The full, black design - black solar cells, background, and frame - ensures a consistent appearance on graphite-colored roofing tiles, metal roofing, and modern facades, without the unsightly "patch" effect on the roof. The use of **half-cut** technology (split cells) minimizes losses in partial shading and reduces thermal loads, which translates to more stable performance in hot weather. The **multi busbar** system improves power collection and increases resistance to micro-cracks, which means a lower risk of power drops over time. Additionally, the **anti-reflective** coating on the glass supports better light utilization in low-sunlight conditions, which are common in Poland. This is a good choice for investors who want a **premium, aesthetically pleasing** installation without compromising on performance - for homes, small businesses, and projects where both appearance and predictable energy production are important. ## Notable figures - Efficiency of 20.6% matches the \*\*PERC 400-450W\*\* median - At 206.2 W/m² power density, roof space requirements are typical for \*\*PERC 400-450W\*\* panels - At -0.33%/°C, hot weather performance is typical for \*\*PERC 400-450W\*\* panels - At 24.0 kg, this panel is 2.0 kg heavier than the \*\*PERC 400-450W\*\* median (22.0 kg) - more demanding for installation crews - Bifaciality factor of 70% can add 4-10% extra yield with reflective mounting surface ## Questions ### Are Sunova TS-BB60 (All Black) panels suitable for a sloped roof with ceramic tiles? Yes, the fully black design - black cells, backsheet, and frame - was specifically created for sloped roofs covered with ceramic tiles, graphite-colored metal roofing, or modern facades. The panel blends into the roof color instead of creating a visible patch, which matters for installations visible from the street or yard. ### What warranty comes with Sunova TS-BB60 modules? Sunova provides a 15-year product warranty (covering material and workmanship defects) and a 25-year power output warranty, which is standard for the premium segment. Note that Sunova is not a tier 1 manufacturer, so it's worth checking the local distributor and warranty service terms available in your market before purchasing. ### What is half-cut technology in the TS-BB60 panels and does it actually make a difference? Half-cut means the cells are split in half, which reduces current losses under partial shading, such as from a chimney or antenna, and lowers thermal stress on the module. In practice this results in more stable panel performance during hot weather and smaller yield drops when part of the array is shaded. ### Is the Sunova TS-BB60 bifacial, and is it worth it on a sloped roof? Yes, the TS-BB60 series uses bifacial cells that can capture additional reflected light from the ground on the rear side of the module. On a typical sloped roof with a narrow gap beneath the panels, the bifacial gain is limited, but the effect is more noticeable on ground-mounted structures or flat roofs with elevated racking. ### What is the maximum power output of the Sunova TS-BB60, and how many panels are needed for a typical 5 kWp system? The maximum module power is 460 Wp. Building a system of roughly 5 kWp requires about 11 such panels, though the exact number depends on inverter sizing and roof tilt angle. Thanks to PERC cell technology and the multi busbar layout, the modules maintain stable output even under low irradiance. ### How do the PERC cells in the TS-BB60 differ from newer TOPCon technology? PERC cells used in the TS-BB60 are a mature, proven technology offering a good price-to-efficiency ratio, while TOPCon typically delivers slightly higher efficiency and better high-temperature performance at a higher cost. The TS-BB60 is a solid choice when the priority is the All Black aesthetic and a reasonable budget rather than the highest efficiency on the market. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/thornova-ts-bb60-445-460-all-black-3b60988bcfe0.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +50 W, cooler, +4.2 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, +3.9 pp, +5 yr warranty | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | Cooler, +3.9 pp, +5 yr warranty | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | Cooler, +3.7 pp, +5 yr warranty | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | Cooler, +3.7 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-495M](https://comparepv.com/panel/longi-lr7-54hjd-495m) | 495 W | +50 W, cooler, +3.7 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | Cooler, +3.7 pp, +5 yr warranty | | [Sunova TS-BG60(450)](https://comparepv.com/panel/sunova-ts-bg60-450) | 450 W | Heavier, +0.2 pp, +5 yr warranty | | [Sunova TS-BG60(455)](https://comparepv.com/panel/sunova-ts-bg60-455) | 455 W | Heavier, +0.5 pp, +5 yr warranty | | [Sunova TS-BG60(460)](https://comparepv.com/panel/sunova-ts-bg60-460) | 460 W | Heavier, +0.7 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +115 W, cooler, +4.2 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +110 W, cooler, +4.0 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +105 W, lighter, +3.8 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +95 W, cooler, +3.8 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +95 W, cooler, +3.8 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | +100 W, cooler, +3.6 pp | --- Source: https://comparepv.com/panel/sunova-ts-bb60-445 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.
