The cost development of solar is just incredible. We almost doubled the solar capacity on our boat this summer for just couple hundred euros.
For the past year, all of our electricity has come from renewable sources (mostly solar, though we also have small wind and hydro generators on the boat that do contribute when conditions are right). And this includes things like satellite internet, refrigeration, and making all our domestic fresh water through desalination.
We lived off grid in the bush here in Australia on Northern NSW for a decade with a 2kW solar system and batteries, never had an issue, ran everything (computer, kettle, microwave, welder, induction cooktop etc) except for the oven. We left in 2020 because of climate chanhe making bushfires worse and have now moved to Tasmania, off a flood plain, 270m ASL, and zero bush fire risk.
We now have a small cottage on a hectare, on the edge of small village, we have 8kW solar here (so far south solar in winter is an issue) , the excess goes into the grid for which we are paid a small amount and we now have an ecar we need for very occasioanl use (mostly use our ebikes amd walk) , all charged off solar.
