Why Is Solar Energy Still Relatively Unpopular in the UK?

While researching renewable energy, I noticed that solar power in the UK still seems to face a fair amount of skepticism and slower adoption compared to some other countries. This surprised me because solar technology has improved a lot over the years, and installation costs have dropped significantly.

However, when reading discussions online or talking to people, there still seems to be criticism or doubt about installing solar panels. Some mention the UK’s weather, others question the financial return or practicality. I’m curious to hear from people with experience in the UK, what are the main reasons behind the hesitation toward solar adoption?
