They were super excellent and helpful and as fast as a speeding jaguar on fire trying to find a water hole to extinguish the flames. In another words I would highly recommend and will be using again in the future. Thanks bimble solar .
You must use at least 4 module clamps for one solar panel ( 2 end clamps included). For example two solar panels one above the other in landscape would required 6 Clamp fit, 2 mid clamps and 4 end clamps.
Although typically this system will use 4 fixing points per module. At high wind or snow loads or with large modules it may be required to use 6 fixing points for extra safety.
