Strong in heat, no clear weak spot
The AIKO Neostar 1S series was designed for maximum energy yield on limited rooftop space - without compromising on aesthetics. Key here is the N-Type ABC (all back contact) cell technology, or rear-contact architecture, ensuring the module's front remains uniform and better utilizes light. This translates to high efficiency even under less-than-ideal conditions - elevated operating temperatures, transient overcast periods, and partial edge shading.
Neostar 1S is also a Full Black with no visible front grid lines, genuinely facilitating the integration of the installation into modern architecture and meeting investors' requirements. An additional advantage is low long-term degradation, ensuring stable energy production for years and making the investment return more predictable. In residential and small commercial applications, you also benefit from BOS cost optimization - more power from fewer modules, simpler wiring and installation. Neostar 1S stands out where every square meter, appearance, and long-term reliability matter.

Top 9% of the Back Contact 400-450 W segment, against a median of -0.290. Ranked 511th in the whole database.

The ABC (All Back Contact) N-type technology provides a Pmax temperature coefficient of -0.26%/°C, as confirmed by AIKO's datasheet. This represents a significant advantage over standard TOPCon (~-0.30%/°C) and PERC (~-0.35%/°C) technologies, resulting in a demonstrably higher yield, especially during hot summer days.
The TÜV NORD report confirms that ABC AIKO modules generate up to 30% more energy than a standard TOPCon module under full shading of a single cell. In installations with chimneys, antennas, or edge shading, Neostar 1S maintains a significantly better energy production compared to technologies with front-mounted contacts.
The absence of metallic rails on the front (Back Contact) creates a uniformly black surface for the panel. Compared to competitors in the same price range (e.g., Lina Energy LEPV 132 Ultra Premium, which has a visible grid), the Neostar 1S is the preferred choice for architectural requirements and BIPV projects.
The manufacturer guarantees ≥88.85% of the nominal power after 30 years, with an annual degradation of ≤0.35% (≤1% after 1 year). The comparable KDM Kingdom Solar KDM Series does not offer an equivalent 30-year linear warranty, making AIKO's offer more competitive in the long term.
AIKO Solar is listed on the BNEF Tier 1 Module Manufacturers list (methodology updated on March 18, 2026), which guarantees access to project financing and minimizes the manufacturer's residual risk throughout the warranty period.
Neostar 1S offers a 15-year product warranty, while newer AIKO series (Neostar 2S+, 3S+) already have a 25-year warranty. For example, the Luxor ECO LINE N-TYPE TOPCon Non-Reflect panel from the peer segment also offers a 25-year product warranty. This represents a significant difference for investors calculating ROI over 15 years.
The maximum efficiency of the Neostar 1S is 22.5%, while the Luxor ECO LINE N-TYPE TOPCon Non-Reflect achieves 22.86% at the same peak power of 440 Wp. On roofs with limited surface area, the difference of approximately 0.36% translates into a significantly smaller number of modules that can be installed for the same square meter budget.
- At 22.5% efficiency, this panel is on par with typical Back Contact 400-450W modules
- Power density of 225.3 W/m² matches the Back Contact 400-450W median
- -0.26%/°C temperature coefficient (median: -0.29%/°C) - retains ~1% more power at high temperatures
- #4222 for efficiency, #511 for temperature performance out of 14005 panels
