The HT60-18X(N) PANDA series of photovoltaic modules introduces a new quality to rooftop installations through the use of advanced N-type TOPCon cell technology. This solution effectively eliminates the key problem of light-induced degradation (LID) and potential-induced degradation (PID), which guarantees investors stable performance and a significantly longer system lifespan compared to traditional P-type solutions. Thanks to their unique cell architecture, these panels are characterized by excellent performance in low light, which in Polish climate conditions translates into real gains even on cloudy days. These models also feature high bifacial efficiency, allowing for the generation of additional energy from the rear of the module, making them unrivaled on bright surfaces or ballast-type mounting systems. A key advantage of the PANDA series is its low temperature coefficient, limiting power losses during summer heat, which directly impacts a higher annual electricity yield. This product is dedicated to demanding residential users and companies focusing on maximizing self-consumption and component durability. Unlike standard competitor products, HT-SAAE combines innovative doping with exceptional mechanical resistance to snow and wind loads in this series, ensuring full investment security for years and making it the optimal choice for professional photovoltaics.

What owners get
Highest Efficiency Among Peers

The maximum module efficiency of 23.6% places the PANDA series above its direct competitors: JA Solar JAM60S40 LR (23.0%), Sunlike Solar SKT510 (22.93%), and Trina Solar Vertex Backsheet (21.2%). The +0.6 percentage point advantage over JA Solar translates into meaningfully higher energy yield from the same roof area.

N-type TOPCon Technology - No LID/PID

N-type TOPCon cells exhibit negligible light-induced degradation (LID) and potential-induced degradation (PID) compared to P-type PERC cells - a critical advantage in Polish climate conditions where high humidity and variable system voltages promote PID. The temperature coefficient of Pmax is -0.31%/°C, which is competitive against JA Solar's TOPCon offering at -0.30%/°C.

30-Year Product and Power Warranty

The manufacturer guarantees ≥87.4% of nominal power output after 30 years, backed by a 30-year product warranty covering materials and workmanship. By comparison, JA Solar's JAM60S40 series carries only a 12-year product warranty with an equivalent 30-year power guarantee - a meaningful distinction for long-term investors.

Tier-1 Manufacturer, State-Owned Enterprise Since 1998

HT-SAAE (Shanghai Aerospace Automobile Electromechanical Co., Ltd.) is a Chinese state-owned enterprise with over 25 years of PV manufacturing history, classified as Tier-1 by BNEF. State ownership substantially reduces the risk of manufacturer insolvency over the warranty period, a key criterion for project bankability.

Wide Power Range: 490-510 Wp Across 5 Variants

Five available power variants spanning 490-510 Wp simplify system design by enabling precise matching to inverter specifications - such as staying within MPPT input limits - and maximizing roof plane utilization without the need to cut modules.

Trade-offs
Low Brand Recognition in the Polish Market

HT-SAAE holds a significantly smaller share of the Polish residential and prosumer installation market than JA Solar or Trina Solar. This limited brand presence may complicate bank financing for larger projects - some lenders maintain approved-manufacturer lists - and could negatively affect the residual value of the installation in the event of a property sale.

About the HT60-18X(N) PANDA series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

What is TOPCon technology in the HT-SAAE PANDA panels and is it worth choosing?
TOPCon (Tunnel Oxide Passivated Contact) is a next-generation N-type cell technology. In the HT60-18X(N) PANDA series, it enables module efficiency up to 23.6%, well above standard PERC panels. Key advantages include near-complete elimination of LID and an exceptionally low temperature coefficient of -0.31%/°C, delivering higher annual energy yield compared to conventional P-type modules - especially relevant in climates with variable irradiance.
What warranty does the HT60-18X(N) PANDA series come with?
The HT60-18X(N) PANDA series includes a 30-year product warranty and a 30-year linear power output warranty. The manufacturer guarantees at least 89.4% of rated power after 25 years and 87.4% after 30 years of operation. First-year degradation is under 1%. This is among the most comprehensive warranty coverage available in the residential and commercial PV module market.
Do HT60-18X(N) PANDA panels perform well under low-irradiance and overcast conditions?
Yes. N-type TOPCon cells demonstrate superior low-light spectral response compared to PERC technology, generating measurable additional kilowatt-hours on overcast days. With module dimensions of 1909 × 1134 mm and up to 510 Wp peak power, the series delivers strong annual energy production even on limited roof space - a key advantage in high-latitude markets with frequent diffuse irradiance conditions.
How do PANDA 510W panels perform during summer heat - do they lose significant power output?
The temperature coefficient of Pmax at -0.31%/°C is among the best values for crystalline silicon modules. For every degree Celsius above 25°C, the panel loses only 0.31% of its rated power. At a typical summer cell temperature of 60°C, power losses are noticeably lower than with older PERC technology, directly improving energy yield during the hottest months and increasing overall annual LCOE efficiency.
Are HT60-18X(N) PANDA panels resistant to LID and PID degradation that affects older modules?
Yes. N-type TOPCon cells are structurally immune to Light-Induced Degradation (LID) and highly resistant to Potential-Induced Degradation (PID) - both common failure modes in P-type PERC cells. HT-SAAE guarantees 87.4% of rated power after 30 years of operation, with first-year degradation below 1%. This ensures predictable long-term performance and a reliable return on investment throughout the system lifetime.
Is HT-SAAE a reliable solar panel manufacturer worth trusting for a long-term investment?
HT-SAAE (Shanghai Aerospace Automobile Electromechanical Co.) is a Bloomberg Tier 1 manufacturer - the highest reliability rating in the PV industry based on financial stability and production capacity. The company's ties to China's aerospace sector reflect strict quality control standards. The PANDA series is actively distributed globally, with warranty support available through authorized distributors across Europe and beyond.
