The SunLink SL5N108 POWER+ series are Full Black modules based on N-type TOPCon cells, designed for high performance in real rooftop conditions. The use of a half-cut design minimizes losses in partially shaded conditions and supports more stable energy production throughout the day - particularly in areas where obstructions (chimneys, skylights, trees) can reduce sunlight exposure. Furthermore, the SMBB architecture improves current collection and helps reduce the risk of microcracks, which translates to long-term installation reliability.

A key feature of this series is its bifacial capability, which allows you to utilize reflected light from bright surfaces - a real advantage on roofs with light-colored membranes, carports, and ground-mounted installations. The low temperature coefficient characteristic of TOPCon helps maintain performance on hot days, and the robust IP68 connection box supports resistance to harsh working environments. This is a good choice for investors who want to combine premium aesthetics with technology focused on stable performance and durability.

Common questions

6 answered
What warranty comes with the SunLink SL5N108 POWER+ TOPCon panels?
SunLink provides a 15-year product warranty covering material defects and workmanship on the SL5N108 POWER+ modules. The linear power output warranty extends to 30 years, guaranteeing the panel will maintain at least its minimum rated output in line with the degradation curve throughout that period — a longer coverage than the 25-year standard common with older PERC technology.
How does N-type TOPCon technology differ from PERC cells in the SunLink SL5N108?
N-type TOPCon cells have a lower temperature coefficient than PERC, meaning less power loss on hot days. They also degrade more slowly — typically below 0.4% per year versus 0.45–0.55% for PERC. In practice, over 30 years of operation a TOPCon module will generate measurably more energy than a same-wattage PERC panel.
Are SunLink SL5N108 POWER+ 445 Wp panels suitable for a roof with partial shading?
Yes. The half-cut cell design splits each cell in two, significantly limiting the impact of shade from a chimney, dormer, or antenna on the entire module's output — losses are much lower than with conventional full-size cells. The SMBB architecture further improves current collection and reduces the risk of microcracks, supporting long-term reliability under demanding rooftop conditions.
Are the SunLink SL5N108 POWER+ Full Black panels bifacial?
No. The SL5N108 POWER+ 440–445 W Full Black is a monofacial module — it harvests energy from the front side only. The all-black aesthetics (black frame, black cells, black backsheet) are designed for a premium rooftop appearance, not dual-sided light harvesting. If you need a bifacial option, consider the lower-wattage variant in the same SL5N108 lineup (420–435 W).
What does the IP68 junction box rating mean on SunLink SL5N108 POWER+ panels?
An IP68-rated junction box is waterproof even during prolonged submersion — the highest ingress-protection standard used in PV modules. This means temporary roof flooding during heavy rain, wet snow, or condensation will not compromise the panel's electrical connections or shorten the installation's service life.
SunLink is not a Tier 1 manufacturer — is that a risk for a residential solar installation?
The Tier 1 classification is produced by analysts such as Bloomberg NEF primarily for large-scale PV farms and project lenders — its absence does not indicate poor product quality. For residential prosumers, the key factors are certifications (IEC 61215, IEC 61730), warranty terms (15-year product, 30-year power output), and after-sales support availability. SunLink holds the required industry certifications and actively updates its module portfolio.
