This mod is made with Mcreator and can be used with others energy mods as Thermal
Although I design Powered Spawner to use it with another energy mod, it contains a solar panel.
For the crafting recipes I advice you to install JEI
Each spawner needs 50k, 100k or 250k FE to spawn 4 mobs, the animals/monsters spawn only if they have the space.
You can stop the spawn with redstone signal
