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 - Efficiency of 23.3% is 0.5pp above the \*\*TOPCon 600-650W\*\* median (22.8%) - At 229.2 W/m² power density, roof space requirements are typical for \*\*TOPCon 600-650W\*\* panels - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 600-650W\*\* median - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces - Ranked #973 out of 14005 panels for efficiency in the database ## 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/937df2b224f8c77953e52110fb37dd24-1f9455855856.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +1.9 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +50 W, lighter, +1.9 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +45 W, lighter, +1.7 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +1.7 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +40 W, lighter, +1.5 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +40 W, lighter, +1.5 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, lighter, +1.5 pp | | [Seraphim SRP-605-BTC-BG](https://comparepv.com/panel/seraphim-srp-605-btc-bg) | 605 W | -25 W, -0.9 pp | | [Seraphim SRP-610-BTC-BG](https://comparepv.com/panel/seraphim-srp-610-btc-bg) | 610 W | -20 W, -0.7 pp | | [Seraphim SRP-615-BTC-BG](https://comparepv.com/panel/seraphim-srp-615-btc-bg) | 615 W | -15 W, -0.6 pp | | [Seraphim SRP-620-BTC-BG](https://comparepv.com/panel/seraphim-srp-620-btc-bg) | 620 W | -10 W, -0.4 pp | | [Seraphim SRP-625-BTC-BG](https://comparepv.com/panel/seraphim-srp-625-btc-bg) | 625 W | Very close match | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +70 W, cooler, +1.7 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +65 W, cooler, +1.6 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +40 W, cooler, +1.5 pp | --- Source: https://comparepv.com/panel/seraphim-srp-630-btc-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.
