It outperforms the Sunova TS-BW78 peer (max 21.3%) by roughly 1.7 pp, delivering measurably higher specific yield per m² of roof or ground area. - **N-type TOPCon: lower LID and better thermal performance** - N-type TOPCon cells exhibit LID below 1% versus the typical 2-3% for P-type PERC. The power temperature coefficient for TOPCon is typically around -0.30%/°C versus -0.35-0.40%/°C for PERC, translating into measurably higher daily yield during hot summer conditions. - **Bifacial glass-glass: higher yield and durability** - The bifacial dual-glass construction captures 10-25% additional energy from the rear side (depending on ground albedo). Eliminating the backsheet removes the risk of delamination and bubbling over time, while the sealed glass-glass encapsulation provides superior moisture and UV resistance - critical for ground-mount and flat-roof installations. - **30-year linear power warranty + PID protection** - Huasun backs the module with a 30-year linear power warranty and a separate 15-year product warranty. Coverage explicitly includes Potential Induced Degradation (PID) and Light-Induced Degradation (LID) - aspects frequently excluded by competitors in standard terms. The 30-year power guarantee horizon directly supports LCOE analysis for bank-financed utility-scale projects. - **BNEF Tier 1 bankable manufacturer** - Huasun Energy achieved BNEF Tier 1 Bankable PV Module Manufacturer status in Q1 2025. This classification, recognized by lenders for PV project financing, confirms the manufacturer meets criteria for financial stability and operational capability - directly relevant for commercial and utility-scale project finance. ## Cons - **Short operating history of the manufacturer** - Huasun Energy was founded in July 2020, giving it only ~5 years of market history against a 30-year power warranty obligation. By comparison, Trina Solar was established in 1997 and JA Solar in 2005. Despite BNEF Tier 1 status, the absence of a long-term field performance track record and the company's shorter financial runway represent a risk factor when assessing real warranty enforceability in the 2045-2055 timeframe. ## About this series The Huasun Aurora Pro RS570~595S8-144GANT (S8-144GANT) series is designed to maximize energy yield in installations where every square meter counts. These are **bifacial** modules with a **glass-glass** construction that can effectively utilize reflected light from the ground - this makes it easier to increase production without expanding the system. The use of **n-type TOPCon** technology helps to minimize losses due to light-induced degradation, which translates into more stable operation over the long term. In practice, this means better predictability of yields and a lower risk of disappointment after a few seasons. Aurora Pro also performs well in low-light conditions - such as cloudy, foggy, or winter weather, which is particularly important in Poland. This series is recommended for PV farms, commercial installations, and demanding rooftop and ground-mounted projects where **high durability** and **PID resistance** are priorities. This makes it easier to compete on cost, improving LCOE without compromising quality. ## Notable figures - Efficiency of 22.1% matches the \*\*TOPCon 550-600W\*\* median - At 220.7 W/m², this panel generates 3.8 W/m² less per unit area than \*\*TOPCon 550-600W\*\* median (224.4 W/m²) - At -0.31%/°C, loses 0.02pp more power per degree than \*\*TOPCon 550-600W\*\* median (-0.29%/°C) - At 32.5 kg, this panel is 1.3 kg heavier than the \*\*TOPCon 550-600W\*\* median (31.2 kg) - more demanding for installation crews - Ranked #6199 out of 14129 panels for efficiency in the database ## Questions ### What is the peak power output and cell efficiency of the Huasun Aurora Pro RS570~595 S8-144GANT? The top module in the series delivers 595 Wp under standard test conditions (STC). The full series spans 570-595 W, giving system designers flexibility when sizing a project. With n-type TOPCon cells and a bifacial glass-glass structure, module efficiency exceeds 22%, placing it among the top-performing 144-cell modules currently on the market. ### What product and power warranties does the Huasun Aurora Pro S8-144GANT series carry? Huasun provides a 15-year product warranty covering materials and workmanship, plus a 30-year linear power warranty. Power output degrades in a controlled, gradual manner over three decades of operation. The extended power warranty directly supports a lower LCOE calculation - the cost of generating 1 kWh spread over the system's entire lifetime - which is critical when evaluating the return on investment. ### What does glass-glass construction mean and is the heavier Aurora Pro module practical for pitched rooftop installations? Glass-glass construction replaces the traditional polymer back sheet with a second pane of tempered glass. This delivers superior resistance to moisture ingress, UV degradation, and thermal cycling - important advantages in variable climates. However, glass-glass modules weigh more than conventional framed panels, so a structural assessment of roof load capacity is recommended before installation on pitched rooftops. ### How does n-type TOPCon technology in the Aurora Pro differ from standard PERC, and why does it matter for long-term system performance? TOPCon (Tunnel Oxide Passivated Contact) uses an n-type silicon base with a thin tunnel oxide passivation layer that reduces charge carrier recombination losses. The key practical advantage over p-type PERC is near-zero LID (Light Induced Degradation) - the power drop observed in PERC modules during the first weeks of outdoor operation. A lower annual degradation rate means significantly more cumulative energy yield over a 30-year system lifetime and more predictable performance modeling. ### Do the bifacial Aurora Pro modules actually generate more energy, and under what conditions is the rear-side gain most significant? Yes, when the installation is optimized for rear-side irradiance. Bifacial modules harvest both direct front-side irradiance and albedo (reflected) light through the rear glass pane. On ground-mounted systems with light-colored gravel, concrete, or snow cover, rear-side gain typically adds 5-15% to total energy yield. On dark rooftops with minimal reflective surfaces, the bifacial premium is minimal, though the glass-glass encapsulation still provides durability benefits. ### How do Huasun Aurora Pro S8-144GANT modules perform in low-irradiance conditions such as overcast skies or winter months? N-type TOPCon cells deliver proportionally better output under diffuse and low-intensity irradiance compared to p-type PERC cells, making the Aurora Pro series well-suited for climates with frequent cloud cover or short winter days. This improved low-light performance translates into a higher annual net energy yield and reduces the impact of seasonal variation on the system's energy balance - a meaningful advantage in Central and Northern European markets. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/s8-144gant-570-595w-2278x1134x30-076a2612fec4.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.7 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +2.5 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, 16 kg lighter, +2.3 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | Cooler, lighter, +2.3 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | Cooler, lighter, +2.3 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | Cooler, lighter, +2.2 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | Cooler, lighter, +2.1 pp | | [Huasun RS575S8-144GANT](https://comparepv.com/panel/huasun-rs575s8-144gant) | 575 W | Very close match | | [Huasun RS580S8-144GANT](https://comparepv.com/panel/huasun-rs580s8-144gant) | 580 W | +10 W, +0.4 pp | | [Huasun RS585S8-144GANT](https://comparepv.com/panel/huasun-rs585s8-144gant) | 585 W | +15 W, +0.6 pp | | [Huasun RS590S8-144GANT](https://comparepv.com/panel/huasun-rs590s8-144gant) | 590 W | +20 W, +0.8 pp | | [Huasun RS595S8-144ANT](https://comparepv.com/panel/huasun-rs595s8-144ant) | 595 W | +25 W, +1.0 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +80 W, lighter, +3.1 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +75 W, lighter, +2.9 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +70 W, lighter, +2.7 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +65 W, lighter, +2.5 pp | --- Source: https://comparepv.com/panel/huasun-rs570s8-144gant Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
