About the Aiko Neostar 3S
The Aiko Neostar 3S is our go-to panel for most residential installations across Yorkshire. Aiko Solar holds multiple world efficiency records and the Neostar 3S is built on their proprietary ABC (All Back Contact) cell technology — a design where all electrical contacts are moved to the rear of the cell, eliminating shading from front-side busbars and maximising light absorption. The result is an extraordinary 23.6% peak efficiency across a 440–460W power range, making it one of the most powerful and efficient residential panels available in the UK. Aiko backs the Neostar 3S with a full 30-year product and performance warranty — double the industry standard.
Key Features
ABC All Back Contact Technology
All electrical contacts are positioned on the rear of the cell, eliminating front-side busbar shading entirely. More of the panel's surface captures light — resulting in world-record efficiency figures.
23.6% Peak Efficiency
The highest efficiency residential panel in our range. Generates more power per square metre than PERC or standard TOPCon panels — critical for smaller roofs or where output needs to be maximised.
30-Year Product & Performance Warranty
Aiko backs the Neostar 3S with a 30-year warranty on both the panel itself and its performance — double the industry standard and a direct reflection of ABC technology's exceptional durability.
Best-in-Class Temperature Coefficient
−0.24% per °C means the Neostar 3S loses significantly less power on warm summer days than PERC panels (−0.35%), maintaining high output when your system works hardest.
Exceptional Low-Light Performance
ABC cells maintain strong output in diffuse and low-angle light — ideal for maximising generation during Yorkshire's overcast autumn and winter months.
MCS Eligible
Fully certified for MCS installations, Smart Export Guarantee registration, and all UK grid connection requirements.
Why Premier Electrical installs this product
We specify the Aiko Neostar 3S when our customers want the best overall combination of performance, efficiency, and long-term value. ABC technology eliminates front-contact shading losses entirely, delivering higher output from the same roof space than any PERC or standard TOPCon panel. The 30-year warranty — on both the product and performance — reflects Aiko's confidence in the panel's exceptional durability. For Yorkshire homes where maximising generation per square metre matters, the Neostar 3S consistently outperforms alternatives across the system's lifetime.
