Solar Panels 310W

(£187.50 excluding VAT)

Wondrwall uses solar panels to generate electricity for the home. The solar panel array is sized to ensure that the home generates as much electricity in a year as it consumes. Powered by high-efficiency PERCIUM cells, these high-performance modules provide a cost-effective solution for lowering the levelised cost of energy (LCOE). We use 5 busbar solar cell technology to improve the efficiency of modules, give a greater generation capacity for the roof space available and offer a better aesthetic appearance. The panels deliver a higher module conversion efficiency of up to 19.85% due to the half-cell structure. The advanced glass and cell surface textured design ensure excellent performance in low-light environment. The panels are certified to withstand wind load (2400 Pascal) and snow load (5400 Pascal) and have high durability against extreme environmental conditions such as high salt mist and ammonia.
