Yes Dave! This is the question everyone should be asking. The answer is, unfortunately, still most likely Chinese. Try searching Alibaba, there is tons of equipment there. Also, if solar indexed stimulus ever starts (As I argue it needs to), to have any kind of economy in a solar powered world, you might look at hydrogen generation in your solar installation, even if you have all EVs, Its a fuel that is going to come into big demand by aerospace, after fossil fuels bite the dust, every domestic and community installation with more or less unlimited funds for building up more solar hydrogen capability, so as to make yet more funds, will be strongly motivated to max out on hydrogen generation.
