Powertech 12V Monocrystalline Solar PanelThese high performance monocrystalline solar panels are much smaller, thinner, higher in efficiency and more affordable than our previous models. The manufacturing process for this range uses 36 pieces of 156x156mm A grade solar cells cut into defined sizes with 4 grid lines, which provides excellent performance under low light environments. Each panel is designed to withstand harsh environmental conditions with a durable anodised aluminium frame and
