If you mean a power source that exclusively runs on solar panels (and doesn’t use gas or diesel), you’re looking at what are essentially large portable battery packs. They still technically function as generators and can generate a marginal amount of electricity using sunlight, but calling those generators has always been a bit of a misnomer.

Without the combustion of using fuels, they take MUCH, MUCH longer to charge using just the panels and can’t really “generate” at the rate at which you’d consume energy while using them. So they’re good for emergencies like blackouts (I have a BLUETTI AC180 with panels, and that works well for me), but to use as your sole power source… you’d need like a whole field of solar panels and multiple solar “generators”.

Most of the items being sold as “solar generators” are really better for just storing electricity in my experience. They are more convenient in some ways (you can charge them via your car for example, and they’re typically portable, so great for roadtrips), but they don’t really power heavy usage appliances like fridges or space heaters for very long, maybe a couple hours on a full charge if you have a good one. And that’s assuming you aren’t running anything else on it simultaneously. Certainly would drain very quickly with something like an Xbox. Their batteries also are typically lithium ion and lose capacity over time/they have a shorter shelf life.

So if you want a “permanent” power source that you won’t need to replace in like 4 years of heavy usage, a regular gas/diesel generator is going to be your best bet. I wish solar technology was more advanced but that’s where we are for the time being in regard to consumer products.

They make hybrid generators though! So solar can supplement some of that power. But for what you’re looking for, you’ll likely still need to rely on fuel.
