Thanks for the post! Power towers like the solar panel have a area of effect zone around it, think of this zone as your grid that provides electricity for things to run. Solar towers have a small zone where things like the windmills have a much larger zone. Towers like the bees require the power from towers like the solar panel. So "within the power structure" just means the bees need to be placed within the range of the solar panel to be able to work. Also we highly recommend playing in full screen mode for the most immersive experience!
I hope this helps, thanks so much for the feedback and for playing our game! :) And remember, "Weknewables, all of this today, for a better tomorrow."
