This checklist sets out the engineering areas covered in an independent design review of a utility-scale solar PV plant, from energy yield and technology selection through electrical, civil and structural design to grid connection and constructability. It is derived from SgurrEnergy's engineering, design review and owner's engineering scope, and helps confirm a design is complete, compliant and constructable before it is issued for construction.
Energy Yield and Technology Selection
Confirm the production estimate and equipment choices are sound and consistent.
- Resource and yield basis
- Module selection and bankability
- Inverter selection and ratio
- Tracker or fixed-tilt choice
- Performance ratio target
Electrical Design
Check the electrical design from array to point of connection.
- DC system design
- AC and MV collection
- Earthing and lightning protection
- Protection and metering
- Losses and voltage drop
Civil, Structural and Site
Confirm the design suits the ground conditions and site constraints.
- Geotechnical basis
- Structural loads
- Grading and drainage
- Roads and layout
Grid Connection and Constructability
Verify the connection design and overall constructability.
- Grid connection design
- Grid compliance studies
- Constructability and sequencing
- Drawings and specifications complete
- Standards and compliance
