The use of **N-type cells** allows for minimizing typical power losses over time and maintaining high operational efficiency for many seasons. Furthermore, the **bifacial design** can utilize reflected light from the ground, which significantly improves production on roofs with light-colored surfaces and on ground-mounted installations. The **half-cut architecture** also deserves attention, as it reduces resistive losses and improves the module's performance under partial shading - which is particularly important on roofs with chimneys, skylights, or east-west facing installations. The **anti-reflective glass layer** supports stable operation in low-light conditions, while the high IP rating (**IP68**) increases resistance to moisture and harsh operating conditions. This is a good choice for homes, businesses, and PV farms that require predictable production and long-term reliability without compromising on performance. ## Notable figures - At 22.6% efficiency, this panel is on par with typical \*\*N-type 450-500W\*\* modules - At 226.3 W/m² power density, roof space requirements are typical for \*\*N-type 450-500W\*\* panels - Temperature coefficient of -0.29%/°C matches the \*\*N-type 450-500W\*\* median - At 25.0 kg (1.3 kg above \*\*N-type 450-500W\*\* median of 23.7 kg), requires checking roof load capacity - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces ## Questions ### What does N-type cell technology mean in the Solarspace SS8-60HD 470-495N series and why is it better than PERC? N-type cells used in the SS8-60HD 470-495N series are free from LID (Light Induced Degradation), which affects older P-type PERC modules. This results in a lower annual degradation rate and sustained higher efficiency throughout the panel's service life. Over the 30-year power warranty period, this translates into meaningfully higher total energy production compared to conventional PERC technology. ### Is the Solarspace SS8-60HD series suitable for a roof with chimneys or dormers? Yes, the half-cut cell architecture used in this series splits cells into two independent halves, so shading from a chimney or dormer limits losses only to the shaded cells rather than the entire module. This is a key advantage for installations on typical urban rooftops or east-west orientations where uniform irradiance across the full panel surface is difficult to achieve. ### What is the warranty on Solarspace SS8-60HD 470-495N panels? Solarspace provides a 15-year product warranty covering manufacturing defects and a 30-year linear power warranty for the SS8-60HD 470-495N series. Thanks to N-type technology with a lower annual degradation rate than PERC modules, the panel should retain well above 80% of its rated power output of up to 495 Wp after 30 years of operation. ### Does the bifacial design make sense on a pitched roof with dark roof tiles? The bifacial design delivers the greatest gains in ground-mounted or flat-roof installations where the rear side collects light reflected from a light-colored surface or ground. On a steep pitched roof with dark tiles, the bifacial gain is minimal. In such conditions, the decisive factors are the high front-side efficiency and N-type cell technology, both of which the SS8-60HD series delivers regardless of roof type. ### What installations is the Solarspace SS8-60HD 470-495N series recommended for — residential, commercial, or utility-scale? The SS8-60HD 470-495N series is versatile: power output up to 495 Wp and an IP68 ingress protection rating make it suitable for residential rooftop systems, commercial installations on warehouses, and utility-scale PV farms alike. Solarspace is a Tier 1 manufacturer, which simplifies bankability assessments and accelerates due diligence for larger commercial or industrial projects. ### Do Solarspace SS8-60HD panels generate energy on cloudy days and in low-light conditions? Yes, the anti-reflective coating on the front glass improves absorption of diffuse radiation, resulting in better energy yield under overcast skies. N-type technology also lowers the temperature coefficient of the cells, meaning the module loses less efficiency during hot summer days compared to standard P-type PERC panels. Together, these features improve annual energy yield, particularly in climates with significant cloud cover. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ss8-60hd-n-f17414d5ff71.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +20 W, cooler, +2.4 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +2.2 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +15 W, cooler, +2.1 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +1.9 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +1.9 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | Cooler, lighter, +1.9 pp | | [Solarspace SS8-60HD-470N](https://comparepv.com/panel/solarspace-ss8-60hd-470n) | 470 W | -20 W, -0.9 pp | | [Solarspace SS8-60HD-475N](https://comparepv.com/panel/solarspace-ss8-60hd-475n) | 475 W | -15 W, -0.7 pp | | [Solarspace SS8-60HD-480N](https://comparepv.com/panel/solarspace-ss8-60hd-480n) | 480 W | -10 W, -0.5 pp | | [Solarspace SS8-60HD-485N](https://comparepv.com/panel/solarspace-ss8-60hd-485n) | 485 W | -0.2 pp | | [Solarspace SS8-60HD-495N](https://comparepv.com/panel/solarspace-ss8-60hd-495n) | 495 W | +0.2 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +70 W, cooler, +2.2 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +65 W, cooler, +2.0 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +60 W, lighter, +1.8 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +50 W, cooler, +1.8 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +50 W, cooler, +1.8 pp | --- Source: https://comparepv.com/panel/solarspace-ss8-60hd-490n 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.
