The application of **bifacial construction** allows for additional energy gain from reflected radiation (albedo), which performs exceptionally well on light roofs, membranes, gravel, or ground installations. Variants with **half-cut technology** better tolerate partial shading and minimize string performance losses, aiding more stable energy production in typical Polish conditions (chimneys, window frames, trees). The module relies on **monocrystalline cells** and ensures long-term durability through solutions aimed at minimizing degradation and resistance to phenomena such as PID. An additional advantage is the **sealant-filled junction box IP68**, crucial for moisture, dust, and intensive operation. This is the premium series for residential, C&I, and utility-scale farms, where performance, reliability, and predictable operation are top priorities. ## Notable figures - Efficiency of 21.0% matches the \*\*PERC 400-450W\*\* median - 210.0 W/m² power density - 3.8 W/m² more than \*\*PERC 400-450W\*\* median (206.2 W/m²), more power per roof area - Temperature coefficient of -0.35%/°C matches the \*\*PERC 400-450W\*\* median - Bifaciality factor of 70% can add 4-10% extra yield with reflective mounting surface - #9758 for efficiency, #10419 for temperature performance out of 14005 panels ## Questions ### Is the Talesun TP7G54M 108-cell (BIPRO) series still available for purchase? No, this series has been discontinued from Talesun's current production lineup and replaced by newer models. Units may still appear at distributors as remaining stock, but availability is limited and inconsistent. For larger installations, it's worth confirming actual stock levels and production batch consistency with the seller beforehand. ### How does the bifacial TP7G54M panel differ from a standard monofacial panel? The TP7G54M generates power from both sides of the module thanks to a transparent rear layer, capturing light reflected off the ground (albedo). In practice this means extra energy yield, especially on light-colored roofs, membranes, or ground-mount installations over gravel or grass. A monofacial panel only produces electricity from its front side, so at the same 410 Wp nominal rating a bifacial installation can deliver higher real-world annual output. ### What warranty comes with the Talesun TP7G54M 108-cell modules? The series carries a 25-year product warranty and a 25-year power warranty, a premium standard among tier 1 manufacturers. This means Talesun covers both material and workmanship defects and guarantees the module maintains its rated power over a long operating period. It's still worth verifying warranty service terms with the seller, since the series has already been discontinued. ### Does half-cut cell technology in the TP7G54M help with partial shading? Yes, half-cut cells, split down the middle, reduce power losses under partial shading, for example from a chimney, dormer window, or nearby tree. Splitting the cells limits the impact of a shaded section on the entire module string, so the panel loses less energy than a traditional full-cell design in typical Polish roof conditions. ### Are Talesun TP7G54M panels suitable for a pitched roof on a single-family home? Yes, the BIPRO series works well for single-family homes as well as C&I installations and solar farms. On pitched roofs the bifacial gain is smaller than in ground-mount setups, but it still delivers additional yield, especially with light-colored roofing. Half-cut technology further helps in the typical partial-shading conditions common on residential roofs. ### What does IP68 junction box rating mean on the TP7G54M module and why does it matter? IP68 protection means the junction box is fully dust-tight and rated for prolonged submersion in water, a higher standard than the common IP65 or IP67 ratings. This matters for installations exposed to moisture, heavy rainfall, or dust, such as solar farms or agricultural sites, where electrical connections face a greater risk of degradation over time. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/390-410-tp7g54m-transparent-bs-25-us-098ddebb8964.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A460-MAH54Mb](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a460-mah54mb-1) | 460 W | +50 W, cooler, +2.6 pp | | [Just Solar JST-EDMH-(445-465)W-TD (460W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-460w-class) | 460 W | +50 W, +2.6 pp, +5 yr warranty | | [Luxor Solar LX-460M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-460m-182r-96-gg) | 460 W | +50 W, cooler, +2.6 pp | | [Philadelphia Solar PS-MNB108(HCBF)-460W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-460w) | 460 W | +50 W, cooler, +2.5 pp | | [JA Solar JAT54S40-460/LR](https://comparepv.com/panel/ja-solar-jat54s40-460-lr) | 460 W | +50 W, cooler, +2.5 pp | | [Luxor Solar LX-460M/182R188-108+ GG](https://comparepv.com/panel/luxor-solar-lx-460m-182r188-108-gg) | 460 W | +50 W, cooler, +2.4 pp | | [AIKO AIKO-455-MAH54Db](https://comparepv.com/panel/aiko-aiko-455-mah54db) | 455 W | Cooler, +2.3 pp, +5 yr warranty | | [Longi Solar LR5-54HTH-455M](https://comparepv.com/panel/longi-lr5-54hth-455m) | 455 W | +45 W, cooler, +2.3 pp | | [Talesun TP7F54M-390W](https://comparepv.com/panel/talesun-tp7f54m-390w) | 390 W | -20 W, -1.0 pp | | [Talesun TP7F54M-395W](https://comparepv.com/panel/talesun-tp7f54m-395w) | 395 W | -15 W, -0.8 pp | | [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 | -0.3 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +100 W, cooler, +4.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +85 W, cooler, +3.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +95 W, cooler, +3.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +80 W, cooler, +3.5 pp | --- Source: https://comparepv.com/panel/talesun-tp7g54m-410w 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.
