A key advantage is its **glass-glass** construction, which better protects the solar cells from moisture, micro-cracks, and material degradation compared to typical modules with a backsheet. This is a good choice for investors who want to minimize the risk of declining yields over the long term. The module utilizes **bifacial technology** and **monocrystalline PERC cells**, allowing it to better utilize reflected light from the ground and improve energy production under suitable conditions. In practice, this helps to increase profitability, especially on bright roofs, ground-mounted structures, and carport structures. An additional advantage is the **enhanced mechanical strength** resulting from the double-pane glass, which installers will appreciate, especially with larger module formats. The TP540HG10B series is designed for prosumers and companies that expect predictable yields, high durability, and reliable performance in the Polish climate. ## Notable figures - Efficiency of 20.7% matches the \*\*PERC 500-550W\*\* median - At 207.1 W/m² power density, roof space requirements are typical for \*\*PERC 500-550W\*\* panels - Temperature coefficient of -0.37%/°C is 0.02pp worse than \*\*PERC 500-550W\*\* median (-0.35%/°C) - higher losses in summer heat - At 33.0 kg (4.6 kg above \*\*PERC 500-550W\*\* median of 28.4 kg), requires checking roof load capacity - Bifacial design (70% factor) captures reflected light - adds 4-10% yield on ground-mount or white roof ## Questions ### What is the maximum power output of the Tata Power Solar TP540HG10B (Glass - Glass) module? The module delivers up to 550 Wp of maximum power, within the 530-550 Wp production range typical for this series. It is built with 144 monocrystalline PERC cells, and the glass-glass construction allows it to achieve efficiency above 20% while keeping a relatively compact footprint for its power class. ### How does a glass-glass construction differ from a standard backsheet panel? In a glass-glass module, the cells are sandwiched between two glass sheets instead of glass and a PET backsheet. This makes the panel significantly more resistant to moisture ingress, microcracks, and laminate degradation over time, resulting in more stable long-term performance. It's a good choice when minimizing output loss risk over decades of operation is a priority. ### Is the TP540HG10B worth it for ground-mount and carport installations thanks to bifacial technology? Yes, bifacial technology lets the rear side of the module capture light reflected off the ground, which works especially well over light-colored gravel, concrete, or roofing membranes, as well as in ground-mount and carport arrays with sufficient clearance. Under favorable conditions, the rear-side energy gain can range from a few percent up to the low double digits, depending on mounting height and ground albedo. ### What warranty does the TP540HG10B series come with - product and power? The series is covered by a 12-year product warranty against material and workmanship defects, plus a 30-year linear power output warranty. This means the manufacturer guarantees a high percentage of nominal power retention even after three decades of operation, which is a key factor when calculating long-term system profitability. ### Is Tata Power Solar a reliable Tier 1 manufacturer, and where are the panels made? Yes, Tata Power Solar is classified as a Tier 1 manufacturer, meaning it has a documented track record of financial stability, large-scale production, and bankability recognized by financing institutions. Its manufacturing facilities and headquarters are based in India, and the brand is part of the Tata Group, one of India's largest and longest-standing industrial conglomerates. ### Does the TP540HG10B perform well in winter and low temperatures? Yes, the module has a power temperature coefficient of -0.37%/°C, meaning a relatively small output drop as temperature rises and correspondingly better performance in cooler conditions than STC ratings alone would suggest. In practice, cold Polish winters with snow reflecting light can even boost instantaneous output, especially through additional rear-side gain from the bifacial design. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/tp540hg10b-glass-glass-2b14e2338e4e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +4.3 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +4.1 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +4.1 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +4.0 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +3.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +3.8 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +3.8 pp | | [Tata Power Solar TP540HG10B-530](https://comparepv.com/panel/tata-power-solar-tp540hg10b-530) | 530 W | Very close match | | [Tata Power Solar TP540HG10B-540](https://comparepv.com/panel/tata-power-solar-tp540hg10b-540) | 540 W | Very close match | | [Tata Power Solar TP545HG10TB](https://comparepv.com/panel/tata-power-solar-tp545hg10tb) | 545 W | Lighter, +0.4 pp, -5 yr warranty | | [Tata Power Solar TP550HG10TB](https://comparepv.com/panel/tata-power-solar-tp550hg10tb) | 550 W | Lighter, +0.6 pp, -5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +115 W, cooler, +4.5 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +110 W, cooler, +4.3 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +105 W, cooler, +4.1 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +100 W, cooler, +3.9 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +95 W, cooler, +3.7 pp | --- Source: https://comparepv.com/panel/tata-power-solar-tp540hg10b-535 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.
