The applied N-type cell architecture and refined string connection structure help minimize losses and maintain stable performance even under challenging conditions. In practice, you achieve **high efficiency** without needing to expand the mounting surface, simplifying the design of rooftop installations, PV farms, and commercial projects. Worthy of attention is the **optimized performance under partial shading**, which supports energy production in typical scenarios for roof installations with obstructions, rooflights, or HVAC systems. The modules also feature **better performance at high temperatures**, translating to more predictable yields during summer. Additionally, the construction is focused on **resistance to micro-cracking**, enhancing safety during transport and operation. Altogether, this provides **resistance to LID and PID**, crucial for long-term power stability in installations aiming for multi-year returns. ## Notable figures - Efficiency of 24.4% is 2.0pp above the \*\*TOPCon 650-700W\*\* median (22.4%) - Power density of 244.3 W/m² packs 20.6 W/m² more into the same footprint vs \*\*TOPCon 650-700W\*\* median (223.7 W/m²) - Temperature coefficient of -0.26%/°C vs median -0.29%/°C means ~1% less power loss at 65°C - Weight of 28.1 kg (6.5 kg below \*\*TOPCon 650-700W\*\* median of 34.6 kg) allows easier transport and roof mounting - Ranked #99 out of 14005 panels for efficiency in the database ## Questions ### What is the maximum power output of Talesun CIPRO-TN9C72M(H) panels? The CIPRO-TN9C72M(H) series offers power output ranging from 640 to 670 Wp, depending on the selected module variant. With N-type TOPCon cells and a 72-cell layout, the series delivers high power density per area, which is important when designing installations with limited available roof or ground space. ### What warranty comes with Talesun CIPRO-TN9C72M(H) panels? The manufacturer provides a 15-year product warranty and a 30-year linear power output warranty. This means that after 30 years of operation, the module is guaranteed to still deliver a specified percentage of its initial rated power, making this series a solid choice for installations focused on long-term return on investment. ### How does the TOPCon technology in CIPRO panels differ from standard PERC cells? The N-type TOPCon cells used in the CIPRO series have lower recombination losses than PERC cells, resulting in higher efficiency and better performance at elevated temperatures. This technology also improves resistance to LID and PID degradation, ensuring more stable energy production throughout the system's lifetime. ### Do Talesun CIPRO panels perform well in summer heat on hot rooftops? Yes, thanks to the N-type cell architecture, the CIPRO-TN9C72M(H) series has a more favorable power temperature coefficient than modules based on P-type cells. This means a smaller drop in output as module temperature rises, which matters on metal roofs or in regions with high summer irradiance. ### Are CIPRO-TN9C72M(H) panels suitable for roofs with partial shading, such as from chimneys or antennas? Yes, this series is designed with optimized performance under partial shading in mind. The refined cell interconnection reduces energy losses when only part of the panel is shaded, for example by a chimney, antenna, or skylight, improving real-world energy yield in typical urban rooftop conditions. ### Is Talesun a Tier 1 manufacturer, and where are CIPRO panels made? Yes, Talesun is classified as a Tier 1 manufacturer, indicating strong financial stability and extensive experience in large-scale PV module production. The company is headquartered in China. Tier 1 status matters when applying for bank financing for PV installations, as many banks require panels from Tier 1 manufacturers. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/640-670-bc-cipro-tn9c72mh-silver-15-20250701-b6a86d2ed1bb.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | -10 W, lighter, +0.8 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +20 W, +0.8 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +15 W, +0.6 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | -15 W, lighter, +0.6 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +40 W, heavier, +0.6 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +35 W, heavier, +0.5 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +10 W, +0.4 pp | | [Talesun TM3G66M-600](https://comparepv.com/panel/talesun-tm3g66m-600) | 600 W | -60 W, heavier, -2.2 pp | | [Talesun TM3G66M-605](https://comparepv.com/panel/talesun-tm3g66m-605) | 605 W | -55 W, heavier, -2.0 pp | | [Talesun TM9G72M-610W](https://comparepv.com/panel/talesun-tm9g72m-610w) | 610 W | -50 W, heavier, -1.8 pp | | [Talesun TM9G72M-615W](https://comparepv.com/panel/talesun-tm9g72m-615w) | 615 W | -45 W, heavier, -1.6 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +10 W, +0.4 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +10 W, heavier, +0.4 pp | --- Source: https://comparepv.com/panel/talesun-cipro-tn9c72m-h-660 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.
