Model
LCOE includes investment, maintenance, degradation and discount rate. Simple payback compares investment with annual value from avoided imports and exports.
Energy · Preliminary estimate
PV payback and LCOE
Combine investment, operating cost, degradation, self-consumption and export revenue into LCOE and payback.
ENERGY01
LCOE means levelized cost of energy: discounted lifetime cost divided by discounted lifetime electricity generation.

Results
PV + load + storage
Complete the inputs and calculate.
Scope
Financing, taxes, inverter replacement and tariff changes must be represented with explicit inputs or scenarios.
Assumptions
Inputs, units and assumptions remain traceable in the result. Planning and approval require measured data, manufacturer documentation and a time-series simulation.
