N-type cells virtually eliminate light-induced degradation (LID/LeTID) common to legacy p-type PERC - critical for utility-scale plants targeting a 25+ year operational life. - **30-year linear power warranty at ≥87.4%** - Manufacturer guarantees at least 87.4% of rated output after 30 years, surpassing the standard 25-year warranty typical of PERC-era products. The extended warranty horizon reduces modeled LCOE and supports project bankability during lender due diligence. - **Low temperature coefficient: -0.310%/°C** - At -0.310%/°C, the Pmax temperature coefficient outperforms standard PERC (-0.350%/°C). At a summer cell temperature of 60°C (35°C above STC), a 630W module loses ~68.4W versus ~77.2W for a comparable PERC module - roughly 9W per module saved during peak summer irradiance hours. - **Bifacial gain in dual-glass configuration** - TOPCon glass-glass bifaciality averages 70-80% (ENF Solar / Runda Solar datasheet). On ground-mounted arrays with an albedo of 0.2-0.4 (light gravel, bare soil, or snow cover), this translates to an additional 5-15% annual energy yield versus a same-wattage monofacial module. ## Cons - **Manufacturer identity vs. BNEF Tier-1 status** - The Aurora Pro RS605~630S8R-132GANT series is listed in the ENF Solar panel directory and on rundapv.com as a product of Runda Solar (Jiangsu Runda PV Co., Ltd.), not Huasun. Runda Solar does not appear on the BNEF Tier 1 PV Module Manufacturers list for Q1 2025 - unlike Huasun, which holds Tier-1 status for its HJT product lines. Projects where EPC agreements or project finance terms require confirmed Tier-1 manufacturer status should verify the manufacturer of record with the distributor prior to purchase. - **Wide power bin spread across variants (Δ25W / 4.1%)** - Six variants span 605-630W with efficiencies ranging from 22.4% to 23.32% (Δ0.92 pp). Without explicitly specifying the power bin in the purchase order, a 1 MWp project (~1,590 modules) may receive lower-bin units (22.4% efficiency), materially reducing actual DC capacity and annual yield versus the financial model assumption. ## About this series The Huasun Aurora Pro RS605~630S8R-132GANT series is designed for installations where maximizing energy yield per square meter and predictable performance over the years are paramount. These are **bidirectional (bifacial) modules** with a dual-glass construction, allowing them to utilize reflected light from the ground - which significantly improves energy production in ground-mounted farms, on bright roofs, and in configurations with high albedo. The use of **n-type cells** reduces the risk of power drops typical of older technologies and supports stable performance over the long term. In practice, Aurora Pro stands out due to its **high PID resistance** and **excellent performance in low-light conditions** - which is important in Polish conditions with frequent cloud cover. An additional advantage is the **long warranty on power output**, which simplifies project financing and LCOE calculation. This makes it a good choice for PV farms, large industrial roofs, and investors who want to increase energy yield without complicating their project. ## Notable figures - At 23.1% efficiency, this panel is on par with typical \*\*TOPCon 600-650W\*\* modules - At 231.4 W/m² power density, this panel generates 3.7 W/m² more per unit area than \*\*TOPCon 600-650W\*\* median (227.7 W/m²) - Temperature coefficient of -0.31%/°C is 0.02pp worse than \*\*TOPCon 600-650W\*\* median (-0.29%/°C) - higher losses in summer heat - At 34.5 kg, this panel is 1.7 kg heavier than the \*\*TOPCon 600-650W\*\* median (32.8 kg) - more demanding for installation crews - #1554 for efficiency, #8069 for temperature performance out of 14129 panels ## Questions ### What is the warranty on Huasun Aurora Pro RS605~630S8R-132GANT panels? The Aurora Pro series comes with a 15-year product warranty and a 30-year linear power output warranty. The manufacturer guarantees the module retains a defined percentage of its nominal power after 30 years. This extended warranty horizon simplifies project financing and LCOE calculations - banks and financial institutions funding utility-scale PV projects treat it as a key bankability indicator. ### How