It is the only series on the market enabling full replacement of roof cladding with PV modules while maintaining a uniform aesthetic, a decisive advantage for heritage buildings and premium projects where standard black modules are not permitted. - **30-Year Power Warranty with 85% Retention at Year 25** - The manufacturer guarantees 85% of nominal power output after 25 years, significantly exceeding the industry-standard 80% threshold applied by peers such as VDS Renewable and Sunket in this power class. The product warranty runs for 25 years, with full linear protection extending to 30 years. - **European Manufacturer with a 0.01% Warranty Claim Rate** - BISOL has manufactured modules in Slovenia since 2004, in compliance with IEC 61215 and IEC 61730. The declared warranty claim rate is just 0.01% — one of the lowest in the European segment. The company has earned the EuPD Research Top Brand title four times in Belgium and France, confirming its brand recognition and quality reputation in Western European markets. - **3.2 mm Tempered Glass** - Modules are fitted with 3.2 mm tempered glass, delivering superior mechanical resistance to snow and wind loads compared to thinner glazing solutions (1.2–2.0 mm used by some manufacturers in this segment). This is particularly significant in BIPV installations, where the module simultaneously functions as a structural building element. - **Full Visual Customization for Developers and Architects** - The ability to freely select cell background color and frame finish from the RAL palette gives architects a design tool unavailable in any of the peer comparables (VDS Renewable, Sunket, Luxor Solar). This translates into a tangible competitive edge in commercial projects and public buildings subject to heritage conservation restrictions. ## Cons - **Efficiency Below the Peer Comparable Benchmark** - The series reaches a maximum efficiency of 20.5%, while the Luxor Solar Eco Line N-type TOPCon achieves 21.33% and the Sunket SKT410M10 reaches 21.0% at the same 410 Wp power class. The gap is partly attributable to the cell coloring technology, but in installations with limited roof area it can translate into measurably lower energy yield compared to conventional, non-colored alternatives. - **No Bifacial Option** - The series does not offer bifacial modules, whereas a direct peer comparable — the Luxor Solar Eco Line N-type TOPCon Glass-Glass — is available as a bifacial module in the same 410 Wp power class. In ground-mounted systems or pergola applications, bifaciality can increase annual energy yield by 5–15%, a benefit the Spectrum series cannot provide. - **No Tier 1 Bankable Status** - BISOL does not appear on the bankable manufacturer lists published by BNEF or Bloomberg NEF Tier 1. For investors financing installations through bank loans or leasing, this may represent a barrier — certain financial institutions require products from manufacturers with certified bankability status as a precondition for project financing. ## About this series The BISOL Spectrum series is a response to the growing market demand for **aesthetically pleasing photovoltaic panels integrated with architecture**. Unlike standard modules, Spectrum offers a wide range of **color-tinted monocrystalline solar cells** - from deep red and terracotta orange, through forest green and marble patterns, to alabaster white - allowing for seamless integration of the installation into the building's facade or roof. The modules are available as a **BIPV (Building Integrated Photovoltaics) solution**, where specially framed panels completely replace traditional roofing, creating a uniform and architecturally cohesive surface. The frame is available in any color from the RAL palette, and the background color of the cells can be customized to the design, giving architects and investors complete freedom of creation. The series is particularly well-suited for historic buildings, premium apartment complexes, public buildings, and commercial investments, where aesthetics are as important as performance. The tempered glass provides high resistance to weather conditions, and the **guarantee of 85% power retention after 25 years** significantly exceeds the market standard of 80%, making Spectrum a conscious choice for demanding architects and investors seeking a **durable and effective energy solution**. ## Notable figures - Efficiency of 20.5% matches the \*\*PERC 400-450W\*\* median - Power density of 205.2 W/m² matches the \*\*PERC 400-450W\*\* median - At -0.29%/°C (vs median -0.35%/°C), loses ~2% less power in hot conditions - At 21.0 kg, weight matches the \*\*PERC 400-450W\*\* median - In the top 81% for efficiency among all PERC panels ## Questions ### What colors are available for BISOL Spectrum panels, and does color affect their efficiency? BISOL Spectrum offers monocrystalline cells in several color variants: deep red, terracotta orange, forest green, marble patterns, and alabaster white. Color does affect efficiency — pigmented cells absorb slightly less light than standard dark-blue cells, so module efficiency ranges from approximately 19% (red variants) to approximately 