The SKT545-580M10-144D4 series is based on innovative N-type TopCon cell technology, which ensures significantly higher efficiency and better operating characteristics in low-light conditions. Thanks to the bifacial double glass design, these panels effectively utilize light reflected from the ground, allowing for additional energy yield from the rear side of the module. This is a key solution for investors looking for maximum efficiency from limited installation space. The use of 144 cells in M10 format and half-cut technology significantly reduces energy losses at connections and minimizes the risk of hot spots. This series stands out from the competition with its low temperature coefficient, which guarantees stable power production even during a hot summer. The product is primarily dedicated to large-scale solar farms and large industrial facilities where longevity and minimal power degradation are crucial. The use of double tempered glass not only increases mechanical strength against wind and snow loads, but also provides almost complete resistance to light-induced degradation (LID). By choosing this series, the user receives a technologically advanced product that optimizes LCOE costs and accelerates the return on investment in green energy.

Common questions

6 answered
What warranty does the Sunket SKT545-580M10-144D4 series come with?
The SKT545-580M10-144D4 series includes a 15-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty guaranteeing at least 80% of rated power after three decades. This is among the longer power warranties available on the market and a key factor in LCOE calculations for commercial-scale solar investments.
Do the N-type TOPCon cells in the SKT580M10-144D4 series handle summer heat better than older PERC modules?
Yes. The N-type TOPCon cells used in this series have a temperature coefficient of Pmax around -0.29%/°C, compared to roughly -0.35%/°C for standard PERC modules. When cell temperatures reach 70°C on hot days, the SKT580 loses approximately 14.5% of its rated power versus about 17.5% for a PERC module. This difference translates directly into higher annual energy yield.
What is the real-world benefit of the bifacial double glass design in the SKT545-580M10-144D4 series?
The rear side of the module captures light reflected from the ground surface (albedo effect). In ground-mounted systems with light-colored gravel or concrete, bifacial gain typically adds 5-15% extra energy yield. The double glass construction also replaces the UV- and moisture-sensitive backsheet, providing near-total resistance to light-induced degradation (LID) and significantly extending module service life.
Is the SKT545-580M10-144D4 series suitable for residential rooftop installations?
This series is optimized for utility-scale ground-mounted solar farms and large industrial facilities. At approximately 32 kg per module, handling and installation on sloped roofs is challenging. More importantly, the bifacial double glass construction only delivers meaningful additional yield when the rear side is well-illuminated, which is severely limited on pitched rooftops. Lighter, single-glass modules are a better fit for residential prosumer systems.
What do 144 half-cut cells and 16BB busbars mean in the SKT580M10-144D4, and why does it matter?
144 monocrystalline M10 (182 mm) cells are sliced in half using half-cut technology, which reduces the current flowing through each cell and lowers resistive losses. Sixteen busbars (16BB) shorten the electron path and improve electrical contact, boosting cell efficiency to approximately 22.45%. The result is a module that is more resilient to partial shading and significantly less prone to hot spot formation.
Is the Sunket New Energy SKT545-580M10-144D4 series currently available for purchase?
Yes, the SKT545-580M10-144D4 series is active and part of Sunket New Energy's current product lineup. Sunket is a PV module manufacturer based in Wuxi, China, with global distribution. Before ordering, confirm availability of the specific power class you need (e.g., SKT580M10-144D4) with an authorized distributor, as stock levels may vary by region.
