Do black framed panels offer any advantage over normal frames?
Black framed panels offer a number of advantages over normal aluminum panels. Aesthetically they merge with your roof and do not look ugly and the coating on the frames give you additional protections against the natural elements. LG panels have 2.2ml of extra coating of paint and protective layers over the anodized aluminum frame. On average strong weathering reduces the top coat by 0.1 mm per annum. This means your LG solar panel frame will have 22 years protection against the elements, before the anodized aluminum is exposed to weathering. As a result, LG warranties against salt mist corrosion right down to the waterline for 12 years.
Many conventional solar panels have only got a 1 mm clear protective coating, meaning after 10 years the panel frame is exposed to the elements.
