The use of **N-type cells in TOPCon technology** ensures stable production over the long term and better performance at elevated temperatures, which is particularly beneficial in summer on rooftops and in ground-mounted installations. The **bifacial** design further allows for the utilization of reflected light from the ground - a significant advantage on bright roofs, gravel, or membranes. The thoughtfully designed half-cut structure enhances **shade resistance** and minimizes losses when part of the module's surface is in less favorable conditions. This is complemented by **double glass**, which increases durability in humid environments, with large temperature fluctuations, and in areas exposed to stress. This is a good choice for installers and investors seeking predictable performance in rooftop and commercial projects, where not only power but also durability and stability are important factors. ## Notable figures - At 23.2% efficiency, this panel is 0.6pp above typical \*\*N-type 500-550W\*\* modules (median: 22.5%) - At 231.6 W/m² power density, this panel generates 6.3 W/m² more per unit area than \*\*N-type 500-550W\*\* median (225.3 W/m²) - Temperature coefficient of -0.29%/°C matches the \*\*N-type 500-550W\*\* median - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface - In the top 11% for efficiency among all N-type panels ## Questions ### What warranty does the Solarspace SSA-54HD 490-515N series carry? Solarspace provides a 15-year product warranty and a 30-year power output warranty for the SSA-54HD 490-515N series. According to the datasheet, the manufacturer guarantees at least 99% of rated power after year one and no less than 87.4% after 30 years of operation. These terms are competitive with other Tier 1 manufacturers serving the European market. ### What does TOPCon cell technology mean for the SSA-54HD series in practice — is it worth the premium? N-type TOPCon cells in the SSA-54HD series deliver a temperature coefficient of Pmax of -0.29%/°C, resulting in lower power losses on hot summer days compared to standard PERC modules. N-type silicon also exhibits lower LID (Light Induced Degradation), so the module loses less power during the initial months of operation. For rooftop and ground-mount projects targeting long-term energy yield, this is a measurable advantage, not just a marketing claim. ### Does the bifacial design of the Solarspace SSA-54HD make sense on a standard tile roof? The bifacial gain is greatest over highly reflective surfaces — gravel, white TPO membranes, or light-colored concrete. On dark roof tiles the rear-side contribution is typically below 5%, making bifacial gain negligible. That said, the dual-glass construction itself adds mechanical durability and moisture resistance regardless of the bifacial application, which is a standalone benefit for any installation environment. ### How much does the SSA-54HD 515N panel weigh, and can a standard roof structure handle it? The Solarspace SSA-54HD 515N weighs 26.5 kg with dimensions of 1961 x 1134 x 30 mm. A structural assessment of the roof is always recommended before installation, especially on older buildings. The installer must also account for combined snow and wind loads. On new or reinforced roofs this weight is within normal parameters for residential and commercial PV arrays. ### Are the SSA-54HD 490-515N panels suitable for a ground-mount solar farm? Yes, the SSA-54HD 490-515N series is well-suited for ground-mount utility and commercial installations. The bifacial dual-glass design enables rear-side energy gain from light reflected off bright ground surfaces, and the 108 half-cut cell layout reduces mismatch losses under partial shading. With up to 515 Wp and module efficiency reaching 23.16%, the series delivers favorable power density for projects where maximizing output per square meter is a priority. ### How does the SSA-54HD 490-515N series perform in summer when panel temperature rises well above 25°C? The temperature coefficient of Pmax for this series is -0.29%/°C, meaning a panel heated to 65°C — a realistic scenario on a Central European rooftop in summer — loses approximately 11.6% of its rated power. This is a notably better result than typical PERC modules rated at -0.35%/°C. In real-world terms, it translates to higher output on hot days and a better annual energy yield over the system's lifetime. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ssa-54hd-n-1b24159c7430.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +1.8 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +1.6 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +45 W, cooler, +1.6 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +1.5 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +40 W, cooler, +1.4 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +1.3 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +1.3 pp | | [Solarspace SSA-54HD-485N](https://comparepv.com/panel/solarspace-ssa-54hd-485n) | 485 W | -30 W, -1.4 pp | | [Solarspace SSA-54HD-490N](https://comparepv.com/panel/solarspace-ssa-54hd-490n) | 490 W | -25 W, -1.1 pp | | [Solarspace SSA-54HD-495N](https://comparepv.com/panel/solarspace-ssa-54hd-495n) | 495 W | -20 W, -0.9 pp | | [Solarspace SSA-54HD-500N](https://comparepv.com/panel/solarspace-ssa-54hd-500n) | 500 W | -15 W, -0.7 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 | -0.2 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +35 W, lighter, +1.2 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | Cooler, lighter, +1.2 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | Cooler, lighter, +1.2 pp | --- Source: https://comparepv.com/panel/solarspace-ssa-54hd-515n 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.
