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.

What owners get
Up to 23.03% efficiency - segment leader

The top-power variant (595 W) reaches 23.03% module efficiency, matching Solarspace Lumina II and Ulica Solar TOPCon 580-595 W. 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.

Trade-offs
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 the Aurora Pro RS570~595S8-144GANT (S8-144GANT) series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

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.
