Higher efficiency directly reduces the roof or ground area required to achieve the target system output. - **N-type TOPCon cell technology** - N-type TOPCon cells exhibit a lower annual degradation rate (~0.40%/year after year 1 vs. ~0.45–0.50% for PERC) and reduced LID losses. Over a 30-year operating horizon, the cumulative energy production difference amounts to several percentage points — translating to hundreds of additional kWh per year for a 10 kWp system toward the end of the warranty period. - **30-year linear power warranty, German guarantor** - IBC Solar AG provides a 30-year linear power performance warranty backed by the German-registered entity (Bad Staffelstein). This offers meaningful legal security for EU investors: the warranty obligation falls under German jurisdiction, and the company has operated continuously since 1982. - **Bifacial glass-glass construction** - The bifacial design enables additional energy harvest from ground-reflected irradiance (typical bifacial gain: 5–12% at 0.25–0.40 ground albedo for ground-mount applications). The glass-glass laminate provides superior moisture barrier performance (lower WVTR) and better resistance to microcracks compared to standard backsheet modules, extending real-world service life. - **Pricing below European median** - The retail price for the 455 Wp variant is approximately €0.235/Wp (European distributors, June 2025–2026), below the estimated European median for comparable TOPCon modules of ~€0.27/Wp. The series therefore delivers a better price-to-performance ratio than the premium brand positioning might suggest. ## Cons - **No BNEF Tier 1 status** - IBC Solar AG does not appear on the BNEF Tier 1 PV Module Manufacturers list for Q1 2026. Tier 1 status is required by most lenders and insurers for utility-scale and PPA-backed projects. Commercial installations above 1 MWp may face difficulties securing project finance or insurance if the specification mandates modules from a verified Tier 1 manufacturer. - **Limited scale and balance-sheet depth of guarantor** - IBC Solar AG is a company with estimated revenues of €250–500M and 250–499 employees — many times smaller than Jinko Solar (>120 GW/year) or Trina Solar. The strength of a 30-year warranty is directly correlated with the financial health of the guarantor. The absence of holding-group capital backing increases residual risk for long-term institutional investors. ## About this series The IBC Solar IBC Module Transparent 445-455 LS-TA2 series is a range of modules designed for high energy yields in real-world conditions and long-term, trouble-free operation. The use of **TOPCon technology** and modern monocrystalline cells in a **half-cut** configuration improves performance under partial shading and reduces losses that quickly decrease energy production in standard panels. A key advantage is the **bifacial, two-sided design** - the module can utilize light reflected from the ground, which is crucial when every kilowatt-hour counts. The Transparent version also stands out for its refined aesthetics and the use of a **glass-to-glass structure**, which provides better protection against moisture, micro-cracks, and faster material degradation. This solution is ideal for demanding rooftop and ground-mounted installations, including commercial projects, where stability, durability, and predictable returns are paramount. When compared to typical PERC modules, you gain a more modern cell architecture and improved performance over a longer period. ## Notable figures - Efficiency of 22.8% matches the \*\*TOPCon 450-500W\*\* median - Power density of 227.7 W/m² matches the \*\*TOPCon 450-500W\*\* median - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 450-500W\*\* median - Bifacial design (78% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof - #2714 for efficiency, #2165 for temperature performance out of 14005 panels ## Questions ### What warranty comes with the IBC Module Transparent 445–455 LS-TA2 panels? The IBC Module Transparent 445–455 LS-TA2 series comes with a 25-year product warranty and a 30-year power output guarantee. IBC Solar AG, headquartered in Germany, acts as the guarantor, which significantly reduces counterparty risk for long-term commercial and residential investments. ### What is bifacial technology and how much additional energy can the LS-TA2 Transparent module generate with it? Bifacial means the module generates electricity from both sides — the front absorbs direct irradiance while the rear captures light reflected from the ground (e.g., white roofing membrane, light gravel, or snow). IBC Solar claims up to 25% higher yield compared to a comparable monofacial module. Actual gains depend on the albedo of the surface beneath the array and the tilt angle of the installation. ### How does the IBC Module Transparent LS-TA2 compare to standard PERC panels available on the market? The key difference is cell architecture: the LS-TA2 uses TOPCon technology, which minimizes carrier recombination and delivers up to 22.8% module efficiency with slower long-term degradation. Typical PERC modules stay below 21.5% efficiency. The glass-glass construction of the Transparent series also provides better protection against moisture ingress and micro-cracking compared to standard PERC modules with a polymer backsheet. ### Is the IBC Module Transparent 455 LS-TA2 suitable for a pitched roof in a residential installation? Yes, though the weight is worth considering: the module weighs 24.5 kg with dimensions of 1762 × 1134 × 30 mm, which is slightly heavier than lighter backsheet modules. The glass-glass construction requires mounting clamps certified for dual-glass modules. The panel withstands up to 5400 Pa front-side load, making it suitable for roofs exposed to wind and snow. Half-cut cell technology also reduces losses from partial shading by chimneys or dormers. ### How does the IBC Module Transparent LS-TA2 series perform on overcast days and during hot summer temperatures? TOPCon technology provides a low temperature coefficient (typically around -0.30%/°C), meaning smaller power losses on hot days compared to older cell generations. On overcast days the bifacial advantage is limited due to low ground albedo, but monocrystalline half-cut cells maintain relatively high efficiency under diffuse irradiance thanks to the lower threshold voltage of individual cell segments. ### Are the IBC Module Transparent 445–455 LS-TA2 modules compatible with standard inverters and racking systems? Yes. The modules operate within voltage and current ranges compatible with standard string inverters and microinverters widely available on the market. Open-circuit voltage Voc reaches up to approximately 40.45 V (455 Wp model) and Isc up to 14.24 A, fitting within the input parameters of most common inverters. The glass-glass construction requires clamps certified for dual-glass modules, which are readily available from standard racking suppliers. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/2006300027-ibc-module-transparent-455-ls-ta2-datenblatt-de-8fea7053da76.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-ibc-module-transparent-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.
