check out this map. i can easily power an entire industrial base with solar + batteries.
and this isn’t an “easy” (beginner) level either. This is Overgrowth (enemy base, threat level: high). I’m 12 waves in and fine.

as you can see in the minimap, most of the map is still empty. so i could easily build much more. but it’s not needed. the idea that “solar power generates little energy” (only 7 power / tile under full sunlight) is not actually hindering you from using it in mass-scale. Because basically any map has a lot of unused free space anyways.
It uses a lot of silicon. It’s more about how much solar power delays your tech tree. In survival & multiplayer stuff is only useful for filling the occasional square. I wish large panels were actually useful.
Not to mention space efficiency is very important for concentrating defenses & overdrive bubbles
oh btw in case anyone wonders why i don’t have an air factory or sth: i use pyratite guns to burn down the enemy base. so i shoot with ripple and swarmers (those are fun) into the enemy base and burn it all down. that’s why there’s nothing on the map on this big empty spot that i’ve already taken.

this is what i mean
Just because you can doesn’t mean you should…
