Product Briefing Outline: Schreiner ProTech has designed a rugged, self-adhesive Pressure Compensation Seal (PCS), especially designed to provide solar module junction boxes with long-lasting protection against severe environmental conditions, preventing damage to sensitive electrical components. The product has already been selected by KOSTAL Industrie Elektrik to be integrated into their PV modules' junction boxes.

Problem: Condensation, specifically 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. While the value of alternative energy sources like solar power is increasing, the production costs of solar energy systems need to be reduced and reliability improved to ensure long-term viability.

Solution: new splash-proof (PCS) membrane vent material that delivers permanent 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. Ideally suited for use with solar power systems, Schreiner ProTech's new water-repellent membrane ventilates solar module junction boxes, thus reducing the harmful effects of condensation within the housing while offering reliable protection to PV modules that is vital to improving their longevity.

Applications: PV module junction boxes.

Platform: Schreiner ProTech's PCS meets the high standards of the IP 67. Additionally, the PCS can be customized and installed off the roll in a semi- or fully-automated process, enabling leaner manufacturing processes and lower production costs.

Availability: February 2010 onwards.
