Agreed with @WattEd on the reality check. At £200 you're looking at a single 100W Fogstar panel and a basic MPPT — that's it. Skip the "all-in-one" rubbish kits.

The WiFi stability issue @HeatherWalker raises is genuinely the elephant in the room. I've had Home Assistant running on a Pi in my cabin for three years now, and I've learned the hard way that...
