The IBC Solar IBC Module Black 445-455 LS-TA2 series is designed to combine high performance, aesthetics, and durability for years to come in a single module. These panels, with a glass-glass construction, provide better protection for the cells against moisture, material fatigue, and typical operational loads - particularly in installations intended to operate reliably for extended periods. The use of N-type cells with TOPCon technology supports more stable energy production over the long term and helps to minimize performance losses associated with aging.

The modules are bifacial, meaning they can also utilize light reflected from the ground - a real advantage on bright roofs, facades, carports, and ground-mounted structures. The half-cut technology improves performance under partial shading and ensures consistent operation throughout the day. The overall sleek, consistent black design complements modern buildings and premium installations, setting the LS-TA2 series apart from standard modules.

What owners get
Temperature coefficient -0.29%/°C

The N-type TOPCon cells in the LS-TA2 series deliver a power temperature coefficient of -0.29%/°C, notably better than PERC (~-0.35%/°C). At a cell temperature of 45°C, that difference translates to roughly 3% higher output — meaningful under Central European irradiance conditions.

22.3–22.8% efficiency — top of segment

Peak efficiency of 22.8% matches Sunlike Solar SKT455 (22.8%) and LEDVANCE M455 (22.77%), while outperforming Waaree ARKA Series (20.93%) by nearly 9 percentage points. For a fixed roof area, the LS-TA2 generates approximately 9% more energy than the Waaree peer comparable.

30-year power warranty

IBC Solar backs the series with a 30-year performance warranty and a 25-year product warranty — above the 25/25-year market standard common among 445–455 Wp competitors. The extended horizon directly lowers LCOE and improves bankability for project financing.

Glass-glass construction 2.0+2.0 mm

IBC Solar specifies 2.0 mm front and rear glass, thicker than the 1.6 mm panes used by some peers. This eliminates moisture ingress through the backsheet, improves resistance to mechanical loading, and confirms suitability for BIPV applications such as facades and carports.

Manufacturer with 40+ years of history, HQ Germany

IBC Solar AG has operated continuously since 1982 as an independent European PV integrator and module brand. Its long industry track record, European technical support, and absence of speculative startup risk underpin the credibility of its 25–30-year warranty obligations.

Trade-offs
Weight ~24.5 kg — heavier than glass-backsheet

The glass-glass construction results in a module weight of ~24.5 kg, roughly 15–20% more than comparable 455 Wp glass-backsheet modules (~20–22 kg). Retrofit installations on older roof structures may require a structural load assessment prior to mounting, potentially increasing project cost and timeline.

Common questions

6 answered
What warranty does the IBC Module Black 445–455 LS-TA2 series come with?
The IBC Module Black 445–455 LS-TA2 comes with a 25-year product warranty covering material and workmanship defects, plus a 30-year linear power warranty. For three decades, IBC Solar guarantees module output will remain above the specified degradation threshold. This is one of the longer combined warranty packages available for premium residential and commercial PV modules on the European market.
What does the glass-glass construction of the LS-TA2 mean in practice — is it worth the premium?
Glass-glass construction replaces the standard rear backsheet with a second tempered glass layer. In the LS-TA2 series, this delivers significantly better protection against moisture ingress, UV exposure, and mechanical fatigue under variable loads. The result is slower long-term degradation and extended service life — particularly relevant for demanding applications such as carports, building-integrated facades, and commercial rooftop systems exposed to harsh weather conditions.
How do the IBC Module Black LS-TA2 panels perform during winter and overcast conditions?
The N-type TOPCon cells used in the LS-TA2 series feature a low temperature coefficient of -0.29 %/°C, meaning less power loss at high temperatures compared to PERC technology. In colder months, the modules operate more efficiently. The inherently low LID (Light Induced Degradation) of N-type cells contributes to more stable energy yield throughout the entire year.
Do the bifacial IBC LS-TA2 modules actually generate more energy than standard single-sided panels?
Yes — the bifacial design of the LS-TA2 series allows the rear side to absorb reflected light from the ground or surface below, potentially adding several to over ten percent in energy yield compared to monofacial modules. The actual gain depends on surface albedo: light-colored roofing membranes, white gravel, or concrete deliver the best results. Applications such as carports, ground-mounted systems, and building-integrated facades benefit the most.
What are the dimensions and weight of the IBC Module Black 455 LS-TA2 — is installation challenging?
The IBC Module Black 455 LS-TA2 measures 1762 × 1134 × 30 mm and weighs 24.5 kg. This is a standard footprint for a 108-cell module in this power class, comparable to most premium panels on the market. Two-person installation is standard; on steep-pitch roofs appropriate fall-protection equipment is recommended. The 30 mm frame depth and glass-glass construction require mounting rails and clamps rated for the module's weight and edge profile.
How does TOPCon technology in the IBC LS-TA2 series differ from mainstream PERC cells?
TOPCon (Tunnel Oxide Passivated Contact) cells use an N-type base with an ultra-thin tunnel oxide passivation layer that reduces carrier recombination and improves efficiency. The LS-TA2 series reaches up to 22.8% module efficiency — a clear step above typical PERC modules at 20–21%. TOPCon also exhibits lower LID and better high-temperature behavior, translating into higher energy yield over the full lifetime of the installation.
