Top 10 Solar Mistakes UK

What are the biggest solar panel mistakes?

Top 10 solar panel mistakes UK homeowners make: (1) GETTING ONLY ONE QUOTE — always get 3+. Price varies 20-40%. (2) CHOOSING ON PRICE ALONE — cheapest isn't always best value. Check brands, warranties, reviews. (3) UNDERSIZING THE SYSTEM — install as big as your roof allows. A slightly oversized system costs marginally more but generates significantly more over 25 years. (4) IGNORING SHADING — one shaded panel can reduce the whole system. Insist on a shading analysis. (5) NO BATTERY PLAN — even if you don't install a battery now, get a hybrid inverter (battery-ready). (6) WRONG TARIFF — standard variable tariff wastes money. Switch to Octopus Flux/Go for solar homes. (7) NOT NOTIFYING INSURER — your home insurance should know about solar panels. (8) SKIPPING THE SITE SURVEY — online-only quotes miss roof-specific issues. Always insist on a physical site survey. (9) PAYING 100% UPFRONT — never pay more than 25% deposit. Stage payments protect you. (10) NOT CHECKING MCS — non-MCS installation means no SEG, no building regs cert, limited insurance cover.
