Its key advantage is the **bifacial dual-glass structure**, enabling efficient utilization of reflected light from the ground - a real benefit for flat roofs, carports, and PV farms with light gravel or membrane. Modules are based on **N-type TOPCon cells**, ensuring better performance in low light conditions and greater stability over the long term. The application of **half-cut technology** improves resilience to partial shading and minimizes internal losses, benefiting installations with complex roof geometries. Enhanced resistance to degradation and **high PID resistance** increase investment safety in high-humidity conditions. This series is particularly recommended for commercial and industrial projects, where lower energy costs and predictable long-term production are top priorities. ## Notable figures - Efficiency of 22.8% matches the \*\*TOPCon 550-600W\*\* median - At 228.4 W/m² power density, this panel generates 4.0 W/m² more per unit area than \*\*TOPCon 550-600W\*\* median (224.4 W/m²) - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 550-600W\*\* panels - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces - Ranked #2714 out of 14005 panels for efficiency in the database ## Questions ### How much extra energy do I actually gain from the bifacial design of Talesun TM7G72M panels? The rear-side gain depends on the ground surface and mounting height - on light gravel, a white roof membrane, or snow you can realistically expect a few to low-teens percent more energy than a mono-facial panel, while the manufacturer states up to 30% extra yield under ideal conditions. Flat roofs, carports, and ground-mount PV farms with elevated racking benefit the most. ### What is N-type TOPCon technology in Talesun panels, and is it worth paying more for? TOPCon cells use N-type silicon and, compared to the widely used PERC technology, offer higher efficiency (up to 22.80% in this series), slower degradation over time (under 1% in the first year and a maximum of 0.4% per year afterward), and better performance under weak or diffuse light. For installations planned for 25-30 years of operation, this is a real advantage over older cell technologies. ### What warranty comes with Talesun TM7G72M (BIPRO) panels? The manufacturer provides a 12-year product warranty against manufacturing defects and a 30-year linear power warranty, which is standard for modern N-type TOPCon modules. Talesun is a Tier 1 manufacturer, so the warranty is backed by the company's financial stability - an important factor for bank financing on larger commercial installations. ### Are TM7G72M panels suited for flat roofs, carports, or utility-scale PV farms? This series performs best wherever the panel can be mounted with clearance above a reflective surface - flat roofs, carports, and ground-mount PV farms with light-colored gravel or membrane. The half-cut, 144-cell layout and 590 Wp power rating also work well with the wider string spacing typical of commercial and industrial sites. ### Are Talesun BIPRO panels hail-resistant and suitable for harsh weather? Yes, the modules feature a reinforced 3.2 mm tempered front glass, tested against 55 mm hailstones at 33.9 m/s, making them suitable for regions with frequent hailstorms. The dual-glass construction also improves mechanical stiffness and adds better moisture and PID resistance compared to panels with a standard backsheet. ### Is Talesun a bankable, trustworthy manufacturer for a large commercial investment? Talesun is a Tier 1 manufacturer headquartered in China with many years of presence in the PV market, which makes bank financing and insurance for installations easier to secure. The TM7G72M series is not discontinued, so module availability and spare-part supply should remain stable in the coming years - relevant for long-term service planning. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/bipro-tm7g72m-16bb-30mm-frame-20240322-en-d796db1b3660.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, 16 kg lighter, +1.6 pp | | [Talesun TP7F72M-530W](https://comparepv.com/panel/talesun-tp7f72m-530w) | 530 W | -60 W, hotter, -2.3 pp | | [Talesun TP7F72M-535W](https://comparepv.com/panel/talesun-tp7f72m-535w) | 535 W | -55 W, hotter, -2.1 pp | | [Talesun TP7F72M-540W](https://comparepv.com/panel/talesun-tp7f72m-540w) | 540 W | -50 W, hotter, -1.9 pp | | [Talesun TP7F72M-545W](https://comparepv.com/panel/talesun-tp7f72m-545w) | 545 W | Hotter, -1.7 pp, -5 yr warranty | | [Talesun TP7F72M-550W](https://comparepv.com/panel/talesun-tp7f72m-550w) | 550 W | Hotter, -1.5 pp, -5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +60 W, lighter, +2.4 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +55 W, lighter, +2.2 pp | --- Source: https://comparepv.com/panel/talesun-tm7g72m-590w 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.
