This directly translates into more kWh per m² of roof or ground area. - **15-year product warranty - above segment norm** - The series carries a 15-year product and workmanship warranty, compared to only 12 years for the direct peer GCL SIROT NT10/72GDF. The extended coverage reduces O&M risk and compresses the discount rate when modeling LCOE for commercial projects. - **N-type TOPCon: low LID and degradation** - N-type TOPCon cells eliminate the LID losses typical of PERC. The industry-standard TOPCon degradation curve guarantees ≤1% first-year loss and ≤0.4%/year for years 2-30, ensuring ≥87.4% of nominal power after 30 years - in line with GCL and Trina Solar offerings at this module class. - **Double glass and bifacial in a single design** - A glass-glass encapsulation improves resistance to moisture ingress, micro-cracks, and cyclic snow loads - critical for the Polish climate. The bifacial design captures rear-side irradiance: ground-mount installations on high-albedo surfaces typically yield 5-15% additional annual energy output at no incremental module cost. - **Half-cut cells - reduced hotspot risk** - Splitting cells in half reduces series resistance by roughly 50% and limits hotspot formation under partial shading. The series maintains predictable output on commercial rooftops with obstacles (chimneys, antennas, skylights), which is important for projects with non-uniform shading profiles. ## Cons - **Not on current BNEF Tier 1 list** - Manufacturer Huayao does not appear on the BNEF Tier 1 module list as of Q1 2026 - having been present in Q1 2025, the company lost its bankable status after BNEF raised the eligibility threshold to projects of at least 10 MW financed by independent commercial banks. The absence of Tier 1 / bankable status may complicate project-finance arrangements for utility-scale PV assets above 1 MW and increase risk premiums in insurance and leasing structures. ## About this series The Huayao TCL Solar Half Cut N-type Bifacial Double Glass Module (G10L-72P) series are modules designed for maximum performance under real-world conditions - not just in a laboratory. The use of **N-type solar cells in TOPCon technology** minimizes typical power losses associated with LID degradation and helps maintain stable energy production over the years. The **bifacial** design allows for the recovery of additional light from the rear side, which translates to better performance, especially on bright roofs, ground-mounted structures, and with appropriate substrates. A key advantage of this series is **double glass**, which increases resistance to moisture, microcracks, and weather-related stresses - this is particularly important in the Polish climate, where snow, wind, and frequent temperature changes are factors. The **half cut** design improves performance under partial shading and reduces the risk of hot spots, making the installation more predictable. This is a good choice for investors in PV farms, commercial roofs, and demanding projects where durability, safety, and high energy yield are important. ## Notable figures - At 22.8% efficiency, this panel is on par with typical \*\*TOPCon 550-600W\*\* modules - 228.4 W/m² power density - 4.0 W/m² more than \*\*TOPCon 550-600W\*\* median (224.4 W/m²), more power per roof area - Temperature coefficient of -0.28%/°C matches the \*\*TOPCon 550-600W\*\* median - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface - #2769 for efficiency, #1347 for temperature performance out of 14129 panels ## Questions ### What warranty does the Huayao TCL Solar G10L-72P come with? The G10L-72P series includes a 15-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty. Thanks to N-type TOPCon cell technology, LID-related power degradation is significantly lower than with older PERC cells, making the power warranty a meaningful long-term guarantee rather than a formality. ### Does the bifacial design of the Huayao TCL Solar G10L-72P make sense for a ground-mounted solar farm? Yes, provided the system is properly designed. The G10L-72P captures light from both the front and rear sides. On ground-mounted systems with reflective surfaces such as sand, concrete, or snow, rear-side gain can add several to over ten percent in additional energy yield. Adequate module clearance above ground and avoiding rear shading are essential for maximizing bifacial performance. ### What does the half-cut cell design in the G10L-72P mean for partial shading situations? Half-cut cells are laser-cut into two halves, reducing internal resistance and limiting the impact of shading on overall output. If part of a G10L-72P module is shaded by a chimney or cable, only the affected cell section loses output rather than the entire string. This makes half-cut technology a meaningful advantage in real-world installations where perfect irradiation throughout the day is rarely guaranteed. ### Why does the G10L-72P use double glass instead of a backsheet, and is there a higher risk of breakage? The double glass construction replaces a polymer backsheet with a second tempered glass layer, offering better resistance to moisture ingress, micro-cracks, and mechanical loads from snow and wind. Tempered glass is more durable long-term than polymer films, especially under repeated temperature cycling. Breakage risk is minimized by the tempering process, making double glass modules a reliable choice for demanding climates. ### What is the peak power output of the Huayao TCL Solar G10L-72P and what applications is it designed for? The G10L-72P achieves up to 605 Wp peak power, placing it firmly in the commercial and utility-scale category. It is designed for ground-mounted solar farms, large commercial rooftops, and demanding projects where high energy yield per square meter and long-term reliability are the primary criteria. For small residential rooftops, a lower-wattage module in a smaller form factor would typically be a better fit. ### Is Huayao a Tier 1 manufacturer, and does that matter when evaluating this panel? Huayao is not currently listed as a Tier 1 manufacturer by agencies such as Bloomberg NEF. This does not necessarily indicate poor product quality, but it is a relevant risk factor for projects financed through loans or leasing, where bankability matters. Before purchasing, it is advisable to verify authorized service availability in your region and confirm the manufacturer's current financial standing. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/68ff51d2fdf03ff7c538b23c_TCL-TC-580600-72-Wht-GG-Com-0d82f96d9cf0.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -30 W, lighter, +2.0 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +50 W, lighter, +2.0 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -35 W, lighter, +1.8 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +45 W, lighter, +1.8 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +40 W, cooler, +1.6 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | -40 W, lighter, +1.6 pp | | [Huayao HY535-M144BDD](https://comparepv.com/panel/huayao-hy535-m144bdd) | 535 W | -55 W, hotter, -2.1 pp | | [Huayao HY540-M144BDD](https://comparepv.com/panel/huayao-hy540-m144bdd) | 540 W | -50 W, hotter, -1.9 pp | | [Huayao HY545-M144BDD](https://comparepv.com/panel/huayao-hy545-m144bdd) | 545 W | -45 W, hotter, -1.7 pp | | [Huayao HY550-M144BDD](https://comparepv.com/panel/huayao-hy550-m144bdd) | 550 W | -40 W, hotter, -1.5 pp | | [Huayao HY555-M144BDD](https://comparepv.com/panel/huayao-hy555-m144bdd) | 555 W | -35 W, hotter, -1.3 pp | | [Huayao HY570-N144BDD](https://comparepv.com/panel/huayao-hy570-n144bdd) | 570 W | -20 W, hotter, -0.7 pp | | [Huayao HY575-N144BDD](https://comparepv.com/panel/huayao-hy575-n144bdd) | 575 W | -15 W, hotter, -0.5 pp | | [Huayao HY580-N144BDD](https://comparepv.com/panel/huayao-hy580-n144bdd) | 580 W | -10 W, hotter, -0.4 pp | | [Huayao HY585-N144BDD](https://comparepv.com/panel/huayao-hy585-n144bdd) | 585 W | Hotter | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +60 W, lighter, +2.4 pp | --- Source: https://comparepv.com/panel/huayao-hsm-nd72-gf590 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.
