The SunKean SKT415~435M10-108D4 series are modules based on the TOPCon technology, designed for high energy production even under less-than-ideal conditions. The use of a double-glass structure increases resistance to environmental factors, stabilizes performance over the long term, and makes it easier to select panels for installations where durability is key. Furthermore, these are bifacial modules, meaning they can also utilize reflected light from the ground - allowing you to generate more energy from the same surface, especially on light roofs, membranes, and ground-mounted installations.

In practice, this series solves common problems for investors: limited space, reduced energy production in hot weather, and the risk of faster module degradation. Thanks to the half-cut design and the 16BB multi-busbar structure, the panel better handles micro-shading and internal losses, resulting in more stable string performance. This makes it a good choice for homes, businesses, and PV farms where predictable energy yields and long-term durability are important.

Common questions

6 answered
What warranty comes with the SunKean SKT415~435M10-108D4 solar panels?
SunKean provides a 15-year product warranty and a 30-year linear power output warranty. Over those 30 years, the module must maintain energy production within the degradation curve specified by the manufacturer. This is one of the longer warranty standards available for premium-class PV modules and is a meaningful factor when calculating the total cost of ownership over the system's lifetime.
What does bifacial mean for the SunKean SKT435M10-108D4, and how much extra energy can it produce?
Bifacial means the module generates power from both sides. The front captures direct solar irradiance while the rear collects light reflected from the roof surface or ground (albedo effect). The actual energy gain depends on surface reflectivity and mounting height, but on white membranes or ground-mount systems it can add several to over ten percent compared to a conventional monofacial module at the same rated 435 Wp.
Why choose TOPCon over PERC technology in the SunKean SKT415~435M10-108D4 series?
TOPCon (Tunnel Oxide Passivated Contact) achieves higher cell efficiency than legacy PERC by reducing recombination losses through superior surface passivation. This translates into higher power output from the same footprint, a lower temperature coefficient meaning less power loss on hot days, and slower long-term degradation. The SKT415~435M10-108D4 series reaches its peak output of 435 Wp specifically because of this cell technology.
How do half-cut cells and 16 busbars (16BB) affect the performance of a SunKean SKT435M10-108D4 system?
Half-cut cells split each cell in two, reducing internal resistance and heat dissipation, and limiting the impact of partial shading on the rest of the string. The 16BB design provides more current pathways, further lowering resistive losses. The practical result is more stable string output under partial shading conditions caused by chimneys, antennas, or neighboring structures, improving overall MPPT efficiency.
Are the double glass SunKean SKT415~435M10-108D4 panels heavier, and does the roof structure need reinforcement?
Yes, dual-glass construction is heavier than standard backsheet modules, so the mounting structure — whether roof-based or ground-mount — must be engineered to accommodate the additional weight. In return, you gain significantly higher mechanical strength, moisture resistance, and protection against PID (Potential Induced Degradation), extending the module's service life. These advantages are especially valuable in commercial rooftop and utility-scale installations.
Is the SunKean SKT415~435M10-108D4 series suitable for utility-scale PV farms?
Yes, this series is well suited for ground-mount and utility-scale solar farms. The bifacial design captures reflected ground irradiance, which improves energy yield without increasing land use. The reinforced double glass construction withstands demanding field conditions including moisture, wind loads, and thermal cycling. The 415–435 Wp power range allows efficient string design and reduces the total module count needed to reach target farm capacity.
