Lightweight Solar Panel for Rooftop Installations: DAS Frameless Corrugated Panel

View Products →


Frameless corrugated DAS solar panels have been rolled out as an innovative choice in the solar energy industry, delivering superior performance, aesthetic appeal, and ease of installation.

 

Understanding Frameless Corrugated DAS Solar Panels

A frameless corrugated backsheet solar panel is a type of photovoltaic (PV) module that eliminates the traditional metal frame and features a durable, corrugated (wavy or ribbed) backsheet design to enhance strength and flexibility.

DAS Solar’s corrugated design significantly reduces weight, simplifies installation, and improves overall energy efficiency.

Benefits of Frameless Corrugated Solar Panels

Some features make corrugated solar panels an appealing option for specific projects, particularly where durability, ease of installation, and energy efficiency are priorities.

Key Features:

Lightweight

Corrugated solar panels are lighter than conventional flat panels. This reduces the need for heavy structural support, making them easier and cheaper to install, especially in areas with weight restrictions or where the structural integrity of the roof is a concern.

Flexibility in Installation

Corrugated solar panels can be integrated directly into the roofing material, especially in corrugated metal roofs, reducing the need for additional mounting systems. This can streamline the installation process and reduce labour costs.

Enhanced Passive Cooling

The design allows air to circulate more freely behind the panels, preventing overheating. This cooling effect can improve the overall efficiency of the solar panels, as excessive heat can reduce the performance of traditional flat panels.

Durability

The corrugated design enhances structural strength and provides improved resistance to environmental conditions such as high winds, heavy rain, and snow, making it ideal for supporting solar panel installations. The ridges and grooves enhance the panels' structural integrity, making them less prone to damage compared to traditional flat panels.

Aesthetic Appeal

The corrugated look can blend well with certain architectural styles, particularly for industrial or commercial buildings, where a more modern or utilitarian appearance is desired.

Versatility

They can be used in a variety of applications, including commercial buildings, residential homes, and even in remote areas where traditional mounting systems may not be practical.

 

Corrugated Solar Panel Applications for UK Homes and Businesses

The innovative corrugated solar panels are perfect for residential and commercial projects.

Here are the best solar installation scenarios for these panels:

  • Residential Rooftops with Structural Weight Limitations
Residential Homes with Metal Rooftops

Homes that already feature corrugated metal roofs are ideal candidates for these panels, as they can be easily integrated with minimal adjustments. The corrugated design of the solar panels can match the roof, creating a cohesive look and saving on mounting system costs.

Urban and Residential Roofs with Limited Space

In areas with limited roof space, corrugated solar panels offer an efficient use of available area while providing the durability and weather resilience required for the UK’s variable climate.

Commercial and Industrial Buildings

Corrugated solar panels can be directly integrated into the roofing system of industrial or commercial buildings, especially those with existing corrugated metal roofs. This seamless integration eliminates the need for separate mounting systems, reducing installation complexity and costs.

Agricultural Buildings

The UK has a large agricultural sector, and many barns, greenhouses, warehouses, and silos often have corrugated metal roofs. Installing corrugated solar panels on these structures makes use of existing roof materials.

Agri-Solar Projects and Greenhouses

The panels can be especially useful in settings where light diffusion and airflow provide added benefits. Corrugated solar panels can be installed over greenhouses to provide power while still allowing for some natural light to filter through. This can be particularly useful in regions with high solar exposure.

Rural and Off-grid Installations

For off-grid homes such as cabins, farms, and remote facilities, where infrastructure may be limited, corrugated panels offer a practical solution. They require less heavy-duty structural support, making them ideal for locations without easy access to specialised installation equipment.

Other uses

Commercial spaces, schools, parks, carports, and sustainable building projects.

Top Benefits of DAS Solar Corrugated Lightweight Solar Panel in the UK

  • Ultra-Lightweight Solar Panels Frameless Design: DAS Solar corrugated lightweight panel weighs approximately 50% less than conventional glass solar modules, making it ideal for rooftops with limited load-bearing capacity. Its frameless corrugated design minimises or eliminates the need for additional support, which is especially valuable for older buildings and lightweight roofing systems.
  • Easy Installation & Reduced Labour Costs: Thanks to its lightweight and frameless design, this panel supports quicker, single-person installation, significantly reducing labour time and project costs.
    In many cases, it can be installed using adhesive mounting methods, avoiding the need for metal racking, drilling, or heavy equipment.
  • High Efficiency & Energy Output: With up to 20.8% module efficiency and excellent low-light performance, this panel delivers more energy per square metre, maximising return on investment.
    Equipped with Small Multi-Busbar (SMBB) technology and half-cell architecture, it ensures optimal performance throughout the day.
  • Durability & Long-Term Performance: Built with glass-free encapsulation and a corrugated aluminium foil backsheet, the panels demonstrate superior performance in terms of thermal management and structural resilience.
    A UV-blocking fluorine coating and rigorous testing for PID, ammonia, salt mist, fire, and mechanical stress ensure longer lifespan with minimal degradation.
  • Versatile Use Across Multiple Applications: This lightweight solar panel is ideal for a wide range of projects, including residential rooftops, commercial buildings, agricultural sites, and mobile or off-grid systems.
    Its adaptable design makes it ideal for installations where traditional solar panels are too heavy or complicated to fit, such as on older roofs, metal structures, or buildings with limited load-bearing capacity.
  • Warranty & Reliability: The panel is backed by a 12-year product warranty and a 25-year linear power output guarantee, offering long-term peace of mind and reinforcing its value as a reliable solar investment in the UK.
