FINANCIAL MODEL
A photovoltaic project financial model projects the economic life of the asset over its whole operating period: generation, revenue, costs, debt, taxes and valuation. Wattvalio builds it for you — consistent, auditable and recomputed in real time.
P50/P90 yield and degradation, price (feed-in, PPA, market), staged CAPEX, OPEX, inflation, taxes, discount rate.
Revenue − OPEX = EBITDA, then depreciation, interest and taxes down to net income.
From operating cash to debt service, down to the cash distributable to the shareholder.
Drawdown, amortisation (annuity or sculpted), interest, DSCR, LLCR and covenants.
Project NPV, NAV by sum-of-the-parts, rate by risk profile, valuation bridge.
A photovoltaic asset is held by a project company (SPV), often owned by a holding. The financial model must then consolidate: dividend up-streaming, shareholder loans, corporate debt and share sell-downs. To estimate returns quickly, use the solar ROI calculator; for the software itself, see the solar business plan software.
Three consistent statements — income statement, cash flow statement and financing/debt plan — driven by assumptions (P50/P90 yield, price, CAPEX, OPEX, taxes) and leading to the metrics (IRR, NPV, DSCR, LCOE) and the valuation.
Debt is sized on the project's ability to repay it: you target a DSCR (often 1.15 to 1.30×) by amortising the debt as a constant annuity or as a sculpted profile that follows the cash flows. Wattvalio computes these profiles and ratios automatically.
Yes. The model rolls up to the holding level: SPV dividends, shareholder loans, corporate debt, intra-group eliminations and share sell-downs — for an auditable consolidated NAV.
Isolated versions, audit trail, figures justifiable line by line.
