Ranked 13,982nd in the whole database. - **86.7 kg per kWp** - Bottom 20% of the TOPCon 350-400 W segment, against a median of 68.9. - **Best for:** Residential and shaded-installations. - **Not ideal for:** Tight roof space, roofs where every square metre has to count and weight-limited structures. ## Specification ### Electrical - **Rated power (Pmax):** 375 W - **Efficiency:** 14.50 % - **Voltage at Pmax (Vmp):** 28.10 V - **Current at Pmax (Imp):** 13.35 A - **Open-circuit voltage (Voc):** 33.60 V - **Short-circuit current (Isc):** 14.21 A - **Max system voltage:** 1500 V ### Temperature - **Temperature coefficient of Pmax:** -0.310 %/degC - **Temperature coefficient of Voc:** -0.250 %/degC - **Temperature coefficient of Isc:** 0.046 %/degC - **NOCT:** 43 degC ### Cell and construction - **Cell type:** Monocrystalline - **Cell technology:** TOPCon - **Cell count:** 96 - **Bifacial:** yes - **Bifacial gain:** 13.50 ### Physical - **Length:** 2278 mm - **Width:** 1134 mm - **Thickness:** 30 mm - **Weight:** 32.5 kg - **Area:** 2.58 m2 - **Power density:** 145.2 Wp/m2 ### Warranty and degradation - **Product warranty:** 30 years - **Performance warranty:** 30 years - **Output guaranteed at end of warranty:** 87.4 % - **First-year degradation:** 1.00 % - **Annual degradation:** 0.40 % - **Output after 30 years:** 328 W ## Rank in the whole catalogue | Measure | Position | | --- | --- | | Efficiency | 14007 of 14129 | | Power density | 13982 of 14129 | | Temperature coefficient | 8069 of 14129 | | Weight | 13960 of 14129 | | Warranty | 21 of 14129 | ## Pros - **N-type TOPCon - Low Degradation and LID Resistance** - N-type TOPCon cells degrade at approximately 0.4%/year compared to 0.7-0.8% for P-type PERC. Near-zero Light-Induced Degradation (LID) means the module does not lose several percent of its rated power in the first weeks of operation, as is commonly observed with PERC modules. - **30-Year Product and Power Output Warranty** - The manufacturer guarantees ≥87% of rated power after 30 years-an above-standard commitment compared to most P-type modules (Trina, JA Solar), which offer 25 years with a floor of 84.8%. The 30-year product warranty also covers workmanship defects, which is uncommon in this market segment. - **Double Glass Construction** - A rear glass pane in place of a polymer backsheet eliminates the risk of delamination, provides a lower water vapor transmission rate (WVTR), and improves resistance to cell microcracks. This is particularly relevant for rooftop installations subjected to freeze-thaw cycles and high wind loads. - **Bifacial Design with Half-Cut Cells** - The bifacial architecture enables an additional 5-15% energy yield from light reflected off high-albedo surfaces such as roofing membranes and gravel ballast. Half-cut cells reduce resistive losses and improve tolerance to partial shading-mismatch losses are confined to one half of the module rather than propagating across the entire string. - **Tier 1 Bankable Status - Warranty Credibility and Project Financing** - HT-SAAE has maintained Tier 1 status according to BloombergNEF (BNEF) for many years and is a subsidiary controlled by China Aerospace and Science Technology Corporation (CASC). Bankable status enables project financing through institutional lenders and provides a substantive basis for enforcing the 30-year warranty. ## Cons - **Below-Average Module Efficiency for a 2023-Generation TOPCon Product** - Module efficiency of 14.5-15.3% is significantly below what current TOPCon technology can deliver and well behind peer comparables: the Waaree EDO PRO reaches 19.83% and the Meyer Burger Black achieves 21.5%. A 10 kWp system using this series requires approximately 65-67 m² of roof area, whereas modules rated at ~20% efficiency would occupy roughly 50 m²-a meaningful difference where available roof space is constrained. ## About this series The HT-SAAE HT48-18X(ND)-F series are modern **N-type TOPCon** modules designed for stable, long-term operation with minimal degradation. The application of **half-cut technology** enhances performance in real-world conditions by reducing heat-related losses and optimizing output when the installation is partially shaded or operating under scattered light. A key advantage of this series is its **double glass construction**, which increases resistance to moisture, temperature fluctuations, and micro-cracking - particularly important for roofs exposed to harsh weather conditions. Additionally, thanks to **bifacial capability**, the modules can utilize reflected light from the ground surface, helping boost energy yield in well-maintained installations (bright roof, gravel, membranes). This is an excellent choice for premium residential installations and demanding rooftop projects where durability, aesthetics, and predictable inverter performance in varying conditions are essential. ## Notable figures - Efficiency of 14.5% is 1.5pp below the \*\*TOPCon 0-400W\*\* median (16.0%) - Power density of 145.2 W/m² is 14.6 W/m² below \*\*TOPCon 0-400W\*\* median (159.8 W/m²) - needs more roof space - At -0.31%/°C, loses 0.02pp more power per degree than \*\*TOPCon 0-400W\*\* median (-0.29%/°C) - At 32.5 kg, this panel is 9.0 kg heavier than the \*\*TOPCon 0-400W\*\* median (23.5 kg) - more demanding for installation crews - Bifaciality factor of 75% can add 4-11% extra yield with reflective mounting surface ## Questions ### What warranty does the HT-SAAE HT48-18X(ND)-F series come with? The HT48-18X(ND)-F series is backed by a 30-year product warranty and a 30-year power output warranty - one of the longest coverage periods available in the PV module market. HT-SAAE is a Tier 1 manufacturer, which means proven production quality and the financial stability needed to honor warranty claims throughout the full operational lifetime of the system. ### What are the practical benefits of the double glass construction in the HT48-18X(ND)-F modules, and does it make sense for roof installations? Instead of a standard polymer backsheet, HT48-18X(ND)-F modules use two tempered glass layers. This significantly improves resistance to moisture ingress, micro-cracks, and rapid temperature swings - particularly relevant on roofs exposed to harsh weather. The longer mechanical service life reduces total system costs over the 30-year warranty period. Keep in mind that double glass modules are heavier than standard single-glass panels, so roof load capacity and racking ratings should be verified before installation. ### Does the bifacial design of the HT48-18X(ND)-F panels actually increase energy production in real-world conditions? Yes, but the gain depends on the specific installation. The bifacial HT48-18X(ND)-F modules harvest light from both the front glass and the rear glass. Typical bifacial gains range from 5-15% on highly reflective surfaces such as white roofing membranes, gravel, or light-colored substrates. On a standard dark sloped roof, the bifacial effect is minimal. The technology delivers the best results on flat roofs, ground-mount systems, or pergolas with high-albedo surroundings. ### Do the TOPCon cells in the HT48-18X(ND)-F series perform better than PERC on overcast days? Yes. The N-type TOPCon cells used in the HT48-18X(ND)-F feature a lower temperature coefficient and superior low-light response compared to standard PERC technology. In climates with frequent overcast days, this translates into higher annual energy yields. The absence of LID (Light Induced Degradation) also means the module operates at full rated power from day one, with no initial output dip after first exposure to sunlight. ### Is the HT48-18X(ND)-F series a good fit for a standard sloped residential roof? Yes. The HT48-18X(ND)-F modules, rated up to 395 Wp, are designed for prosumer installations including sloped roofs. The half-cut cell technology reduces output losses caused by partial shading from chimneys, dormers, or antennas. However, because double glass construction adds weight compared to single-glass framed panels, it is important to confirm that the roof structure and racking system are rated to handle the additional load before installation. ### How does the half-cut cell technology in the HT48-18X(ND)-F improve performance under partial shading? In half-cut modules, each cell is split in two, lowering internal resistance and reducing hot-spot risk. When part of the module is shaded by a chimney, tree branch, or antenna, the overall power loss is significantly smaller than in a conventional full-cell design. The HT48-18X(ND)-F benefits from this by delivering more stable MPPT tracking to the inverter under variable real-world conditions, minimizing energy losses across the entire system. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ht48-18xnd-f-395-au-1-f1d05fd077bc.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | 18 kg lighter, +8.6 pp, -5 yr warranty | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | 18 kg lighter, +8.6 pp, -5 yr warranty | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | -35 W, 16 kg lighter, +8.5 pp | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | -15 W, 16 kg lighter, +8.5 pp | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | 15 kg lighter, +8.5 pp | | [Gamko New Energy GKA210M400W (1/2\*4\*20)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-2-4-20) | 400 W | +25 W, lighter, +8.5 pp | | [Gamko New Energy GKA210M400W (1/4\*4\*40)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-4-4-40) | 400 W | +25 W, lighter, +8.5 pp | | [Gamko New Energy GKA210M380W (1/2\*4\*19)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19) | 380 W | 15 kg lighter, +8.5 pp | | [Maxeon SPR-MAX3-400-COM](https://comparepv.com/panel/maxeon-spr-max3-400-com) | 400 W | Lighter, +8.1 pp, +10 yr warranty | | [Maxeon SPR-MAX3-425-R](https://comparepv.com/panel/maxeon-spr-max3-425-r) | 425 W | Lighter, +7.9 pp, +10 yr warranty | | [HT-SAAE HT40-18X(ND)-310W](https://comparepv.com/panel/ht-saae-ht40-18x-nd-310w) | 310 W | -65 W, heavier, -2.4 pp | | [HT-SAAE HT40-18X(ND)-F-310W](https://comparepv.com/panel/ht-saae-ht40-18x-nd-f-310w) | 310 W | -65 W, -2.5 pp | | [HT-SAAE HT40-18X(ND)-315W](https://comparepv.com/panel/ht-saae-ht40-18x-nd-315w) | 315 W | -60 W, heavier, -2.2 pp | | [HT-SAAE HT40-18X(ND)-F-315W](https://comparepv.com/panel/ht-saae-ht40-18x-nd-f-315w) | 315 W | -60 W, -2.3 pp | | [HT-SAAE HT40-18X(ND)-320W](https://comparepv.com/panel/ht-saae-ht40-18x-nd-320w) | 320 W | -55 W, heavier, -2.0 pp | | [HT-SAAE HT40-18X(ND)-F-320W](https://comparepv.com/panel/ht-saae-ht40-18x-nd-f-320w) | 320 W | -55 W, -2.1 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +275 W, lighter, +10.7 pp | --- Source: https://comparepv.com/panel/ht-saae-ht48-18x-nd-f-375w 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.
