What is this tool used for?
Use this tool to estimate the solar energy and panel count associated with your daily electric-vehicle driving, plus charging time at a chosen charger power.
How to use this calculator
Enter daily kilometres, vehicle battery consumption per 100 km, charging efficiency, peak sun hours, solar losses, panel wattage and wall charging power. Vehicle consumption should exclude charging losses because the tool adds those separately.
Understanding your results
Panel count is an energy-equivalent requirement, while charging hours use your chosen wall power. Sufficient daily solar energy does not ensure the array can supply the charger's instantaneous demand; grid support or storage may still be needed.
Spôsob výpočtu
Pred použitím výsledku
Vehicle consumption should exclude charging losses because efficiency applies them separately. This is an energy balance; charging at the chosen power may require the grid or storage even if daily solar energy is sufficient. Charger minimum power and vehicle limits need separate checks.
