On typical Polish rooftops where module temperature reaches 65°C in summer, this translates to roughly 2.5–3 percentage points less power loss at peak summer load compared to PERC technology. - **22.3–22.8% efficiency — top of peer class** - The series reaches module efficiency of 22.3–22.8%, matching segment leaders Sunlike Solar SKT420~455M10-108D6 (22.8%) and LEDVANCE M435~455N54LB-SF-F7 (22.77%), while outperforming Waaree ARKA by over 1.37–1.87 percentage points. In practice, the same output can be achieved with a roughly 7–9% smaller roof area compared to Waaree ARKA — a critical advantage where roof space is constrained. - **30-year linear power warranty** - IBC Solar provides a 30-year performance warranty — 5 years beyond the 25-year standard offered by most competitors in this price tier. The linear degradation curve (avoiding the steep first-year drop characteristic of PERC cells) combined with full PID and LID immunity strengthens this warranty from a project bankability perspective. - **Glass-glass construction + independent quality control** - Dual-glass lamination eliminates moisture-driven degradation (MVT \< 0.001 g/m²/day vs. ≥1 g/m²/day for standard backsheet), improves mechanical resilience, and raises the fire safety class. IBC Solar AG (founded 1982, HQ Bad Staffelstein, Germany) validates every series through independent testing institutes, ensuring real-world parameter repeatability that matches datasheet values. ## Cons - **24.5 kg weight — roof load analysis required** - The glass-glass build results in a module weight of 24.5 kg, approximately 10–15% heavier than comparable N-type backsheet modules (typically 21–22 kg). For larger rooftop arrays (30+ modules), a structural load assessment and reinforced racking may be required, increasing overall BoS costs. - **Reduced bifacial gain in Full Black variant** - The opaque black rear glass of the Black LS-TA2 limits the bifacial factor (BF) to an estimated ~40–55%, whereas the sibling Transparent LS-TA2 with a clear rear glass achieves BF ~70–80%. On ground-mount or white-membrane installations with albedo >20%, the annualized yield gap versus the Transparent variant can reach 3–7%, partially negating the claimed bifacial benefit. ## About this series The IBC Solar Black LS-TA2 panel series is a proposal for the most demanding investors, combining the highest aesthetics with uncompromising technology. The use of advanced **N-type cells in TOPCon architecture** ensures that these modules are characterized by exceptional efficiency and excellent performance in low-light conditions, which is crucial in the Polish latitude. The innovative **glass-glass** construction combined with bifacial cell activity allows for the effective use of reflected light, which significantly increases the total energy yield from any roof or ground-mounted installation. This series effectively solves the problem of performance degradation over time, offering one of the most stable power curves on the market and full resistance to harmful phenomena such as PID or LID effects. Thanks to the elegant, deep black **Full Black** finish, these panels become an integral part of modern architecture, eliminating the need for compromises between high productivity and building aesthetics. This product is primarily dedicated to homeowners for whom durability measured in decades and **maximum fire safety** are priorities. What distinguishes them from market competition is rigorous quality control in independent laboratories and an exceptionally long 30-year warranty, making them one of the most secure investments in the Polish RES sector. Choosing this series is a guarantee of technical excellence and full energy independence in the most stylish form. ## Notable figures - At 22.8% efficiency, this panel is 1.0pp above typical \*\*database\*\* modules (median: 21.8%) - 227.7 W/m² power density - 9.6 W/m² more than \*\*database\*\* median (218.1 W/m²), more power per roof area - At -0.29%/°C, hot weather performance is typical for \*\*database\*\* panels - Weight of 24.5 kg (2.0 kg below \*\*database\*\* median of 26.5 kg) allows easier transport and roof mounting - Bifaciality factor of 78% can add 4-12% extra yield with reflective mounting surface ## Questions ### What is TOPCon technology in IBC Solar Black LS-TA2 panels and why is it worth paying for? TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology that minimizes electron recombination losses at the metal-silicon interface. In practice, this means module efficiency up to 22.8% and a lower temperature coefficient (-0.29%/°C) than standard PERC cells. Black LS-TA2 panels generate more energy from the same roof area and lose less output during hot summer days. ### How much extra energy do bifacial IBC Solar Black LS-TA2 panels generate? Thanks to the glass-glass construction and active rear cell surface, the IBC Solar Black LS-TA2 harvests light reflected from the ground, such as a white roofing membrane, gravel, or snow. A typical bifacial gain on a rooftop installation is 3–8%, while ground-mounted systems can see up to 15% additional yield. The exact value depends on surface albedo and array tilt angle. ### What warranty does the IBC Solar Black LS-TA2 series carry and what does it cover? The Black LS-TA2 series comes with a 25-year product warranty covering material and manufacturing defects, plus a 30-year linear power warranty. After 30 years, the module is guaranteed to retain at least 89.4% of its rated power output. This is one of the longest warranties available on the Polish renewable energy market, reflecting IBC Solar's confidence in the durability of N-type TOPCon cells. ### Do IBC Solar Black LS-TA2 panels perform well in Poland's climate with limited sunlight? Yes, the Black LS-TA2 series is well suited to Polish climate conditions. The low temperature coefficient (-0.29%/°C) means the panels outperform standard PERC cells during heat waves, while the excellent low-irradiance characteristics of N-type cells deliver higher energy yield on overcast days and during morning and evening hours, which account for a significant share of solar exposure in Poland. ### Does the Full Black finish of the IBC Solar Black LS-TA2 negatively affect performance? The Full Black finish causes slightly higher heat absorption compared to variants with a white rear glass, but the impact on annual energy yield is marginal. Black LS-TA2 modules achieve the same rated power up to 455 Wp as the transparent variant, maintaining a uniform black appearance ideal for modern residential buildings without any meaningful efficiency trade-off. ### How heavy is the IBC Solar Black LS-TA2 and can it be installed on a standard pitched roof? The IBC Solar Black LS-TA2 weighs 24.5 kg and measures 1762 × 1134 × 30 mm. This is a standard size for pitched roof installations with tilt angles between 15° and 60°. The weight is within normal limits for a two-person installation crew, and the 30 mm frame depth ensures compatibility with standard mounting rail systems used by most installers in Poland. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ibc-module-black-450-ls-ta2-123e95525903.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +40 W, lighter, +2.0 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +50 W, cooler, +1.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +35 W, lighter, +1.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +45 W, cooler, +1.7 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +45 W, lighter, +1.7 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | +45 W, lighter, +1.7 pp | | [IBC Solar IBC MonoSol 430 MS10-HC-N GEN2](https://comparepv.com/panel/ibc-solar-ibc-monosol-430-ms10-hc-n-gen2) | 430 W | -25 W, lighter, -1.3 pp | | [IBC Solar IBC MonoSol 435 MS10-HC-N GEN2](https://comparepv.com/panel/ibc-solar-ibc-monosol-435-ms10-hc-n-gen2) | 435 W | -20 W, lighter, -1.0 pp | | [IBC Solar IBC Module White 440 MS-TA1](https://comparepv.com/panel/ibc-solar-ibc-module-white-440-ms-ta1) | 440 W | -15 W, lighter, -0.8 pp | | [IBC Solar IBC Module White 445 MS-TA1](https://comparepv.com/panel/ibc-solar-ibc-module-white-445-ms-ta1) | 445 W | Hotter, lighter, -0.5 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +55 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/ibc-solar-black-455-ls-ta2 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.
