Son, son, son, you gotta step up your battery game man where's your capacitance? I see you were trying to get it smoothed out in later cycles but you need way way MOAR. The battery bank must grow.

All my solar factories are a never ending balancing act of expanding about a continents worth of panels and batteries as needed. Its not a bad idea to have the fuel burning steam engines on grid as backup while you get energy completely figured out.

1. Automate panels + batteries+transformer poles

2. set up a robot construction network grid then create two blueprint variants that fill up a big transformers poles worth of batteries or panels

3. copy/paste over a vast area of desert thats we aquired from the natives through 'advanced civil forfeiture techniques'.

This will serve you well enough until your production energy demands scaling become so rediculous that pasting acres of solar on a continental level no longer becomes a viable solution. At that point you swallow your hippie pride and figure out how nuclear reactors work.
