When is the best time to install solar?

The best time to install solar panels in 2026 is NOW. Every month you delay costs £50-£90 in missed savings. If choosing a specific season: Spring (March-May) is ideal — you capture the full summer generation peak. But autumn/winter installations are cheaper and faster (shorter wait times, possible discounts). 0% VAT is confirmed until March 2027 — install before then to guarantee the lowest price. There is NO benefit to waiting for cheaper panels (prices have stabilised).
