The use of monocrystalline cells in the **PERC** technology helps to better utilize diffuse light, which is important in the Polish climate with frequent cloud cover. The **dual glass** (glass on both sides) construction improves rigidity and protects the laminate from moisture and micro-cracks, resulting in longer, trouble-free operation. The **full black** variant is ideal for installations where aesthetics are also important - on modern buildings, office buildings, or warehouses with representative facades. The TS-BG60 also features a **positive power tolerance**, which means that the actual performance of the module often matches the expectations from the project. This makes it a good choice for companies that want to reduce energy costs, increase self-consumption, and acquire reliable modules for years to come. ## Notable figures - At 20.9% efficiency, this panel is on par with typical \*\*PERC 450-500W\*\* modules - At 208.5 W/m² power density, roof space requirements are typical for \*\*PERC 450-500W\*\* panels - At -0.33%/°C, hot weather performance is typical for \*\*PERC 450-500W\*\* panels - At 26.3 kg (1.8 kg above \*\*PERC 450-500W\*\* median of 24.5 kg), requires checking roof load capacity - 70% bifaciality enables rear-side power generation, boosting yield by 4-10% on reflective surfaces ## Questions ### How is the Sunova TS-BG60 different from standard monofacial panels? The TS-BG60 is a bifacial module built in a dual glass configuration, with glass on both the front and back instead of a standard backsheet. This lets the rear side also capture light reflected from the roof or ground, potentially boosting energy yield when installed correctly. The glass-glass structure also adds rigidity and protects the laminate from moisture and micro-cracks. ### What warranty comes with the Sunova TS-BG60 series? The TS-BG60 series carries a 15-year product warranty and a 30-year power output warranty. This means protection against material and workmanship defects for 15 years, while the 30-year term guarantees a defined level of power output according to the module's linear degradation curve. ### Is the TS-BG60 suitable for commercial and industrial roofs? Yes, the TS-BG60 series is designed for commercial and industrial roof installations where durability and predictable energy yield at scale matter most. The dual glass construction adds extra mechanical resistance, and power output up to 460 Wp reduces the number of modules needed to cover large roof areas. ### What does positive power tolerance mean for the Sunova TS-BG60? Positive power tolerance means the actual output of the module never falls below its rated nameplate value and is often slightly higher. As a result, TS-BG60 installations more consistently meet or exceed design expectations, leading to a more predictable energy yield compared to panels with negative tolerance. ### Does the full black version of the TS-BG60 have lower efficiency? The full black variant (black frame and black backing) on PERC-based series can run slightly hotter than white-backsheet versions, resulting in a marginally lower yield on very hot days. The difference is minor, and the aesthetic appeal makes it a good fit for showcase buildings, office facades, and modern industrial halls. ### Who manufactures Sunova panels, and is it a tier 1 supplier? Sunova is a photovoltaic manufacturer headquartered in China with a presence in the global renewable energy market. The brand is not listed as a tier 1 manufacturer (BloombergNEF's classification for financial stability and bankability), which is worth considering for projects financed through loans or leasing, though it does not directly affect the technical quality of the modules themselves. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/thornova-ts-bg60-445-460-v2023-11-20-b48560c52563.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +3.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +3.6 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +50 W, cooler, +3.6 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +50 W, cooler, +3.6 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | +50 W, cooler, +3.6 pp | | [GCL GCL-NR10R/54BGDF](https://comparepv.com/panel/gcl-gcl-nr10r-54bgdf) | 500 W | +50 W, cooler, +3.6 pp | | [Sunova TS-BB60(445)](https://comparepv.com/panel/sunova-ts-bb60-445) | 445 W | Lighter, -0.2 pp, -5 yr warranty | | [Sunova TS-BG60(455)](https://comparepv.com/panel/sunova-ts-bg60-455) | 455 W | +0.2 pp | | [Sunova TS-BG60(460)](https://comparepv.com/panel/sunova-ts-bg60-460) | 460 W | +10 W, +0.5 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +110 W, cooler, +3.9 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +105 W, cooler, +3.8 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +100 W, lighter, +3.5 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +90 W, cooler, +3.5 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +90 W, cooler, +3.5 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | +95 W, cooler, +3.4 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | +95 W, cooler, +3.3 pp | --- Source: https://comparepv.com/panel/sunova-ts-bg60-450 Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
