Q-SUN Solar QNM210-HS-60 photovoltaic panels are an advanced solution based on 210 mm G12 silicon cells. Thanks to the use of monocrystalline PERC technology and Half-Cell construction, these modules achieve an impressive power range of 590-610W, making them an ideal choice for large commercial projects and solar farms. The use of larger wafers allows for a significant reduction in BOS system costs, as they generate more energy from a single panel, limiting the number of required mounting structures and cabling. The innovative division of cells in half effectively minimizes internal losses and improves efficiency in partial shading conditions, which directly translates into a more stable annual energy yield. This series stands out from the competition with an excellent balance between high efficiency and mechanical durability, offering a low risk of micro-cracks and better resistance to atmospheric loads. This solves the problem of limited roof space in industrial facilities, delivering maximum power where every dollar of investment saved counts. By choosing these modules, investors gain the certainty of a high power fill factor, which is key to optimizing return on capital in the utility-scale sector. These panels are the foundation of modern installations that focus on durability and long-term profit maximization.

What owners get
High efficiency up to 21.55%

The module reaches up to 21.55% efficiency thanks to PERC technology and half-cut cell design on 210mm G12 wafers, matching Techwise Solar's Summit Series (610W/21.55%) and approaching GCL-M12/60GDF (610W/21.6%).

High unit power output of 590-610W

Larger G12 wafers allow up to 610W per module, reducing the number of mounting structures, connectors, and cable length needed, which lowers BoS costs on large-scale installations.

Half-cut design reduces microcracking

Splitting cells in half lowers mechanical stress and partial-shading losses; per the manufacturer's data, the module withstands wind loads up to 2400 Pa and snow loads up to 5400 Pa, confirming solid mechanical durability.

Long 25-year linear power warranty

The manufacturer offers a 25-year linear power warranty plus a 12-year product warranty, which is the industry standard for PERC modules in this class and supports predictable long-term energy yield.

Trade-offs
Series discontinued

The QNM210-HS-60 series has been discontinued, meaning limited availability of replacement units, harder-to-fulfill warranty service, and supply continuity risks when expanding existing installations.

Manufacturer not on BNEF Tier 1 list

Q-SUN Solar (founded 2014, China) does not appear on the BNEF Tier 1 list, which can complicate bank financing for large commercial projects compared to Tier-1 manufacturers, since bankability is a key criterion for institutional investors.

PERC technology lags behind newer TOPCon

Peer comparable Renewsys DESERV Extreme (TOPCon, bifacial) reaches 23.64% efficiency at the same 610W max power - about 2.1pp higher than the QNM210-HS-60, indicating a technological edge for newer N-type cells over legacy PERC.

No bifacial technology

The module is monofacial, while some competing products in this power segment (e.g., Renewsys DESERV Extreme) offer bifacial dual-glass technology, generating additional yield from the rear side of the panel.

Common questions

6 answered
Is the Q-SUN Solar QNM210-HS-60 series still available for purchase?
The QNM210-HS-60 series has been officially discontinued, meaning Q-SUN Solar has ended its production. It should not be used as the basis for system expansion plans. Individual units may still be available from distributors' warehouse stock, but supply will continue to diminish. Always check current inventory levels with your supplier before committing to this module for a new project.
What warranty does the Q-SUN Solar QNM210-HS-60 module carry?
The QNM210-HS-60 modules come with a 12-year product warranty covering material and workmanship defects, and a 25-year linear power output warranty. Over 25 years, the manufacturer guarantees that power degradation will not exceed defined thresholds, protecting long-term ROI. Note that given the discontinued status, warranty claim enforcement may become more difficult in the long run.
How does the PERC half-cut cell technology in the QNM210-HS-60 series affect performance under partial shading?
The half-cut cell design splits each PERC cell into two halves, reducing internal resistance and lowering the current flowing through the module. This minimizes resistive losses and heat buildup. Under partial shading conditions — such as a chimney or dormer — only a portion of the module loses output instead of the entire string, resulting in more stable annual energy yield compared to standard full-size cells.
Are the QNM210-HS-60 modules with G12 210 mm cells suitable for large-scale solar farms?
Yes, the QNM210-HS-60 series is designed for commercial and utility-scale PV projects. The G12 210 mm cells enable a peak output of up to 610 W per module, which means fewer panels and mounting structures are required per megawatt. This directly reduces BoS (Balance of System) costs and simplifies construction logistics for large ground-mounted installations.
How does the monofacial design of the QNM210-HS-60 compare to bifacial modules — does it affect energy yield?
The QNM210-HS-60 is a monofacial module, generating power only from its front surface. Bifacial modules additionally harvest light reflected from the ground, which on high-albedo ground-mounted systems can yield a few extra percentage points annually. On typical industrial rooftops or installations with limited ground reflectance, the difference is minimal, and monofacial system costs remain lower.
How many QNM210-HS-60 panels are needed to build a 1 MW solar installation?
At a peak power of 610 W per module, a 1 MW installation requires approximately 1,639 QNM210-HS-60 panels. Using the minimum rated power of 590 W, that number rises to around 1,695 units. The exact count depends on the power bin selected and the manufacturer's stated power tolerance. Always use datasheet specifications for the specific production batch when designing the system.
