Against great odds: Solar power in the Antarctic

Temperatures below -89 °C, winds over 200 km/h, extreme variances in hours of sunlight, with up to 16 hours in the summer and only two during winter, pose tremendous challenges for both research teams and equipment.

Innovative solution: Solar power generation in urban areas

In a pilot project, the first solar cycle path roofing was put into operation in the German city of Freiburg. In densely populated areas, this project demonstrates the coexistence of traffic surfaces and solar energy generation with extremely durable glass-glass PV modules

Avoid Cross-mating of PV Connectors

Not only the selection of quality components but also their correct handling is crucial for the PV plant's profitability and safety. Therefore, it is essential to know and understand the technical impacts when installing and connecting the various elements.

The First PV Connectors for Harsh Environmental Conditions

Requirements for operating electrical installations in ambient temperatures over 70°C or at altitudes higher than 6,500 feet differ from the requirements for standard installations due to the different climate conditions.

Small components. Big impact.

White Paper contributed by Stäubli Electrical Connectors: Attention to the smallest detail always shows the biggest returns. Connectors may be small components, but their influence on the efficiency and bankability of a PV project is undeniable.
