This extends the investment security horizon by 5 years at no additional cost. - **Fire Class A Rating and HW3 Hail Resistance** - The series holds the highest Fire Class A certification per IEC 61730, along with certified HW3 hail resistance. This enables unrestricted installation on pitched roofs in close proximity to other structures and satisfies the requirements of the most stringent insurance underwriters. - **N-Type TOPCon in Glass-Glass Construction** - N-type TOPCon cells eliminate light-induced degradation (LID) and potential-induced degradation (PID), while the dual-glass construction provides mechanical load resistance up to 620 kg/m². This combination minimizes long-term degradation and is particularly advantageous in climates with high temperature cycling and humidity. - **Bifacial: Up to +30% Yield Gain from the Rear Side** - The bifacial design enables an additional +10% to +30% energy harvest from reflected irradiance captured by the rear side of the module. In ground-mount or light-colored rooftop installations, this translates into a measurably higher annual energy yield without increasing the number of modules. - **All-Black Aesthetics Without Quality Compromise** - The deep-black frame and cells meet the aesthetic demands of modern residential construction while retaining the full 30-year warranty and Fire Class A certification — unlike many lower-cost all-black alternatives from competitors that frequently sacrifice bifacial capability or glass-glass construction to achieve a lower price point. ## Cons - **Efficiency 1.5–2.3 pp Below Peer Class** - The maximum module efficiency of the SUPERBLACK series is 21.95%, while direct peer comparables — JA Solar JAM54D40 LB and Astronergy ASTRO N7s 2.0 — reach 23.8%, and Longi Hi-MO X10 Explorer reaches 23.3%. The 1.5–2.3 percentage-point gap means approximately 7–11% more roof area is required to achieve the same total system power output. - **Not Listed as BNEF Tier-1 Bankable Manufacturer** - Bauer Solar does not appear on the BNEF Tier-1 bankable manufacturers list (source: context; BNEF 2025 verification). This may limit access to project finance structures relying on non-recourse debt and poses a risk to long-term manufacturer warranty continuity over the full 30-year asset life. ## About this series Bauer Solar SUPERBLACK series photovoltaic panels are synonymous with aesthetic minimalism combined with the highest technological efficiency, dedicated to the most demanding home systems. The use of advanced **N-Type cells** in a durable **glass-glass** construction effectively eliminates the problem of degradation caused by light and moisture, which translates into decades of trouble-free operation.

Thanks to the use of **bifacial technology**, these modules effectively absorb reflected light also from the rear side, which significantly increases the efficiency of the installation even in worse weather conditions. They are ideal for modern single-family housing, where the deep black of the frame and cells creates a uniform, luxurious surface without visible connections. What distinguishes SUPERBLACK from standard competitor products is, above all, **increased resistance to mechanical loads** and rigorous quality control, guaranteeing the highest level of fire safety. By choosing this solution, the user receives a premium class product that not only drastically reduces electricity bills, but also significantly increases the aesthetic value of the entire property. ## Notable figures - Efficiency of 21.5% is 1.0pp below the \*\*TOPCon 450-500W\*\* median (22.5%) - 214.9 W/m² power density is 10.3 W/m² below \*\*TOPCon 450-500W\*\* median (225.2 W/m²) - requires larger installation area - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 450-500W\*\* panels - At 26.7 kg (2.7 kg above \*\*TOPCon 450-500W\*\* median of 24.0 kg), requires checking roof load capacity - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof ## Questions ### What warranty do Bauer Solar SUPERBLACK panels offer and what does it cover? The SUPERBLACK series is backed by both a 30-year product warranty and a 30-year linear power output warranty. This means the manufacturer guarantees that module efficiency will be maintained at a minimum of 87.4% after 30 years of operation. This represents one of the longest and most comprehensive warranties available in the premium photovoltaic panel market. ### What does TOPCon technology mean in the SUPERBLACK panels and why is it superior to PERC? TOPCon is a next-generation N-Type cell technology that delivers higher energy conversion efficiency and a significantly lower degradation rate compared to conventional PERC cells. Bauer Solar SUPERBLACK modules with TOPCon lose less power per year than their PERC counterparts, which over a 30-year period translates into measurably greater energy yield and a faster return on investment. ### Do Bauer Solar SUPERBLACK panels perform effectively under overcast skies or in shading conditions? Yes. Thanks to the bifacial design with dual-sided light absorption, the SUPERBLACK series makes better use of diffuse irradiance on cloudy days. The rear side of the module captures light reflected from the roof surface or ground, increasing energy yield by up to several percentage points compared to monofacial modules. An additional benefit is the half-cut cell technology, which minimizes power losses under partial shading conditions. ### Are SUPERBLACK modules suitable for installation on a pitched roof of a single-family home? Yes, the SUPERBLACK series is purpose-designed for prosumer installations on pitched roofs. The glass-glass construction provides high mechanical rigidity and resistance to wind and snow loads. The uniform, deep-black surface of both the frame and cells allows the panels to integrate aesthetically with modern roof tiles or metal roofing, without compromising the appearance of the building facade. ### How do Bauer Solar SUPERBLACK panels differ from standard black panels available on the market? The key differentiators are N-Type TOPCon cell technology instead of the less advanced PERC, a dual-glass glass-glass construction instead of a glass-backsheet design, and bifacial capability enabling light absorption from both sides. In addition, the SUPERBLACK series holds a Fire Class A certification (IEC), resulting in a higher level of fire safety. Peak power output reaches 475 Wp while maintaining a fully aesthetic appearance with no visible busbars or cell interconnects. ### Is Bauer Solar a reputable manufacturer and where is the company headquartered? Bauer Solar (Bauer Solartechnik GmbH) is a manufacturer headquartered in Germany, designing modules in accordance with European quality standards. The brand is not currently listed on the Bloomberg NEF Tier 1 index; however, it offers some of the longest warranties on the market — 30 years for both product and power output — along with rigorous quality control confirmed by relevant certifications. Before purchasing, it is advisable to verify the availability of an authorized service center and distributor in Poland. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Bauer-470-W-TOPCon-Superblack-Datasheet-a005adc210fd.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +45 W, cooler, +3.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +3.3 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +40 W, cooler, +3.2 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +3.0 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +35 W, cooler, +3.0 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | Cooler, lighter, +3.0 pp | | [Bauer Solar BS-470-120M10NHBB-GG](https://comparepv.com/panel/bauer-solar-bs-470-120m10nhbb-gg) | 470 W | +0.2 pp | | [Bauer Solar BS-475-120M10NHBB-GG](https://comparepv.com/panel/bauer-solar-bs-475-120m10nhbb-gg) | 475 W | +10 W, +0.5 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +95 W, cooler, +3.3 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +90 W, cooler, +3.1 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +85 W, lighter, +2.9 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +75 W, cooler, +2.9 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +75 W, cooler, +2.9 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | +80 W, cooler, +2.8 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | +80 W, cooler, +2.7 pp | --- Source: https://comparepv.com/panel/bauer-solar-bs-465-120m10nhbb-gg Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
