Optimising how Sunne harvests energy

Sunne charges best in full sunlight. So, when you select a window to hang Sunne - best is to choose a southerly orientation with minimal shading obstructions (avoid trees and tall buildings).

Temperature is also an important factor - some windows get really hot - and we suggest not to hang it directly against the window. Above 45 degrees Celsius, the charging performance is limited for safety reasons. So if you see a lot of sunlight shining on Sunne, but it is not charging well, check the temperature.

If at one point the battery is empty and there's not enough sunlight available, you can always charge Sunne using a USB-C cable. Just plug it in to the USB port next to the button.
