The Solar N Plus SP-N16/108H series consists of monocrystalline modules with a 108-cell array, designed for high efficiency and stable operation under real-world conditions. They are distinguished by TOPCon technology, which helps to minimize energy losses and maintain good performance even when the installation operates at higher temperatures or with reduced sunlight. This is a solution for investors who want to maximize the output from the same roof or ground area.

In practice, SP-N16/108H solves common installation problems such as reduced yield in hot weather, uncertainty about parameters, and the risk of faster degradation. This is made possible by positive power tolerance, which makes it easier to plan the project without unexpected issues after installation, and long linear warranty, which is essential for long-term profitability.

The series is suitable for both single-family homes and small businesses, as well as commercial projects, where high power density and compatibility with modern inverters are important. In addition, the IP68 sealed junction box provides reliability in Polish weather conditions.

Common questions

6 answered
What warranty comes with the Solar N Plus SP-N16/108H panels?
The SP-N16/108H series includes a 15-year product warranty and a 30-year linear power warranty. A linear warranty means degradation is spread evenly over the entire operating period without sharp early drops. This is a key factor when assessing the long-term return on investment for residential rooftop or commercial installations.
What is TOPCon technology in the SP-N16/108H panels and is it worth the premium?
TOPCon (Tunnel Oxide Passivated Contact) is a monocrystalline cell technology that uses a thin tunnel oxide layer to reduce carrier recombination. In practice, SP-N16/108H modules produce more energy under high temperatures and low irradiance conditions compared to legacy PERC modules of the same rated wattage. For a typical installation, this translates to better yield in spring, autumn, and overcast summer days.
How do Solar N Plus SP-N16/108H panels perform in hot weather and partial shading?
TOPCon technology delivers a lower temperature coefficient than standard PERC modules, meaning smaller power losses when cell temperature exceeds 25°C. The 108-cell layout also reduces the impact of partial shading on the entire string. The SP-N16/108H series maintains stable output under real-world operating conditions, which matters in climates with prolonged hot summer periods.
Do the SP-N16/108H panels have a positive power tolerance and what does it mean for my system?
Yes, the SP-N16/108H series features a positive power tolerance. This means a module rated at 440 Wp will never underperform its nameplate value — it may actually exceed it. When sizing a system, this makes it easier to select the right inverter and accurately estimate annual energy yield without the risk of discovering lower-than-expected output after installation.
Are Solar N Plus SP-N16/108H panels compatible with modern hybrid inverters?
Yes, SP-N16/108H modules are compatible with modern hybrid inverters featuring MPPT inputs designed for high-voltage strings. Their high power density and stable electrical parameters simplify inverter selection from leading manufacturers. Before purchasing, always verify that the inverter's maximum input voltage exceeds the string's open-circuit voltage (Voc) at minimum winter temperatures.
Is the Solar N Plus SP-N16/108H series still available for purchase?
The SP-N16/108H series has been discontinued and is no longer actively distributed by the manufacturer. Limited stock may still exist at some distributors, but availability is restricted and a full supply for larger projects cannot be guaranteed. If you are planning a new installation, consider current Solar N Plus series or alternative TOPCon-based modules offering comparable or improved specifications.
