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. ## Notable figures - At 22.4% efficiency, this panel is on par with typical \*\*TOPCon 550-600W\*\* modules - At 224.5 W/m² power density, roof space requirements are typical for \*\*TOPCon 550-600W\*\* panels - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 550-600W\*\* median - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof - #4620 for efficiency, #2165 for temperature performance out of 14005 panels ## Questions ### 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. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/5e6e5695ee8afd1712c76dd240d60cd8-e9469b1658a1.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.4 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +2.2 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +50 W, cooler, +1.9 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | -30 W, 16 kg lighter, +1.9 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | -40 W, lighter, +1.9 pp | | [Seraphim SRP-535-BMA-HV](https://comparepv.com/panel/seraphim-srp-535-bma-hv) | 535 W | Hotter, lighter, -1.7 pp | | [Seraphim SRP-540-BMA-BG](https://comparepv.com/panel/seraphim-srp-540-bma-bg) | 540 W | -40 W, hotter, -1.6 pp | | [Seraphim SRP-545-BMA-BG](https://comparepv.com/panel/seraphim-srp-545-bma-bg) | 545 W | -35 W, hotter, -1.3 pp | | [Seraphim SRP-550-BMA-BG](https://comparepv.com/panel/seraphim-srp-550-bma-bg) | 550 W | -30 W, hotter, -1.2 pp | | [Seraphim SRP-555-BMA-BG](https://comparepv.com/panel/seraphim-srp-555-bma-bg) | 555 W | -25 W, hotter, -1.0 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +70 W, lighter, +2.8 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +65 W, lighter, +2.6 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +60 W, lighter, +2.4 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +55 W, lighter, +2.2 pp | --- Source: https://comparepv.com/panel/seraphim-srp-580-bta-bg Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
