Why Are Vertical Solar Tubes Not Afraid of Leaves?
Traditional flat solar panels are prone to leaf accumulation, which blocks sunlight, reduces power output, and demands frequent costly manual cleaning. Vertical solar tubes offer a structural fix: their columnar tubular layout has almost no horizontal resting surface, so leaves, pine needles, and dirt slide off with gravity or a light breeze. The textured super-white tempered glass further resists debris adhesion. Beyond leaf resistance, these vertical modules provide 360° omnidirectional light
