DP15

Dual Pole, PV Mounting System

Minimized and simplified logistics

The Most Cost Effective mounting system for utility scale PV Installations

UNIQUE DESIGN

The DP15’s design is based on our accumulated design knowledge and extensive field experience. Every detail has been thoroughly engineered to have the minimum impact on the projected final cost per installed square meter of PV modules and consequently on the levelized cost of energy (LCOE).

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).

EASY INSTALLATION

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.

OUTSTANDING FLEXIBILITY

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.

Design for Flexibility

Adjustable connections in every point allow easy installation even in the most nonuniform terrains.

Only a single bolt size is used throughout the Installation procedure.

4 DIFFERENT FOUNDATION OPTIONS AVAILABLE

1

RAMMED POLE

One of the most common and cost effective foundation solutions in PV installations.

2

CONCRETE PILE

A good alternative to the rammed pole foundation.

3

BALLAST

A solution that does not require any special machinery.

4

DIRECT MOUNTING

Installation on pre-existing structures such as rooftops or concrete yards.

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.

MAXIMUM FLEXIBILITY AND COMPATIBILITY

The DP15 can bear any type of PV module, framed or glass-on-glass.

All the framed modules are directly fixed on the structure using the PV-CLAMP. In cases that the client prefers an alternate method of PV module mounting, i.e. third party mounting hardware, it can be arranged so that custom mounting hardware holes can be drilled during production to avoid any kind of field fabrication or modifications.

The DP15 comes in portrait or landscape configurations and can have several different length configurations in order to accommodate any PV strring arrangements that might be needed. Also the different table lengths are very useful in installations with great ground angle variations as they help to follow the terrain as along the installation.
