The Seraphim Seco solar panel series introduces a new level of quality in the field of energy efficiency, basing its construction on advanced N-type cell technology. This solution effectively eliminates the problem of rapid power degradation in the first years of use, which directly translates into a higher return on investment for homeowners and businesses. A key differentiator of the Seco series is the optimized bifacial design, which allows for the absorption of reflected light from both sides of the module, significantly increasing the total energy yield by more than ten percent compared to standard single-sided solutions. These models are characterized by exceptional resistance to extreme mechanical loads, while maintaining reduced module weight, making them an ideal choice for roofs with limited load-bearing capacity. Thanks to the use of Half-Cut cell technology, these panels perform excellently in partial shading conditions, minimizing power losses. Choosing the Seco series is a guarantee of stable system operation for decades, offering a low temperature coefficient that protects installation performance during hot days. This product is dedicated to investors seeking uncompromising quality, combining modern design with the highest resistance to LID and LeTID degradation phenomena, which puts Seraphim Seco a step ahead of traditional market competition.

Common questions

6 answered
What are the product and power output warranties for the Seraphim Seco series?
Seraphim Seco panels come with a 15-year product warranty covering materials and workmanship, plus a 25-year linear power output warranty. First-year degradation is capped at 2%, followed by approximately 0.55% per year thereafter, ensuring over 80% of rated power after 25 years. These terms are in line with other Tier 1 manufacturers and make the Seco series a solid long-term investment.
What is PERC cell technology used in Seraphim Seco panels, and is it a modern solution?
PERC (Passivated Emitter and Rear Cell) is an advanced monocrystalline silicon cell design that adds a rear passivation layer to reflect photons that would otherwise be lost, pushing module efficiency above 21%. The Seco 555W pairs PERC with multi-busbar wiring and 144 half-cut cells, delivering higher real-world energy yield compared to older full-cell PERC designs.
How do Seraphim Seco 555W panels perform under partial shading from a chimney or antenna?
The 144 half-cut cell layout splits each cell into two independent halves, so shade falling on one half of the module does not suppress output from the other. This significantly reduces mismatch losses compared to full-cell panels. Seraphim Seco is therefore a practical choice for rooftops with chimneys, dormers, or neighboring obstructions that cause intermittent shading.
How much does a Seraphim Seco 555W panel weigh, and is it suitable for a roof with limited load capacity?
The SRP-555 model weighs approximately 32 kg with dimensions of 2278 × 1134 × 30 mm. Before installation on an older or structurally limited roof, a structural assessment is strongly recommended, as the combined load of multiple panels plus racking hardware can be substantial. For roofs with very low load ratings, lighter modules in a lower wattage class may be a safer choice.
Is Seraphim a trustworthy manufacturer, and what does Tier 1 status actually mean in practice?
Seraphim Solar System is a Chinese manufacturer headquartered in Changzhou and classified as Tier 1 by Bloomberg NEF. In practice, Tier 1 means fully automated in-house production lines, a proven track record of project financing from major banks, and consistent product quality. Their 15-year product warranty and established after-sales support make Seraphim Seco a reliable option for residential and commercial installations with a 25-year investment horizon.
Do Seraphim Seco panels lose significant power on hot summer days?
Like all silicon-based PV modules, Seco panels lose some output as cell temperature rises above 25°C STC. The combination of PERC technology, multi-busbar design, and half-cut cells results in a competitive temperature coefficient of approximately -0.34% per degree Celsius. In a central European climate, the thermal impact on annual energy yield is moderate, and the panels maintain stable long-term performance across seasonal temperature swings.
