These modules feature a sleek, full-black aesthetic that complements modern roofs, while also utilizing **n-type TOPCon cell technology** for stable performance over the long term. The use of **glass-glass construction** enhances resistance to environmental factors and reduces the risk of micro-cracks during daily operation, resulting in predictable energy production. The modules also feature a **multi-busbar architecture (MBB)** and dense encapsulation, which improves current transport and reduces losses within the module. In practice, this series helps to address common issues with rooftop solar installations, such as reduced performance in hot weather, reduced performance in cloudy conditions, and the need for a uniform appearance. It is a good choice for homeowners, businesses, and projects where **high reliability** and aesthetics are paramount. ## Notable figures - Efficiency of 22.5% matches the \*\*N-type 450-500W\*\* median - Power density of 225.2 W/m² matches the \*\*N-type 450-500W\*\* median - Temperature coefficient of -0.29%/°C matches the \*\*N-type 450-500W\*\* median - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface - #4108 for efficiency, #2165 for temperature performance out of 14005 panels ## Questions ### What warranty does the Solarspace SSA-48HDB 430-450N series come with? The SSA-48HDB 430-450N series includes a 15-year product warranty and a 30-year linear power output warranty. The long-term power guarantee provides predictable degradation rates over three decades, making ROI projections straightforward. Solarspace is a Tier 1 manufacturer, which adds confidence in the company's ability to honor warranty claims over the long term. ### What is TOPCon technology and what does it offer in the SSA-48HDB 430-450N series? TOPCon (Tunnel Oxide Passivated Contact) is an n-type cell architecture with higher efficiency and lower annual degradation than conventional PERC cells. In the SSA-48HDB series, this translates to better performance under high summer temperatures and reduced losses during overcast conditions, delivering a more stable and higher energy yield throughout the system's lifetime. ### Is the Solarspace SSA-48HDB 430-450N a bifacial module, and when does bifaciality pay off? Yes, the SSA-48HDB is a bifacial module that harvests energy from both the front and rear surfaces. The bifacial gain is most significant in ground-mount systems or installations over light-colored surfaces where reflected irradiance reaches the rear cell. On typical dark roof coverings the bifacial boost is smaller but still measurable. ### Do the SSA-48HDB 430-450N panels look good on a dark roof — what does the full black finish mean? The SSA-48HDB series features a full black aesthetic: black frame, black rear glass, and dark cells create a uniform appearance. It blends seamlessly with dark ceramic tiles, metal roofing, and standing-seam profiles. This design is especially valued in urban residential projects, modern homes, and any installation where visual cohesion is as important as technical output. ### Why does the SSA-48HDB series use a glass-glass construction instead of a glass-backsheet design? The glass-glass (dual-glass) build replaces the conventional polymer backsheet with a second layer of tempered glass. This improves resistance to moisture ingress, UV exposure, and the micro-cracks that gradually reduce power output in standard modules. Combined with n-type TOPCon cells, it makes the SSA-48HDB series the right choice for installations that prioritize longevity and low lifetime operating costs. ### What is the maximum power output of the Solarspace SSA-48HDB and what does it mean for system sizing? The top model in the SSA-48HDB series delivers 450 Wp per module. For a typical residential 10 kWp system, that means roughly 23 panels. Higher per-module wattage reduces total panel count, simplifies BOS wiring, and lowers the installed cost per watt compared to older 380–400 Wp technology. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ssa-48hdb-n-110d50c81e1d.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-48hdb-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.
