Seraphim YUKON Series panels redefine efficiency standards by using advanced half-cut cell technology, which drastically reduces internal energy losses and minimizes the risk of hot spots. This design is based on an innovative multi-busbar layout, which not only shortens the current flow path but also increases the module's resistance to micro-cracks and mechanical degradation. This solution is a response to the challenges of operating in difficult lighting conditions, ensuring stable energy production even with partial shading of the surface. The use of multi-busbar technology translates into higher conversion efficiency, making this series an optimal choice for investors seeking a fast return on investment. YUKON models perform excellently in both large-scale photovoltaic farms and demanding commercial installations, where maximizing the use of available roof or ground space is key. Compared to standard solutions, this series offers a better temperature coefficient, which guarantees high operating efficiency on hot days. It is a reliable foundation for modern energy systems, combining engineering precision with exceptional component durability.

Common questions

6 answered
What warranty does the Seraphim YUKON Series come with?
The Seraphim YUKON Series carries a 30-year product warranty and a 30-year power output warranty. This is among the longest coverage periods available in the PV module market. The power warranty guarantees that the panels will maintain a specified efficiency level for three decades of operation, significantly reducing investment risk and supporting accurate ROI calculations.
How does the Seraphim YUKON Series perform in high temperatures?
The YUKON Series features a better temperature coefficient than standard PERC modules, which means less power loss on hot, sunny days when conventional panels underperform. This is particularly important for south-facing rooftop systems or ground-mounted installations with limited natural cooling, where thermal losses have a measurable impact on annual energy yield.
Is the YUKON Series a bifacial panel?
No, the YUKON Series is a monofacial module — it captures sunlight from the front surface only. This eliminates the need for a highly reflective ground surface and simplifies system design and installation. The series is well suited for standard rooftop and ground-mount applications where bifacial gain would be negligible.
What is the half-cut cell technology in the YUKON Series and does it make a real difference?
Half-cut technology splits each PERC cell into two halves, reducing the current flowing through each one. The result is lower resistive heat, reduced susceptibility to microcracks, and better performance under partial shading — for example when a chimney or antenna covers part of the panel. Combined with a multi-busbar layout, this translates into measurably higher annual energy production compared to standard full-cell modules.
Are the Seraphim YUKON 610 Wp panels suitable for large-scale solar farms and commercial projects?
Yes, the YUKON Series with up to 610 Wp per module is designed for utility-scale farms and demanding commercial installations. The high unit power reduces the number of modules needed for a given system capacity, cutting costs on racking, cabling, and labor. As a Bloomberg Tier 1 manufacturer, Seraphim also meets the bankability requirements typical of large project financing.
Is Seraphim a reliable manufacturer and is the YUKON Series still available?
Seraphim is a Chinese manufacturer on the Bloomberg Tier 1 list, operating since 2011 with annual production capacity exceeding 13 GWp. The YUKON Series is active and currently available. Tier 1 status means the modules qualify for bank and infrastructure fund financing — a standard requirement in commercial and utility-scale project tenders.
