Engineered to support heavy-load solar installations, rooftop arrays, and tracking systems in demanding alpine terrain.
Switzerland is experiencing an aggressive expansion in solar capacity, driven by the national "Energy Strategy 2050". To meet winter energy deficits, Swiss developers are rapidly planning and deploying large-scale utility installations, particularly high-altitude alpine solar projects. These environments present unique mechanical stresses, including massive snow loads, sustained UV radiation, and rapid thermal cycling between day and night.
Unlike standard rooftop installations in mild regions, Swiss alpine and municipal installations demand connection components with exceptionally high tensile strength, extreme IP-rating longevity (IP68-rated), and low contact resistance. In sub-zero temperatures, standard plastics degrade, and moisture ingress triggers severe ground faults, which can lead to high-altitude maintenance calls costing thousands of Swiss Francs (CHF).
As Switzerland pushes forward with PV electrification, the shift from 1000V DC system architecture to 1500V DC has become standard practice for utility-scale deployments. Operating at higher voltages reduces line losses and allows for longer string runs, minimizing the quantity of combiner boxes. However, this creates a major safety risk if the branch connectors are not designed to withstand elevated voltage arcs.
Our Solar Branch Connectors utilize premium polyphenylene ether (PPO/PPE) engineering plastics. These materials maintain structural flexibility and impact resistance even at -45°C. They exhibit superior resistance to ozone-induced cracking and withstand the intensive UV radiation found at elevations above 1,500 meters in the Swiss Alps.
To prevent localized thermal runaways (hotspots) in high-amp parallel configurations, our contacts feature high-purity copper plating with thick silver/tin finishes. By ensuring a contact resistance of < 0.25mΩ, these terminals maximize system efficiency, protect critical string inverters, and guarantee the safe collection of generated power.
Engineered to resist intense solar UV radiation and rapid temperature fluctuations typical of Swiss alpine solar installations.
Dual-ring IP68 sealing mechanisms prevent water ingress caused by melting ice, snowpack compression, and heavy rainfall.
Fully compliant with EN 50521 and IEC 62852 standards, facilitating smooth project approval by Swiss safety authorities.

Answering crucial technical questions from Swiss engineering procurement teams and installers.
High-altitude locations (above 1,500m) feature thinner air, reducing electrical insulation properties and increasing the risk of voltage arcing. For Swiss alpine projects, it is imperative to use connectors with a rated impulse voltage of at least 12kV or 16kV and certified 1500V DC ratings. Additionally, the polymer housing must feature specialized UV-stabilizers to prevent premature cracking under high solar radiation.
We utilize high-grade, cross-linked engineering polymers (PPO/PPE) that maintain high mechanical elasticity at temperatures as low as -45°C. Lower-quality PVC or untreated plastics become brittle and crack during thermal cycling, which allows moisture ingress. Our materials are fully tested and certified under TUV/IEC standards for cold-impact resistance.
Yes. Switzerland's Federal Inspectorate for Heavy Current Installations (ESTI) enforces strict compliance with IEC 62852 standards for PV connectors. Our solar connectors carry formal TUV and CE certifications, validating that they fulfill all safety, mechanical resistance, and electrical conductivity requirements demanded by Swiss law.
Thanks to our automated production lines and integrated supply chain in Wenzhou, standard OEM configurations can be prototyped within 7-10 business days. Bulk orders are typically completed within 15 to 25 days, depending on custom cable length specifications and connector variations, with efficient shipping options directly to major Swiss hubs such as Zurich, Basel, and Geneva.
