Due to the site proximity to the sea Hyundai Solar PV modules were chosen as they have IEC 61701 salt mist corrosion test certification. All mounting equipment was anodised aluminium and high grade stainless steel to ensure continuation of mechanical performance. Due to the shallow pitch of the roof elevation rails were employed to increase the mounting angle of the PV array. This resulted in the improvement of the modules ability to self-clean and also increases energy yield.
