More creative use of parts but I was able to have the bowling ball ricochet off of motors to hit a match to permanently keep the solar panel going compared to your official solution.

Also, writing text and using arrows to point to what needs to be activated would help players see what can be used to deter ghosts. I was thinking something along the lines of a parts creator hidden somewhere. I didn't even see the pinball bumpers and Zoe's camera behind the partially transparent scenery until I triggered the off screen dynamite.
