The Solar N Plus SP-N16/108HG series is designed for maximum energy yield in situations where every square meter of roof space counts. These modules utilize N-type cells in TOPCon technology, which help minimize losses under real-world operating conditions, especially at higher temperatures and under variable sunlight. In practice, this translates to more predictable energy production and a better return on investment over the course of a year.

The use of a double-glass construction enhances resistance to microcracks and material fatigue, which is important for installations exposed to wind, snow, and frequent thermal cycling. Another key feature is bifaciality - the module can also utilize reflected light from the ground, increasing energy yield in ground-mounted installations, on bright roofs, and on carport structures.

This is a good choice for prosumers and companies that want reduced degradation over time and stable module performance over the long term, without compromising on quality.

Common questions

6 answered
What warranty does the Solar N Plus SP-N16/108HG series come with?
The SP-N16/108HG series includes a 15-year product warranty covering material and workmanship defects, and a 30-year power output warranty guaranteeing at least 87.4% of rated power after three decades of operation. This is one of the longer power warranty standards available on the market, providing reliable investment planning over a 30-year horizon.
Do the bifacial SP-N16/108HG modules actually produce more energy than standard panels?
Yes. The bifacial design of the SP-N16/108HG captures irradiance from both the front and rear surfaces, harvesting light reflected from the ground, a light-colored roof, or surrounding surfaces. In practice this delivers an additional 5–25% energy yield depending on installation conditions. The gain is greatest in ground-mount systems, on light-colored surfaces, and in carport structures where the rear side of the module receives significant reflected irradiance.
How does the SP-N16/108HG perform on hot summer days at high temperatures?
The TOPCon N-type cell technology features a low temperature coefficient of approximately –0.29%/°C, outperforming conventional PERC modules. A 10°C rise in panel temperature causes only about 2.9% power loss — noticeably less than older technologies. In real-world conditions, where rooftop panel temperatures frequently exceed 60–70°C in summer, this translates into measurably higher actual energy yield.
How does the glass-glass construction of the SP-N16/108HG differ from standard backsheet modules?
Conventional panels use a polymer backsheet that can absorb moisture and develop microcracks over time. The SP-N16/108HG uses tempered glass on both sides, significantly improving mechanical strength, eliminating backsheet degradation risk, and extending module service life. The dual-glass structure handles thermal cycling, snow loads, and high-wind conditions more reliably — especially important for exposed rooftop and ground-mount installations.
Is the SP-N16/108HG series suitable for installation on a standard pitched roof?
Yes. The SP-N16/108HG modules measure 1722×1134×30 mm and weigh approximately 24 kg, compatible with standard rail-and-clamp racking systems used in residential rooftop installations. However, due to the dual-glass construction, these panels are heavier than backsheet modules. For larger systems, it is advisable to verify roof load capacity with your installer and select an appropriately rated mounting structure.
What does the lower degradation rate of the SP-N16/108HG mean for a system owner?
TOPCon N-type cells degrade more slowly than conventional PERC technology, with an annual power loss of approximately 0.35–0.40%. After 25 years the panel retains close to 90% of its initial output, and the manufacturer's warranty guarantees a minimum of 87.4% after 30 years. For the system owner this means more predictable energy production and greater savings over the long term without the need to replace modules prematurely.
