The use of a **bifacial design** allows for the recovery of additional energy from reflected light, which significantly improves production in ground-mounted installations, on clear ground, or with appropriate racking configurations. The **double-glass construction** is also noteworthy, as it increases resistance to moisture, mechanical stress, and material aging, stabilizing parameters over the long term. The modules utilize **HJT technology**, which is valued for its excellent performance at higher temperatures and low degradation, resulting in predictable energy yields. Another important feature is the **POE sealing**, which supports durability and reduces the risk of degradation in demanding conditions. This is a proposal for investors who expect high production, long-term durability, and a safe LCOE balance. ## Notable figures - Efficiency of 22.5% is 0.5pp below the \*\*HJT 700-750W\*\* median (23.0%) - At 225.3 W/m², this panel generates 4.9 W/m² less per unit area than \*\*HJT 700-750W\*\* median (230.2 W/m²) - At -0.26%/°C, loses 0.02pp more power per degree than \*\*HJT 700-750W\*\* median (-0.24%/°C) - Bifaciality factor of 76% can add 4-11% extra yield with reflective mounting surface - Ranked #4222 out of 14005 panels for efficiency in the database ## Questions ### What is HJT technology and why is it used in the SunKean SKT680~700M12-132D5 series? HJT (Heterojunction Technology) combines monocrystalline silicon with thin amorphous silicon layers. In the SKT680~700M12-132D5 series, this results in a lower temperature coefficient than PERC or TOPCon modules, meaning less power loss on hot days. HJT also delivers an exceptionally low annual degradation rate, which directly supports predictable energy yields over the full service life of the installation. ### What warranty does the SunKean SKT680~700M12-132D5 series come with? The SKT680~700M12-132D5 series includes a 15-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. This means the manufacturer guarantees a defined percentage of rated power will be maintained for three decades — one of the longest warranty packages currently available in the utility-scale PV module market. ### Is the bifacial design of the SunKean SKT680~700M12-132D5 worth it for ground-mount installations? Yes — the bifacial construction of the SKT680~700M12-132D5 is specifically advantageous in ground-mount systems. The rear surface captures light reflected from the ground, and with bright surfaces such as gravel, sand, or grass, this bifacial gain can add several percentage points to overall energy yield. The effect is significantly lower in rooftop applications where there is no reflective surface directly beneath the modules. ### How does the double glass design of the SKT680~700M12-132D5 compare to standard modules with a polymer backsheet? Unlike conventional modules that use a polymer backsheet, the SKT680~700M12-132D5 features glass on both sides of the laminate. This substantially reduces moisture ingress, improves resistance to mechanical loads, and slows material aging of the encapsulant. In practice, it results in more stable long-term electrical performance and a lower risk of moisture-induced degradation such as PID or delamination. ### What is the peak power of the SunKean SKT680~700M12-132D5 and what type of projects is it designed for? The top variant in the series reaches 700 Wp, making these modules a solution aimed primarily at utility-scale solar farms and large commercial installations. The high per-unit power output reduces the total module count on a racking structure, which lowers BoS costs and installation time. This series makes the most sense wherever limited surface area must deliver maximum energy production. ### How do the SunKean SKT680~700M12-132D5 modules perform during hot summer conditions? The HJT technology used in the SKT680~700M12-132D5 series features a lower temperature coefficient than standard PERC cells. This means the modules lose proportionally less power on hot, sunny days compared to lower-cost technologies. In climates where peak summer temperatures can significantly reduce output, this thermal advantage translates into measurable improvements in annual energy yield and a more favorable LCOE. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/6HJT-210mm-680-700W-132cells-Double-Glass-Bifacial-Mono-Hal-af82f6df3690.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | -50 W, lighter, +2.7 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | -20 W, lighter, +2.7 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | -25 W, lighter, +2.5 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Lighter, +2.5 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Lighter, +2.4 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | -30 W, lighter, +2.3 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | -30 W, lighter, +2.3 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | -30 W, lighter, +2.3 pp | | [SunKean SKT680M12-132D5](https://comparepv.com/panel/sunkean-skt680m12-132d5) | 680 W | -20 W, -0.6 pp | | [SunKean SKT685M12-132D5](https://comparepv.com/panel/sunkean-skt685m12-132d5) | 685 W | -15 W, -0.4 pp | | [SunKean SKT690M12-132D5](https://comparepv.com/panel/sunkean-skt690m12-132d5) | 690 W | -10 W, -0.3 pp | | [SunKean SKT695M12-132D5](https://comparepv.com/panel/sunkean-skt695m12-132d5) | 695 W | Very close match | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +105 W, heavier, +2.6 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +100 W, heavier, +2.4 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +95 W, heavier, +2.3 pp | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | +90 W, heavier, +2.1 pp | --- Source: https://comparepv.com/panel/sunkean-skt700m12-132d5 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.
