I liked the idea of this when I saw it on the game suggestions threads… instead of messing with the generator at all… cause best not to mess with original stuff so every update doesn’t break your mod… do like some of these said “batteries” work it like the water things… day light fills the batteries… and night drain battery at x amount/hr which means to power through the night you would have to have x number of batteries and being they are expensive you might still have to use gens for awhile but eventually completely replace the need for gasoline. and if you wanted to go a step farther you could make the panels only generate x power/hr each so to charge the batteries to full 100/100 (100 is 1 hr of night power) you need 2 panels per battery… just an idea.
