Verified energy baseline
We work from 4 to 12 months of actual electricity bills rather than assumptions, and establish the applicable tariff and load pattern.
- Bill capture and validation
- Tariff structure confirmation
- Load factor and offset targets
Yield modelling (P50 / P90)
Production is modelled per array using irradiation data referenced to PVGIS, with orientation, tilt, shading and losses applied.
- Per-array orientation and tilt
- Shading and system losses
- P50 and conservative P90 cases
Financial model
A 20-year cash flow with escalation, degradation and operating cost assumptions, reported on the metrics reviewers ask for.
- IRR, NPV and payback
- DSCR by year
- Sensitivity to tariff and yield
Tax treatment
South African renewable energy capital allowances are modelled explicitly so the after-tax picture is visible.
- Section 12B / 12BA allowances
- After-tax cash flow
- Effect on payback and IRR
Compliance evidence
A checklist of the approvals, standards and documentation typically required for grid-tied commercial systems.
- SSEG and utility requirements
- Standards and CoC evidence
- Structural and safety sign-off
Assumptions register
Every input is documented and sourced so a reviewer can test the model instead of guessing at it.
- Input source and date
- Ranges and confidence notes
- Version-controlled outputs
Feasibility and bankability studies are advisory engineering and financial modelling work. Modelled savings and returns depend on the assumptions listed in each report and are not a guarantee of future performance or of funding approval.
Commission a feasibility study
Send us 4 to 12 months of electricity bills and your site details, and we will scope a feasibility study or produce an indicative model first.
