Its standout feature is the **full black appearance**, enabling the modules to blend seamlessly with modern homes, premium roofs, and commercial buildings without the random mottled effect. The application of **half-cut technology with multiple busbars** improves performance under partial shading and minimizes losses due to internal resistances, leading to more predictable yields in real-world conditions. The manufacturer also highlights **reduced risk of hot-spots** thanks to the optimized electrical structure and **enhanced PID resistance**, which is crucial for long-term operation. The entire system is complemented by a **IP68 junction box**, increasing safety in humid and variable climates. This is an excellent choice for those seeking high module performance, robust reliability, and a sleek, black, elegant roof appearance. ## Notable figures - At 20.0% efficiency, this panel is 0.6pp above typical \*\*PERC 0-400W\*\* modules (median: 19.4%) - At 199.7 W/m² power density, this panel generates 5.3 W/m² more per unit area than \*\*PERC 0-400W\*\* median (194.4 W/m²) - Temperature coefficient of -0.35%/°C matches the \*\*PERC 0-400W\*\* median - Weight of 21.5 kg is typical for \*\*PERC 0-400W\*\* panels - In the top 87% for efficiency among all PERC panels ## Questions ### What is the maximum power output of Talesun BISTAR TP7F54M Full Black panels? The BISTAR TP7F54M / TP7F54M(H) Full Black series reaches up to 390 Wp of maximum power, built with 108 half-cut PERC cells. Module efficiency falls around 20-21%, which is a solid result for a monocrystalline panel featuring a full-black coating that typically trades a bit of output for aesthetics. ### Are BISTAR TP7F54M panels suitable for roofs with heavy snow or wind loads? Yes, this series is tested for snow loads up to 5400 Pa and wind loads up to 2400 Pa, meeting requirements typical for demanding climates, including mountainous and coastal regions. The reinforced frame and construction allow safe installation on both pitched and flat roofs with an appropriate mounting system. ### What warranty comes with Talesun BISTAR TP7F54M Full Black panels? The manufacturer provides a 12-year product warranty and a 25-year power output warranty, ensuring a significant portion of initial power is retained after a quarter century of use. Talesun is a Tier 1 manufacturer headquartered in China, adding further confidence in long-term service support for the installation. ### What is the difference between the Full Black version and the standard TP7F54M? The Full Black version features a black frame and black backsheet instead of white, giving the entire module a uniform look from any distance. Electrical parameters, PERC technology, and construction remain identical to the standard version, so the choice mostly comes down to roof aesthetics and installer preference. ### Do BISTAR TP7F54M panels have protection against PID effect? Yes, modules in this series feature enhanced resistance to potential-induced degradation (PID), limiting power loss caused by leakage currents in installations with high system voltage, up to 1500V. An optimized electrical layout also reduces the risk of hot spots during long-term operation. ### Is the Talesun BISTAR TP7F54M / TP7F54M(H) Full Black series still available for purchase? This series has been discontinued from Talesun's current production lineup and replaced by newer models with higher power output and efficiency. Panels may still be available in limited quantities from distributors as remaining stock, so it's worth confirming current availability with a supplier before planning a larger installation based solely on this model. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/BISTAR-TP7F54MTP7F54MH-Black-20220301-EN-dc18c1cd5de8.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Luxor Solar LX-440M/182-108+GG](https://comparepv.com/panel/luxor-solar-lx-440m-182-108-gg) | 440 W | +50 W, cooler, +3.1 pp | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | -50 W, lighter, +3.0 pp | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | Lighter, +3.0 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | Lighter, +3.0 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/2\*4\*20)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-2-4-20) | 400 W | Lighter, +3.0 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/4\*4\*40)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-4-4-40) | 400 W | Lighter, +3.0 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/2\*4\*19)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19) | 380 W | Lighter, +3.0 pp, +5 yr warranty | | [Jetion JT440SYK(B)](https://comparepv.com/panel/jetion-jt440syk-b) | 440 W | +50 W, cooler, +2.9 pp | | [Talesun TP7F54M-395W](https://comparepv.com/panel/talesun-tp7f54m-395w) | 395 W | Very close match | | [Talesun TP7F54M-400W](https://comparepv.com/panel/talesun-tp7f54m-400w) | 400 W | +10 W, +0.5 pp | | [Talesun TP7F54M-405W](https://comparepv.com/panel/talesun-tp7f54m-405w) | 405 W | +15 W, +0.7 pp | | [Talesun TP7G54M/410W](https://comparepv.com/panel/talesun-tp7g54m-410w) | 410 W | +20 W, +1.0 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +120 W, cooler, +5.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +105 W, cooler, +4.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +115 W, cooler, +4.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +100 W, cooler, +4.5 pp | --- Source: https://comparepv.com/panel/talesun-tp7f54m-390w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
