The idea that solar is only worth it if you have a lot of north-facing roof dates from a time when the panels were expensive. The panels are now ridiculously cheap. You can face them north, south, west or east and still make plenty of electricty. For example, panels on a south-facing roof in Australia still produce more electricity than panels on the best-facing roofs in the UK. Always buy as many panels as you can afford, with EVs coming you won’t ever regret having more. And get micro—inverters (i.e. one per panel), they maximise how much you produce even when some might be shaded.
