems, Schreiner ProTech’s water-repellent membrane ventilates solar module junction boxes, reducing the harmful effects of condensation within the housing while offering reliable protection to PV modules.

Schreiner ProTech’s PCS meets the standards of the IP 67, as well as all of the solar industry’s requirements in terms of cost-reduction, safety, quality and technical performance, the company claims. Additionally, the PCS can be customized and installed off the roll in a semi or automated process, enabling leaner manufacturing processes and lower production costs. Schreiner ProTech’s PCS has been selected by Kostal Industrie Elektrik to be integrated into its PV modules’ junction boxes.
