Introducing a new wall-mounted bracket for solar panels from Ishii Construction, well-known for its single-pipe fittings for solar panels! The renewable energy target for 2050 has been revised from 200GW to 300GW. As the number of locations for installing solar modules decreases year by year, Ishii Construction proposes the option of "installing on walls." This bracket can be easily attached to locations where mounting frames cannot be installed, such as school building walls, railway viaducts, highway walls, and apartment balconies. Custom-made to fit the installation location. With a simple installation that only requires clamping the top and bottom of the panel, it can reduce construction costs. No anchor bolts or scaffolding are needed. ■ Key points for choosing this product: ◆ During installation, simply clamp the top and bottom of the panel against the wall. ◆ No anchor bolts or scaffolding required. ★ The catalog features a case study of installation on the balcony wall of an elementary school in Fukushima Prefecture! Feel free to check it out via the "PDF Download" link below. ★ In a pioneering effort nationwide, emergency shelters (elementary and middle schools) in Chiba City have begun introducing renewable energy facilities (self-generation).
