Product catalog summary

Introduction
a2-solar is a leader in building-integrated photovoltaics (BiPV) with over 30 years of experience. They specialize in integrating solar technology into building designs, enhancing both functionality and aesthetics.

Key Project: New City Hall in Freiburg, Germany
The New City Hall in Freiburg features one of Europe's largest solar façades, designed and delivered by a2-solar. The façade covers 13,000 m² and generates 220 kWp using 880 glass-glass solar modules. These modules are 3.5 m tall and 60 cm wide, with a 7 mm spacing for high transparency. This design meets European energy efficiency regulations and contributes to the building's zero-energy status.

Technological Features
a2-solar offers multifunctional modules that provide architectural functionality, color variations, and options for shading and cold facades. They use mono-, polycrystalline, or bifacial cells, and offer glass-foil or double glass construction. Additional benefits include privacy, sound isolation, electromagnetic shielding, and burglary protection.

Innovative Solutions
a2-solar's BiPV solutions enhance energy efficiency and architectural design. They offer weather protection, thermal insulation, and shading. Their AWESO mounting system allows for easy installation and customization to meet architectural needs.

Applications Beyond Buildings
Photovoltaics are used in sound-proofing walls, bifacial modules, and special modules for infrastructure like bridge railings and public lighting. Mobile solar systems are also gaining popularity, with a2-solar offering customer-tailored modules in various shapes and sizes.

Conclusion
a2-solar combines advanced technology with design to create innovative solar solutions for buildings and beyond. Their expertise in BiPV and automotive solar systems positions them as a high-performance innovator in the industry.
