A key advantage of this series is **low power degradation over time**, ensuring that the installation continues to produce high levels of energy for a longer period and improves the overall return on investment, especially for self-consumption and selling excess energy. The TN5-44H performs well in hot weather, which helps to minimize energy losses during peak summer demand. This translates to more predictable performance and greater resistance to weather conditions compared to many standard PERC systems. Furthermore, the modules are designed for installations with enhanced safety requirements, thanks to a **robust IP68-rated junction box** and a solid construction. This series is recommended for single-family homes, small businesses, and projects where **long-term reliability** and trouble-free operation are paramount. ## Notable figures - At 19.5% efficiency, this panel is 3.5pp above typical \*\*TOPCon 0-400W\*\* modules (median: 16.0%) - Power density of 194.6 W/m² packs 34.8 W/m² more into the same footprint vs \*\*TOPCon 0-400W\*\* median (159.8 W/m²) - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 0-400W\*\* median - Weight of 21.0 kg (2.5 kg below \*\*TOPCon 0-400W\*\* median of 23.5 kg) allows easier transport and roof mounting - #12702 for efficiency, #6093 for temperature performance out of 14005 panels ## Questions ### How does TOPCon technology in TN Solar TN5-54H panels differ from standard PERC panels? TOPCon (Tunnel Oxide Passivated Contact) uses N-type monocrystalline cells with an additional passivation layer that reduces electron recombination losses at the metal-silicon contact. As a result, TN5-54H modules achieve higher efficiency and lower power degradation over time compared to standard PERC panels based on P-type cells. In practice, this means higher energy yield throughout the system's lifetime. ### What warranty comes with TN Solar TN5-54H panels? TN5-54H panels come with a 25-year product warranty and a 30-year power output warranty. This means the manufacturer covers not only manufacturing defects but also guarantees a defined performance level over three decades, which is important when calculating the return on investment for a solar installation. ### How much power does a single TN5-54H panel produce? Modules in the TN5-54H series reach a maximum power output of 390 Wp. Thanks to TOPCon cell technology, the panel maintains high efficiency despite its compact size, allowing more power to be fitted into limited roof space, particularly useful for smaller residential installations. ### Do TN5-54H panels perform well in summer heat and high temperatures? Yes, thanks to TOPCon technology and N-type cells, TN5-54H panels have a more favorable temperature coefficient than typical PERC modules. This results in a smaller drop in energy yield on hot days, when panel surface temperatures can exceed 60°C. In practice, this translates into more stable power production during summer months, when energy demand is usually at its peak. ### Are TN5-54H panels bifacial, generating power from both sides? No, the TN5-54H series consists of monofacial modules rather than bifacial ones. This means energy generation occurs only from the front surface of the panel. This design works well for standard rooftop installations, where the rear side of the module typically doesn't receive enough reflected light to make bifacial technology cost-effective. ### Is the junction box on TN5-54H panels resistant to moisture and rain? Yes, TN5-54H modules feature an IP68-rated junction box, the highest protection class available for this type of component. This provides full protection against dust and resistance to prolonged water immersion, ensuring safe electrical connections even in harsh weather conditions, heavy rainfall, or high humidity. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/tn-370-390w-red-solar-module-f8f35fa61d01.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | -50 W, lighter, +3.7 pp | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | -50 W, lighter, +3.7 pp | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | -40 W, lighter, +3.5 pp | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | -20 W, lighter, +3.5 pp | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | Lighter, +3.5 pp | | [Gamko New Energy GKA210M400W (1/2\*4\*20)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-2-4-20) | 400 W | +20 W, lighter, +3.5 pp | | [Gamko New Energy GKA210M400W (1/4\*4\*40)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-4-4-40) | 400 W | +20 W, lighter, +3.5 pp | | [Gamko New Energy GKA210M380W (1/2\*4\*19)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19) | 380 W | Lighter, +3.5 pp | | [Maxeon SPR-MAX3-430-R](https://comparepv.com/panel/maxeon-spr-max3-430-r) | 430 W | +50 W, +3.2 pp, +10 yr warranty | | [Maxeon SPR-MAX3-400-COM](https://comparepv.com/panel/maxeon-spr-max3-400-com) | 400 W | Cooler, +3.1 pp, +10 yr warranty | | [TN Solar TN5-54H-370](https://comparepv.com/panel/tn-solar-tn5-54h-370) | 370 W | -10 W, -0.5 pp | | [TN Solar TN5-54H-375](https://comparepv.com/panel/tn-solar-tn5-54h-375) | 375 W | -0.3 pp | | [TN Solar TN5-54H-385](https://comparepv.com/panel/tn-solar-tn5-54h-385) | 385 W | +0.2 pp | | [TN Solar TN5-54H-390](https://comparepv.com/panel/tn-solar-tn5-54h-390) | 390 W | +10 W, +0.5 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +130 W, cooler, +5.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +115 W, cooler, +5.3 pp | --- Source: https://comparepv.com/panel/tn-solar-tn5-54h-380 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
