Even the lowest variant at 22.7% clearly exceeds Huasun's own portfolio average (~22.1%), confirming consistent above-average performance across all six variants. - **Ultra-low HJT degradation – ≥90.3% after 30 years** - HJT technology guarantees ≤1% first-year degradation and ≤0.3%/year in years 2–30, ensuring ≥90.3% of nameplate power after three decades. Comparable Tier-1 TOPCon modules (e.g., Jinko Tiger Neo) typically guarantee ~87.4% after 30 years — Huasun's advantage of ~2.9 percentage points translates into measurably lower LCOE at utility scale. - **Temperature coefficient of –0.24%/°C** - HJT delivers a power temperature coefficient of –0.24%/°C — substantially better than standard TOPCon (~–0.30 to –0.35%/°C) and PERC (~–0.35%/°C). At a typical cell operating temperature of 55°C, the module loses ~8.4% instead of ~10.5–12.3%, meaningfully increasing summer yield in passively cooled rooftop and ground-mount installations. - **Bifaciality >95% — best in class** - Bifaciality exceeding 95% delivers near-symmetric rear-side output — far above typical TOPCon bifacial modules at 70–85%. On bright white EPDM membranes or light-colored gravel, the rear-side contribution can reach 10–15% above an equivalent monofacial module, directly boosting specific energy yield (kWh/kWp) in ground-mount and flat-roof applications. - **Superior low-light performance** - The amorphous silicon interlayer in the HJT heterojunction structure enhances photon absorption under diffuse and low-irradiance conditions — a critical advantage in Central European climates with frequent overcast days. A real-world 2.65 GW Huasun HJT plant in Yunnan, China exceeded its designed annual output by 2.85% in 2024, demonstrating measurable above-STC generation under sub-optimal irradiance conditions. ## Cons - **Young manufacturer — founded 2020** - Huasun Energy was founded in 2020, giving it only ~5 years of operational history compared to Jinko Solar (2006), Trina Solar (1997), and LONGi (2000). Despite holding BNEF Tier-1 bankability status, the absence of a multi-decade financial track record increases uncertainty when assessing the credibility of a 30-year linear power warranty versus manufacturers with at least 15 years of market history. - **HJT price premium over TOPCon** - HJT modules typically carry a 10–20% cost premium over TOPCon modules of comparable wattage. Direct peer comparables in this series (HY Solar N-Type TOPCon 730 Wp, PolyCrown Mono132 730 Wp) offer identical peak efficiency of 23.5% at a lower per-Wp purchase price, which may extend the simple payback period by approximately 0.5–1 year in standard residential or small commercial installations where rooftop area is not constrained. ## About this series The Huasun Aurora Pro RS705~730S9-132GANT series are bidirectional glass-glass modules designed for high energy production even under less-than-ideal conditions. The use of **N-type cells** helps minimize typical power losses over time, while the **bifacial design** allows for a real increase in energy yield from reflected light from the ground - particularly on bright roofs, membranes, and ground-mounted structures. In practice, this means greater production from the same area and better cost-effectiveness in projects where every square meter counts. These modules are characterized by **excellent performance in low light**, which will be appreciated by investors in Poland, given the frequent cloud cover and seasonal variations in sunlight. A key advantage is also **high PID resistance**, which makes it easier to maintain stable operation of the installation for years. This solution is particularly suitable for PV farms, large industrial roofs, and investments where maximizing energy yield and durability are the top priorities. ## Notable figures - Efficiency of 23.3% matches the \*\*TOPCon 700-750W\*\* median - At 233.4 W/m² power density, this panel generates 3.2 W/m² more per unit area than \*\*TOPCon 700-750W\*\* median (230.2 W/m²) - At -0.31%/°C, loses 0.02pp more power per degree than \*\*TOPCon 700-750W\*\* median (-0.29%/°C) - #943 for efficiency, #8005 for temperature performance out of 14005 panels ## Questions ### What warranty comes with the Huasun Aurora Pro RS705~730S9-132GANT series? The manufacturer provides a 15-year product warranty and a 30-year linear power output warranty. After 30 years the module is guaranteed to retain a specified percentage of its nominal power rating. The extended power warranty is a decisive