Wood instead of metal: The more sustainable substructure for photovolt

When talking about photovoltaics, the focus is usually on modules, efficiency, and power yield. One component often goes unnoticed, although it significantly influences the eco-balance of the entire system: the substructure on which the modules are mounted. At Dietmar Allig PV Bau, this is deliberately not an aluminum or steel frame, but wood. Why wood instead of metal at all? Metal substructures are industrial standard – for good reason: robust, durable, widely used. However, their production is energy and resource-intensive. Wood offers an alternative that performs differently in several respects: Significantly lower CO2 footprint in production compared to conventional metal frames. Natural CO2 storage: As long as the wood is installed, the bound carbon remains stored. Recyclable at the end of its useful life, without complex separation processes. Easy to assemble – even for laypeople, without welding or special tools. It is important to note that wood does not have to compromise on stability or durability. Properly processed and constructed, a wooden substructure supports solar modules for decades – just like a metal construction, but with a better eco-balance. The material structure in detail The support elements from Dietmar Allig PV Bau consist of a sandwich structure with white melamine-coated birch plywood: The white melamine outer layers protect against weathering and provide a clear, modern look, while the birch plywood core provides stability. At the edges, the warm, natural wood remains visible – a deliberate design detail that shows what material the construction actually consists of. The inventor's idea behind it The decision for wood is no coincidence, but the starting point of the entire product idea of founder Dietmar Allig. Dissatisfaction with existing solutions – opaque modules on heavy metal frames – led to the development of a proprietary concept: translucent modules on a wooden construction that can be produced, assembled, and eventually dismantled more sustainably. What wood means for your project Whether it's a terrace, carport, or agri-PV area: a wooden substructure blends more harmoniously into garden and landscape designs than cold metal, can be modularly expanded, and fits the basic idea of double land use – thought sustainably from construction to module. Frequently Asked Questions about Wooden Substructures (FAQ) Does a wooden construction last as long as a metal construction? Properly processed and constructed, a wooden substructure is designed for longevity and for permanent outdoor use. Is wood weather-resistant enough for outdoor use? The white melamine coating protects the birch plywood core from moisture and weathering, while the edge detail leaves the natural material visible. Why is wood more sustainable than metal? Wood stores CO2, is recyclable, and requires significantly less energy in production than the extraction and processing of metal. Can I assemble a wooden construction myself? Yes, the modular system is deliberately designed so that it can be assembled without special tools or professional training.
