Abstract
Due to climate change, the ingoing transition to renewable energy sources has created demand for solar panel support structures. Currently most of these structures are build either in aluminium or steel with concrete blocks providing ballast against uplift forces. The potential environmental savings of applying timber instead of aluminium are quantified on the specific case study in Norwegian climate conditions and fixing system solution from local supplier (LOBAS AS). Timber-beam mounting system with steel connectors and fixings has on average 76% less kg CO2-eq/m 2 emissions than aluminium-profile system with aluminium connectors and steel fixings in production stage. Reuse of reclaimed impregnated timber can results in up to 30% further emission saving while remaining production emissions are locked in steel connectors.
