Microcracks are usually created by external impact to the panels, so a good way to prevent microcracks in solar panels is to toughen up the overall product by design.
Key components that add strength to a module are glass and frame.
By choosing the tempered glass that can withstand the impact of advanced hailstone tests, WINAICO modules can withstand the collision of 35 mm ice balls launched at 100 km/h.
This advanced test contains more than 4 times the kinetic energy of standard IEC hailstone tests and makes sure WINAICO systems can survive the impact of stray golf balls.
WINAICO modules’ frames are constructed using L-shaped corner keys to lock frames in place, and can withstand up to 5400 Pa of mechanical load, more than 900 kg, and spread evenly across the panel.
