Structural assessment of existing rafters and purlins required.

This form of installation is more expensive due to higher material content and labour hours required to fix it. No structural assessment required with this installation as the weight of the new PV installation is offset by the removal of the roof tiles. The cost of this type of mount is approximately twice as expensive as an 'on roof '.

With a solar tracking array, the solar modules are always aligned according to the brightest position in the sky. This makes the overall energy yield of solar trackers up to 35 - 45% higher than fixed systems.

Straight forward installation. For ground mount, the array mast is fixed to an insitu reinforced concrete base. When mounted to a building it is bolted direct to the building frame.
