I live on an island and my first priority after getting a full time job again is to buy solar and storage good for a few days of my homes usage. The cost of energy is increasing here and I don’t see it ever going down since we’re still using oil for the most part. I plan to build a little wood workshop shed in my yard and cover it with solar panels and put some batteries in it. I should only need about 30 kWh of storage to cover three days use, and maybe 2 or 3 kW of panels for daily use and recharging the batteries; except for the EV, which I normally charge once a week but I can just start plugging in during the day instead. With that setup I can keep connected to the grid and eventually see if I can go off grid after a few years, or possibly add more solar and storage later if I find the first phase wasn’t enough.
However, that’s only possible because I have money and knowledge; most people don’t have that and so as a whole we’re kind of screwed here. Costs will continue to rise while not enough renewables are installed, usually on individual homes which only helps those individuals.
