The Valsa Standard Ground Mounting structure solution provides a quick-install, secure structure for PV Solar panels for ground installations. It is the ideal option when roof space is not available or when only ground space can be utilised.
The modular design reduces the number of components and is universal, suitable for all size PV Solar panels and can accommodate various configurations from 1 to 40 panels per table in a single row portrait orientation with a fixed tilt angle or 4 to 80 panels per table in a double row portrait orientation with fixed tilt angle. This allows for the installation to be set at a perfect angle to optimise energy production for different countries.
The solution is available for either In-land or coastal:
- In-land applications for more than 20 km away from the sea manufactured from Pre-Galvanised material
- Coastal applications for up to 20 km from the sea is manufactured from Hot Dip Galvanised material
The choice of the best ground mounting solution is influenced by the soil composition (either standard footing for concrete strip foundations, pile driving or concrete footing for slab installations will be used).
For larger installations steel piles are rammed into the ground. The thickness, length and depth of the piles depend on the soil composition confirmed through geological survey results. From sandy soil conditions to rocky soil, the length of the pile will be determined by the pull-out test performance of the soil. The adequate size pile will be specified by the engineering simulation done for the site conditions.
Where the soil is not suited for piles an anchor system can be used in the form of a concrete strip foundation or a concrete slab. This is often used in commercial installations where ground penetration is not permitted or for smaller size installations.
The mounting structure meets structural engineering requirements and have been designed and manufactured to International standards and are in line with SANS regulations.
