Fewer than 6% of modules tested worldwide achieve top scores in all 7 categories simultaneously - making this an objective benchmark of manufacturing quality. - **30-Year Product and Power Output Warranty** - The manufacturer guarantees ≥87.4% of nominal power output after 30 years, with an annual degradation rate of ~0.4% (1% in year one). The industry standard for most mid-range manufacturers remains a 25-year linear power warranty with a degradation floor of ~84.8%, making HT-SAAE's offering a materially better proposition for investors modeling full system lifecycle costs. - **23.0-23.9% Efficiency - Segment-Leading Performance** - The series achieves module efficiency of up to 23.9%, on par with direct competitors (Huasun Everest G12R: 23.9%, JA Solar JAT60S41 LR: 23.9%) and well ahead of weaker rivals (Lu'an Solar MO: 22.32%). Higher efficiency directly reduces the roof area required to achieve a target system power output. - **N-Type TOPCon: Low LID/LeTID and Superior Thermal Performance** - N-type TOPCon cells deliver a temperature coefficient of Pmax of -0.31%/°C (versus -0.35%/°C for typical PERC), translating into measurably higher daily energy yield during summer operating conditions. N-type technology also eliminates light-induced degradation (LID) and light- and elevated temperature-induced degradation (LeTID) that are characteristic of older P-type cells. - **Tier-1 Bankable Manufacturer with Aerospace Heritage Since 1998** - HT-SAAE (Shanghai Aerospace Automobile Electromechanical Co., Ltd.) is classified as a Tier-1 manufacturer by major financial institutions, facilitating project financing. Its aerospace-derived quality management system and fully automated production lines minimize the risk of latent manufacturing defects. ## Cons - **Limited Brand Recognition in Europe** - HT-SAAE does not appear in European market share rankings (Jinko ~13%, JA Solar ~11% globally) and has a limited distribution network compared to segment leaders. For commercial projects where bankability must be demonstrated to institutional lenders, the brand's limited name recognition may require additional due diligence documentation - even with Tier-1 status in hand. ## About this series The HT-SAAE HT60-18X(N) series are monofacial modules based on **N-type cells**, designed to maintain high energy production in real-world operating conditions. The application of **half-cut technology** improves the system's performance under partial shading and minimizes losses at connections, which is particularly important on rooftops with chimneys, window wells, or antennas. This is an excellent choice for investors seeking stable returns even during winter and under poorer insolation conditions-N-type modules typically perform better in low light and degrade slower over time. In practice, the HT60-18X(N) helps reduce the cost of energy from installations thanks to higher surface efficiency and more predictable performance across a wide temperature range. The series stands out for its **high resistance to external conditions** (sealed junction box, robust construction) and the availability of versions with black or silver frames, facilitating adaptation to roof aesthetics. This is a solution for single-family homes and businesses that rely on **long-term warranty and guaranteed energy yield**. ## Notable figures - At 23.3% efficiency, this panel is 0.6pp above typical \*\*TOPCon 500-550W\*\* modules (median: 22.7%) - Power density of 232.7 W/m² packs 5.3 W/m² more into the same footprint vs \*\*TOPCon 500-550W\*\* median (227.4 W/m²) - Temperature coefficient of -0.31%/°C is 0.02pp worse than \*\*TOPCon 500-550W\*\* median (-0.29%/°C) - higher losses in summer heat - Weight of 23.5 kg (3.5 kg below \*\*TOPCon 500-550W\*\* median of 27.0 kg) allows easier transport and roof mounting - Ranked #1017 out of 14005 panels for efficiency in the database ## Questions ### What warranty do the HT-SAAE HT60-18X(N) panels come with? The HT60-18X(N) series comes with a 30-year product warranty and a 30-year power output warranty. For three full decades, the manufacturer guarantees module efficiency above the threshold specified in the warranty terms. This is one of the longest warranties available in the PV market and reflects the manufacturer's confidence in the long-term durability of TOPCon technology and N-type cells. ### Do the HT60-18X(N) panels perform well in winter and on overcast days? Yes. N-type TOPCon cells have a lower temperature coefficient (approx. -0.31%/°C) compared to older PERC cells, resulting in smaller losses at high temperatures and better performance under diffuse winter irradiance. N-type modules show higher sensitivity at low light levels, keeping the system productive even on overcast days typical of Central European fall and winter seasons. ### What is the peak power of the HT-SAAE HT60-18X(N) and who is it designed for? The HT60-18X(N) series reaches a peak power of up to 530 Wp. These modules are suited for both single-family residential rooftops and small commercial installations where high power density on limited roof area matters. At approximately 1909×1134 mm, they fit standard racking systems, and output above 500 Wp allows building an efficient system with fewer panels. ### What does half-cut cell technology offer in the HT60-18X(N) on a roof with chimneys or dormers? Half-cut means each cell is sliced in half, giving the module 120 smaller cells instead of 60 standard ones. Under partial shading from a chimney, antenna, or dormer, only the shaded section loses power while the rest of the module continues operating normally. This reduces energy losses and extends connection longevity thanks to lower internal current flowing through the cells. ### Is HT-SAAE a trustworthy Tier 1 solar panel manufacturer? Yes, HT-SAAE is rated a Tier 1 manufacturer by PV industry rating agencies, confirming verified financial standing and production capacity. The company, headquartered in China, supplies modules to European, Australian, and other global markets. The HT60-18X(N) series holds certifications meeting the requirements for grid-connected installations across the European Union. ### Is the HT60-18X(N) series available with a black frame, and does it affect roof installation? Yes, the HT60-18X(N) series is offered in both a black frame and a silver aluminum frame variant. The black frame version integrates more aesthetically on roofs with dark coverings such as ceramic or bituminous tiles. For residential customers who care about the visual appearance of their home, this is often a key selection factor that has no impact on the module's electrical specifications. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ht60-18xn-520-530-au-2-7ff2cbed8f10.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, +1.7 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +1.5 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +45 W, cooler, +1.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | -10 W, cooler, +1.4 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | Cooler, heavier, +1.4 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +40 W, cooler, +1.3 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | -25 W, cooler, +1.2 pp | | [HT-SAAE HT60-18X(ND)-F-495W](https://comparepv.com/panel/ht-saae-ht60-18x-nd-f-495w) | 495 W | -20 W, heavier, -0.9 pp | | [HT-SAAE HT60-18X(ND)-F-500W](https://comparepv.com/panel/ht-saae-ht60-18x-nd-f-500w) | 500 W | -15 W, heavier, -0.7 pp | | [HT-SAAE HT54-18X(N)-500W](https://comparepv.com/panel/ht-saae-ht54-18x-n-500w) | 500 W | -15 W, -0.8 pp | | [HT-SAAE HT60-18X(ND)-F-505W](https://comparepv.com/panel/ht-saae-ht60-18x-nd-f-505w) | 505 W | -10 W, heavier, -0.5 pp | | [HT-SAAE HT54-18X(N)-505W](https://comparepv.com/panel/ht-saae-ht54-18x-n-505w) | 505 W | -10 W, -0.6 pp | | [HT-SAAE HT60-18X(N)-510W](https://comparepv.com/panel/ht-saae-ht60-18x-n-510w) | 510 W | -0.3 pp | | [HT-SAAE HT54-18X(N)-510W](https://comparepv.com/panel/ht-saae-ht54-18x-n-510w) | 510 W | -0.4 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, lighter, +1.1 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +25 W, cooler, +1.1 pp | --- Source: https://comparepv.com/panel/ht-saae-ht60-18x-n-515w 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.
