The Recom Lynx series consists of modules based on N-type TOPCon cells, designed for high efficiency and stable performance over long periods. A key advantage is minimal LID degradation and the absence of LeTID risk, which translates directly into more predictable energy production throughout the entire lifespan of the installation. In practice, this means fewer disappointments after several seasons and a better return on investment - especially in situations where long-term performance is critical.

The Lynx series is available in mono- and bi-facial versions, including a double-sided (glass-glass) construction, which enhances resistance to weather conditions and mechanical loads. Thanks to its bi-facial design, the module can utilize reflected light from the ground, improving efficiency without increasing the surface area. This makes it a good choice for PV farms, commercial and industrial rooftops, and demanding prosumers who require low temperature coefficients and high performance in hot weather. Furthermore, the series is supported by a long warranty, which simplifies cost and risk planning for the project.

What owners get
N-type TOPCon cell technology

N-type TOPCon cells exhibit negligible LID degradation and no LeTID risk, and combined with up to 23.5% efficiency deliver a more predictable and stable energy yield throughout the system's operating life.

30-year linear power warranty

The manufacturer guarantees at least 87.4% of nominal power retained after 30 years, backed by a 30-year product warranty - well above the market-standard 25 years, simplifying long-term project risk and cost planning.

Efficiency on par with segment leaders

The 23.5% peak efficiency matches the best comparable series, such as Huasun Himalaya V-ocean and Phono Solar Monocrystalline132/Helios, which reach the same 23.5% at the same maximum power of 730 Wp.

Wide power range of 440-730 Wp

A 33-variant portfolio spanning 440 to 730 Wp allows the right module to be selected for both C&I rooftops and utility-scale PV farms without switching suppliers.

Glass-glass variant for added durability

The double-glass construction available in the series improves mechanical and weather resistance, reducing the risk of microcracking and laminate degradation over the long term, consistent with the 30-year product warranty.

Trade-offs
No current Tier-1 (bankability) status

Recom achieved BNEF Tier 1 status back in 2019, but according to current data the manufacturer is not presently classified as tier-1 bankable, which can complicate project financing for banks and funds screening suppliers against the current BNEF list.

Base series lacks bifacial gain

The flagship Lynx specification indicates a monofacial module, while a direct competitor at the same power and efficiency (Huasun Himalaya V-ocean, 730 Wp/23.5%) offers a bifacial construction with additional rear-side yield - in ground-mount farm applications this means forgoing a potential energy gain of several percent.

Common questions

6 answered
What warranty does the Recom Lynx series come with and what does it cover?
The Recom Lynx series includes a 30-year product warranty and a 30-year linear power output guarantee. At the end of the warranty period, the module must retain at least 87.4% of its nominal power. For a 730 Wp panel, that means a guaranteed minimum of approximately 637 W after three decades of operation — one of the longer warranty commitments on the market and a meaningful factor when calculating project LCOE.
What is TOPCon technology and why does the Recom Lynx series use it?
TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology that uses a thin tunnel oxide layer to suppress carrier recombination. The result is higher module efficiency and virtually no LID (Light Induced Degradation) or LeTID risk compared to conventional PERC cells. In practice, Recom Lynx panels lose less power in the first seasons of operation and deliver more predictable energy output over their entire service life.
Are Recom Lynx panels a good fit for large-scale solar farms and commercial or industrial rooftops?
Yes. The Lynx series reaches up to 730 Wp per module, placing it squarely in the large-format segment suited for utility-scale PV farms and C&I installations. Higher per-module power reduces the number of panels needed for a given capacity, lowering BoS costs and installation labor. The series is also available in bifacial glass-glass variants that capture reflected irradiance and further improve overall energy yield.
How does the Recom Lynx series handle temperature losses during hot summer days?
The N-type TOPCon cells used in the Lynx series have a lower power temperature coefficient than conventional PERC cells. This means smaller power losses when module temperatures are high — a common condition on sun-exposed rooftops and ground-mounted arrays during summer. For installations in warm climates or on dark roofing materials, this translates into a measurably better annual energy yield compared to older PERC-based modules.
Is Recom a reliable manufacturer and is the Lynx series still available?
Recom Technologies is an Italian-headquartered manufacturer that continues to actively develop the Lynx line — the latest models exceed 720 Wp at efficiencies above 23%. The company is not currently listed on major Tier 1 agency rankings, but the Lynx series remains in active production and is commercially available. When purchasing, it is worth verifying local distributor warranty support as an additional safeguard for your investment.
How does the Recom Lynx series differ from PERC-based modules?
The key distinction is N-type TOPCon cells versus the more common P-type PERC architecture. N-type cells do not exhibit LID or LeTID, which can reduce PERC module output by a few percent within the first months of operation. Lynx modules also achieve higher efficiency for the same footprint, making them a strong choice wherever roof or land area is constrained and maximizing yield per square meter is a priority.
