Hi Lavie, I came across images of your apartment in your previous posts and I think you did a great job in decorating and maximizing the space.
We had a 9 cubic meter concrete tank and a pressure pump with a built-in tank. Since there is no electricity connection in the area, we have a generator to run it and for minor electrical use like charging phones or connecting power tools.
We wanted a solar panel system for it all but decided to delay doing so since we don't use the space often. After comparing costs between having the main electricity connected (due to the distance from the main power line) and installing solar, solar appeared to be more economical in the long run because of the cost of connection. A hybrid solar system is better though.
I can't believe it's the weekend already. Have a great one too!
