The Solar N Plus SP-N16/108H lightweight module has been designed for installations where both power output and ease of transport and assembly are important. These modules are based on N-type monocrystalline cells with TOPCon technology, which maintain their parameters over time and are less susceptible to typical degradation phenomena seen in older designs. In practice, this means more stable energy production over many years, as well as a better return on investment.

A key feature of this series is its lightweight design, which makes it easier to work on roofs with limited load-bearing capacity, in retrofit projects, and where minimizing on-site loads and logistics is important. The use of an anti-reflective coating helps to more effectively utilize light in varying solar conditions, and the high IP rating of the junction box increases resistance to moisture and dust.

This is a good choice for homes, small businesses, and premium projects where technology, durability, and practical installation are all important considerations.

Common questions

6 answered
What is TOPCon cell technology in the Solar N Plus SP-N16/108H series and why does it matter?
TOPCon (Tunnel Oxide Passivated Contact) is an N-type technology that reduces recombination losses at cell contacts through a thin passivation layer. In real-world terms, the SP-N16/108H delivers higher output per unit of irradiance and a low temperature coefficient of approximately -0.29%/°C. Compared to older PERC modules, TOPCon degrades more slowly over time, which means more stable long-term energy production and a better return on investment.
How lightweight is the SP-N16/108H series and can it be installed on a roof with limited load capacity?
The SP-N16/108H is marketed as a Lightweight Module. At dimensions of 1722×1134×30 mm, it weighs approximately 24 kg — competitive for a 108-cell, 440 W class module. This makes it a practical choice for retrofit projects on older buildings or roofs with limited structural load capacity. The reduced weight also simplifies transport across the roof surface and installation without heavy lifting equipment.
What warranty does the Solar N Plus SP-N16/108H come with?
Solar N Plus offers a 15-year product warranty covering material and workmanship defects, and a 30-year power output warranty with a guaranteed minimum of 87.4% of rated power at end of life. Before purchasing, verify that the local distributor provides in-country warranty support, as Solar N Plus is not currently listed among BNEF Tier 1 manufacturers.
Do Solar N Plus SP-N16/108H panels perform well in winter and on cloudy days?
Yes. The N-type TOPCon technology provides a low temperature coefficient of approximately -0.29%/°C, meaning the module actually gains power output when cell temperature drops below 25°C (STC) during cold winter conditions. The anti-reflective coating also helps capture diffuse and low-angle irradiance typical of northern European winters and overcast days, making it a reliable year-round performer.
Is the SP-N16/108H series a bifacial panel?
No, the standard SP-N16/108H series is a monofacial panel — energy is harvested from the front surface only. If you need additional energy gain from ground-reflected irradiance (albedo effect), typically relevant for ground-mounted systems with a light-colored substrate, you should consider a bifacial module variant instead.
Who is the Solar N Plus SP-N16/108H best suited for — is it a good choice for a residential installation?
The SP-N16/108H series targets residential homes, small businesses, and premium installations where a combination of high efficiency, durability, and installation convenience matters. With up to 440 W peak power, a lightweight frame, and a 30-year power warranty, it is a solid N-type TOPCon option for buyers who want advanced cell technology without the premium price of Tier 1 brands.
