The use of a **bifacial construction** allows for the utilization of reflected light from the ground, which significantly improves energy production in ground-mounted systems, on bright roofs, and on carport structures. The modules are based on **N-type cells using TOPCon technology**, which improves their ability to handle typical operational losses and maintain high efficiency for longer periods. Another key feature is the **dual-glass design**, which increases resistance to moisture and stress, and reduces the risk of micro-cracks during transport and installation. Additionally, the **half-cut technology with multiple busbars** improves performance under partial shading and stabilizes parameters in more challenging conditions. This makes it a good choice for PV farms, commercial projects, and modern industrial installations, where durability, predictable energy yields, and lower long-term energy costs are important. ## Notable figures - Efficiency of 23.0% is 0.6pp above the \*\*TOPCon 550-600W\*\* median (22.4%) - At 230.3 W/m² power density, this panel generates 5.9 W/m² more per unit area than \*\*TOPCon 550-600W\*\* median (224.4 W/m²) - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 550-600W\*\* panels - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface - #1744 for efficiency, #6093 for temperature performance out of 14005 panels ## Questions ### How does the Tata Power Solar GSD7S72T series differ from standard monofacial panels? The key difference is the bifacial design – the panel generates power from both the front and rear sides, capturing light reflected off the ground. On light-colored surfaces such as gravel or white rooftops, this can add several extra percentage points of energy yield compared to a monofacial module rated at the same 595 Wp. ### What is TOPCon technology in the GSD7S72T and does it actually improve output? TOPCon uses N-type cells that reduce recombination losses, delivering higher efficiency than older P-type PERC cells. In practice this means better performance at high temperatures, lower power degradation over time, and more stable energy yield throughout the system's lifetime. ### What warranty comes with the Tata Power Solar GSD7S72T panels? The manufacturer provides a 25-year product warranty and a 30-year power output warranty. This gives long-term coverage against material and workmanship defects as well as assurance that the module maintains its rated efficiency, supporting a predictable LCOE over the system's service life. ### Does the dual glass construction in the GSD7S72T affect durability and weight? The dual glass design increases resistance to moisture and PID degradation and improves mechanical load tolerance while reducing the risk of cell microcracks during transport and installation. The panel is somewhat heavier than a backsheet version, so this should be factored in when selecting a mounting structure, especially on roofs with limited load capacity. ### What installation types is the GSD7S72T series best suited for? Thanks to its bifacial design and high 595 Wp rating, the panel performs particularly well in ground-mounted PV farms, carport installations, and light-colored flat roofs, where reflected light can be captured by the rear side. It's a strong fit for commercial and industrial projects focused on maximizing yield per square meter. ### Does the half-cut, multi-busbar cell technology in the GSD7S72T help with partial shading? Yes, splitting cells into halves (half-cut) combined with a denser busbar grid reduces current losses and limits the impact of partial shading, such as from chimneys or adjacent panel rows. This keeps the array performing more consistently under less-than-ideal light conditions. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/gsd7s72t-595wt-bifacial-dual-glass-16bb-half-cut-mono-topcon-5e745c01a967.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +50 W, lighter, +2.0 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +1.8 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +45 W, lighter, +1.8 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -40 W, lighter, +1.6 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +40 W, lighter, +1.6 pp | | [Tata Power Solar TP540HG10B-530](https://comparepv.com/panel/tata-power-solar-tp540hg10b-530) | 530 W | -65 W, hotter, -2.5 pp | | [Tata Power Solar TP540HG10B-535](https://comparepv.com/panel/tata-power-solar-tp540hg10b-535) | 535 W | -60 W, hotter, -2.3 pp | | [Tata Power Solar TP540HG10B-540](https://comparepv.com/panel/tata-power-solar-tp540hg10b-540) | 540 W | -55 W, hotter, -2.1 pp | | [Tata Power Solar TP545HG10TB](https://comparepv.com/panel/tata-power-solar-tp545hg10tb) | 545 W | -50 W, hotter, -1.9 pp | | [Tata Power Solar TP550HG10TB](https://comparepv.com/panel/tata-power-solar-tp550hg10tb) | 550 W | Hotter, -1.7 pp, -5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +55 W, lighter, +2.2 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +35 W, cooler, +1.4 pp | --- Source: https://comparepv.com/panel/tata-power-solar-gsd7s72t-595wt 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.
