Our 55w pv panel: 800mm x 540mm, are polycrystalline panels made from wafers of silicon, laminated between an impact-resistant transparent cover and an eva rear mounting plate. They are constructed with a lightweight anodised aluminium frame which is predrilled for linking to other frames/roof mounting structure, and have a waterproof electrical terminal box on the rear.

Uses bypass diodes that take the panel out of circuit if the panel is in a string, and shaded by the sun - this allows grid-tie systems to continue to output at slightly reduced rate if anything casts a shadow on one of the panels.
