    > being about 20%

    we're up to 33.2% now, just need to ramp up production [1]

    > I'll admit that spending 5K$ for 6kWp is not that sexy

    I think you can do better for $5K if you source your panels used from the commercial industry, cc @SlicerDicer who can give advice

      The PV scientific community’s rush to the latest efficiency record
      from pv magazine
      Perovskite-silicon tandem technology expert Gianluca Coletti explains what cycles the PV industry and scientific community experience every time there are new jumps in power conversion efficiencies at cell level. According to him, we are experiencing a much faster turnover of efficiency records typical of the early stage of development of a new technology holding an incredible potential.

      @neauoire you're pushing the limits here 🙂

      regarding some comments about PV efficiency being about 20%: are we goint to ditch photosynthesis because it's ~1% efficient? efficiency, in this case, means just that we're not using large parts of the spectrum exactly as if we weren't doing anything. it's not like the ~40% eff of an internal combustion engine in which we have 60% heat output and toxic/greenhouse emissions.

      so if somebody has a large roof, install as much PV as you can and be 100% self sufficient. it's so cheap today.

      of course living on a boat puts you in a special position and I enjoy your experiments! ;-)

      I just don't wanna see people saying that PV is bad because it's ONLY 20% efficient.

      I'll admit that spending 5K$ for 6kWp is not that sexy, adventurous or "bleeding edge" as your solar cooker though, ahah
