In practice, it combines **TOPCon type N cell technology** with **bifacial construction**, allowing for better utilization of reflected and diffused light - particularly on light roofs, membranes, and ground-mounted systems with appropriate ground cover. This solution helps reduce energy losses in less ideal conditions and increases the predictability of the system's performance. Modules from this series offer **stable performance over time** thanks to a long power warranty, which is important for investors who calculate LCOE and return on investment. The use of a **protected IP68 connection box** and industrial-grade components supports resistance to moisture and more demanding operating conditions. Lumina II is suitable for homes, small businesses, and commercial projects where **maximizing energy yield per square meter of roof** and long-term reliability are key. ## Notable figures - At 22.5% efficiency, this panel is on par with typical \*\*N-type 450-500W\*\* modules - At 225.2 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 - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof - In the top 29% for efficiency among all N-type panels ## Questions ### What is N-type TOPCon cell technology and why does the Solarspace Lumina II series use it? TOPCon (Tunnel Oxide Passivated Contact) is an N-type silicon cell technology offering higher efficiency than conventional PERC. In the SSA-48HD 430-455N modules, it delivers up to 22.77% panel efficiency and a low temperature coefficient of Pmax at -0.29%/°C, meaning less power loss on hot days. N-type cells are also highly resistant to LID (light-induced degradation), resulting in more stable energy output throughout the 30-year operating cycle. ### Is the Solarspace SSA-48HD 455W panel suitable for a standard pitched roof? Yes. The module measures 1762×1134×30 mm and weighs 24.5 kg. Because the glass-glass construction is heavier than panels with a traditional backsheet, the roof's load-bearing capacity should be verified beforehand. On pitched roofs with light-colored tiles or a white membrane, the module's bifacial design captures additional reflected light, boosting energy yield. IEC 61215 and IEC 61730 certifications confirm its suitability for standard residential and commercial rooftop installations. ### What warranty comes with the Solarspace SSA-48HD 430-455N Lumina II modules? The manufacturer provides a 15-year product warranty covering physical and material defects, plus a 30-year linear power warranty. First-year degradation is guaranteed at less than 1%, and after 30 years the module retains at least 87.4% of its rated power. These figures are solid when calculating LCOE and estimating return on investment for both residential and commercial solar projects. ### Does the Lumina II SSA-48HD series perform better than PERC panels on cloudy days and in winter? Yes. N-type TOPCon cells have a superior low-light response compared to PERC technology, translating to higher energy yield in autumn, winter, and overcast conditions. The low temperature coefficient (-0.29%/°C) minimizes power loss on hot summer days, while the bifacial design captures additional diffuse light from the rear surface. Both effects together improve the predictability of annual energy production. ### What practical benefits does the bifacial design of the SSA-48HD modules offer in ground-mounted or flat-roof installations? The bifacial SSA-48HD modules harvest energy from both the front and rear surfaces thanks to their glass-glass construction. In ground-mounted systems with a reflective surface such as gravel, concrete, or a light-colored geomembrane, or when combined with tracking systems, this can increase yield by 5–15% compared to an equivalent monofacial module. On flat roofs with white EPDM or PVC membranes, the bifacial gain is also noticeable, especially in summer when the albedo of the substrate is at its highest. ### Are the Solarspace SSA-48HD Lumina II modules resistant to moisture and harsh weather conditions? Yes. The SSA-48HD 430-455N series features an IP68-rated junction box, providing full protection against continuous water immersion. The glass-glass construction additionally shields the cells from moisture ingress, mechanical micro-cracks, and UV degradation more effectively than conventional backsheet panels. This makes the series particularly well-suited for ground-mounted systems, flat roofs, and environments with elevated humidity or frequent precipitation. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ssa-48hd-n-d160581b5039.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +45 W, lighter, +2.3 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +40 W, lighter, +2.0 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +50 W, cooler, +2.0 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +50 W, lighter, +2.0 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | +50 W, lighter, +2.0 pp | | [GCL GCL-NR10R/54BGDF](https://comparepv.com/panel/gcl-gcl-nr10r-54bgdf) | 500 W | +50 W, cooler, +2.0 pp | | [Solarspace SSA-48HDB-430N](https://comparepv.com/panel/solarspace-ssa-48hdb-430n) | 430 W | -20 W, -1.0 pp | | [Solarspace SSA-48HD-435N](https://comparepv.com/panel/solarspace-ssa-48hd-435n) | 435 W | -15 W, -0.8 pp | | [Solarspace SSA-48HD-440N](https://comparepv.com/panel/solarspace-ssa-48hd-440n) | 440 W | -10 W, -0.5 pp | | [Solarspace SSA-48HD-445N](https://comparepv.com/panel/solarspace-ssa-48hd-445n) | 445 W | -0.2 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +60 W, cooler, +2.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +55 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/solarspace-ssa-48hd-450n 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.