factor when calculating LCOE and return on investment for utility-scale PV farms and large commercial installations. ### What is TOPCon technology used in the Aurora Pro series and is the premium worth it? TOPCon (Tunnel Oxide Passivated Contact) is a next-generation N-type cell technology that delivers higher conversion efficiency and a lower annual degradation rate than standard PERC cells. The Aurora Pro RS705~730S9-132GANT series reaches module efficiency of up to approximately 23.5%, meaning more energy output from the same footprint. For projects where every square meter counts, the difference in annual yield is tangible. ### Do the bifacial Aurora Pro RS730 panels actually generate more energy, and when does bifacial make sense? Yes, the bifacial glass-glass design allows the rear side of the module to capture light reflected from the surface below, potentially boosting energy yield by several to over ten percent. The gain is greatest in ground-mount systems with a light-colored surface such as gravel, concrete, or a white roofing membrane. On dark pitched rooftops the bifacial contribution is significantly lower and should be factored into the pre-purchase analysis. ### How do the Huasun Aurora Pro 730W panels perform under the cloudy conditions typical in Poland? N-type TOPCon cells demonstrate better low-irradiance performance compared to PERC technology. In Poland's climate, where partially or fully overcast days are frequent throughout the year, this translates into a higher total annual energy yield. The high PID resistance is an added benefit that keeps the system operating stably for years without costly service interventions. ### What types of installations are the Huasun Aurora Pro RS705~730S9-132GANT panels best suited for? The series is designed primarily for utility-scale PV farms and large industrial or warehouse rooftops where maximizing energy output per square meter is the priority. With up to 730 Wp per module, fewer panels are needed, reducing BoS costs and cabling runs. The bifacial glass-glass construction is particularly well suited to ground-mount systems with a reflective surface or flat roofs with white membrane. ### What is the difference between the 705W and 730W variants within the Aurora Pro RS705~730S9-132GANT series? The RS705~730S9-132GANT series covers power classes from 705 to 730 Wp. The only difference between variants is the nominal power rating, which reflects the manufacturer's cell sorting at the production stage. Physical dimensions, cell count (132 cells), and mechanical specifications are identical across the entire range. The specific power class available in a given delivery lot depends on stock availability and project requirements. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/s9-132gant-705-730w-2384x1303x35-eb103ef415c3.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | Cooler, lighter, +1.9 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | -50 W, lighter, +1.7 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Cooler, lighter, +1.7 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Cooler, lighter, +1.6 pp | | [AIKO AIKO-A690-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a690-mae78dw) | 690 W | -35 W, cooler, +1.4 pp | | [AIKO AIKO-A685-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a685-mae78dw) | 685 W | -40 W, cooler, +1.2 pp | | [Trina Solar TSM-NEG21C.20Q-760](https://comparepv.com/panel/trina-solar-tsm-neg21c-20q-760) | 760 W | +35 W, cooler, +1.2 pp | | [AIKO AIKO-A680-MAH78Dw](https://comparepv.com/panel/aiko-aiko-a680-mah78dw) | 680 W | -45 W, cooler, +1.0 pp | | [Huasun HSN-210-B132DSU700](https://comparepv.com/panel/huasun-hsn-210-b132dsu700) | 700 W | -25 W, cooler, -0.8 pp | | [Huasun HSN-210-B132DS705](https://comparepv.com/panel/huasun-hsn-210-b132ds705) | 705 W | -20 W, cooler, -0.6 pp | | [Huasun HSN-210-B132DS710](https://comparepv.com/panel/huasun-hsn-210-b132ds710) | 710 W | -15 W, cooler, -0.4 pp | | [Huasun HSN-210-B132DS715](https://comparepv.com/panel/huasun-hsn-210-b132ds715) | 715 W | -10 W, cooler, -0.3 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +80 W, cooler, +1.8 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +75 W, cooler, +1.6 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +70 W, cooler, +1.5 pp | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | +65 W, cooler, +1.3 pp | --- Source: https://comparepv.com/panel/huasun-rs725s9-132gant Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
