This translates into higher energy yield from the same roof area, which is particularly relevant for prosumer installations with limited available surface. - **Temperature coefficient of -0.31%/°C** - A Pmax temperature coefficient of -0.31%/°C outperforms typical P-type PERC cells (-0.35%/°C), resulting in meaningfully lower power losses on hot days. At a module temperature of 65°C - representative of a Polish summer - the advantage over PERC amounts to approximately 1.4 percentage points of output power. - **30-year product and power warranty** - The manufacturer provides a 30-year warranty covering both the product and power output (≥87.4% after 30 years). Sunova Tangra M Pro HD and Q-SUN Qrystal N10 offer a comparable 30-year warranty structure, while Hiwatt HW-M12/100H remains at the standard 25-year term - placing HT-SAAE on par with the best in class. - **No LID and PID resistance** - N-type TOPCon cells are virtually immune to light-induced degradation (LID/LeTID), as confirmed by both the manufacturer's datasheet and independent analyses. This eliminates the initial years of power loss characteristic of older P-type PERC modules, directly improving energy yield over the full system lifetime. - **BNEF Tier 1, aerospace heritage since 1998** - HT-SAAE is a state-owned enterprise operating under China Aerospace and Science and Technology Corporation (CASC), with a track record in space photovoltaics dating back to the 1960s. Its repeatedly confirmed Bloomberg NEF Tier 1 status ensures bankability and straightforward access to project financing from financial institutions without additional due diligence. ## Cons - **No bifacial variant available** - The HT60-18X(N) series is exclusively single-glass monofacial - the absence of a bifacial option limits its potential in ground-mounted systems or installations over light-colored roofing membranes, where bifacial modules can contribute 5-15% additional annual energy yield. Several competing TOPCon series in a comparable power range (490-505 Wp) already offer a bifacial variant at equivalent pricing. ## About this series The HT-SAAE PANDA Single Glass TOPCon PV Module (HT60-18X(N)) series features **monocrystalline N-type TOPCon cells**, designed for high energy production even under less-than-ideal conditions. Thanks to the TOPCon technology, these modules perform better in low-light and cloudy conditions, resulting in more stable annual energy yields in Polish climates. The single-glass construction ensures **high reliability and operational durability**, while the optimized cell architecture minimizes typical power losses seen in older panel generations. Another key advantage is **low sensitivity to LID degradation** and **enhanced PID resistance**, which helps maintain the predictable performance of the system over a long period. The HT60-18X(N) series is a good choice for residential and commercial installations, especially where maximizing energy output from a limited roof area and reducing the overall system energy cost are priorities. ## Notable figures - Efficiency of 22.9% matches the \*\*TOPCon 450-500W\*\* median - 228.7 W/m² power density - 3.5 W/m² more than \*\*TOPCon 450-500W\*\* median (225.2 W/m²), more power per roof area - At -0.31%/°C, loses 0.02pp more power per degree than \*\*TOPCon 450-500W\*\* median (-0.29%/°C) - At 23.0 kg, weight matches the \*\*TOPCon 450-500W\*\* median - #2412 for efficiency, #8069 for temperature performance out of 14129 panels ## Questions ### What warranty does the HT-SAAE PANDA HT60-18X(N) module carry? The HT60-18X(N) series comes with a 30-year product warranty and a 30-year power output warranty. After 30 years of operation, HT-SAAE guarantees at least 87.4% of the rated power output. The product warranty covers material and workmanship defects, while the power warranty protects against excessive cell degradation - a notably longer coverage than most PERC-based modules on the market. ### Does the TOPCon technology in HT-SAAE HT60-18X(N) actually improve performance on cloudy days? Yes. N-type TOPCon cells show a better spectral response under diffuse light conditions compared to conventional P-type PERC cells. In climates with frequent overcast days, this translates into measurably higher annual energy yield from the same roof area. The low temperature coefficient also limits power losses during hot summer periods, further improving overall LCOE. ### How does the HT-SAAE PANDA HT60-18X(N) differ from older HT-SAAE PERC modules? The key difference is the cell technology: the HT60-18X(N) series uses N-type TOPCon cells instead of P-type PERC. This results in higher module efficiency (up to approx. 22.4%), virtually zero LID and LeTID degradation risk, and better low-light performance. The power warranty has also been extended to 30 years, compared to the typical 25 years offered with older PERC series. ### What is the maximum power output of the HT-SAAE PANDA HT60-18X(N) and which installations is it suited for? The top variant in this series delivers 505 Wp at a module efficiency of approximately 22.4%. At 1909×1134×30 mm and roughly 23 kg, it can be handled and installed by a single technician. The series is well-suited for residential rooftop systems - pitched or flat - as well as small commercial applications where maximizing power density on a limited surface area is a priority. ### Are HT60-18X(N) modules resistant to PID and LID, and what does that mean for long-term reliability? Yes. The N-type cell architecture of the HT60-18X(N) series provides enhanced resistance to PID (Potential Induced Degradation) and virtually eliminates the risk of LID (Light Induced Degradation). In practice, this means the system's power output does not drop sharply after the first seasons of operation, and the manufacturer's 30-year linear power warranty reflects a predictable, stable degradation curve throughout the system's lifetime. ### Do HT-SAAE PANDA HT60-18X(N) modules support 1500 V system voltage, and what does that mean for installers? Yes, the HT60-18X(N) modules are rated for 1500 VDC systems. Higher system voltage allows more panels to be connected per string, which shortens DC cabling runs, reduces resistive losses, and lowers overall BoS (Balance of System) costs. This is especially valuable in commercial and industrial installations where total system cost optimization and MPPT string efficiency are critical design factors. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ht60-18xn-510-panda-au-1-e7f6491f160f.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +15 W, cooler, +2.1 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +1.9 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +10 W, cooler, +1.8 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | Cooler, heavier, +1.8 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +1.6 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, +1.6 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | Cooler, lighter, +1.6 pp | | [HT-SAAE HT60-18X(N)-490W](https://comparepv.com/panel/ht-saae-ht60-18x-n-490w) | 490 W | -0.3 pp | | [HT-SAAE HT60-18X(N)-500W](https://comparepv.com/panel/ht-saae-ht60-18x-n-500w) | 500 W | +0.2 pp | | [HT-SAAE HT60-18X(N)-505W](https://comparepv.com/panel/ht-saae-ht60-18x-n-505w) | 505 W | +10 W, +0.4 pp | | [HT-SAAE HT60-18X(N)-510](https://comparepv.com/panel/ht-saae-ht60-18x-n-510) | 510 W | +15 W, +0.7 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +65 W, cooler, +1.9 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +60 W, cooler, +1.7 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +55 W, lighter, +1.5 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +45 W, cooler, +1.5 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +45 W, cooler, +1.5 pp | --- Source: https://comparepv.com/panel/ht-saae-ht60-18x-n-495w 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.
