As solar panels became cheaper, they began to take more place in our lives. Panels, whose installations are increasing day by day, appear in an interesting place this time. In Switzerland, roadside retaining walls were covered with solar panels.A canton in Switzerland developed an interesting and creative solution, covering roadside retaining walls with 756 glass solar panels, with the aim of producing at least 40% of its electricity from renewable energy in 2035.
Panels with a total power of 325 kW will produce 230,000 kWh of electricity annually. The electricity produced can meet the needs of approximately 52 houses.
The panels were attached to the walls at an angle of 75 degrees with adhesive and fixed with screws. Since it is close to asphalt, anode coating was applied to the panels to prevent corrosion.
Of course, since the panels are vertical, their efficiency will be low since they cannot receive the sun’s rays vertically. However, it is stated that the efficiency of vertical panels increases since the sun is not directly overhead in the northern hemisphere in winter. After all, using an unused, dead area to generate electricity is a creative and nice idea.
