MECHANICAL DETAILS

The mechanical construction is a critical aspect of utility-scale solar energy projects. It involves the installation of the racking system, which is responsible for securely mounting the solar panels to the ground. Here is a detailed overview of the various aspects of mechanical construction as they pertain to a utility-scale solar energy project:

​

• Site Preparation: Prior to the installation of the racking system, the site must be prepared by grading the ground and preparing the foundation. This involves the installation of pile driving, which involves driving steel piles into the ground to anchor the racking system.

​

• Racking System Installation: The racking system is responsible for securely mounting the solar panels to the ground and keeping them in place. This involves the installation of a range of components, including vertical posts, horizontal rails, cross-bracing, and attachment brackets. The racking system must be designed to withstand high winds, heavy snow loads, and other weather conditions.

​

• Torque Specs: The racking system must be installed to specific torque specifications to ensure that it is secure and will not come loose over time. This requires the use of specialized tools to tighten bolts and other fasteners to the correct torque specifications.

​

• PV Panel Installation: Once the racking system has been installed, the PV panels must be mounted to the racking system. This involves the installation of attachment brackets, which hold the PV panels in place and allow for easy adjustment.

​

• Wiring: Once the PV panels have been installed, the wiring must be installed to connect the panels to the inverter and transformer. This involves the installation of conduit, cable trays, and other components to route the wiring from the panels to the inverter and transformer.

​

• Commissioning and Testing: Once the racking system, PV panels, and wiring have been installed, the system must be commissioned and tested to ensure that it is functioning correctly. This involves a range of tests, including insulation resistance tests, ground resistance tests, and polarity tests.

​

• Ongoing Maintenance: The racking system, PV panels, and wiring must be maintained on an ongoing basis to ensure optimal performance and compliance with local regulations. This includes regular inspections, cleaning of the PV panels, and replacement of worn or damaged components.

​

In conclusion, the mechanical construction is a critical aspect of utility-scale solar energy projects. It involves the installation of the racking system, which securely mounts the PV panels to the ground and keeps them in place. The racking system must be designed to withstand high winds, heavy snow loads, and other weather conditions, and must be installed to specific torque specifications.
