These modules utilize **N-type cells in TOPCon technology**, which translates to high efficiency and better long-term performance compared to many standard solutions. A practical advantage is **lower temperature sensitivity**, meaning energy yield decreases less in hot weather, making the investment more economically viable. The modules also feature **resistance to LID and PID degradation** - which is important for users who want to minimize the risk of performance loss after the first few seasons. The anti-reflective coating enhances performance in diffuse light, while the sealed connection box increases reliability over the long term. The SIRIUS SP-N16/108H will be suitable for both residential and commercial installations, especially where **long-term durability and predictable performance are key** without compromising on quality. ## Notable figures - At 21.3% efficiency, this panel is 0.7pp below the \*\*TOPCon 400-450W\*\* median of 22.0% - Power density of 212.5 W/m² is 7.7 W/m² below \*\*TOPCon 400-450W\*\* median (220.2 W/m²) - needs more roof space - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 400-450W\*\* median - Weight of 21.0 kg is typical for \*\*TOPCon 400-450W\*\* panels - In the top 61% for efficiency among all TOPCon panels ## Questions ### What warranty does the Solar N Plus SIRIUS SP-N16/108H series come with? Solar N Plus provides a 15-year product warranty and a 30-year linear power warranty for the SIRIUS SP-N16/108H modules. This means the panels are guaranteed to retain a specified minimum output level after three decades of operation. The extended warranty is backed by the inherent stability of N-type TOPCon cells, which degrade more slowly compared to conventional PERC technology. ### What is TOPCon technology and why choose the SIRIUS panel over a cheaper PERC module? TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology featuring an ultra-thin tunnel oxide layer and a polysilicon contact that significantly reduces carrier recombination. In practical terms, this means higher module efficiency, a better temperature coefficient, and lower LID degradation in the first year of operation. For a rooftop system running 25-30 years, the cumulative gain in annual energy yield can meaningfully improve the LCOE compared to standard PERC modules. ### Do Solar N Plus SIRIUS 415W panels perform well on hot summer days? Yes. The TOPCon cells in the SIRIUS SP-N16/108H have a more favorable temperature coefficient of power than typical PERC modules — comparable models in this lineup achieve approximately -0.29%/°C. This means that when a roof surface heats up to 60-70°C in summer, power losses are noticeably lower than with older cell technologies, resulting in higher energy yield during the warmest months of the year. ### What is the peak power of the Solar N Plus SIRIUS module, and how many panels does a typical home need? The SP-N16/108H delivers a peak output of 415 Wp. For an average single-family home with annual consumption of roughly 3,500-4,500 kWh (excluding a heat pump), a typical installation of 10-14 panels — totaling 4-6 kWp — is usually sufficient. The exact number depends on roof orientation and pitch, local shading, geographic location, and the MPPT range of the selected inverter. ### Is the SIRIUS SP-N16/108H series resistant to PID and LID degradation? Yes. The SIRIUS SP-N16/108H uses N-type TOPCon cells, which are inherently very resistant to LID (Light Induced Degradation) that occurs during the first hours of sunlight exposure. The manufacturer also certifies resistance to PID (Potential Induced Degradation), a concern in larger string installations operating at high system voltages. This makes the series a solid choice for commercial rooftops and ground-mount projects alike. ### Is the Solar N Plus SIRIUS suited for a residential rooftop, or is it primarily a commercial product? The SIRIUS SP-N16/108H works well in both residential prosumer systems and commercial installations. The 108-cell format at 415 Wp fits standard racking systems designed for pitched or flat residential roofs. It is fully compatible with mainstream inverters available on the market. The 30-year power warranty makes it especially attractive wherever long-term, predictable yield matters — whether on a family home or a larger commercial facility. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/sp-n16-108h-72867c1acbaa.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Just Solar JST-EDMH-(445-465)W-TD (465W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-465w-class) | 465 W | +50 W, hotter, +2.5 pp | | [Luxor Solar LX-465M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-465m-182r-96-gg) | 465 W | +50 W, cooler, +2.5 pp | | [AIKO AIKO-A460-MAH54Mb](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a460-mah54mb-1) | 460 W | +45 W, +2.3 pp | | [Luxor Solar LX-465M/182R188-108+ GG](https://comparepv.com/panel/luxor-solar-lx-465m-182r188-108-gg) | 465 W | +50 W, heavier, +2.3 pp | | [Just Solar JST-EDMH-(445-465)W-TD (460W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-460w-class) | 460 W | +45 W, hotter, +2.3 pp | | [Luxor Solar LX-460M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-460m-182r-96-gg) | 460 W | +45 W, cooler, +2.2 pp | | [Philadelphia Solar PS-MNB108(HCBF)-460W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-460w) | 460 W | +45 W, +2.2 pp | | [JA Solar JAT54S40-460/LR](https://comparepv.com/panel/ja-solar-jat54s40-460-lr) | 460 W | +45 W, cooler, +2.2 pp | | [Solar N Plus SP-M10/108HG-395](https://comparepv.com/panel/solar-n-plus-sp-m10-108hg-395) | 395 W | Hotter, heavier, -1.1 pp | | [Solar N Plus SP-M10/108HG-400](https://comparepv.com/panel/solar-n-plus-sp-m10-108hg-400) | 400 W | Hotter, heavier, -0.8 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +95 W, cooler, +3.7 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +80 W, cooler, +3.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +90 W, cooler, +3.4 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +75 W, cooler, +3.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +85 W, cooler, +3.2 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +85 W, cooler, +3.2 pp | --- Source: https://comparepv.com/panel/solar-n-plus-sp-n16-108h-415 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
