How is a solar system installed on a metal roof?
Metal roofs are commonplace in New Zealand. The solar power mounting system used for steel roofs uses special L brackets to match the profile of the roof. The racks that hold the panels generally don’t require drilling into the roof structure at all but use the existing installed roof screws. Care must be taken to ensure the screws and brackets are properly sealed after the installation. Installations on metal roofs, if these roofs are not extremely steep, is slightly easier than on tile roofs.
