EV & Solar Charging Calculators

Size solar panels for EV charging, match your home charger to solar output, calculate V2H backup runtime, and compare solar-charged EV vs petrol.

Compare charging costs vs petrol or diesel, with per-mile and annual savings.

Realistic range estimate accounting for speed, temperature, terrain, and driving style.

Real 5-year cost: purchase, fuel, maintenance, insurance, depreciation for EV vs petrol.

What will it cost to install a Level 2 EV charger at home? Panel, wiring, distance, permits.

Plan your EV road trip — charging stops, drive time, and total trip duration.

How many solar panels does it take to charge your EV? Enter daily driving distance and panel specs.

Size a single solar system that powers both your home and your EV. One roof, one system, two loads.

Your EV has a 60-100 kWh battery. How long can it power your home during an outage or loadshedding?

True EV payback when you charge with solar vs grid vs petrol. The solar-charged EV often wins by $10k+.

Match your EV charger power to your solar output. Level 1, Level 2 (7.2kW), or Level 2 (11.5kW)?
