Hello! I'm still a little bit new to how No Man's Sky works (I have about 60 hours logged but over half of that is grinding, lmao) so I have a question or two. One, I found and fixed a sentinel ship, are those any good long term? Two, if my base is having energy problems, do I need to add more batteries or more solar panels? I'm using like 350V and making 375V. Three, if my new settlement is on an extremely toxic planet, the collective happiness is at 12%, and everyone is in a near constant panic at the storms, should I just, like, ditch them? Is that colony worth it? It's dragging itself out of debt like a corpse from a grave, but progress is being made.
The interceptors are very nice, especially once you have them fully levelled up to S class and with complete sets of S-class technology augments. Also the ability to hover at 0 airspeed is really nice when you're, for example, on a mission that only brings you to the 'approximate location' of a goal - you can come to a stop in mid air and do slow spins to try and spot your goal by eye instead of having to run around on the surface or making short surface hops to get to it. I tend to grab the first one I find, use it without levelling and with mainly augmenting the cannon and shields, at least until I find one I like the look of. At that point I can swap the technology to the new ship and salvage the old one.
Sounds like you probably need at least one more each of solar panel and battery. You want to have sufficient production to fill enough batteries to last through the dark, if you haven't built in range of a power hotspot. For a small base that only has a few powered lights and a portal hooked to a proximity switch (so it's only running when you're close to it), one solar panel and one battery is more than enough. For a mining base with a mineral and/or gas extractor, I generally aim for about 3 each of panels and batteries per extractor plus at least one more for the base's lighting/portal. For extensive bases, especially ones using powered base modules, always try to locate them near a power hotspot. or you will need so many panels and batteries.
The settlement's debt situation will improve over time as you make settlement/building decisions, but the extreme weather (especially if it storms frequently) combined with sentinel attacks can get very annoying for you as the player (why yes the first couple of times I claimed settlements they were on extreme planets, why do you ask...). I'd definitely recommend keeping an eye out for a planet with mild weather (and aesthetics you like) and starting over with a settlement there instead. You do have to pay to switch, iirc it's based on the race of the system and will be the rarer of the two racial collectibles (so geknip, convergence cubes, or daggers). I think it was two or three of them? It's been a while :)
Have fun, and feel free to ask more questions!
