Find the capacity your current layout is leaving inside the fence.
Most utility-scale projects lose capacity in the very first layout, and the loss is locked in long before anyone thinks to check. It is cheap to fix on a drawing and expensive to fix on site.
This is not a checklist review. The audit rebuilds a reference layout of your site, runs an independent yield model and takes off the quantities, then compares all of it against your design — a row pitch cannot be called too conservative without something to measure it against. You keep that reference design. Every audit is carried out by the founder and lead engineer directly: nearly a decade in solar PV design, 1 GW+ designed across 15 countries.

Turnarounds are maximums in working days, counted from the confirmed start date rather than from your first email; delivery is usually sooner. One audit runs at a time, so the start date is the thing worth booking early. Extended adds a second engineered layout variant and a capacity and quantity comparison — technology and orientation trade-offs belong in a Comparison Study.
An advisory memo, not stamped design documentation. AC and grid studies are quoted separately through a vetted partner network. NDA before you send anything, on request.
What You Send
- Site boundary and any topographic or constraint data
- Current layout — DWG, PDF or PVcase export
- Equipment selection, if already fixed
- Grid connection capacity and TSO conditions
- Target COD and project stage
Incomplete is fine. Part of the audit is telling you what is missing.
What You Get Back
A Reference Design of Your Site
An independent layout, yield model and preliminary bill of quantities, included in the memo as drawings and figures. Editable files are released with any design package you book.
Capacity Findings
Usable area, row pitch, GCR and module count against what the site actually supports.
- Usable vs. constrained area
- Row pitch and GCR for the latitude
- Setbacks and exclusion zones
- Inverter, MV station and access road placement
Yield Findings
PVsyst assumptions, shading and loss modelling, and where P50 is likely to move.
- Meteo source and shading model
- Soiling, mismatch, thermal and cable losses
- DC/AC ratio and clipping
- Degradation and P50 / P90 treatment
Buildability Risks
- Access roads
- MV station siting
- Trench corridors
- Setbacks
- Land drainage
- 3D terrain *
Quantified Deltas
In engineering units: MWp inside the same fence, module count, trench metres, P50 %. You apply your own cost rates.
Prioritised Recommendations
Ranked by the size of the delta, not by how interesting they are to engineer.
* Drawn so it carries straight into FEED — trench runs take minor adjustment at detailed design, not a redraw.
How It Works
Send What You Have
Site boundary, current layout (DWG, PDF or PVcase export), equipment, grid capacity and target COD. Incomplete is fine.
Scope Confirmed
Size tier, package and start date confirmed by email within one working day. No meeting required; NDA first if you need one.
Reference Design
An independent layout, yield model and quantity take-off for your site. If nothing is worth acting on, you hear it at this point and do not pay.
Findings Memo
Every finding in engineering units, ranked by size, with the reference design included as drawings and figures.
