battery or solar pannels

[Rockefeller]

i havent used the solar panels but only adding +30 power a minute per panel seems kinda crappy. you're better off using the limited power cores to upgrade your battery capacity and use the fission reactor to make up any shortfalls when you need it. by the end of the 'game' i had a capacity of 3500 power which lasts a very long time.

Solar cells are of little help here. The train moves mainly in the shade, among high rocks, and the solar cells do not work there.

3 solars are great as +180 power + 50 basic regen = 230. This means that you can stop train and shot drones, loot them and regen train in meantime. If you combine it with nuke power and dynamo (1 material to fix 80HP. with 20-100 power mini game) it is quite decent mixed power regen.
This makes you 2-3 battery left when you go to Dome.

On hard things are a bit different due to drone damage and amount of drones. Three batteries is all you need on easy and medium. But on hard you need both generation and storage. Three batteries plus a dynamo and if your luck with drone drops, a solar panel or two
