Best month to buy solar panels — data from MCS installation patterns and installer surveys: CHEAPEST: October-November. Installer demand drops 20-30% after summer rush. Some offer 5-10% discounts to maintain workflow. Wait times: 2-4 weeks (vs 6-12 in spring). MOST POPULAR: March-June. Highest demand. Longest wait times (6-12 weeks). Prices at seasonal peak. WORST VALUE: January-February. Prices are normal but you install in the lowest-output months, missing spring generation. Though savings accrue over 25 years so this matters little. THE REAL ANSWER: Every month of delay costs £50-£90 in missed savings. A 5% discount (£350 on a £7,000 system) is offset by just 4-6 months of delay. OPTIMAL STRATEGY: Get quotes in August-September. Install in October-November. Ready for spring/summer generation. Best price + shortest wait + captures full solar season.
