By eliminating light-induced degradation and significantly minimizing energy losses, these modules offer **exceptional stability of electrical parameters** throughout the entire, long-term operational period of the system. The use of multi-busbar technology effectively improves current flow and clearly increases the cells' resistance to mechanical loads, which directly translates into a significantly lower risk of failure. Tangra M effectively solves the problem of limited installation space by offering **high power density**, which allows for generating the maximum amount of energy from a relatively smaller roof area. This series stands out from the competition with excellent performance in low solar irradiance conditions, providing **above-average yields on cloudy days**, which is a key feature in specific Polish weather conditions. Designed for conscious investors who value innovative solutions, it ensures **investment security and a quick return** on costs thanks to record-low temperature coefficients. Choosing this series is a reliable guarantee of durability, where the reinforced frame construction and tempered glass protect the entire system against extreme weather events, making it one of the most solid and reliable options currently available on the Polish photovoltaic market. ## Notable figures - Efficiency of 22.8% matches the \*\*N-type 550-600W\*\* median - 228.4 W/m² power density - 3.9 W/m² more than \*\*N-type 550-600W\*\* median (224.5 W/m²), more power per roof area - Temperature coefficient of -0.30%/°C matches the \*\*N-type 550-600W\*\* median - Weight of 27.2 kg (2.3 kg below \*\*N-type 550-600W\*\* median of 29.5 kg) allows easier transport and roof mounting - #2714 for efficiency, #6093 for temperature performance out of 14005 panels ## Questions ### What is the maximum power output of Sunova Tangra M panels and what installations are they suited for? The Tangra M series reaches up to 600 Wp, placing it among the leading high-power-density modules for commercial and residential use. These panels work well on both rooftop and ground-mount installations, especially where maximizing energy yield from limited mounting space is a priority while maintaining strong overall generation performance. ### How does the N-type TOPCon technology in Tangra M differ from common PERC panels? The N-type TOPCon cells used in Tangra M eliminate light-induced degradation (LID), a limitation that affects lifespan in conventional P-type PERC modules. This results in more stable electrical parameters throughout the panel's service life, and a lower temperature coefficient delivers better energy yields on hot days compared to PERC technology. ### What warranty comes with Sunova Tangra M panels? The manufacturer provides a 15-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty. This means the module should still deliver a significant share of its rated power after three decades of operation, making the investment financially predictable and secure. ### Do Sunova Tangra M panels perform well on cloudy days, typical of temperate climates? Yes, the Tangra M series shows strong performance under low-irradiance conditions, resulting in above-average energy yields on overcast days with diffuse light. This is a key advantage in regions with a limited number of fully sunny days per year, where the system still needs to generate efficiently under weaker sunlight. ### Is Sunova a Tier 1 manufacturer, and is investing in Tangra M panels worthwhile? Sunova currently does not hold Tier 1 status under the Bloomberg NEF classification, but the China-based manufacturer offers a technologically advanced Tangra M series with warranty terms close to industry leaders. For investors, the price-to-quality ratio matters most, and the reinforced frame and tempered glass improve resistance to weather stress. ### Are Tangra M panels suitable for roofs with limited mounting space? Yes, this is one of the series' main strengths. Thanks to a high power density of up to 600 Wp per module, Tangra M delivers greater total system capacity from a smaller roof area than standard lower-wattage panels, which is especially valuable for small or irregularly shaped roof sections. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Tangra_M_TS-SWT72580-600_EN_V20241226-4b4ab1ebb010.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -30 W, cooler, +2.0 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +50 W, cooler, +2.0 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -35 W, cooler, +1.8 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +45 W, cooler, +1.8 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +40 W, heavier, +1.6 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | -40 W, lighter, +1.6 pp | | [Sunova RS535~555S8-144GA (535W)](https://comparepv.com/panel/thornova-rs535-555s8-144ga-535w) | 535 W | -55 W, heavier, -2.1 pp | | [Sunova TS-BG72(540)](https://comparepv.com/panel/sunova-ts-bg72-540) | 540 W | -50 W, heavier, -1.9 pp | | [Sunova TS-BW72(545)](https://comparepv.com/panel/sunova-ts-bw72-545) | 545 W | -45 W, -1.7 pp, -5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +60 W, cooler, +2.4 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +55 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/sunova-ts-swt72-590 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
