Solar panel Solarspace Lumina II 590W | N-Topcon Bifacial double glass

Solarspace Lumina II 590W: Power N-Topcon of last generation

The SS8-72HD series of Solarspace represents the vanguard of photovoltaic technology. By combining N-TYPE cells with the Topcon architecture, this 144-cell panel (Half-Cell) offers a significantly higher performance than conventional PERC modules, especially in high temperature and low light environments.

1. Bifacial Technology: Double starting performance

The Solarspace Lumina II not only generates energy with its front face. Its bifacial design allows the back face to collect the reflected light of the soil or nearby surfaces.

• Extra gain: Depending on the albedo of the mounting surface, this panel can increase its production up to a 25% additional, which optimizes the return of investment (ROI) by reducing the costs of structure and wiring (BOS).

2. N-Topcon cells: Efficiency and stability

N-Topcon cells (Tunnel Oxide Passivated Contact) offer critical advantages over traditional technology:

• Minimum degradation: Being type N, they are immune to the LID effect (light-induced degradation). The loss of power the first year is less than 1%, guaranteeing unattainable long-term stability for other modules.

• Luminum response: Its excellent faint light response allows you to capture energy during the first and last hours of the day, as well as on cloudy days, extending the daily generation window.

3. Durability reinforced with double glass

The "Dual Glass" configuration (2.0 mm glass on both sides) offers an industrial grade protection:

• Corrosion resistance: Certificate against Salina and Ammonia Fog (IEC 61701 and IEC 62716), which makes it ideal for agricultural ships, coastal areas and industrial facilities.

• Class A protection: Its glass structure reduces the risk of fire compared to plastic backsheet panels (backsheet).

• Mechanical load: Designed to support extreme snow pressures (5400 Pa) and wind (2400 Pa), guaranteeing the structural integrity of the module for decades.

4. Optimized temperature coefficient

With a coefficient of -0.300% / ° C. (and up to -0.290% in some variants), this panel stands out for its ability to maintain high production in warm climates. While other panels reduce its power drastically with heat, Lumina II continues to operate with stable efficiency.

Frequently Asked Questions (FAQ)

1. Is the use of 590W panels profitable in residential facilities? Due to its size (2.27 meters long) and high power, they are recommended mainly for industrial buildings or floor facilities. However, if the residential roof has enough space, it is an excellent way to reduce the number of panels and supports necessary.
2. How much more does it produce because bifacial? In a floor installation with clear gravel or a blank painted cover, the gain can be 10% to 20% per year. In dark roofs, the gain is lower, but the panel is still superior for its N-Topcon technology.
3. What maintenance does the double glass need? The same as a standard panel (cleaning with water). The advantage is that the double glass is much more resistant to abrasion of dust and sand, maintaining the transparency of the frontal glass for much longer.
