Seraphim Sable is a series of modules based on N-type TOPCon cells, designed to achieve high energy yields even under less-than-ideal conditions. Thanks to passivated contacts and a multi-busbar architecture, the panels efficiently "collect" current from the cells and perform better in shaded or low-light conditions - which is a significant advantage in the Polish climate, leading to more stable daily energy production.

In practice, Sable solves a common problem for investors: how to increase yield without adding more modules. This is facilitated by the glass-to-glass bifacial design, which can also utilize reflected light from the ground, while also improving resistance to environmental factors. Another key feature is the focus on low power degradation over time, which makes it easier to plan the long-term profitability of the installation.

It is a good choice for residential and commercial installations, as well as ground-mounted projects - anywhere where high production, durability, and predictability are important.

Common questions

6 answered
What warranty does the Seraphim Sable series come with?
The Sable series includes a 15-year product warranty covering defects in materials and workmanship, plus a 30-year power output warranty. After 30 years, Seraphim guarantees at least 84.95% of the rated power. Thanks to TOPCon technology, annual degradation sits at approximately 0.4%, making long-term yield forecasting straightforward for system owners and investors.
What is TOPCon technology and why choose Seraphim Sable over older PERC panels?
TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell design where a thin silicon oxide layer reduces carrier recombination losses. Sable panels deliver higher conversion efficiency than standard PERC cells and a lower temperature coefficient of around -0.29%/°C, meaning smaller power losses on hot days. LID-related initial degradation is below 1%, stabilizing at roughly 0.4% per year thereafter.
Do Seraphim Sable panels perform well in overcast conditions and low irradiance, typical of Northern European climates?
Yes. The multi-busbar architecture shortens current-flow paths between cells and reduces resistive losses at low irradiance. N-type TOPCon cells also show high sensitivity to diffuse light. This translates into measurably better energy yield during cloudy mornings and afternoons, which account for a significant share of production hours in Central and Northern Europe.
What is the maximum power output of the Seraphim Sable module, and will a 720 Wp panel fit on a typical residential roof?
The top variant of the Sable series reaches 720 Wp using 210 mm cells with module efficiency exceeding 23%. This is a large-format panel primarily suited for ground-mount and commercial rooftop installations. For residential projects, Seraphim offers smaller variants within the same Sable series compatible with standard racking systems — confirm the available model with your installer.
Is Seraphim a reliable manufacturer? Where are they based and are they Tier 1?
Seraphim Solar is a Chinese PV manufacturer headquartered in Nantong, operating since 2011 and holding Tier 1 status as recognized by independent rating agencies including BNEF. Tier 1 classification indicates bank-financeable track record and consistent manufacturing capacity, which significantly lowers long-term warranty risk for the system owner.
What temperature range can Seraphim Sable panels handle, and do they work well in winter?
Sable panels are certified for an operating temperature range of -40°C to +85°C, so cold winters pose no risk whatsoever. In fact, N-type TOPCon cells have a lower temperature coefficient than PERC technology, meaning cold but sunny winter days can be especially productive — low ambient temperature reduces thermal losses and boosts output relative to rated STC conditions.
