AIKO 665W Stellar 3N+ N-Type ABC 72 Cell Silver Frame Dual Glass Solar Panel - 01C Connector
AIKO 665W Stellar 3N+ N-Type ABC 72 Cell Silver Frame Dual Glass Solar Panel - 01C Connector
The AIKO Stellar 3N+ 665 W is an N-Type ABC (All Back Contact) solar panel. AIKO's All-Back-Contact cell design moves every busbar to the rear of the cell, leaving the entire front face free to collect light. It delivers 24.6 % module efficiency from a 2,382 × 1,134 mm frame.
About the AIKO Stellar 3N+ range
The Stellar range is AIKO's utility and commercial line: large-format, silver-framed dual-glass modules aimed at getting the most kilowatt-peak onto a given roof area and cutting the balance-of-system cost per watt that comes with it.
At 2,382 mm tall and 2.70 m² this is a commercial-format module, intended for warehouse and barn roofs, ground mounts and solar farms where the extra length is not a constraint. It is usually too long for a typical domestic roof plane.
Why installers specify this panel
- −0.26 %/°C power temperature coefficient — the array keeps more of its rated output on hot days, when a UK roof can sit far above the 25 °C the nameplate figure is measured at.
- Cell-level shade optimisation — the ABC cell structure recovers output around chimneys, vents and pole shadows without adding a separate optimiser to every module.
- Glass-glass construction — dual glass, 2.0 + 2.0 mm coated semi-tempered front and back instead of a polymer backsheet, for better resistance to moisture ingress and micro-cracking.
- Long-dated warranty — 15-year product warranty and 30-year linear performance warranty; first-year degradation ≤1 %, ≤0.35 % per year from year 2 to 30.
- 0 to +3 % power tolerance — every module is sorted to meet or beat its 665 W nameplate rating.

Array sizing
Each panel covers 2.70 m². A 4 kWp array needs 6 of them (3.99 kWp over about 16 m²). A 6 kWp array needs 9 of them (5.99 kWp over about 24 m²). At 32.2 kg each they are a two-person lift.
About AIKO
AIKO Solar builds every module in its range on ABC (All Back Contact) cells, a structure it developed to move the cell's contacts out of the light path entirely. The design has taken an Intersolar Award and a Red Dot design award, and it is what puts AIKO modules at the top of the mainstream efficiency tables.

Almost any modern string inverter will run it - what matters is the string design. Check the panel's Voc and Isc in the Technical Specifications against your inverter's MPPT voltage window and maximum input current, or send us your inverter model and we'll size it for you.
Divide your inverter's maximum input voltage by the panel's open-circuit voltage (Voc), then leave headroom - Voc rises as temperature falls, so size for the coldest morning rather than the average day.
Panels ship with their factory leads fitted; the connector type and cable length are both listed in the Technical Specifications. Extension leads and additional connectors are ordered separately.
Bypass diodes limit the loss to the affected section rather than the whole panel. Where shading is persistent, panel-level optimisers or micro-inverters recover considerably more yield - ask us and we'll spec it.
The product and performance warranties are listed under the Warranty tab in Technical Specifications, and the manufacturer's full terms are in the Documents section.
