EPC — Engineering, Procurement and Construction — is the turnkey delivery of a solar project, from design through supply to commissioning. This guide explains the stages and where engineered structures fit.
Key takeaways
- EPC covers engineering, procurement and construction end-to-end.
- Structures are a core part of the balance of system.
- Compliance (ALMM modules, IS-standard structures) runs through procurement.
- Documentation supports acceptance and warranty.
The EPC stages
Engineering fixes the design to site conditions and standards; procurement sources compliant modules (ALMM), inverters and structures; construction installs, tests and commissions the plant.
Where structures fit
Mounting structures are a core part of the balance of system. Matching the structure, coating and foundation to the site is what keeps an EPC plant reliable for its design life.
