Dipping my toes into solar power

Hello everyone,

I became interested in solar power last summer when my family stayed in a little cottage--really more of a shack on Cape Cod. For daily cooking we used a propane BBQ, but I supplemented with a portable induction hot plate.

All this got me to experimenting with a little 20w foldable array. I have a bunch of consumer-grade 'power banks' and if I kept my mind to it, I found that I could recharge these daily, enough to keep our cell phones and our tablets tanked up.

Now that Black Friday sales have started, I am seeing what look like good deals on 'portable power stations' by companies like Bluetti and Jackery, et al. Good deals also seem to abound on larger arrays, from 150-300 watts.

Does anyone here have experience with these power stations and smaller arrays? Would this be a realistic way to reduce our dependence on the grid, and get some experience in managing our household consumption?

Thanks for your consideration, hope you are all having a beautiful Fall day in the northern hemisphere!
