==Trivia==
+
* The solar panel counts sunny days based on the location it is placed. Thus, a solar panel placed down on [[Ginger Island|Ginger Island]] will not be affected by rain in Stardew Valley, and vice versa.
+
** This can be seen most clearly in [[The Desert|the Calico Desert]], where there is never rain even if there is rain in the rest of Stardew Valley. As such, solar panels placed in the Desert will always produce a battery pack every 7 days.
