Energy & ROI Modelling
We model the full financial picture of a commercial solar investment: capital and operating cost, self-consumption versus export, the value of capital allowances, and payback under your actual tariffs and half-hourly load.
A headline 'six-year payback' means little without the assumptions behind it. We build the model around your actual half-hourly consumption, your current and forecast tariffs, and a realistic view of self-consumption versus export — then layer in maintenance, inverter replacement and panel degradation across the system's life.
The tax position matters too. Modelled net of the capital allowances available to your business — such as the Annual Investment Allowance and Full Expensing — the real payback is often better than the sticker price suggests. We hand you the model, the assumptions and the scenarios, so finance can interrogate every line.
What it delivers
- Half-hourly load-profile analysis using your own metered data, not sector averages
- Self-consumption vs export split modelled against current and forecast tariffs
- A capex/opex model with maintenance, inverter replacement and degradation built in
- Corporation-tax treatment — capital allowances such as the AIA and Full Expensing — reflected in the net cost
- IRR, NPV and payback under base, upside and downside scenarios
Outcomes
- A transparent model you own and can stress-test
- Capital-allowance value captured, not left on the table
- The confidence to approve — or reject — on the numbers
Frequently asked questions
Do you use our actual energy data or industry averages?
Your own half-hourly consumption wherever it's available — averages hide the daytime-load detail that determines self-consumption and payback.
Can you reflect capital allowances in the numbers?
Yes. We model the net-of-tax cost using the capital-allowance treatment available to your business, such as the Annual Investment Allowance and Full Expensing, so the payback reflects what you actually pay.
