Interesting mechanic. Could have used a tutorial on what to do. Unless I'm doing it correctly already. I've bought solar panels, and I'm aligning it(I guess that means clicking on the thing that turns red?) Some times the sun indicator gets stuck at the end.
I'm also unclear on the icons on the left and what they mean (except the top one)
It takes kinda long for me to buy something new and nothing to do when its dark, unless I am missing something.
