Thanks to its **bifacial construction**, the module can operate not only from the front side but also utilize light reflected from the ground-practical in white roofs, carports, and ground-mounted installations. The application of **N-type TOPCon cell technology** translates to more stable performance in high temperatures and better parameter retention over the long term, crucial for investment profitability. The **dual glass** structure with double glazing increases resistance to moisture and environmental factors, and **enhanced PID resistance** minimizes the risk of power degradation in demanding conditions. This is an excellent choice for installers and investors seeking modules for flat roofs, PV farms, awnings, and projects in windy, dusty, and variable weather conditions. ## Notable figures - At 22.8% efficiency, this panel is on par with typical \*\*TOPCon 500-550W\*\* modules - At 227.6 W/m² power density, roof space requirements are typical for \*\*TOPCon 500-550W\*\* panels - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 500-550W\*\* panels - At 28.1 kg, this panel is 1.1 kg heavier than the \*\*TOPCon 500-550W\*\* median (27.0 kg) - more demanding for installation crews - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof ## Questions ### What is the maximum power output of the Talesun BIPRO TM3G54M solar panel? Panels in the BIPRO TM3G54M series reach a maximum power output of up to 510 Wp. This is achieved through 108 high-efficiency N-type TOPCon cells combined with a bifacial design that captures additional reflected light from the ground, boosting real-world energy yield compared to standard monofacial modules of similar dimensions. ### How does the TOPCon cell technology in the Talesun BIPRO TM3G54M differ from standard PERC cells? N-type TOPCon cells offer lower power degradation over time and better performance stability at high temperatures compared to conventional PERC cells. As a result, the Talesun BIPRO TM3G54M maintains higher efficiency during hot summer conditions and in sunny regions, translating into higher overall energy yield across the system's operating lifetime. ### Is the Talesun BIPRO TM3G54M suitable for flat roofs or carport installations? Yes, thanks to its bifacial design and dual glass construction, the BIPRO TM3G54M series performs well on flat roofs, carports, and ground-mount installations where the rear side of the module can capture light reflected from a bright surface. In such setups, the bifacial power gain typically ranges from several to over ten percent compared to monofacial panels. ### What warranty does the Talesun BIPRO TM3G54M come with? The manufacturer provides a 15-year product warranty and a 30-year linear power output warranty. This means the panel is guaranteed to maintain a minimum level of energy production over three decades, which is an important factor when calculating the long-term return on investment of a solar installation. ### Does the dual glass construction of the Talesun BIPRO TM3G54M improve durability and moisture resistance? Yes, the dual glass design replaces the standard rear backsheet with a second layer of tempered glass, significantly improving the module's sealing and reducing moisture ingress into the laminate. This results in greater resistance to PID degradation and more stable long-term performance, especially in installations exposed to wind, dust, and variable weather. ### Is it worth choosing bifacial Talesun BIPRO TM3G54M panels over cheaper monofacial panels? Bifacial panels come at a higher upfront cost, but under the right conditions - bright roofs, ground-mount systems, or surfaces with high light reflectance - they generate extra energy from the rear side of the module, shortening the investment payback period. Combined with TOPCon technology and a 30-year power warranty, the BIPRO TM3G54M series is a solid choice for installations aiming to maximize yield on limited surface area. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/bipro-tm3g54m-16bb-black-frame-20240508-en-81a4f128eea9.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +2.2 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +2.0 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +50 W, lighter, +2.0 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +1.9 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +45 W, lighter, +1.8 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +1.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +1.7 pp | | [Talesun TM3G54M/490W](https://comparepv.com/panel/talesun-tm3g54m-490w) | 490 W | -20 W, -0.9 pp | | [Talesun TM3G54M/495W](https://comparepv.com/panel/talesun-tm3g54m-495w) | 495 W | -15 W, -0.7 pp | | [Talesun TM3G54M/500W](https://comparepv.com/panel/talesun-tm3g54m-500w) | 500 W | -10 W, -0.5 pp | | [Talesun TM3G54M/505W](https://comparepv.com/panel/talesun-tm3g54m-505w) | 505 W | -0.3 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +40 W, lighter, +1.6 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +30 W, lighter, +1.6 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +30 W, lighter, +1.6 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | +35 W, cooler, +1.5 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | +35 W, lighter, +1.4 pp | --- Source: https://comparepv.com/panel/talesun-tm3g54m-510w Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
