STRONG, YET LIGHTWEIGHT
95% of the total weight of the structure consists of standardized top-hat or C shaped roll formed profiles. The roll formed profiles are both lightweight and easily manufactured locally (near the installation site) if needed. Since roll forming is a key manufacturing procedure in the steel building construction industry, these profiles can be produced in large volumes on a low cost.
The roll formed profiles present an exceptionally high stiffness to weight ratio and with the proper design, this characteristic is inherited to the whole structure. This high stiffness and stability of the structure enables the foundation feet to be up to 4 m apart, reducing labor and material costs during assembling (compared to the costly narrow spaced foundations).
The structure can be continuous, or repetitions of standardized table lengths (e.g. 40, 42, 44 etc PV modules per table).
The installation of the DP15 is quick and easy, with optimized functionality in every step of the procedure. There is no need for field work (drilling, cutting, welding, etc) and there is no room left for decisions during the assembling, thus eliminating installation errors and the need for staff expertise.
HIGH FOUNDATION PLACEMENT TOLERANCE
The foundation pole protrudes from the ground less than 15 cm. Since the ramming machine’s guiding mechanism is about at the same height, the rammed pole can be installed with maximum precision. Even in difficult soils that don’t allow good foundation precision, the innovative adjustment principle can absorb foundation misplacement up to ±10 cm towards any direction.
A single base design and a single type of clamp can be used to install almost all types of framed panels, independently of the PV module’s outer dimensions.
SUITABLE FOR ANY TERRAIN
HIGH MISALIGNMENT TOLERANCE
Since the DP15 does not use direct mounting on foundation poles (i.e.: poles protruding above ground 1,5-2 m) but uses the foundation infrastructure as something to connect the above ground system on, a high foundation misalignment tolerance can be achieved.
HIGH TERRAIN ABNORMALITY ABSORPTION
The DP15 system can easily absorb terrain abnormalities in both, north to south and east to west directions.
The north to south inclination absorption is achieved by simply changing the height of the easily adjustable back legs of a table until the PV mounting surface is at the desirable inclination.
The east to west inclination absorption is achieved by using independent tables and by simply making sure during the installation of the foundation that all the connection points of a table are on the same plane regardless of the plane’s inclination.
