The MY Solar A&X N-type TOPCon (Bifacial Framed N108) series is designed to maximize energy yield in situations where every square meter of roof space matters. The use of N-type TOPCon cells ensures more stable performance over time, lower degradation-related losses, and better efficiency at higher temperatures - particularly important during summer on roofs with dark-colored surfaces. Thanks to the bifacial design, the module can also utilize light reflected from the ground, resulting in additional yield in ground-mounted systems, on bright roofs, and in configurations with appropriate spacing. The N108 (108-cell) format makes it easy to fit into limited spaces while maintaining a favorable power density. The frame increases rigidity and simplifies mounting in popular racking systems, which installers will appreciate. This is a good choice for homes, businesses, and projects where long-term predictability of production and real profit from both sides of the module are key.

What owners get
N-type TOPCon cells

N-type TOPCon technology delivers a lower LID/LeTID degradation rate and better high-temperature performance than legacy PERC cells, translating into more stable energy yield over the panel's lifetime, especially on dark-colored roofs.

Bifacial design - extra yield

The double-sided module design captures light reflected from the ground, adding extra energy gain in ground-mount installations, on light-colored roof surfaces, and in setups with adequate rear clearance.

30-year power warranty

The 30-year linear power warranty exceeds the market-standard 25 years offered by many segment manufacturers, reflecting stronger confidence in TOPCon cell durability and translating into a lower real LCOE over the long term.

High power density in N108 format

The 108-cell layout, with power up to 450 Wp and efficiency up to 22.53%, delivers favorable power density on limited roof space, easing installation in projects with constrained mounting area.

Frame design eases installation

The framed construction increases mechanical rigidity and ensures compatibility with popular mounting systems, cutting installation time and labor costs in typical rooftop projects.

Trade-offs
Manufacturer outside BNEF Tier-1

Per the provided context, the manufacturer is not classified as BNEF Tier-1 bankable; lack of Tier-1 status can make bank project financing and long-term insurance harder to secure compared to brands like Trina, JinkoSolar, or LONGi that appear on the Q2 2026 Tier-1 list.

Efficiency below top peers

The series' maximum efficiency of 22.53% trails comparable modules such as SunKean/Sunket New Energy's SKT430~450M10-108D5 at 23.04% (a gap of about 0.5 pp, roughly 2.3% relative), meaning slightly more roof area is needed for the same installed power at the same 450 Wp maximum.

About the A&X N-type TOPCon (Bifacial Framed N108) series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

What warranty does the MY Solar A&X N-type TOPCon (Bifacial Framed N108) series carry?
The MY Solar A&X N-type TOPCon N108 series comes with a 25-year product warranty covering materials and workmanship, plus a 30-year power output warranty. The extended power warranty is a key advantage of N-type TOPCon technology over legacy PERC modules, which typically offer only 25 years. It guarantees a minimum level of energy production for three full decades of operation.
Do MY Solar A&X N-type TOPCon bifacial panels provide a real gain on a typical pitched roof?
Bifacial gains are most significant where the rear side of the module receives reflected or diffuse irradiance - ground-mounted systems with light-colored ground cover, bright roofing membranes, or installations with adequate clearance beneath the module. On a dark pitched roof with no airspace behind the panel, bifacial yield gain will be minimal. This should be factored in during system design.
Why are N-type TOPCon cells better than PERC, and does it matter for a residential installation?
N-type TOPCon cells offer a lower temperature coefficient and slower annual degradation compared to PERC. In practice, the modules lose less power on hot summer days when the roof surface heats up significantly. Over a 30-year lifespan, the cumulative energy yield difference becomes noticeable. For a residential rooftop system, this translates to measurably more kilowatt-hours and a faster return on investment.
Does the N108 cell format (108 cells) make installation easier on small or irregular roofs?
Yes. The 108-cell layout results in a slightly more compact module footprint while still reaching up to 450 Wp, making it easier to fit around roof obstructions such as chimneys, skylights, or dormers. The smaller format also simplifies on-roof logistics and handling during installation. The aluminum frame is compatible with standard racking systems widely available on the market.
How does the MY Solar A&X N-type TOPCon series perform on hot days - does high temperature hurt efficiency?
N-type TOPCon technology has a lower power temperature coefficient than PERC - typically around -0.30%/°C versus -0.35%/°C. When a module heats up to 70°C in direct summer sun, the power loss is smaller than with PERC. This matters especially on dark roofing materials where module temperatures routinely exceed 60-70°C. The A&X N108 series maintains higher real-world output during hot, peak-irradiance days.
Does MY Solar hold Tier 1 certification, and is the A&X N-type TOPCon series currently available?
The MY Solar A&X N-type TOPCon (Bifacial Framed N108) series is active and not discontinued. However, MY Solar does not currently appear on Bloomberg NEF Tier 1 module manufacturer lists, which is worth considering when arranging project financing or insurance. Before purchasing, verify local distributor availability and confirm that current IEC 61215 and IEC 61730 certifications are valid with your vendor.
