While most peer comparables (Suntech, SunKean) offer warranties at a similar level, the prevailing mass-market standard remains 25 years, making this a genuine competitive advantage for long-term investors. - **Module Efficiency Up to 23%** - The series achieves module efficiency of 22-23%, placing it among the top performers in the full-black monofacial TOPCon 54-cell segment: the Suntech Ultra V Pro mini Full Black tops out at 22.5%, while the SunKean SKT430~450M10-108D5 reaches 23.04% - a lead of just 0.04 percentage points over this series. - **Tier-1 Manufacturer with Industrial Backing** - HT-SAAE (Shanghai Aerospace Automobile Electromechanical Co., Ltd.), founded in 1998, is listed as a bankable Tier-1 manufacturer by BNEF. Its ties to China's aerospace program translate into rigorous quality control and financial stability - both critical factors when evaluating 30-year warranty commitments. - **Low LID/LeTID Risk and Anti-PID Resistance** - N-type TOPCon cells are inherently resistant to light-induced degradation (LID) and light and elevated temperature-induced degradation (LeTID), resulting in a more linear degradation profile throughout the module's operational lifetime. The modules carry certified Anti-PID ratings, which is particularly relevant for systems operating at high system voltages. ## Cons - **Limited Service Network in Poland** - Despite its Tier-1 status, HT-SAAE maintains a significantly smaller network of authorized service partners and distributors in Poland compared to market leaders such as JA Solar or Jinko Solar. In the event of a warranty claim, this may extend response times and complicate module replacement logistics. ## About this series The HT-SAAE HT54-18X(N) PANDA series are modules designed for maximum yield from limited rooftop space - they are based on **N-type cells** and TOPCon technology, enabling better efficiency retention over time and more stable performance at higher temperatures. The application of **half-cut construction** minimizes internal losses and improves resistance to micro-cracking, resulting in more predictable energy production over the long term. In practice, this solution addresses issues common with older technologies for investors seeking to avoid problems such as faster degradation after the initial seasons or power drops under less favorable sunlight conditions. The modules also feature **Full Black aesthetics**, highly valued in residential installations and modern buildings, where a consistent roof appearance matters. The HT54-18X(N) PANDA is ideal for apartment installations and small to medium-sized commercial systems - environments where **high power density**, reliability, and a long operational lifespan without surprises are key. ## Notable figures - Efficiency of 22.3% matches the \*\*TOPCon 400-450W\*\* median - At 222.8 W/m² power density, roof space requirements are typical for \*\*TOPCon 400-450W\*\* panels - -0.31%/°C temperature coefficient - 0.02pp worse than \*\*TOPCon 400-450W\*\* median (-0.29%/°C), expect higher hot weather losses - Weight of 21.0 kg is typical for \*\*TOPCon 400-450W\*\* panels - #5161 for efficiency, #8069 for temperature performance out of 14129 panels ## Questions ### What warranty does the HT-SAAE HT54-18X(N) PANDA series come with? The HT54-18X(N) PANDA series carries a 30-year product warranty and a 30-year power output warranty. After 30 years of operation, the manufacturer guarantees at least 87.4% of the rated power, corresponding to an annual degradation rate of approximately 0.4%. This is among the best figures currently available for residential and small commercial PV modules. ### How does TOPCon technology in the HT54-18X(N) PANDA series differ from standard PERC modules? The N-type TOPCon cells in the HT54-18X(N) PANDA series deliver a notably lower temperature coefficient (approx. -0.31%/°C vs. -0.35%/°C for typical PERC) and significantly better resistance to light-induced degradation (LID). In real-world terms, this means smaller power losses on hot days and a slower overall output decline over the system's lifetime compared to older PERC technology. ### Are the HT-SAAE HT54-18X(N) PANDA panels suitable for small roofs or roofs with obstructions such as chimneys or dormers? Yes. The modules measure approximately 1722×1134 mm and weigh around 21 kg, which fits standard pitched-roof mounting systems. The half-cut cell design (108 cells split into two independent strings) is particularly valuable here: when a chimney or dormer partially shades the panel, only the shaded half is affected, limiting overall power loss compared to conventional full-cell modules. ### What is the rated power and efficiency of the HT54-18X(N) PANDA panels? The HT54-18X(N) PANDA series is available in power classes ranging from 430 W to 450 W, with module efficiency up to 22.5%. This high power density means fewer panels are needed to cover a given roof area compared to older-generation modules, which is a critical advantage when mounting space is limited. ### Does the Full Black finish of the HT54-18X(N) PANDA panels reduce their energy output? The black frame and black backsheet of the Full Black version absorb marginally more heat than standard silver components, which can slightly raise the module's operating temperature. In practice the difference in energy yield is negligible, while the uniform, all-black aesthetic is highly valued in residential installations and modern buildings where roof appearance matters. ### Is HT-SAAE a reliable manufacturer, and is the HT54-18X(N) PANDA series still available? HT-SAAE (Shanghai Aerospace Automobile Electromechanical Co.) holds Tier 1 status on the Bloomberg NEF bankability list, confirming its financial stability and ability to honor long-term warranties. The HT54-18X(N) PANDA series is currently active and available for purchase - it has not been discontinued. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ht54-18xn-440-panda-au-2-60a908156bfb.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +50 W, cooler, +2.0 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +50 W, cooler, +2.0 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +50 W, cooler, +2.0 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +50 W, cooler, +2.0 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +50 W, cooler, +2.0 pp | | [HT-SAAE HT54-18X(PD)-F 400W](https://comparepv.com/panel/ht-saae-ht54-18x-pd-f-400w) | 400 W | -35 W, heavier, -1.8 pp | | [HT-SAAE HT54-18X(PD)-F 405W](https://comparepv.com/panel/ht-saae-ht54-18x-pd-f-405w) | 405 W | -30 W, heavier, -1.6 pp | | [HT-SAAE HT54-18X(PD)-F 410W](https://comparepv.com/panel/ht-saae-ht54-18x-pd-f-410w) | 410 W | -25 W, heavier, -1.3 pp | | [HT-SAAE HT54-18X(PD)-F 415W](https://comparepv.com/panel/ht-saae-ht54-18x-pd-f-415w) | 415 W | Hotter, heavier, -1.0 pp | | [HT-SAAE HT54-18X(PD)-F 420W](https://comparepv.com/panel/ht-saae-ht54-18x-pd-f-420w) | 420 W | Hotter, heavier, -0.8 pp | | [HT-SAAE HT54-18X(ND)-F 425W](https://comparepv.com/panel/ht-saae-ht54-18x-nd-f-425w) | 425 W | -10 W, heavier, -0.5 pp | | [HT-SAAE HT54-18X(ND)-F 430W](https://comparepv.com/panel/ht-saae-ht54-18x-nd-f-430w) | 430 W | Heavier, -0.3 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +75 W, cooler, +2.7 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +60 W, cooler, +2.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +70 W, cooler, +2.4 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +70 W, cooler, +2.4 pp | --- Source: https://comparepv.com/panel/ht-saae-ht54-18x-n-435w Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