much extra energy does the bifacial Aurora Pro module generate compared to a monofacial panel? Bifacial modules in the Aurora Pro series can generate anywhere from a few percent to 15-20% more energy than a monofacial equivalent, depending on ground albedo. The gain is greatest on farms with light-colored gravel, concrete, or snow cover. The dual-glass construction also seals the rear surface against moisture, increasing module longevity and overall energy yield across the system's entire lifetime. ### What is TOPCon technology used in Aurora Pro and how does it differ from PERC? TOPCon (Tunnel Oxide Passivated Contact) is an n-type cell architecture featuring a thin tunnel oxide layer that reduces charge carrier recombination. In practice, this delivers higher efficiency than standard PERC cells, lower long-term degradation, and better resistance to LID (Light Induced Degradation). As a result, Aurora Pro panels maintain more stable performance parameters throughout the full 30-year operating period. ### Do Huasun Aurora Pro RS605~630S8R-132GANT panels perform well in cloudy climates like Poland? Yes. N-type TOPCon cells are known for strong low-irradiance performance, which is critical in Poland, where a significant portion of annual energy production comes from days with diffuse rather than direct sunlight. The Aurora Pro series also features high PID resistance, preventing rapid parameter degradation under high-humidity conditions typical of Polish winters and spring. ### What types of installations are Huasun Aurora Pro panels rated up to 630 Wp best suited for? With up to 630 Wp and a bifacial dual-glass construction, the Aurora Pro is designed primarily for utility-scale ground-mounted solar farms and large industrial rooftops where the bifacial gain can be fully realized. The 132-cell format also suits solar tracker systems. Due to its large dimensions and weight, it is generally not a first choice for small residential rooftop installations. ### Does the dual-glass construction of Aurora Pro RS605~630S8R-132GANT provide better durability than standard backsheet modules? Yes. The rear glass in a dual-glass module delivers higher mechanical strength and impermeability than a polymer backsheet - it protects cells from moisture, ammonia, and UV radiation. This results in slower degradation and a longer system lifespan, which is especially relevant in demanding ground-mount farm environments where atmospheric exposure is more severe than on rooftops. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/s8r-132gant-605-630w-2382x1134x30-5e29e4d97e0e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +2.1 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +50 W, lighter, +1.9 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +1.9 pp | | [WINAICO WST-675BKX72-A2](https://comparepv.com/panel/winaico-wst-675bkx72-a2) | 675 W | +50 W, cooler, +1.9 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | Cooler, lighter, +1.7 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | Cooler, lighter, +1.7 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, lighter, +1.7 pp | | [Huasun HSN-210R-B88DSN400](https://comparepv.com/panel/huasun-hsn-210r-b88dsn400) | 400 W | -225 W, cooler, -8.3 pp | | [Huasun HSN-210R-B88DSN405](https://comparepv.com/panel/huasun-hsn-210r-b88dsn405) | 405 W | -220 W, cooler, -8.1 pp | | [Huasun HSN-210R-B88DSN410](https://comparepv.com/panel/huasun-hsn-210r-b88dsn410) | 410 W | -215 W, cooler, -7.9 pp | | [Huasun HSN-210R-B132DSU590](https://comparepv.com/panel/huasun-hsn-210r-b132dsu590) | 590 W | -35 W, cooler, -1.3 pp | | [Huasun HSN-210R-B132DSU595](https://comparepv.com/panel/huasun-hsn-210r-b132dsu595) | 595 W | -30 W, cooler, -1.1 pp | | [Huasun HSN-210R-B132DSU600](https://comparepv.com/panel/huasun-hsn-210r-b132dsu600) | 600 W | -25 W, cooler, -0.9 pp | | [Huasun HSN-210R-B132DSU605](https://comparepv.com/panel/huasun-hsn-210r-b132dsu605) | 605 W | -20 W, cooler, -0.7 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +55 W, lighter, +2.1 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +75 W, cooler, +1.9 pp | --- Source: https://comparepv.com/panel/huasun-rs625s8r-132gant 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.
