The modules feature **optimized performance under partial shading**, helping to minimize energy yield losses on roofs with gable parapets, chimneys, or adjacent buildings. The applied architecture, optimized for **better performance at high temperatures**, supports more stable energy production during the summer months, when many standard panels noticeably lose power. In practice, CIPER-TM9C54M stands out with **high resistance to micro-cracks**, which is crucial during transportation, installation, and in areas exposed to wind and snow loads. Additionally, the modules are engineered for long-term reliability thanks to **protection against LID and PID**, translating to more predictable performance over the long term. This is an excellent choice for investors seeking a blend of aesthetics and performance - the series offers **a modern, attractive appearance**, making it suitable for single-family homes and premium buildings, as well as commercial installations, where quality and durability matter. ## Notable figures - Efficiency of 24.5% is 1.8pp above the \*\*TOPCon 500-550W\*\* median (22.7%) - 244.9 W/m² power density - 17.5 W/m² more than \*\*TOPCon 500-550W\*\* median (227.4 W/m²), more power per roof area - At -0.26%/°C (vs median -0.29%/°C), loses ~1% less power in hot conditions - 20.8 kg weight - 6.2 kg lighter than \*\*TOPCon 500-550W\*\* median (27.0 kg), reducing installation effort - #74 for efficiency, #511 for temperature performance out of 14005 panels ## Questions ### How much power does the Talesun CIPRO-TM9C54M module deliver and what drives its high efficiency? The CIPRO-TM9C54M series reaches a maximum output of up to 500 Wp thanks to TOPCon cells, which offer higher conversion efficiency than standard PERC cells. The module's architecture is also optimized for high-temperature operation, so power output drops less noticeably in summer than with many conventional panels. In practice, this translates into higher real-world annual energy yield, especially during periods of strong irradiance. ### What warranty comes with the Talesun CIPRO-TM9C54M panels? The manufacturer backs the CIPRO-TM9C54M series with a 15-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. This means that after 30 years of operation the panel should still deliver the manufacturer-guaranteed percentage of its rated power. Talesun is a Tier 1 manufacturer, which adds confidence that warranty terms will be honored over such a long timeframe. ### Do CIPRO-TM9C54M panels perform well under partial shading, such as from chimneys or dormers? Yes, the CIPRO-TM9C54M series was designed for installations that experience periodic shading - for example from chimneys, dormers, or neighboring buildings. Its partial-shading optimization reduces the drop in energy yield from the entire string when only part of a module is shaded. As a result, the panel performs better on roofs with complex geometry than standard modules without this kind of optimization. ### How does the TOPCon technology in the CIPRO-TM9C54M differ from popular PERC cells? TOPCon (Tunnel Oxide Passivated Contact) is a newer n-type cell technology that uses an additional passivation layer to reduce recombination losses and achieve higher conversion efficiency than standard p-type PERC cells. In practice, this means more power from the same panel area, more stable performance over time, and a smaller efficiency drop at high temperatures. For the investor, this results in higher energy yield from the same roof area. ### Are CIPRO-TM9C54M modules resistant to microcracks and to LID/PID degradation? Yes, panels in this series feature enhanced microcrack resistance, which matters during transport, installation, and in locations exposed to wind and snow loads. The modules are also protected against LID (Light Induced Degradation) and PID (Potential Induced Degradation), limiting uncontrolled power loss in the first years of operation and supporting more predictable, stable energy production throughout the warranty period. ### Is the Talesun CIPRO-TM9C54M a bifacial panel? No, the CIPRO-TM9C54M series is a monofacial panel that generates power only from its front side. Unlike bifacial panels, it doesn't capture light reflected off the ground or roof surface behind it, so its installation doesn't require a special elevated mounting structure or a light-colored surface underneath. This makes it simpler to install and suitable for both sloped roofs and typical ground-mounted arrays. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/470-500-bc-cipro-tm9c54m-full-black-15-20250707-9d52f6f12829.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, heavier, +0.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +0.3 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, heavier | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | -10 W | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, heavier | | [Talesun CIPRO-TN9C54M-470W](https://comparepv.com/panel/talesun-cipro-tn9c54m-470w) | 470 W | -30 W, -1.5 pp | | [Talesun CIPRO-TN9C54M-475W](https://comparepv.com/panel/talesun-cipro-tn9c54m-475w) | 475 W | -25 W, -1.2 pp | | [Talesun CIPRO-TN9C54M-480W](https://comparepv.com/panel/talesun-cipro-tn9c54m-480w) | 480 W | -20 W, -1.2 pp | | [Talesun CIPRO-TM9C54M-485](https://comparepv.com/panel/talesun-cipro-tm9c54m-485) | 485 W | -15 W, -0.7 pp | | [Talesun CIPRO-TN9C54M-490W](https://comparepv.com/panel/talesun-cipro-tn9c54m-490w) | 490 W | -10 W, -0.7 pp | --- Source: https://comparepv.com/panel/talesun-cipro-tm9c54m-500 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.
