The use of **N-type TOPCon technology** helps to minimize losses over time and maintain efficiency even under strong sunlight, resulting in a more consistent energy generation during the summer season. The design based on **half-cut SMBB cells** improves current collection and reduces sensitivity to local shading, making the module better suited for systems with varying orientations or infrastructure elements on the roof. In practice, the SL6N132D solves common problems for PV farms: temperature-related losses, performance degradation over time, and the risk of downtime. This is achieved through **low temperature coefficients** and robust protection of connections and junction boxes, with an IP68 rating. This makes it a good choice for PV farms, carports, and industrial projects where high power density, durability, and efficient installation logistics are priorities. ## 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 -0.24%/°C, hot weather performance is typical for \*\*HJT 700-750W\*\* panels - In the top 30% for efficiency among all HJT panels ## Questions ### What is HJT technology and why is it used in the SunLink SL6N132D series? HJT (Heterojunction Technology) combines a thin amorphous silicon layer with a monocrystalline cell, achieving module efficiency up to 23.2%. This means more energy from the same roof or ground area. HJT also delivers one of the lowest temperature coefficients in the industry (-0.24%/°C), significantly reducing output losses during hot weather — a critical advantage for large-scale PV farms and commercial rooftop installations. ### What warranty does the SunLink SL6N132D come with? The SL6N132D series carries a 15-year product warranty covering manufacturing defects and material faults, plus a 30-year linear power output warranty. The extended power guarantee reflects HJT's low LID (light-induced degradation) characteristics compared to PERC modules, allowing SunLink to commit to predictable energy generation across three decades of operation. ### How does the bifacial design of the SunLink SL6N132D affect real-world energy yield? With 90% bifaciality, the SL6N132D rear side captures up to 90% of the energy relative to the front side. In ground-mounted systems over reflective surfaces such as concrete or gravel, this can increase total yield by several percentage points. Carports and agrivoltaic installations benefit most from the bifacial gain due to strong irradiance reflected from paved or open surfaces beneath the modules. ### Is SunLink a Tier 1 manufacturer, and does it matter when specifying the SL6N132D? SunLink is not currently listed among Tier 1 manufacturers by Bloomberg NEF. For large commercial projects, this may mean lenders require an additional manufacturer risk assessment before approving project financing. It is advisable to confirm eligibility with your bank or project investor before specifying these modules for a utility-scale or commercially financed PV installation. ### How does the SunLink SL6N132D perform during high summer temperatures? HJT technology gives the SL6N132D a temperature coefficient of Pmax of just -0.24%/°C — measurably better than standard PERC modules at -0.35%/°C. For every 10°C rise in module temperature, power loss is only 2.4%, resulting in higher midday output during heat waves and improved annual LCOE for projects in warm climates. This benefit is especially relevant in uncooled ground-mount and industrial rooftop deployments. ### What installations are SunLink SL6N132D 700 Wp panels best suited for, and are they right for residential rooftops? At 700 Wp, the SL6N132D is optimized for large commercial and industrial applications: utility-scale PV farms, multi-bay carports, and rooftops of warehouses or manufacturing facilities. The high power density reduces total module count and simplifies BoS (balance of system), lowering the per-MW installation cost. These modules are too large and heavy for typical single-family residential rooftops — smaller formats up to 450 Wp are better suited for prosumer systems. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/sl6n132d-695-700-03c17a471bdf.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 | Hotter, 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 | Hotter, lighter, +2.5 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Hotter, 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 | | [SunLink SL6N132D-695W](https://comparepv.com/panel/sunlink-sl6n132d-695w) | 695 W | Very close match | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +105 W, hotter, +2.6 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +100 W, hotter, +2.4 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +95 W, hotter, +2.3 pp | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | +90 W, hotter, +2.1 pp | | [Trina Solar TSM-NEG21C.20Q-760](https://comparepv.com/panel/trina-solar-tsm-neg21c-20q-760) | 760 W | +60 W, hotter, +2.0 pp | | [AIKO AIKO-A785-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a785-grh78dw) | 785 W | +85 W, hotter, +1.9 pp | | [Gokin GK-4-78HGBD-780M](https://comparepv.com/panel/gokin-gk-4-78hgbd-780m) | 780 W | +80 W, hotter, +1.8 pp | --- Source: https://comparepv.com/panel/sunlink-sl6n132d-700w 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.