20.5% (green variant). The frame is available in any RAL palette shade, providing complete freedom to match any architectural design. ### What are BISOL Spectrum BIPV panels and how do they differ from a conventional photovoltaic installation? BISOL Spectrum in the BIPV (Building Integrated Photovoltaics) variant fully replaces a conventional roofing material or façade cladding — the modules are not mounted on top of the roof but become an integral structural part of it. In a standard PV installation, panels are added on top of an existing roof covering. The BIPV solution eliminates the cost of traditional roofing material, maintains the architectural coherence of the building, and is particularly recommended for listed heritage buildings, premium apartment complexes, and public-use facilities. ### What warranty does BISOL Spectrum carry, and how does it compare to competing products? BISOL Spectrum is covered by a 25-year product warranty and a 30-year power output warranty. The manufacturer guarantees that modules will retain at least 85% of their nominal power after 25 years of operation, whereas the industry standard is 80%. The extended power warranty window (30 years) and the higher degradation threshold indicate superior module durability and are particularly significant for long-term investments such as commercial buildings or premium residential developments. ### Are BISOL Spectrum panels suitable for the renovation of a listed heritage building or a historic tenement? Yes, the Spectrum series was specifically designed with such applications in mind. The colored monocrystalline cells and the frame available in any RAL shade allow the panel appearance to be matched to a historic façade or roof covering, which facilitates obtaining approval from heritage preservation authorities. BIPV modules replace the traditional roofing material, so they do not alter the building's profile or massing. With power output reaching 410 Wp, effective energy generation is achievable even on roof surfaces with limited area. ### Is the BISOL Spectrum a bifacial panel, and is it worth choosing over a bifacial module? No, BISOL Spectrum is not a bifacial module. The monocrystalline cells in this series feature a single-sided colored coating, which is a deliberate compromise in favor of full color flexibility and aesthetic architectural integration. If the priority is maximum energy yield per square meter — for example, on a white surface or a ground-mounted array — a bifacial panel will be the more advantageous choice. Spectrum is the right selection when aesthetics and architectural harmony are equally as important as energy performance. ### Where are BISOL Spectrum panels manufactured, and is the manufacturer ranked as a Tier 1 producer? BISOL is a Slovenian manufacturer headquartered in Šempeter pri Gorici. The company does not appear on the Bloomberg NEF Tier 1 list, which primarily covers the largest high-volume producers. This does not imply lower quality — BISOL is a European niche manufacturer specializing in BIPV modules and colored panels for demanding clients. This is evidenced by the 30-year power warranty with an 85% retention threshold after 25 years, which exceeds the standard terms offered by most companies on the Tier 1 list. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/BISOL_Spectrum_EN-dbb27cd20ec5.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A460-MAH54Mb](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a460-mah54mb-1) | 460 W | +50 W, +3.1 pp | | [Just Solar JST-EDMH-(445-465)W-TD (460W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-460w-class) | 460 W | +50 W, hotter, +3.1 pp | | [Luxor Solar LX-460M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-460m-182r-96-gg) | 460 W | +50 W, cooler, +3.1 pp | | [Philadelphia Solar PS-MNB108(HCBF)-460W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-460w) | 460 W | +50 W, +3.0 pp | | [JA Solar JAT54S40-460/LR](https://comparepv.com/panel/ja-solar-jat54s40-460-lr) | 460 W | +50 W, cooler, +3.0 pp | | [Luxor Solar LX-460M/182R188-108+ GG](https://comparepv.com/panel/luxor-solar-lx-460m-182r188-108-gg) | 460 W | +50 W, heavier, +2.9 pp | | [AIKO AIKO-455-MAH54Db](https://comparepv.com/panel/aiko-aiko-455-mah54db) | 455 W | +45 W, heavier, +2.8 pp | | [Longi Solar LR5-54HTH-455M](https://comparepv.com/panel/longi-lr5-54hth-455m) | 455 W | +45 W, +2.8 pp, -5 yr warranty | | [Bisol BDO 360](https://comparepv.com/panel/bisol-bdo-360) | 360 W | -50 W, -2.5 pp | | [Bisol BDO 440](https://comparepv.com/panel/bisol-bdo-440) | 440 W | +30 W, +1.5 pp | | [Bisol BDO 450](https://comparepv.com/panel/bisol-bdo-450) | 450 W | +40 W, +2.0 pp | | [Bisol BDO 460](https://comparepv.com/panel/bisol-bdo-460) | 460 W | +50 W, +2.5 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +100 W, cooler, +4.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +85 W, cooler, +4.3 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +95 W, cooler, +4.2 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +80 W, cooler, +4.0 pp | --- Source: https://comparepv.com/panel/bisol-bdo-410 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
