High-Strength Steel Solar Pile Driven Mounting for PV Farms

The main framework of the Pile Ground Mounting System has two rigid columns, diagonal struts, sloping beams and purlins. Using bolts and nuts, the photovoltaic modules are fixed to the purlins via clamps, which are attached to the structure. All the steel parts are hot dip galvanized after fabrication to guarantee long life corrosion resistance in outdoor. This solution is an excellent response to project requirements in which the land across the plot is rough for a choice of two configurations, the single-column and the three-column choice along with flexible east-west adjustments. It shows excellent value in big size job. The whole Solar Ground Mount Racking system is a perfect match of one single steel pile with the aluminum alloy structure, it has very good performances in high wind load and snow load resistance and greatly enhancing the installation efficiency and minimizing the engineering costs.

1.Installation is quick: the high degree of pre-assembly lightweight brackets the installation efficiency on site, which effectively reduces labor costs and construction period. As a critical operation in pile driving, driving of each pile is only a few seconds of work, especially applicable for big power stations projects with tight schedules.

2.Structural safe: Column as a major load bearing member of the entire Pile Ground Mounting System has very good load capacity and less drilling depth is required for every frame.

3.Strong corrosion resistance: All steel parts are treated with hot galvanizing process, which presents a uniform and compact coating on the surface that could effectively endure the outdoor moisture, salt fog and other kinds of corrosive environments, and enhance the whole service life for the project.

4.Adapt to more Situations of landform: The single/double-column selectable design makes the east-west adjustment possible, which helps to adjust to landforms that are uneven or at slope changes, thus cut down the cost of site leveling, and is greatly applicable to projects like agricultural pv integration, mountainous pv and more.

This Single Pile Ground Mounts system can be used extensively in the following types of solar projects:

1.Ground-based photovoltaic power stations of large size

2.Utility scale photovoltaic power plant

3.Ground solar power generation projects by open sale

4.Solar cell arrays on industrial factory sites

5.Solar arrays on rolling hills

6.Solar-PV farming projects

7.Ground based solar panel systems for commercial buildings

8.Some solar projects designed to minimize the amount of concrete footing work

We focus on those important steps to apply quality control via process as follows:

1. Pre-production raw materials material and size inspection

2. Random sampling check on the size accuracy during the processing of steel parts

3. Test of thickness and smoothness of the coating after hot-dip galvanizing processing

4. Test of fit of mating parts (e.g., bolts and clamps

5. Check off the packing list against the goods prior to dispatching.

6. Final Verification of Project Drawings and BOM List

7. Offere service of installation and technical support for products.

8. What’s more, the structural formwork can be further customized based on the specific load of the project (wind load, snow load, component size, site conditions, and so on), bringing each Solar Ground Mount Racking meeting and exceeding the safety and durable.

We offer custom structural solutions, component package and quotation packages according to the project information below:

1. Dimensions, weight and frame type of solar modules

2. The modules' layout (horizontal or vertical)

3. The size of the project and the design of the string.

4. Location and topographyof the site of installation

5. The parameters of the local basic wind pressure and basic snow pressure respectively

6. The ground soil geological condition or geotechnical investigation report

7. The desired angle of inclina- tion of the design.

8. The pile foundation design depth and pile spacing

9. The minimum distance between the ground and the lowest part of the module

10. Anti-corrosion grade and/or surface treatment

11. Limitations of packaging type and transportation conditions.

The normal installation steps on site are:

1.Verify the project layout, coordinates of the pile position and the foundation depth according to the design drawings.

2.Press the galvanized steel piles into the soil layer with the help of pile driving machinery as per design specification.

3.According to the installation drawings, the verticality, axis and the top level of the single pile is to be adjusted.

4.The penalty columns, the barrier crossbeams, rails (diagonal braces), and the roof trusses are then installed in this order creating a complete support frame.

5.Take end clamps and middle clamps to fix the photovoltaic modules in the rooftop trusses.

6.Full inspection of bolt torque, overall structural alignment and component flatness.

7.Perform final integrated acceptance before delivery of the project. All the parts are pre-assembled in factory and with clear packaging labels, which can bring great convenience to on-site installation and reduce the error of construction caused by mixing parts.
