Before you progress

  • Obtain interval solar export and consumption records.
  • Confirm tariff, battery warranty, degradation and installed quotation.
Assumptions & limits
  • Declared two-window day replayed through PV8 load matching; not a measured annual dispatch study.
  • Inputs are unverified. EUR only; no automatic currency conversion or jurisdiction-specific entitlement is inferred.
  • Constant year-end pre-tax unlevered cash flows. No inflation, degradation, financing, tax, replacement or terminal value. Payback is not a return guarantee.
  • An identical declared day repeats for the entered operating days. Each day starts empty; residual stored energy is not credited. No grid arbitrage, peak-demand savings or ancillary-service revenue.
