Its key advantage is the **bifacial construction**, which harnesses reflected light from the ground, significantly boosting energy production in ground-mounted installations, on light-colored roofs, and in gravel or concrete surroundings. The applied **TOPCon N-type cell technology** supports high efficiency and good resistance to common degradation mechanisms, ensuring the module maintains predictable performance for years. Equally noteworthy is the **half-cut technology with dense busbar layout (16BB)**, which improves performance under partial shading and lower irradiance - crucial for Polish conditions. This is complemented by **enhanced PID resistance** and solutions that increase durability in humid, windy, and dusty environments. This is an excellent choice for PV farms, large industrial rooftops, and projects where the goal is to achieve low energy costs over the entire lifetime. ## Notable figures - Efficiency of 22.6% matches the \*\*TOPCon 600-650W\*\* median - Power density of 225.8 W/m² matches the \*\*TOPCon 600-650W\*\* median - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 600-650W\*\* panels - At 33.8 kg, this panel is 1.1 kg heavier than the \*\*TOPCon 600-650W\*\* median (32.7 kg) - more demanding for installation crews - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof ## Questions ### Are the bifacial Talesun TM9G72M panels suitable for ground-mount installations and light-colored roofs? Yes, this is one of the series' main use cases. The bifacial construction captures light reflected from the ground, so on ground-mount solar farms, roofs covered with light membranes, or surfaces surrounded by gravel or concrete, the additional energy yield can reach several to over a dozen percent compared to a monofacial module. The lighter and more reflective the surface, the higher the gain from the rear side of the panel. ### What warranty comes with Talesun TM9G72M modules? The manufacturer provides a 12-year product warranty covering material and workmanship defects, plus a 30-year power output warranty, which is standard for modern TOPCon panels. This guarantees a minimum energy production level over three decades, with a gradual, predictable efficiency decline. It's a key factor when calculating investment payback over a 25-30 year horizon. ### How does the TOPCon technology in the Talesun TM9G72M differ from older PERC cells? N-type TOPCon cells have higher base efficiency and lower first-year power degradation than conventional P-type PERC cells. An extra passivation layer reduces electron recombination, improving performance at higher temperatures and slowing long-term degradation. In practice, this means a higher energy yield from the same roof area over the module's entire lifespan. ### Do Talesun TM9G72M panels perform well under partial shading, for example from a chimney or antenna? Yes, thanks to half-cut cell technology and dense 16-busbar routing, the module is electrically divided into smaller sections, so shading on one part has a smaller impact on the whole string's output. This reduces power losses from spot shading and improves production on overcast days, which matters especially under Central European sunlight conditions. ### What are the dimensions and weight of the Talesun TM9G72M 620W panel? The 620W module measures approximately 2382 x 1134 x 30 mm and weighs about 33.8 kg. It's a large, heavy 144-cell panel intended mainly for ground-mount installations and large industrial roofs, where the mounting structure needs to be properly sized for its dimensions and mass. ### Is Talesun a reliable manufacturer choice for a large-scale PV installation? Talesun is a Tier 1 manufacturer headquartered in China, offering financial stability, extensive manufacturing experience, and reliable warranty backing even for large-scale projects. Combined with TOPCon technology, bifacial construction, and enhanced PID resistance, the TM9G72M series is a solid choice for solar farms and large industrial roofs where lowest lifetime energy cost is the priority. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/bipro-tm9g72m-16bb-30mm-frame-20240524-en-22b74e5f1233.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +40 W, lighter, +2.6 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +35 W, lighter, +2.4 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -50 W, lighter, +2.2 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +30 W, lighter, +2.2 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | Cooler, lighter, +2.0 pp | | [Longi Solar LR8-66HVD-660M](https://comparepv.com/panel/longi-lr8-66hvd-660m) | 660 W | +50 W, cooler, +1.8 pp | | [Talesun TM3G66M-600](https://comparepv.com/panel/talesun-tm3g66m-600) | 600 W | -10 W, -0.4 pp | | [Talesun TM3G66M-605](https://comparepv.com/panel/talesun-tm3g66m-605) | 605 W | -0.2 pp | | [Talesun TM9G72M-615W](https://comparepv.com/panel/talesun-tm9g72m-615w) | 615 W | Very close match | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +70 W, lighter, +2.6 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +65 W, lighter, +2.4 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +90 W, cooler, +2.4 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +85 W, cooler, +2.3 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +60 W, lighter, +2.2 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +60 W, lighter, +2.2 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +60 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/talesun-tm9g72m-610w 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.
