Model
Annual EV energy is calculated from distance and driving consumption. Direct PV use and a battery then cover part of combined household and vehicle demand.
Energy · Preliminary estimate
PV, battery and EV
Evaluate household demand, EV charging, PV and storage in one annual energy balance.
ENERGY01
This calculator shows how EV charging changes PV use, storage demand, grid import and export.

Results
PV + load + storage
Complete the inputs and calculate.
Scope
Vehicle availability, charging power, seasonal generation and the actual charging schedule can materially change the annual balance.
Assumptions
Inputs, units and assumptions remain traceable in the result. Planning and approval require measured data, manufacturer documentation and a time-series simulation.
