if it works in germany, czech republic, poland which is higher latitude than 99.99999999% of USA or 80% of canada population then it will work even in USA too. Again read my first post, it is NOT about reaching 100% offgrid which is expensi

PV + heatpump maybe. PV + resistive heater yes. solar thermal is not worth price wise. solar thermal can be feasible only for big installations as is in stralsund, leipzig... - megawatts. solar PV is order of magnitude cheaper in small syst

efficiency of no MPPT is around 10 percent lower then with MPPT system so no issue. 2000 watt is maybe max what you can have on balcony - physical size, and 2000 watt inverters are like 20 $. well connecting anything to grid is/should

well just piping for hot water system is more expensive then PV panels. But biggest expense is instalation costs(humans) so it depends how you calculate. But PV system can be used for hot water, tv, car, charging kids bikes, lawnmower etc.

Yeah that too, but that has limits, for example european union regulates building industry in such way that every new build, rebuild has to be done in a way that your heating energy requirement is already lower than your hot water energy re

In Czech republic - europe - they made law that says anyone can built up to 100 kWp solar array, without any building permits, township meetings, HOA nonsense etc. You want it, you can build it. Best way to be independent of your neighbors

Why invent wheel when we already have Reticulum network which provides integrity and confidentiality on OSI Layer 2 ? So for every packet. It is not better to build "apps" on top of a secure network? That way even if "app&quo
