The use of **N-type cells in TOPCon technology** results in more stable energy production over the long term, with limited degradation and good performance even in less sunny conditions. This is a practical solution to a common problem faced by installers and investors: how to maximize energy yield from a limited roof area. The Lumina II modules also stand out due to their **favorable temperature coefficient**, which helps maintain efficiency during the summer months when traditional systems lose the most performance. Additional safety is provided by their **robust construction and sealed connection box**, as well as compatibility with popular connectors, which makes installation and maintenance easier. This is a good choice for residential and commercial installations, where **maximizing energy yield from a limited space** and predictable performance over the years are important, and these are supported by a **long linear warranty**. ## Notable figures - At 22.3% efficiency, this panel is on par with typical \*\*N-type 450-500W\*\* modules - At 222.6 W/m² power density, roof space requirements are typical for \*\*N-type 450-500W\*\* panels - At -0.29%/°C, hot weather performance is typical for \*\*N-type 450-500W\*\* panels - At 26.5 kg (2.8 kg above \*\*N-type 450-500W\*\* median of 23.7 kg), requires checking roof load capacity - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof ## Questions ### Are the Solarspace SSA-54HD Lumina II panels bifacial modules, and what does that mean for my system? Yes, the Lumina II series features bifacial modules. The rear side of the panel generates additional energy from light reflected off the roof surface or ground — an effect particularly pronounced with high-albedo surfaces such as white TPO membranes or light-colored gravel. Depending on the installation environment, this can translate to several extra percentage points of annual yield without increasing the system footprint. ### What warranty does the Solarspace SSA-54HD 485-510N (Lumina II) series come with? The manufacturer provides a 12-year product warranty and a 30-year linear power warranty. A linear warranty means degradation is spread evenly across the entire operating period, ensuring the panel retains a defined percentage of its original output after 30 years. This is one of the longer standards available on the market, reflecting the durability inherent to N-type TOPCon cells. ### Why is the N-type TOPCon technology in Lumina II better than older PERC cells? N-type TOPCon cells exhibit significantly lower initial degradation (LID/LeTID) and perform better at elevated temperatures and low irradiance levels. Standard P-type PERC modules typically lose 1 to 3 percent of rated power in the first months of operation due to light-induced degradation, while N-type cells are largely immune to this effect. The result is higher energy yield across the full system lifetime. ### What is the peak power of Solarspace Lumina II panels, and how many modules does a typical residential system need? The top model in the series delivers 510 Wp of peak power. A typical 10 kWp residential system requires approximately 20 modules. The high per-unit power output means you cover less roof area for the same energy production — a significant advantage whenever usable roof space is limited. ### Will the Solarspace SSA-54HD Lumina II series perform well in Central European climate conditions — on overcast days and in winter? Yes. Lumina II modules are engineered for real-world operating conditions, including diffuse irradiance and overcast skies. N-type TOPCon technology delivers better low-light performance than conventional PERC cells. A favorable temperature coefficient also limits power losses during summer months when panel temperatures rise, resulting in more consistent output throughout the year. ### Is Solarspace a reliable manufacturer — are they listed as Tier 1? Solarspace is recognized as a Tier 1 manufacturer by independent PV market analysts. This classification means the company meets strict criteria for financial stability, production capacity, and product quality. Tier 1 status also carries practical weight: modules from such manufacturers are more readily accepted by banks and leasing institutions financing renewable energy projects, making system financing more straightforward. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ssa-54hd-n-1-1895220a00b6.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +2.7 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +2.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +2.4 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +2.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +2.2 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | Cooler, lighter, +2.2 pp | | [Solarspace SSA-54HD-485N](https://comparepv.com/panel/solarspace-ssa-54hd-485n) | 485 W | -10 W, -0.5 pp | | [Solarspace SSA-54HD-490N](https://comparepv.com/panel/solarspace-ssa-54hd-490n) | 490 W | -0.2 pp | | [Solarspace SSA-54HD-500N](https://comparepv.com/panel/solarspace-ssa-54hd-500n) | 500 W | +0.2 pp | | [Solarspace SSA-54HD-505N](https://comparepv.com/panel/solarspace-ssa-54hd-505n) | 505 W | +10 W, +0.4 pp | | [Solarspace SSA-54HD-510N](https://comparepv.com/panel/solarspace-ssa-54hd-510n) | 510 W | +15 W, +0.7 pp | | [Solarspace SSA-54HD-515N](https://comparepv.com/panel/solarspace-ssa-54hd-515n) | 515 W | +20 W, +0.9 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +65 W, cooler, +2.5 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +60 W, cooler, +2.3 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +55 W, lighter, +2.1 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +45 W, lighter, +2.1 pp | --- Source: https://comparepv.com/panel/solarspace-ssa-54hd-495n 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.
