The Solar Panel is an UNCOMMONMinion Fuel unlocked at Nether Quartz IX. It can be used to speed up a Minion by 25% during the day when placed inside the Minion Fuel Slot in the Minion GUI ( Orange Glass). Unlike most other fuels, it has an unlimited duration. It is not consumed and will be returned when clicked or a minion is picked up.

Daysⓘ to acquire 30,720xNether Quartz using a Quartz Minion (By tier, No fuel, No Minion Upgrades) If the player has multiple minions, divide the number of days by how many minions will be used.
Using it in addition to a Day Saver will cause it to run permanently.
However, the Day Saver does not work when the player is offline; thus, the Solar Panel effectively provides a ~12.5% increase in minion speed when the player is not around.
It might be better than the Enchanted Lava Bucket if one has a Day Saver and an alternate account that is constantly AFK on the island as it will then give a 25% boost to minion speed. The Day Saver can be considerably more expensive than an Enchanted Lava Bucket due to an extremely high Bazaar cost, in which case the Enchanted Lava Bucket is a more preferable option.
