The installed Top Lock (Yanegiken)

Yanegiken Co Ltd will release a metal fitting for fixing solar panels on seam-type folded-plate roofs, which are used as roof materials for large buildings such as manufacturing plants and commercial facilities, in March 2020.

Yanegiken (Takahama City, Aichi Prefecture) is a company that develops solar mounting systems and roof materials.

The fitting, "Top Lock," fixes a solar panel between seams of folded plates. It has a one-piece structure that eliminates the need to loosen nuts and open up the fitting. Its upper bolt, which is used to fix a solar panel, is slidable so that the location of a solar panel can be finely adjusted without reattaching the fitting.

The Top Lock is resistant to positive-pressure load because there are 21mm fins formed in the area that is in contact with roof materials and they efficiently release a load. Also, claws inside the metal fitting grasp the seam area to prevent dislocation caused by wind or snow. The fitting is made of aluminum and has corrosion and weather resistances.

The price of the Top Lock is ¥3,000/kW. It can be purchased only as a set including other components. Yanegiken aims to sell 50,000-60,000 units of the product per month.
