The AIKO Neostar 3 and the LONGi S10 are two of the most advanced home solar panels sold in the UK, and at 495W there is very little between them. AIKO is slightly more efficient per square metre (24.8% against 24.3%), while LONGi loses less output in heat and offers an identical 30-year performance guarantee. On most UK roofs, either panel gives you the same system size, so the better choice depends on your roof’s heat, shading and layout rather than the brand.
