Solar PV · BESS · project finance

Solar and BESS financial model build and review for African projects.

Build, review or stress-test the commercial and financing logic behind utility-scale and C&I solar, battery storage and solar-plus-storage projects. I can review an existing model or build the missing finance layer around a live investment decision. Best suited to developers, investors and advisers who need an auditable model or an independent second review before a financing or investment decision.

SEND MODEL BRIEF CHECK PROJECT FIT

Model purpose

A model should answer a financing question, not just calculate returns.

I structure modelling work around the decision the project team, lender or investor needs to make. Assumptions are traced through revenue, operating cash flow, debt service and equity returns, then tested under downside cases.

The result is easier to review, explain and use in management, lender and investment conversations.

Commercial fit

Use this when a live model needs a decision, not just a spreadsheet clean-up.

Typical fixed scope: US$1,500 to US$3,500 · usually 5–10 working days.

Existing model review

Trace assumptions into CFADS, debt service, returns and downside cases, then isolate the issues that can change approval or financing.

Model build

Build a transparent decision model where the project team has technical, commercial and financing inputs but no reliable integrated case.

Overflow capacity

Take a defined modelling workstream when the internal investment, finance or development team is temporarily stretched.

Fast screen

If a full model review is premature, start with the smallest useful project screen before committing more time or advisory budget.

Model modules

What the analysis can cover

Built or reviewed to match the project stage.

Revenue

Generation and tariff

Energy yield, degradation, availability, curtailment, PPA tariff, escalation and residual revenue where relevant.

Costs

CAPEX and OPEX

EPC cost, development cost, contingencies, OPEX, land, insurance, replacement costs and escalation.

Debt

Debt sizing and repayment

Debt quantum, tenor, interest, fees, repayment sculpting, CFADS, DSCR, LLCR and covenant headroom.

Reserves

Cash waterfall and accounts

DSRA, maintenance or replacement reserves, restricted cash, distributions and lock-up logic where required.

Storage

BESS assumptions

Capacity, duration, efficiency, degradation, cycling, augmentation and storage-driven revenue or cost effects.

Returns

IRR and downside cases

Project and equity returns and sensitivities to tariff, yield, CAPEX, OPEX, debt pricing, delay and combined stresses.

Examples

Public examples show the logic without exposing private project data.

Model QA

What I test when reviewing an existing model.

Are key commercial assumptions visible, consistent and traceable?
Does the debt schedule reconcile to CFADS and covenant logic?
Are reserves, fees and distribution restrictions treated consistently?
Do storage, curtailment, degradation and availability assumptions flow through revenue realistically?
Do downside cases expose the assumptions that genuinely threaten bankability or returns?
Can another analyst understand the model without reverse-engineering it?
