Why aren't perovskite panels available yet?

Durability — perovskite degrades faster than silicon when exposed to moisture, heat, and UV light. Researchers are solving this with encapsulation and stable compositions. Once solved: rapid commercialisation expected.

Will perovskite replace silicon?

More likely: perovskite ON TOP of silicon (tandem cells). This combines silicon's durability with perovskite's high efficiency. A tandem panel could reach 28-30% efficiency — 40% more than current panels.

Should I wait for perovskite before installing?

No — waiting 5-10 years costs £3,000-£11,000 in missed savings. Current panels are excellent and proven. When perovskite arrives, it may be available as an upgrade or replacement option.

Who is developing perovskite in the UK?

Oxford PV (Oxford) is the leading UK perovskite company — they're manufacturing tandem perovskite-silicon cells. Also: Swansea University (printed perovskite) and Imperial College (stability research).

What are perovskite solar panels?

Perovskite solar cells are the most exciting development in solar technology: EFFICIENCY: lab records of 33.9% (tandem perovskite-silicon) vs 26.8% for silicon alone. Commercial target: 28-30% (vs 20-22% for current panels). COST: potentially 50% cheaper to manufacture — perovskite is made from abundant, cheap materials. FORM FACTOR: can be printed on flexible, lightweight substrates — solar on windows, walls, vehicles. CURRENT STATUS: Not yet available for home installation. Durability challenges (degradation in moisture and UV). Expected commercial availability: 2028-2030 for tandem cells on existing silicon panels. SHOULD YOU WAIT? No — current silicon panels are excellent (20-22% efficient, 25-year warranty, proven). Install now and benefit from 25 years of savings. Perovskite will be an upgrade option in 5-10 years.
