Thanks to the use of advanced **Half-Cut cell technology** based on large silicon wafers, these modules are characterized by significantly lower energy losses and higher resistance to the negative effects of partial shading. A key differentiator of this series is the **use of Multi-Busbar (MBB) technology**, which not only improves current flow but also minimizes the risk of micro-cracks, directly translating into the longevity of the installation. Designers focused on eliminating the phenomenon of light-induced degradation through **precise gallium doping of silicon**, which guarantees stable operation and maintains high efficiency over many years of use. These models are an ideal solution for large commercial projects and solar farms where a low LCOE is key. By choosing the HYPRO TH3G66M series, you gain investment certainty based on **high power density**, which outperforms standard market solutions in terms of efficiency in difficult weather conditions. This is a solid foundation for systems requiring uncompromising reliability and a fast return on investment. ## Notable figures - Efficiency of 22.2% matches the \*\*HJT 600-650W\*\* median - 222.1 W/m² power density is 3.7 W/m² below \*\*HJT 600-650W\*\* median (225.8 W/m²) - requires larger installation area - At -0.24%/°C, hot weather performance is typical for \*\*HJT 600-650W\*\* panels - At 32.6 kg, weight matches the \*\*HJT 600-650W\*\* median - Bifacial design (90% factor) captures reflected light - adds 4-14% yield on ground-mount or white roof ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/600-635-HYPRO_TH3G66M_0BB_Silver_20250311_EN-909fdb28ea24.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +50 W, lighter, +3.0 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +45 W, lighter, +2.8 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -40 W, lighter, +2.6 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +40 W, lighter, +2.6 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -45 W, lighter, +2.4 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +35 W, lighter, +2.4 pp | | [Talesun TM3G66M-605](https://comparepv.com/panel/talesun-tm3g66m-605) | 605 W | Hotter, heavier | | [Talesun TM9G72M-610W](https://comparepv.com/panel/talesun-tm9g72m-610w) | 610 W | Hotter, heavier, +0.4 pp | | [Talesun TM9G72M-615W](https://comparepv.com/panel/talesun-tm9g72m-615w) | 615 W | +15 W, hotter, +0.6 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +80 W, lighter, +3.0 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +75 W, lighter, +2.8 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +100 W, hotter, +2.8 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +95 W, hotter, +2.7 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +70 W, lighter, +2.6 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +70 W, lighter, +2.6 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +70 W, hotter, +2.6 pp | --- Source: https://comparepv.com/panel/talesun-talesun-th3g66m-600 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
