What are the disadvantages of solar panels?

The real disadvantages of UK solar panels: (1) Upfront cost £5,000-£8,000. (2) Weather-dependent — less output in winter/cloud. (3) Not all roofs suitable (north-facing, heavy shading). (4) Still need grid electricity (evenings, winter). (5) Inverter replacement at 10-15 years (£800-£1,500). (6) Aesthetic impact (some find panels unappealing). (7) Cannot take with you when moving. (8) Panel degradation (0.4%/year). (9) Battery adds cost for evening use. These are honest cons — but for most UK homes, the pros (£14,500-£27,000 lifetime savings, 100-400% ROI) decisively outweigh them.
