See how solar panels, a home battery and an electric car share energy through the day and night. Choose a stage below, or use the arrow keys.
While the sun is up, the panels power your home first, so you buy less electricity from the grid.
Whatever the home doesn't use right away is stored in the battery instead of going to waste.
In the evening, the stored solar energy keeps the lights and appliances running.
Plug in the car and charge it with sunshine from your roof, saved in the battery.
