The use of **PERC monocrystalline** cells in a **half-cut** configuration helps to minimize current losses and reduces the risk of overheating in shaded areas, which in practice translates to more stable operation of the installation under real-world conditions. Compared to many standard panels, these stand out due to their refined design with **MBB (multi busbar)**, which improves current collection and supports better performance at higher module temperatures. The manufacturer also focuses on solutions that reduce microcracks and gallium doping, which is important for slower degradation over the long term. This is a good choice for premium home installations and small to medium-sized commercial roofs - especially where you expect high-quality workmanship, resistance to harsh environments, and a sleek, uniform black appearance without compromise. ## Notable figures - At 21.0% efficiency, this panel is on par with typical \*\*PERC 400-450W\*\* modules - 210.0 W/m² power density - 3.8 W/m² more than \*\*PERC 400-450W\*\* median (206.2 W/m²), more power per roof area - Temperature coefficient of -0.34%/°C matches the \*\*PERC 400-450W\*\* median - At 21.0 kg, weight matches the \*\*PERC 400-450W\*\* median - In the top 70% for efficiency among all PERC panels ## Questions ### Is the Solarspace SS8-54HSB 410-420M Lumina I series still available for purchase? The Lumina I series has been discontinued and may be difficult to source as new stock. If you need all-black PERC half-cut modules rated up to 420 Wp, check with your distributor for remaining inventory or consider a newer Solarspace series with comparable aesthetics and performance specifications. ### What warranty does the Solarspace SS8-54HSB 410-420M Lumina I carry? Solarspace provides a 12-year product warranty covering workmanship and materials, plus a 25-year linear power output warranty. Over that 25-year period the module must maintain a specified minimum output relative to its rated 410–420 Wp nameplate power, which is the standard commitment expected from Tier 1 manufacturers. ### What does half-cut PERC technology mean in the Lumina I series, and does it matter for my installation? Half-cut cells are physically split in two, reducing internal resistance and current losses within each cell. PERC adds a rear reflective passivation layer that bounces unabsorbed light back through the silicon, boosting overall efficiency. In practice this combination delivers more consistent energy output under partial shading from chimneys or antennas and higher daily energy yield compared to conventional full-cell designs. ### How does the Solarspace Lumina I perform on roofs with partial shading? The combination of half-cut cells and a multi busbar (MBB) layout means shading one section of the module has a smaller impact on the remaining cells than in conventional full-cell modules. This keeps energy yield higher under real-world conditions where perfect, unobstructed solar exposure is not always achievable, such as roofs with dormers, antennas, or neighboring structures. ### Is the Solarspace SS8-54HSB 410-420M a bifacial module? No, the Lumina I is a monofacial, all-black module. The rear surface is opaque and does not generate power from reflected irradiance. This was a deliberate design choice to achieve a uniform black appearance with no aesthetic compromises, forgoing the rear-side energy bonus that bifacial modules offer. ### Does the all-black frame and backsheet of the Lumina I negatively affect panel performance? Black surfaces can run marginally warmer under peak sun, which slightly reduces instantaneous efficiency. However, the MBB layout and gallium doping in the Lumina I help limit thermal degradation and slow long-term power loss. For a typical residential installation the practical difference is minimal, and the benefit of a uniform black roofline is typically the priority for premium-segment buyers. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ss8-54hsb-m-ed6435c83bf2.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, +2.6 pp, +5 yr warranty | | [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, +2.6 pp, +5 yr warranty | | [Luxor Solar LX-460M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-460m-182r-96-gg) | 460 W | +50 W, cooler, +2.6 pp | | [Philadelphia Solar PS-MNB108(HCBF)-460W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-460w) | 460 W | +50 W, +2.5 pp, +5 yr warranty | | [JA Solar JAT54S40-460/LR](https://comparepv.com/panel/ja-solar-jat54s40-460-lr) | 460 W | +50 W, cooler, +2.5 pp | | [Luxor Solar LX-460M/182R188-108+ GG](https://comparepv.com/panel/luxor-solar-lx-460m-182r188-108-gg) | 460 W | +50 W, +2.4 pp, +5 yr warranty | | [AIKO AIKO-455-MAH54Db](https://comparepv.com/panel/aiko-aiko-455-mah54db) | 455 W | Cooler, +2.3 pp, +5 yr warranty | | [Longi Solar LR5-54HTH-455M](https://comparepv.com/panel/longi-lr5-54hth-455m) | 455 W | +45 W, cooler, +2.3 pp | | [Solarspace SS8-54HSB-395M](https://comparepv.com/panel/solarspace-ss8-54hsb-395m) | 395 W | -15 W, -0.8 pp | | [Solarspace SS8-54HSB-400M](https://comparepv.com/panel/solarspace-ss8-54hsb-400m) | 400 W | -10 W, -0.5 pp | | [Solarspace SS8-54HSB-405M](https://comparepv.com/panel/solarspace-ss8-54hsb-405m) | 405 W | -0.3 pp | | [Solarspace SS8-54HSB-415M](https://comparepv.com/panel/solarspace-ss8-54hsb-415m) | 415 W | +0.2 pp | | [Solarspace SS8-54HSB-420M](https://comparepv.com/panel/solarspace-ss8-54hsb-420m) | 420 W | +10 W, +0.5 pp | | [Solarspace SS8-54HD-425N](https://comparepv.com/panel/solarspace-ss8-54hd-425n) | 425 W | Cooler, +0.8 pp, +5 yr warranty | | [Solarspace SS8-54HD-430N](https://comparepv.com/panel/solarspace-ss8-54hd-430n) | 430 W | Cooler, +1.0 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +100 W, cooler, +4.0 pp | --- Source: https://comparepv.com/panel/solarspace-ss8-54hsb-410m Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
