The use of **N-type TOPCon** cells minimizes losses due to initial degradation and over the long term, leading to more predictable and financially sound project results. The module utilizes a **bifacial dual-glass** construction, enabling it to effectively utilize reflected light from the ground - a significant advantage in PV farms, carports, and roofs with light-colored surfaces. Thanks to the technology of half-cut cells and multi-layer metallization (**half-cut + MBB**), the panel is better able to withstand micro-cracks and maintains high efficiency even with partial shading. Additionally, **good performance in high temperatures and low sunlight** helps maintain production in variable weather conditions typical of Poland. This is the choice for investors and EPC companies who want to combine high power density with the durability of glass-glass construction and lower operational risks. ## Notable figures - At 22.3% efficiency, this panel is on par with typical \*\*TOPCon 550-600W\*\* modules - At 222.6 W/m² power density, roof space requirements are typical for \*\*TOPCon 550-600W\*\* panels - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 550-600W\*\* panels - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces - In the top 40% for efficiency among all TOPCon panels ## Questions ### How does N-type TOPCon technology in the Solarspace Lumina II differ from standard PERC cells? N-type TOPCon cells used in the Lumina II SS8-72HD feature a tunnel oxide passivation layer that substantially reduces charge carrier recombination. This results in lower initial degradation (LID/LETID) compared to conventional PERC modules and a higher long-term energy yield. For project owners, this translates to more predictable financial returns and a better LCOE profile over the 30-year operational lifetime. ### What warranty does the Solarspace Lumina II SS8-72HD 565-585N carry? The Lumina II SS8-72HD series comes with a 12-year product warranty covering material and workmanship defects, and a 30-year linear power warranty. Solarspace guarantees at least 87.4% of nominal output after 30 years, with a linear annual degradation rate of 0.45%. This is among the stronger power warranty commitments available for modules in this performance class. ### Is the Solarspace Lumina II SS8-72HD suitable for utility-scale solar farms and carports? Yes. The Lumina II SS8-72HD was designed primarily for large ground-mounted installations, utility-scale solar farms, and carports. Its bifacial dual-glass construction captures reflected irradiance from the ground, boosting energy yield by several percentage points depending on surface albedo. The glass-glass structure also provides superior mechanical strength and moisture resistance compared to glass-backsheet modules, making it well-suited for long-term outdoor exposure. ### What are the dimensions and weight of the Solarspace Lumina II SS8-72HD 585N panel? The Solarspace Lumina II SS8-72HD measures 2278×1134×30 mm and weighs approximately 31.5 kg. This is a large-format module typical for the 565–585 Wp power class. The weight of the dual-glass construction requires appropriate racking, lifting equipment, and structural verification of the roof or ground-mount foundation before procurement. ### How does the Solarspace Lumina II SS8-72HD perform in high temperatures and low-irradiance conditions? The Lumina II SS8-72HD has a power temperature coefficient of -0.29%/°C, meaning it loses less output per degree of temperature rise than most PERC-based modules. The half-cut cell layout combined with multi-busbar (MBB) metallization also improves performance under partial shading and diffuse irradiance. These characteristics are particularly valuable in Central European climates where full-sun hours are limited and variable weather is common. ### Is Solarspace a Tier 1 manufacturer, and does it matter for large-scale installations? Yes, Solarspace is listed as a Tier 1 manufacturer by Bloomberg NEF. This means its modules are accepted by banks and financial institutions funding PV projects without requiring additional guarantees. For investors and EPC contractors planning utility-scale farms or installations that require project financing, Tier 1 status is a practical prerequisite when applying for loans or leasing agreements. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ss8-72hd-565-585-n-30-us-converted-a9e7ea85aa40.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.5 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +2.3 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, lighter, +2.1 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | -35 W, lighter, +2.1 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | -35 W, lighter, +2.1 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | -30 W, lighter, +2.0 pp | | [AIKO AIKO-A625-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a625-mah72dw) | 625 W | +50 W, cooler, +1.9 pp | | [Solarspace SS8-72HD-535M](https://comparepv.com/panel/solarspace-ss8-72hd-535m) | 535 W | -40 W, hotter, -1.6 pp | | [Solarspace SS8-72HD-540M](https://comparepv.com/panel/solarspace-ss8-72hd-540m) | 540 W | -35 W, hotter, -1.4 pp | | [Solarspace SS8-72HD-545M](https://comparepv.com/panel/solarspace-ss8-72hd-545m) | 545 W | -30 W, hotter, -1.2 pp | | [Solarspace SS8-72HD-550M](https://comparepv.com/panel/solarspace-ss8-72hd-550m) | 550 W | -25 W, hotter, -1.0 pp | | [Solarspace SS8-72HD-555M](https://comparepv.com/panel/solarspace-ss8-72hd-555m) | 555 W | -20 W, hotter, -0.8 pp | | [Solarspace SS8-72HD-560M](https://comparepv.com/panel/solarspace-ss8-72hd-560m) | 560 W | -15 W, hotter, -0.6 pp | | [Solarspace SS8-72HD-565N](https://comparepv.com/panel/solarspace-ss8-72hd-565n) | 565 W | -10 W, -0.4 pp | | [Solarspace SS8-72HD-570N](https://comparepv.com/panel/solarspace-ss8-72hd-570n) | 570 W | Very close match | | [Solarspace SS8-72HD-580N](https://comparepv.com/panel/solarspace-ss8-72hd-580n) | 580 W | Very close match | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +75 W, lighter, +2.9 pp | --- Source: https://comparepv.com/panel/solarspace-ss8-72hd-575n 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.
