What sets them apart is their **back-contact (BC) architecture**, which eliminates typical front busbars - allowing the panel to utilize light more effectively and offering an exceptionally aesthetic appearance on rooftops. In practice, this translates to **enhanced performance under partial shading**, highly valued in installations near chimneys, window openings, or trees. The CIPRO-TM9C72M also emphasizes stability in challenging conditions: **superior resistance to micro-cracks** helps maintain performance under mechanical stress and temperature fluctuations, while **high resistance to LID and PID** limits performance degradation over the long term. This makes it an excellent choice for demanding residential, commercial, and projects where both maximum yield and a sleek, cohesive module aesthetic are important. ## Notable figures - 23.9% module efficiency - 1.1pp better than the \*\*N-type 600-650W\*\* median of 22.8% - Power density of 238.8 W/m² packs 11.1 W/m² more into the same footprint vs \*\*N-type 600-650W\*\* median (227.7 W/m²) - At -0.26%/°C (vs median -0.29%/°C), loses ~1% less power in hot conditions - At 33.5 kg, weight matches the \*\*N-type 600-650W\*\* median - In the top 3% for efficiency among all N-type panels ## Questions ### What is back contact (BC) technology in the Talesun CIPRO-TM9C72M panels and how does it differ from standard modules? In back contact technology, all electrical connections of the cell are moved to the rear side of the module, so the front surface has no visible busbars. This lets more sunlight reach the active cell area directly, increasing energy yield per unit of roof space. Another effect is a uniform, black front surface with no visible metallization traces, which many homeowners find more visually appealing. ### Do the CIPRO-TM9C72M panels perform better under partial shading, e.g. from a chimney or antenna? Yes, the back contact design combined with N-type cells means the module loses less power when part of the panel is shaded by a chimney, dormer, or nearby tree. Current flow is routed differently than in conventional front-busbar cells, so the drop in output under partial shading is milder. This is a meaningful advantage on complex, obstruction-heavy roof layouts. ### What warranty comes with the Talesun CIPRO-TM9C72M panels? The manufacturer provides a 15-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. This means the panel should maintain a gradually declining but guaranteed performance level over three decades, following the degradation curve stated by the manufacturer. These terms are typical of the premium N-type segment and place the CIPRO-TM9C72M series among the leading offers on the market. ### Is the Talesun CIPRO-TM9C72M a bifacial panel? No, the CIPRO-TM9C72M series is a monofacial module, generating power only from the front side. This is a deliberate design choice for this product line: the focus is on maximizing yield from a single, active side through back contact architecture, rather than adding rear-side gain, which mainly benefits flat-roof or ground-mount installations with a reflective surface below the array. ### How does the CIPRO-TM9C72M series handle microcracks and LID/PID degradation? The series is engineered with improved resistance to microcracks, helping it maintain performance under mechanical loads such as wind or snow, as well as temperature swings on the roof. High resistance to LID (light-induced degradation) and PID (potential-induced degradation) limits unwanted power loss both in the early years of operation and over the long term, resulting in more stable energy yield throughout the warranty period. ### What is the maximum output power in the CIPRO-TM9C72M series and what installations is it suited for? The most powerful variant in the series reaches up to 665 Wp, allowing a high installed capacity with a relatively small number of modules. Thanks to its high yield per unit of roof area and clean, busbar-free front appearance, the series works well both for residential installations on space-constrained roofs and for commercial projects where maximum power density per square meter of roof matters. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/635-665-bc-cipro-tm9c72m-silver-15-20250707-987fd8190834.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Lighter, +1.3 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +35 W, lighter, +1.3 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +30 W, lighter, +1.1 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Lighter, +1.1 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +50 W, heavier, +1.0 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +25 W, lighter, +0.9 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +25 W, lighter, +0.9 pp | | [Talesun TM3G66M-600](https://comparepv.com/panel/talesun-tm3g66m-600) | 600 W | -45 W, hotter, -1.7 pp | | [Talesun TM3G66M-605](https://comparepv.com/panel/talesun-tm3g66m-605) | 605 W | -40 W, hotter, -1.5 pp | | [Talesun TM9G72M-610W](https://comparepv.com/panel/talesun-tm9g72m-610w) | 610 W | -35 W, hotter, -1.3 pp | | [Talesun TM9G72M-615W](https://comparepv.com/panel/talesun-tm9g72m-615w) | 615 W | -30 W, hotter, -1.1 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +55 W, heavier, +1.1 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +25 W, lighter, +0.9 pp | --- Source: https://comparepv.com/panel/talesun-cipro-tm9c72m-645w 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.
