Our read of the datasheet
The Neostar 2P54 is AIKO's 108-cell back-contact rooftop panel, offered from 450 W to 485 W. The 465 W bin reviewed here is 23.3% efficient and the 485 W top bin 24.3%. At 1757 x 1134 mm it is 5 mm shorter than the common 1762 mm size, so it fits most standard layouts.
The -0.26%/°C temperature coefficient is among the lowest in this guide, and the power warranty guarantees 88.85% after 30 years, based on 1% loss in year one and 0.35% a year after. AIKO also lists partial-shading optimisation among the design features. Power binning is 0 to +3%.
It is a single-glass panel with 3.2 mm tempered glass and a black frame, and at 20.6 kg it is the lightest panel here. The product warranty is 25 years, and the datasheet lists a 40 mm hail test at 27.5 m/s.
We have not tested this panel. This summary follows from the manufacturer's published specifications, checked 23 September 2026.
