The Solar N Plus SP-N16/144HG series has been designed to maximize energy yields under real-world conditions, even when the roof or ground does not provide ideal exposure. These are bifacial modules based on N-type TOPCon technology, which can effectively utilize reflected light from the ground, increasing energy production without requiring any expansion of the installation. The dual-glass construction improves resistance to moisture, temperature changes, and loads, which translates into more stable operation in demanding locations, such as PV farms, carport structures, or industrial halls.

This series also features low degradation and excellent performance in hot weather - a better temperature coefficient means fewer losses on hot days when other modules experience a more significant drop in performance. SP-N16/144HG is the choice for investors who prioritize LCOE, want to minimize maintenance risks, and expect predictable production for many years.

Common questions

6 answered
What warranty does the Solar N Plus SP-N16/144HG come with?
The SP-N16/144HG series carries a 15-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty. This means the manufacturer guarantees that the module will not fall below a defined performance threshold for three decades. It is one of the longer power warranty standards on the market, especially relevant when calculating LCOE for larger-scale installations.
What does bifacial mean for the SP-N16/144HG and does it actually increase energy yield?
Bifacial means the module generates power from both sides — not just the front, but also from light reflected off the ground (albedo). In the SP-N16/144HG, the combination of N-type TOPCon cells and dual-glass construction can deliver an additional 5–20% energy depending on ground surface and tilt angle. The highest gains come from highly reflective surfaces: white gravel, concrete, or snow. On a typical pitched roof the uplift is smaller, but still measurable.
Do the Solar N Plus SP-N16/144HG panels perform well in hot weather and high temperatures?
Yes. N-type TOPCon technology features a better temperature coefficient than older PERC cells. In practice, this means lower power losses on hot days — while standard modules degrade noticeably above 25°C, the SP-N16/144HG maintains more stable output. This matters especially for flat-roof installations on industrial buildings or ground-mount arrays, where modules are exposed to more intense heat buildup.
What installations is the SP-N16/144HG series best suited for — rooftop or ground-mount?
At up to 600 Wp, the SP-N16/144HG is a utility and commercial-class module designed primarily for solar farms, carports, and large-scale rooftop installations on industrial halls and warehouses. The dual-glass construction provides resistance to moisture and mechanical loads, which is critical in demanding locations. For residential rooftop prosumer systems, a smaller module from the same N-type TOPCon technology family would be a better fit.
How does the low degradation of the SP-N16/144HG affect return on investment?
N-type TOPCon cells have one of the lowest annual degradation rates on the market — typically below 0.40–0.45% per year, compared to 0.55–0.70% for standard PERC modules. Over a 30-year operational period, that difference compounds to several percentage points of total energy output, directly lowering LCOE. For investors evaluating a project over multiple decades, the SP-N16/144HG delivers more predictable and higher cumulative yield throughout the module's lifetime.
Is Solar N Plus a Tier 1 manufacturer and how does that affect project financing?
Solar N Plus is not currently listed as a Tier 1 manufacturer by major rating agencies such as BloombergNEF. This does not necessarily indicate lower module quality, but some lenders and insurers may require additional technical due diligence or credit enhancements for bankable projects. Before committing to a larger solar farm, it is advisable to confirm the manufacturer's acceptability with the financing institution or insurance provider.
