For this customer on the sea front in Hayling Island, Hampshire, we installed a 4kW solar panel system. Due to the direct proximity to the sea the solar panels selected for this installation were 16 x Canadian Solar 250W, which are salt mist corrosion tested. On this occasion we used a Fronius 3.6 IG TL inverter. This Austrian inverter has a 10 year warranty for added peace of mind. A Geo Solo display was used to monitor the solar system performance. In order to achieve a 16 solar panel (4kW) system, it was necessary to accurately measure the roof. We then design the solar panel layout, to enable the customer to visualize the end result.
