These sturdy and simple low level solar PV mounting structures, made from galvanised 2" tubular steel and can be used together to make up a solar array of any size. Two versions are available to allow fixing either to a concrete foundation base or direct into the ground. This version is a concrete free version and comes with a 90cm pole that is driven into the ground using a sledge hammer or vibrating post driver. For this type of anchor to be secure the ground should be undisturbed, well consolidated soil. Check for buried services and obstacles before driving the poles into the chosen location.
