Phase 6 of 8 — Consultancy Process
Design Review & Verification
All EPC engineering designs, single line diagrams, and structural calculations are audited against IEC standards prior to construction commencement.
Preventing System Faults at the Blueprint Stage
Even after a skilled EPC contractor is contracted, their detailed mechanical and electrical drawings must never be assumed to be flawless. Incorrect tilt angles, miscalculated azimuth orientations, undersized DC cabling, and sub-optimal stringing design routinely cause invisible energy losses, excessive voltage drop, and electrical safety hazards.
Before any equipment is delivered to site or physically installed, PV Consultants executes a mandatory engineering design verification. Drawing from decades of designing utility-scale systems across the Middle East (including Saudi Aramco repeater stations and major telecom expansion projects), our certified team reviews every diagram with rigorous precision.
Comprehensive Design Audit Areas
- Electrical Single Line Diagrams (SLD): Forensic review of combiner box connections, AC/DC disconnection switches, inverter fusing, and busbar ratings.
- Voltage Drop & Power Loss Calculations: Verifying wire gauge sizing over long cable distances to ensure operational energy loss remains strictly below industry tolerances (<1.5%).
- String Configuration & MPPT Balancing: Checking open-circuit voltage (Voc) coefficients under localized winter temperature extremes to prevent inverter overvoltage trips.
- Earthing & Lightning Protection Architecture: Auditing grid grounding meshes, electrode pit calculations, and Surge Protection Device (SPD) coordination against lightning discharges.
- "Approved for Construction" Certification: Issuing formal engineering sign-off on drawings once all structural, electrical, and safety non-conformities are corrected by the EPC.
Do It Right The First Time
Overlooking engineering discrepancies on paper means paying for costly physical retrofits, facility downtime, or permanent daily yield reduction once the plant is live. Our independent design review guarantees that your solar installation is built upon flawless technical engineering from day one.
