The key advantage is **high module efficiency** combined with **favorable performance in high temperatures**, which in practice helps minimize losses in yield during summer and on highly heated roofs. The applied solutions also support **optimization for partial shading** - crucial when elements like chimneys, window frames, or seasonal tree shadows appear on the roof. This series is for investors seeking stable performance parameters in real operating conditions: from residential small-scale systems, through small and medium-sized businesses, up to larger rooftop systems on factory halls and ground-mounted structures. What sets it apart from many competitive panels is its **high resistance to micro-cracking** and **good protection against LID and PID degradation**, facilitating high energy production over many years. ## Notable figures - 23.8% module efficiency - 1.3pp better than the \*\*TOPCon 450-500W\*\* median of 22.5% - Power density of 240.1 W/m² packs 14.9 W/m² more into the same footprint vs \*\*TOPCon 450-500W\*\* median (225.2 W/m²) - Temperature coefficient of -0.26%/°C vs median -0.29%/°C means ~1% less power loss at 65°C - At 21.4 kg, this panel is 2.6 kg lighter than \*\*TOPCon 450-500W\*\* median (24.0 kg) - easier handling during installation - In the top 3% for efficiency among all TOPCon panels ## Questions ### What is the maximum power output of the Talesun CIPRO-TN9C54M(H) series panels? The highest-output variants in the CIPRO-TN9C54M(H) series reach up to 500 Wp of maximum power. Thanks to monocrystalline TOPCon cells, the module delivers high efficiency per square meter, allowing more energy from limited roof space and fewer panels needed to reach a target system size. ### What is TOPCon technology, and does it actually matter in Talesun CIPRO panels? TOPCon is an n-type cell technology with an added passivation layer that reduces electron losses and boosts efficiency compared to older PERC cells. In practice, this means higher module power, lower degradation over time, and better performance at high temperatures. In the CIPRO-TN9C54M(H) series, this translates into more stable energy yield throughout the module's lifetime, especially during summer. ### What warranty comes with Talesun CIPRO-TN9C54M(H) panels? The series is covered by a 15-year product warranty and a 30-year power output warranty, guaranteeing a specified percentage of nominal power over the years of operation. This extended coverage goes beyond the previous market standard of 25 years and reflects the manufacturer's confidence in the durability of TOPCon cells and their anti-degradation technology. ### Are Talesun CIPRO panels suitable for a roof with a chimney or dormer causing partial shading? Yes, the CIPRO-TN9C54M(H) series is engineered to reduce losses under partial shading, which matters for roofs with chimneys, dormers, or intermittent tree shade. The module's design helps maintain higher energy production even when part of the panel surface is obstructed, compared to conventional modules without this optimization. ### How do CIPRO-TN9C54M(H) modules perform in summer on a roof that heats up significantly? Thanks to TOPCon technology, panels in this series have a more favorable power temperature coefficient than older PERC modules, meaning less efficiency loss at high panel temperatures. In practice, this results in higher energy yield on hot days and on poorly ventilated roofs, where module temperature can significantly exceed ambient temperature. ### Is Talesun a Tier 1 manufacturer, and are its panels trustworthy? Yes, Talesun holds Tier 1 manufacturer status, indicating financial stability and well-documented, long-term experience in large-scale PV module production. Headquartered in China, the company has supplied panels to European markets for years, and Tier 1 status also makes it easier to secure project financing, as banks and leasing companies often require this confirmation of manufacturer reliability. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/470-500-bc-cipro-tn9c54mh-full-black-15-20250707-708ffba1e58a.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, heavier, +1.2 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +1.0 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, heavier, +0.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +0.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, heavier, +0.7 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +10 W, +0.7 pp | | [Talesun CIPRO-TN9C54M-470W](https://comparepv.com/panel/talesun-cipro-tn9c54m-470w) | 470 W | -20 W, -0.8 pp | | [Talesun CIPRO-TN9C54M-475W](https://comparepv.com/panel/talesun-cipro-tn9c54m-475w) | 475 W | -15 W, -0.5 pp | | [Talesun CIPRO-TN9C54M-480W](https://comparepv.com/panel/talesun-cipro-tn9c54m-480w) | 480 W | -10 W, -0.5 pp | | [Talesun CIPRO-TM9C54M-485](https://comparepv.com/panel/talesun-cipro-tm9c54m-485) | 485 W | Very close match | --- Source: https://comparepv.com/panel/talesun-cipro-tn9c54m-490w 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.
