PEG System CAPEX Savings Highlights:
The PEG’s design simplicity and lightweight substructure are the system’s key characteristics. The steel bars and plates are made of hot-tip galvanized steel bars with ground and top plates, on which the PV modules are installed.
1.) Budget Overrun Risks
With no foundations, concrete, DC trenching and heavy machinery, and with minimized labor usage, and lightweight substructure, there are far less cost overrun risks compared to the installation of other substructures.
2.) Labor Efficiency
The installation process is highly streamlined minimizing the amount of labor needed to install the DC system to approximately 460 person-hours per MWp with 550 watt modules. This positions the PEG as a strong candidate for unionized or high cost labor markets. Given the simplicity of the mechanical install low the use of skill labor is another contributor for the CAPEX saving.
3.) Material Costs
PEG was re-designed from the ground up. Instead of heavy steel posts, many lean rods are used. The PEG design saves approximately 75%+ of steel compared to conventional substructures.
