Lightweight Flexible Solar Panel Structures
Lightweight, flexible, and efficient 400W solar panel, 70% lighter than traditional modules, easy to install and adapt to non-standard surfaces.
Lightweight flexible 400W PV panel for roofs, facades, and historic buildings.
The lightweight flexible 400W solar panel is a modern photovoltaic module designed for maximum versatility and ease of installation. It uses high-efficiency monocrystalline cells, and thanks to its glass-free construction, it weighs up to 70% less than standard panels. Its flexibility allows it to be mounted on irregular surfaces, lightweight roofs, building facades, historic buildings, temporary structures, and wherever traditional modules fail.
The panel is characterized by high efficiency, IP68 resistance, and a wide operating temperature range from -40°C to +85°C. Thanks to easy installation, low transport costs, and a 25-year linear power warranty, it is an excellent choice for both residential users and mobile energy systems looking for a durable and efficient power source.
The pressure of the panel, together with the specialized, dedicated mounting structure, does not exceed 5.5 kg/m². The solar panel can be glued directly to the surface. From today, you have the opportunity to use lightweight and aesthetic solar panels in places where it was previously impossible.
Roof Installations
In places where roof load capacity constraints pose a challenge, lightweight photovoltaic modules are the ideal solution. They minimise the load on the building structure and perfectly adapt even to complex roof shapes. Regardless of whether it concerns residential, commercial, or industrial roofs, lightweight modules allow for the effective acquisition and use of clean energy, without structural interference with the building, unlike standard glass panel modules.
Lightweight Construction, Exceptional Performance, and Elegant Design
Thanks to internally developed reinforced materials, lightweight flexible modules set a new standard in the lightweight installation category. They combine above-average durability through the use of double fiberglass with 96% transparency, low weight, and excellent flexibility, ensuring stable operation in various environmental conditions – from roofs with limited load capacity to building facades, industrial halls, and non-standard installations.
Key Construction Features
- Only 3.5 kg/m² – extremely light, without burdening the building structure.
- Thickness only 3.5 mm – ultra-thin profile facilitates installation and increases wind resistance.
- Up to 70% lighter than traditional glass modules.
- Up to 70% thinner – ideal for roofs with complex geometry and special applications.
