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 22.9% matches the \*\*TOPCon 550-600W\*\* median - Power density of 229.4 W/m² packs 5.0 W/m² more into the same footprint vs \*\*TOPCon 550-600W\*\* median (224.4 W/m²) - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 550-600W\*\* panels - Weight of 33.8 kg is 2.6 kg above \*\*TOPCon 550-600W\*\* median (31.2 kg) - verify structural support - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof ## 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/5ee279029e6464a21519600fb8625229-666b60c9d66b.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +1.9 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +1.7 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, 17 kg lighter, +1.5 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | Cooler, lighter, +1.5 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | Cooler, lighter, +1.5 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | Cooler, lighter, +1.3 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | Cooler, lighter, +1.3 pp | | [Seraphim SRP-550-BTB-BG](https://comparepv.com/panel/seraphim-srp-550-btb-bg) | 550 W | -15 W, -0.6 pp | | [Seraphim SRP-555-BTB-BG](https://comparepv.com/panel/seraphim-srp-555-btb-bg) | 555 W | -10 W, -0.4 pp | | [Seraphim SRP-560-BTB-BG](https://comparepv.com/panel/seraphim-srp-560-btb-bg) | 560 W | -0.2 pp | | [Seraphim SRP-570-BTB-BG](https://comparepv.com/panel/seraphim-srp-570-btb-bg) | 570 W | Very close match | | [Seraphim SRP-575-BTB-BG](https://comparepv.com/panel/seraphim-srp-575-btb-bg) | 575 W | +10 W, +0.4 pp | | [Gamko New Energy GKA120N-PRO-590W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-590w) | 590 W | +25 W, lighter, +0.9 pp | | [Gamko New Energy GKA120N-PRO-585W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-585w) | 585 W | +20 W, lighter, +0.7 pp | | [Bisol BGO 580](https://comparepv.com/panel/bisol-bgo-580) | 580 W | +15 W, lighter, +0.6 pp | | [Gamko New Energy GKA120N-PRO-580W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-580w) | 580 W | +15 W, lighter, +0.5 pp | --- Source: https://comparepv.com/panel/seraphim-srp-565-btb-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.
