PVTIME – As cities worldwide strive toward carbon neutrality and sustainable growth, DAS Urban solutions offers innovative PV technologies that seamlessly integrate solar power into urban infrastructure. By focusing on three key areas of PV + transportation, BIPV, and lightweight rooftop systems, DAS Solar is at the forefront of driving urban energy transitions. These solutions not only provide clean energy but also enhance urban environments through their aesthetic and functional integration.
Lightweight Module Solutions: Redefining Rooftop Solar
In urban areas, rooftop space is often limited, and many buildings face weight constraints that make traditional solar modules unsuitable. DAS Solar’s lightweight modules provide an innovative solution to this challenge, offering a product that is 70% lighter than conventional modules while maintaining a power output from 420W to 510W.
These modules are designed with polymer and metal composite materials, replacing the traditional glass and aluminum frame. Weighing only 4.2 kg/㎡ and with a thickness of just 4 mm, they significantly reduce the load on rooftops, making them ideal for buildings with limited structural capacity. This innovation was successfully applied in a rooftop solar system in Tianjin, where the lightweight modules are installed on steel roofs without the need for reinforcement, meeting stringent weight and safety requirements.
With simple installation processes, high compatibility, and minimal maintenance, DAS Solar’s lightweight modules are a game-changer for urban distributed PV projects. They also feature UV inhibitors embedded in the material’s molecular chain, ensuring excellent UV resistance and a long service life. Additionally, their micro-patterned surface reduces glare and light pollution, making them suitable for densely populated urban environments.
BIPV: Integrating Solar Power into Building Design
Building-Integrated Photovoltaics (BIPV) represents a key part of DAS Urban solutions, offering a comprehensive way to integrate PV systems directly into building materials. BIPV systems not only generate clean energy but also enhance the aesthetic appeal and functionality of modern buildings.
A prime example of DAS Solar’s BIPV solutions is showcased in its first facade solar project in Quzhou. The installation features lightweight shingled modules which can reduce the load by approximately 70% compared to traditional systems with the same power output. This substantial weight reduction eases structural demands on buildings and enhances overall safety.
Incorporating advanced shingling technology, this project balances visual appeal with functionality. The system is built with a UV-resistant composite front plate that offers excellent self-cleaning properties, ensuring high performance and long-term durability. Additionally, its back-adhesive installation method simplifies the process while delivering superior safety, waterproofing, and fire resistance—all backed by a robust product warranty.
PV + Transportation: Revolutionizing Green Mobility
The transportation sector is one of the major contributors to carbon emissions, accounting for around 10.4% of China’s total emissions. To address this challenge, DAS Solar has introduced the PV + Transportation model, which combines solar energy with transportation infrastructure, such as highways, service areas, and parking facilities, to support the carbon neutrality.
An exemplary project is the Qingyin Expressway Jinan East Service Area, where DAS Solar collaborates with Shandong High-Speed to create China’s first zero-carbon service area. This project effectively utilizes high-efficiency N-type modules and lightweight modules to power the service area through solar energy, significantly reducing its reliance on traditional fossil fuels. The installation of flexible mounting systems in the parking areas and alongside the highway maximizes energy generation while making efficient use of available space.
Similarly in Guizhou, DAS Solar’s innovative approach has led to the integration of solar power along the Biwei Expressway, where distributed solar stations are installed at interchanges, toll stations, and parking areas. This project also includes EV charging stations, small wind turbines, and solar-powered parking lots, contributing to the region’s sustainable development by ensuring reliable clean energy supplies.
A Holistic Approach to Urban Sustainability
Through DAS Urban solutions, the company is redefining how cities can incorporate clean energy into their infrastructure. By seamlessly integrating solar power with transportation networks, building structures, and urban rooftops, DAS Solar’s solutions not only reduce carbon emissions but also enhance the functionality and aesthetics of urban environments.
As cities continue to grow and strive for sustainability, DAS Solar’s comprehensive approach provides a blueprint for creating energy-efficient, resilient, and aesthetically pleasing urban landscapes. These innovations are paving the way for a greener and brighter future where cities are powered by the sun.
