The panels use a **half-cut** cell structure combined with advanced multi-busbar interconnections, reducing resistive losses and improving mechanical resistance to micro-cracks. Thanks to its **bifacial design**, the module also captures solar radiation from the rear side, generating additional energy from reflected and diffuse light - a solution especially valued by investors installing systems on light-colored surfaces, flat roofs, or ground-mounted solar farms. The series also stands out with a low temperature coefficient, translating into better performance on hot days and more stable output under low-irradiance conditions. Tiger Neo III answers the market's growing demand for high power density panels that reduce the surface area needed to reach a given system capacity, lowering overall **BoS** costs. It is a solid choice for both residential and commercial investors seeking proven, bankable technology backed by a long-term warranty and a low **LCOE**. ## Notable figures - Efficiency of 24.8% is 1.5pp above the \*\*N-type 650-700W\*\* median (23.3%) - At 248.0 W/m² power density, this panel generates 14.8 W/m² more per unit area than \*\*N-type 650-700W\*\* median (233.2 W/m²) - At -0.26%/°C (vs median -0.29%/°C), loses ~1% less power in hot conditions - At 32.5 kg, weight matches the \*\*N-type 650-700W\*\* median - Bifaciality factor of 85% can add 4-13% extra yield with reflective mounting surface ## Questions ### What makes the TOPCon technology in Tiger Neo III different from standard PERC panels? The N-type TOPCon cells used in the Tiger Neo III feature an additional passivation layer that reduces carrier recombination and lowers module degradation over time compared to conventional P-type PERC cells. As a result, the panel maintains higher energy yield throughout its service life, with lower first-year and long-term degradation than older cell technologies. ### What is the maximum power output of the Jinko Tiger Neo III panel, and how many modules are needed for a typical 10 kWp installation? Panels in the Tiger Neo III series reach a maximum power of up to 670 Wp. For a 10 kWp installation, roughly 15 modules from this series are sufficient, fewer than with older 400-450 W panels. The high power density reduces the roof area needed to reach a target installation capacity and lowers BoS costs for the mounting structure. ### What warranty applies to the Tiger Neo III series? Jinko Solar provides a 25-year product warranty and a 30-year power output warranty for the Tiger Neo III series. This means the manufacturer covers not only material and workmanship defects but also guarantees a specified level of energy performance over three decades, making this series one of the more bankable offerings on the market. ### Are Tiger Neo III panels suitable for a pitched roof on a single-family home? Yes, Tiger Neo III modules are a popular choice for residential installations on pitched roofs. The half-cut cell structure and multi-busbar interconnections increase resistance to microcracks that can occur during transport and installation, and the high per-panel power output allows more system capacity to fit on a limited pitched roof area. ### How do Tiger Neo III panels perform on hot days and in low-light conditions? The Tiger Neo III series has a low temperature coefficient of power, so it loses less efficiency during heat waves than older module generations when cell temperature rises above standard test conditions. N-type TOPCon technology also responds better to weak and diffuse light, resulting in more stable energy production on cloudy days and during early morning or evening hours. ### Is Jinko Solar a tier 1 manufacturer, and can it be trusted for a long-term investment? Yes, Jinko Solar is classified as a tier 1 manufacturer, meaning stable financial standing, high production volume, and a long-established global presence. This matters in practice for a 25-30-year warranty, as it increases the likelihood the manufacturer will be able to honor warranty claims throughout the system's service life, which is relevant for both residential and commercial investors. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/JKM650-670N-66QL6-BDV-F4-EU-d99410165a96.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | -20 W, lighter, +0.4 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +10 W, lighter, +0.4 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | Lighter | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | -25 W, lighter | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +30 W, heavier | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +25 W, heavier | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | Lighter | | [Jinko Solar JKM605-630N-66HL4M-BDV-F3-EN (605W column)](https://comparepv.com/panel/jinko-solar-jkm605-630n-66hl4m-bdv-f3-en-605w-column) | 605 W | -65 W, hotter, -2.4 pp | | [Jinko Solar JKM605-630N-66HL4M-BDV-F3-EN (610W column)](https://comparepv.com/panel/jinko-solar-jkm605-630n-66hl4m-bdv-f3-en-610w-column) | 610 W | -60 W, hotter, -2.2 pp | | [Jinko Solar JKM605-630N-66HL4M-BDV-F3-EN (615W column)](https://comparepv.com/panel/jinko-solar-jkm605-630n-66hl4m-bdv-f3-en-615w-column) | 615 W | -55 W, hotter, -2.0 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | Lighter | --- Source: https://comparepv.com/panel/jinko-solar-jkm670n-66ql6-bdv-f4-eu Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
