    But I like my tech. I just wish it didn’t spy on me, and that we had better batteries for solar so that I can use my stuff guilt-free

      It’s possible to have great tech without the spying, but it takes a lot of understanding of and ability with computer technology

      We have pretty good batteries. I have modelled solar on my house (based on records of the 2011 solar array I have), with 15kW of solar panels and many loads (especially HVAC, water heating, car charging) being done in daylight hours I would only need about 10kWh of battery, but 30kWh would be better for a bit of really bad weather tolerance

      The main job of a battery is to provide power between dusk and dawn and to buffer power spikes (like air con starting up) from the solar power, and batteries are well up to doing that

      For reference my normal night time power usage is 6kWh in winter, less when the days are longer

      Lithium iron phosphate (LiFePO4) batteries are safe and aren’t degraded by being charged and discharged daily. Near future battery technologies are less high performing, but are non polluting

      Right tech is rad, just sucks that absolute grosses of people get to decide how all of it works and what it’s used for.
