The Solar N Plus SP-N16/144H series is designed for high energy production from the same roof area - these are modules based on N-type TOPCon cells, which maintain their efficiency better in real operating conditions. A key advantage is low sensitivity to high temperatures, which ensures more stable operation in summer and in poorly ventilated areas. In practice, this means more predictable yields and easier planning of self-consumption.

This series of modules also stands out due to high resistance to LID and PID degradation, which limits power losses over time and improves profitability throughout the product lifecycle. The use of half-cut and multi-busbar technology results in better performance under partial shading and reduced losses due to microcracks.

SP-N16/144H is a good choice for PV farms, industrial facilities, and large commercial roofs, where low long-term energy costs and comparable reliability to top-tier N-type modules on the market are important.

Common questions

6 answered
What warranty does the Solar N Plus SP-N16/144H come with?
The manufacturer provides a 15-year product warranty covering physical defects and material faults, plus a 30-year power output warranty. Over those 30 years the module is guaranteed to maintain at least the minimum efficiency stated in the datasheet. This coverage is standard for commercial-grade N-type modules and protects the investment throughout the typical service life of a PV system.
How does TOPCon technology in the SP-N16/144H differ from standard PERC cells?
TOPCon N-type cells feature an ultra-thin tunnel oxide passivation layer that significantly reduces charge-carrier recombination. The result is higher efficiency and stronger resistance to both LID (Light Induced Degradation) and PID (Potential Induced Degradation) compared to P-type PERC cells. In practice, this means a slower power decline over the full 30-year system life and a lower overall LCOE for the installation.
Do SP-N16/144H modules perform well during hot summer days?
Yes, this is one of the key advantages of the series. N-type TOPCon cells have a lower temperature coefficient than older PERC modules, meaning smaller power losses at elevated cell temperatures. Installations on heavily sun-exposed industrial rooftops or facilities with limited airflow maintain higher efficiency on hot days, resulting in more predictable annual energy yield and easier self-consumption planning.
Do SP-N16/144H panels handle partial shading well — for example from a chimney or dormers?
Yes. The half-cut cell layout with 144 cells combined with multi-busbar technology reduces the impact of partial shading on the entire string. Lower operating currents minimize resistive losses and hotspot risk. This is a significant advantage for rooftops where a chimney, neighboring building, or dormers may cast shadows across part of the array during the day.
Is the SP-N16/144H a bifacial module — does it generate power from both sides?
No, the SP-N16/144H is a monofacial module — energy is harvested from the front surface only. The manufacturer did not use a transparent backsheet or glass-glass construction, which simplifies installation and lowers overall BoS costs. The design is well suited for pitched and flat roofs with standard racking where albedo reflection from the surface would be minimal anyway.
What type of projects is the Solar N Plus SP-N16/144H series best suited for?
With a maximum output of 600 Wp per module, the SP-N16/144H targets utility-scale PV farms, industrial buildings, and large commercial rooftops. The high per-module wattage reduces the number of panels needed per megawatt of installed capacity, cutting BoS costs including racking, cabling, and labor. It is not a typical residential module intended for small rooftop prosumer systems.
