Most irritating to me is that Few components are manufactured to be interchangeable / replaceable / repairable with other brands.
I am reminded of the solar hot water craze 30 years ago.......I would guess less than 5% of those systems are still operational. As manufacturers go bankrupt their parts can become almost impossible to get.
I see no efforts to standardize the interchangeability of components ....
I’d imagine similar issues with lack of standardization have occurred with early adoption of any new technology. I wonder how long it took, to standardize lightbulbs to sockets?
