More Power from Every Tile of Roof
We fit AIKO Neostar 3S 490W all-black panels as standard — among the most efficient residential panels available. Advanced back-contact cells generate more even in low light and partial shade, and the all-black finish looks discreet on any roof.
Engineered to Out-generate Ordinary Panels
23%+ cell efficiency means more electricity from the same roof area.
Back-contact cells keep generating when part of the panel is shaded.
A clean, discreet look that sits neatly on any roof.
30-year performance and manufacturer warranties support your investment.
All-Back Contact, Explained
Ordinary panels run their electrical contacts across the front, shading part of each cell. AIKO's ABC design moves them to the back, so more of the cell is exposed to daylight. The result is higher efficiency, better low-light performance and a cleaner all-black look.

Frequently Asked Questions
Why does Spark fit AIKO panels?
AIKO Neostar 3S panels use All-Back Contact (ABC) cell technology, giving them among the highest efficiencies available for home roofs and excellent low-light and partial-shade performance — so you get more energy from the same roof space.
How efficient are AIKO Neostar 3S panels?
They achieve cell efficiencies above 23%, which is at the leading edge for residential panels, with a 490W output per panel.
Do AIKO panels perform well in shade?
Yes. Their back-contact cell design keeps more of the panel generating when part of it is shaded, which helps on typical UK roofs with chimneys or nearby obstructions.
What warranty do AIKO panels come with?
A 30-year performance warranty and a 30-year manufacturer warranty, on top of Spark's 30-year workmanship guarantee. The first 10 years of Spark's workmanship cover are insurance-backed through HIES; years 11–30 are backed directly by Spark.
