The Solar Panel is an Minion Fuel unlocked at. It can be used to speed up a Minion by during the day when placed inside the Minion Fuel Slot in the Minion GUI. 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.

Day Saver
Using it in addition to a 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 increase in minion speed when the player is not around.

It might be better than the if one has a Day Saver and an alternate account that is constantly AFK on the island as it will then give a  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.
