To progress from pre-feasibility to bankable assessment, these studies are typically required:
| Study | Duration | Purpose |
|---|---|---|
| Satellite irradiance validation | 6–12 mo | Ground pyranometer data for model calibration |
| Soiling & degradation study | 6–12 mo | Measure site-specific soiling rates & cleaning plan |
| PV module flash testing | 1 mo | Verify nameplate STC rating of selected modules |
| PVsyst / SAM detailed design | 1–2 mo | 3D shading, string layout, inverter clipping analysis |
| Geotechnical survey | 1–3 mo | Piling / foundation feasibility, drainage |
| Grid connection study | 2–6 mo | POC assessment, capacity, export cable |
| Environmental & Social IA | 6–18 mo | Permitting, glare, ecological, community |
| Land lease / acquisition | 3–12 mo | Surface rights, access, community consent |
| Bankable yield assessment | 2–3 mo | Independent P50/P90 by accredited consultant |
