The application of **half-cut technology with multiple busbars** minimizes resistive losses and enhances performance under partial shading - in practice, this means reduced power drops when shade from the chimney, trees, or window frames "cuts" across the module. The manufacturer also focuses on **lowering the risk of hotspots thanks to a special circuit design**, translating to a longer lifespan and greater peace of mind for the user. Another distinguishing feature is **enhanced resistance to PID**, which is particularly important in challenging grid conditions and humid environments. Completing the package is the **hermetic junction box with IP68 rating**, which supports reliability for years. This is a good choice for pitched and flat roofs, carports, and projects where fast installation and high module work ethic matter. ## Notable figures - Efficiency of 20.2% is 0.8pp above the \*\*PERC 0-400W\*\* median (19.4%) - At 202.3 W/m² power density, this panel generates 7.9 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 - At 21.5 kg, weight matches the \*\*PERC 0-400W\*\* median - In the top 85% for efficiency among all PERC panels ## Questions ### Do Talesun TP7F54M panels handle partial shading well, e.g. from a chimney or antenna? Yes, the TP7F54M series uses half-cut cell technology with multiple busbars, which reduces current losses under partial shading. When shade falls on only part of the module, the overall power drop is smaller than with traditional full-cell designs, and the risk of overheating in the shaded area is limited thanks to the split circuit layout. ### What warranty comes with Talesun TP7F54M panels and what does it cover? The manufacturer provides a 12-year product warranty and a 25-year linear power performance warranty. The product warranty covers material and workmanship defects, such as issues with the laminate or junction box, while the power warranty guarantees that the panel still produces a specified percentage of its original output after years of use. ### Is the Talesun TP7F54M series resistant to PID and suitable for humid climates? Yes, TP7F54M modules feature enhanced resistance to PID (Potential Induced Degradation), which typically occurs under high humidity and high system voltage. This helps the panels maintain stable performance even in harsher weather conditions, which matters for coastal installations or large systems with long strings. ### Are Talesun TP7F54M panels suitable for pitched and flat roofs, such as carports? Yes, the 108-cell half-cut format in a standard frame makes the TP7F54M series suitable for pitched residential roofs as well as flat roofs and carport structures. The sealed IP68 junction box ensures resistance to moisture and dust regardless of mounting angle, and the sturdy build makes installation on typical mounting systems straightforward. ### Is the Talesun TP7F54M series still available for purchase? The TP7F54M / TP7F54M(H) series has been discontinued from current production by Talesun and replaced with newer, higher-power, higher-efficiency models. Panels may still be available from distributors as remaining stock, so it's worth checking current availability with your supplier and considering the manufacturer's newer series for new installations. ### What is the maximum power and efficiency of the Talesun TP7F54M 415 Wp module? The top variant of the series reaches a maximum power of 415 Wp using monocrystalline PERC cells with half-cut technology. This is a strong result for a 108-cell format panel, translating to a module efficiency above 21%, allowing more energy yield from the same roof area compared to older designs without cell splitting. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/BISTAR-TP7F54MTP7F54MH-Anti-glare-20220301-EN-4e899474999d.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 | Cooler, +2.9 pp, +5 yr warranty | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | Lighter, +2.8 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, +2.8 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, +2.8 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, +2.8 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, +2.8 pp, +5 yr warranty | | [Jetion JT440SYK(B)](https://comparepv.com/panel/jetion-jt440syk-b) | 440 W | Cooler, +2.7 pp, +5 yr warranty | | [Luxor Solar LX-440M/182-108+](https://comparepv.com/panel/luxor-solar-lx-440m-182-108) | 440 W | +45 W, cooler, +2.7 pp | | [Talesun TP7F54M-390W](https://comparepv.com/panel/talesun-tp7f54m-390w) | 390 W | Very close match | | [Talesun TP7F54M-400W](https://comparepv.com/panel/talesun-tp7f54m-400w) | 400 W | +0.3 pp | | [Talesun TP7F54M-405W](https://comparepv.com/panel/talesun-tp7f54m-405w) | 405 W | +10 W, +0.5 pp | | [Talesun TP7G54M/410W](https://comparepv.com/panel/talesun-tp7g54m-410w) | 410 W | +15 W, +0.8 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +115 W, cooler, +4.8 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +100 W, cooler, +4.6 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +110 W, cooler, +4.5 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +95 W, cooler, +4.3 pp | --- Source: https://comparepv.com/panel/talesun-tp7f54m-395w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
