Thanks to their dual-sided construction, these panels can also utilize reflected light from the ground, making it easier to increase production without adding additional modules - particularly in situations where every square meter of roof or ground space is valuable. In practice, they are characterized by **low degradation over time** and stable performance over the long term, which translates into predictable investment profitability. Another advantage is **better performance at high temperatures**, which is particularly important in summer on roofs exposed to direct sunlight. The series solves typical problems associated with installations exposed to uneven lighting conditions, offering **high quality tolerance** and good parameter repeatability. This makes it a sensible choice for homes, businesses, and commercial installations - especially when the goal is high production and long-term reliability. ## Notable figures - At 22.3% efficiency, this panel is on par with typical \*\*TOPCon 400-450W\*\* modules - Power density of 222.7 W/m² matches the \*\*TOPCon 400-450W\*\* median - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 400-450W\*\* panels - 20.2 kg weight - 1.8 kg lighter than \*\*TOPCon 400-450W\*\* median (22.0 kg), reducing installation effort - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface ## Questions ### What is TOPCon technology and why does the SP-N16B/96HG series use it? TOPCon (Tunnel Oxide Passivated Contact) is an N-type silicon cell technology that minimizes recombination losses through a thin tunnel oxide layer. In real-world terms, this delivers module efficiency of 22–23% for the SP-N16B/96HG and lower long-term degradation compared to standard PERC cells. For the end customer it means more kilowatt-hours from the same roof area and more predictable returns over the system's lifetime. ### What real-world energy gain can I expect from the bifacial design of the Solar N Plus SP-N16B/96HG? The SP-N16B/96HG has a bifaciality factor above 85%, meaning the rear side can capture up to 85% of the power the front side generates. Under favorable albedo conditions — light gravel, white roofing membrane, concrete, or snow — real-world bifacial gain typically ranges from 5% to 15% over an equivalent monofacial module. Ground-mounted systems with adequate clearance and flat rooftops with white TPO membranes benefit most. ### What warranty does the Solar N Plus SP-N16B/96HG come with, and what does it cover? The manufacturer provides a 15-year product warranty covering material defects and workmanship, plus a 30-year linear power warranty guaranteeing at least 87.4% of nameplate power at the end of year 30. For a 460 Wp module, that means a minimum output of over 402 Wp after three decades. This compares favorably to older PERC modules that typically guaranteed 80–83% after 25 years. ### How does the SP-N16B/96HG perform in summer heat when roof temperatures spike? The temperature coefficient of Pmax for the SP-N16B/96HG is just -0.29%/°C, one of the lowest figures in the 460 Wp class. Standard PERC modules typically reach -0.35%/°C. At a cell temperature of 75°C, the TOPCon module loses roughly 15% of rated power versus about 19% for a PERC equivalent — a measurable advantage on hot summer days when output matters most. ### Will the Solar N Plus SP-N16B/96HG fit a standard pitched roof and is it manageable to install? At 1762×1134×30 mm and 20.2 kg, the module fits standard residential mounting systems without issue. A two-person installation crew can handle it safely on a pitched roof. The module is compatible with conventional aluminum rail systems and supports a maximum system voltage of 1500 V DC, enabling longer MPPT strings without additional wiring constraints. ### Is Solar N Plus a Tier 1 manufacturer, and should I trust the SP-N16B/96HG for a long-term installation? Solar N Plus is not currently listed on Bloomberg NEF Tier 1 rankings, which is a factor to weigh when assessing manufacturer financial risk. This does not reflect module quality — the SP-N16B/96HG carries positive listings on ENF Solar and is distributed across European markets. Before purchasing, confirm whether the warranty is backed by independent insurance or whether the distributor offers their own guarantee program to protect your investment. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/sp-n16b-96hg440-460w-2024v3-0-80815ad3bbc6.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +50 W, cooler, +2.5 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +45 W, cooler, +2.2 pp | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +45 W, cooler, +2.2 pp | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +40 W, cooler, +2.0 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +40 W, cooler, +2.0 pp | | [Longi Solar LR7-54HJD-495M](https://comparepv.com/panel/longi-lr7-54hjd-495m) | 495 W | +50 W, cooler, +2.0 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +40 W, cooler, +2.0 pp | | [Solar N Plus SP-N16B/96HG-440W](https://comparepv.com/panel/solar-n-plus-sp-n16b-96hg-440w) | 440 W | -0.3 pp | | [Solar N Plus SP-N16B/96HG-450W](https://comparepv.com/panel/solar-n-plus-sp-n16b-96hg-450w) | 450 W | Very close match | | [Solar N Plus SP-N16B/96HG-455W](https://comparepv.com/panel/solar-n-plus-sp-n16b-96hg-455w) | 455 W | +10 W, +0.5 pp | | [Solar N Plus SP-N16B/96HG-460W](https://comparepv.com/panel/solar-n-plus-sp-n16b-96hg-460w) | 460 W | +15 W, +0.7 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +65 W, cooler, +2.7 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +60 W, cooler, +2.4 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +55 W, cooler, +2.2 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +55 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/solar-n-plus-sp-n16b-96hg-445w Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
