Illustrative scenario.
An example under stated assumptions. It helps explain a decision and does not show an achieved customer result.
FIGURES & EVIDENCE
Know what a number
does and does not say.
Useful decisions start with a clear basis. Our tools show illustrative scenarios; a proposal needs your actual site information and the complete costs.
| Tool | What it answers | Basis and limits |
|---|---|---|
| Reference calculator | How does a stored comparison scenario change with solar and battery size? | September 2026 reference dataset. Interpolation between values; home solar above 12 kWp is extrapolated. Includes modelled trading. Before capital, finance and service fees. |
| Detailed energy model | How do energy costs change under the entered operating assumptions? | 8,760-hour simulation, synthetic demand and a published tariff snapshot. Includes entered export tariffs. No additional wholesale or flexibility payments. |
| Fleet charging planner | Does the total required energy fit the shared power and time available? | Energy divided by power and efficiency. A common charging window, constant power and no vehicle-level tapering. A capacity check, not a charging schedule or savings forecast. |
READ FIGURES IN CONTEXT
Three different
types of evidence.
Measured outcome.
Operating data compared with a defined baseline, period and scope. The basis should accompany any published result.
Commercial proposal.
A site-specific assessment that sets out equipment, full costs, responsibilities, operating assumptions and terms.
Sources behind the detailed model
The detailed model uses a solar profile based on European Commission PVGIS data and an August 2026 Octopus Flux tariff snapshot for region E. Rates are editable and the snapshot is not an available tariff offer.
- European Commission: PVGIS methodology
- Octopus Energy: Flux tariff and eligibility
- Ofgem: Smart Export Guarantee

Neither tool supplies evidence of nodez. operating performance. Outputs from the two energy models are alternatives and must not be added together.
