The Solarspace SS8-60HD 470-495N series is designed to maximize energy yield in situations where every square meter counts. 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.

Common questions

6 answered
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.
