Why Commercial Rooftop Solar Starts with the Roof
Jason McCabe, Technical Director for the UK and Ireland at Clenergy, discusses the practical realities of commercial rooftop solar, from roof condition and structural checks to installation risk, mounting system design, logistics and the need for stronger industry standards. The article highlights why successful commercial rooftop solar projects must begin with a thorough assessment of the roof itself. Jason shares his insights on key factors such as roof load capacity, roof covering and substructure condition, correct fixing selection, installation quality, supply chain considerations, and the importance of localised mounting system design for different markets.
