poVoq linked an article from Low Tech Magazine, which is a great resource for low energy sustainable living. I wanted to highlight this older article from them, too:

It's not clear to me, from your post, if you're thinking about making a home/apartment "off grid", and limiting your powered appliances to what solar power can cover to prepare for future disruptions to the power grid, or about living outside a fixed dwelling and using portable solar to power a few accessories like a portable induction stove. This matters because solar panels are bulky and batteries are heavy - charging a laptop and phone is trivial with a man-portable setup, but a solar generator capable of boiling water and cooking is not going to fit in a reasonably sized backpack 😆

If you're thinking about "bugging out" or "going off the grid" in the survivalist sense, living with only the equipment you take with you, you might get better answers on equipment from camping and survivalist forums.
