The SunLink SL5N108D series is designed to maximize energy yield in installations where every square meter counts. The use of N-type cells in TOPCon technology minimizes typical degradation-related losses and helps maintain stable performance for years, even under demanding temperature conditions. The modules utilize a Half-Cell design, which improves performance under partial shading and facilitates high production in real roof conditions.

A key feature of the series is its bifacial architecture, which allows for the recovery of additional energy from the rear side - particularly when installed on light surfaces, flat roofs, and ground-mounted structures. The use of a multi-busbar connection design (SMBB) increases resistance to microcracks and improves reliability over the long term.

SL5N108D is a good choice for homes, businesses, and prosumer installations that require high efficiency, better shading tolerance, and predictable yields without compromising on quality.

Common questions

6 answered
What warranty does the SunLink SL5N108D panel carry?
The SL5N108D comes with a 15-year product warranty and a 30-year linear power output warranty. The power warranty guarantees a minimum performance level over three decades — one of the longer output guarantees available on the market. This reflects the manufacturer's confidence in the long-term stability of the TOPCon cell technology used in this series.
Do the SL5N108D panels perform well under partial shading?
Yes, the half-cut cell design in the SL5N108D series significantly reduces power losses caused by partial shading. Splitting each cell in half lowers internal resistance and limits the shadow impact on the full module. The SMBB multi-busbar technology further distributes current across more conductive pathways, improving resilience against typical rooftop obstacles such as chimneys, dormers, or antennas.
What benefit does the bifacial design of the SunLink SL5N108D provide?
Bifacial modules capture solar energy from both the front and rear sides. When installed over a reflective surface — such as a white membrane on a flat roof, gravel, or light-colored ground — the rear side collects reflected irradiance and boosts overall energy yield. The bifacial gain is most pronounced in ground-mount systems and flat-roof installations with adequate substrate albedo.
How do the TOPCon cells in the SL5N108D differ from standard PERC cells?
TOPCon is an N-type cell technology that exhibits lower light-induced degradation (LID) and better long-term power stability compared to P-type PERC cells. In practical terms, the SL5N108D loses less power during the first years of operation and handles high operating temperatures more efficiently, resulting in a higher actual energy yield across the full 30-year service life.
Are the SunLink SL5N108D panels suitable for ground-mount installations?
Yes, the SL5N108D series is an especially strong choice for ground-mount systems. The bifacial architecture allows the rear side to harvest reflected light from the ground surface — sand, gravel, or grass can increase energy yield by several percentage points over a monofacial module. Confirm that the module's mechanical certifications match the structural requirements of your mounting system before installation.
What is the output of the SL5N108D panel and how many modules does a typical home need?
The SL5N108D has a peak output of 455 Wp. A typical single-family home consuming 4,000–5,000 kWh per year generally requires 10–14 modules, yielding a system size of roughly 4.5 to 6.4 kWp. The exact number depends on roof orientation, available roof area, and local solar irradiance — consult a certified installer to size the system accurately.
