The Sunpro SPDG (485/500W)-N120R10 series utilizes N-type TOPCon cell technology, which redefines performance standards in modern photovoltaic installations. A key differentiator of these modules is the use of rectangular cells, allowing for maximum utilization of the panel surface and achieving higher power density while maintaining compact dimensions. The advanced bifacial double glass design ensures the panels generate energy from both sides, which is particularly beneficial in installations with a high albedo coefficient, such as roofs covered with a light membrane or ground-mounted systems. Thanks to the elimination of LID and a low temperature coefficient, this series guarantees stable power production even on hot days and in low sunlight. Choosing these modules solves the problem of limited installation space, offering higher resistance to micro-cracks and extreme weather conditions. This solution is dedicated to investors seeking maximum return on investment in the commercial and industrial sectors, where technical quality and long-term reliability are essential. Sunpro stands out from the competition with minimal linear degradation, which translates into real profits throughout the power plant's life cycle. The double tempered glass used further enhances fire safety, making this series one of the safest choices currently available on the Polish market.

Common questions

6 answered

How does the Sunpro SPDG N-type TOPCon series differ from standard P-type PERC panels?

The N-type TOPCon cells used in the SPDG series have a lower degradation rate and better high-temperature response than conventional PERC cells. This means the panel loses less power on hot days and in its first year of operation, with a more stable output decline in subsequent years. In practice, this results in higher real energy yield over the full 30-year power warranty period.

Are the Sunpro SPDG (485/500W)-N120R10 panels suitable for ground-mount installations and flat roofs with light-colored surfaces?

Yes, this is one of the best applications for this series thanks to its bifacial double-glass construction. The panels generate additional energy on the rear side by capturing light reflected from the ground. Ground-mount systems and flat roofs covered with a light roofing membrane (high albedo coefficient) can achieve several to over a dozen percent additional output compared to a standard monofacial panel.

What warranty comes with the Sunpro SPDG N120R10 panels and what does it cover?

The manufacturer provides a 25-year product warranty and a 30-year linear power output warranty. The product warranty covers material and workmanship defects, while the power warranty guarantees a defined minimum percentage of nominal output over the years of operation. This is one of the longer coverage periods currently available on the solar module market.

Do the Sunpro SPDG panels perform well in low temperatures and low irradiance conditions?

Yes, the TOPCon technology used in this series features a low temperature coefficient of power, meaning a smaller output drop as operating temperature rises. Additionally, N-type cells respond well to diffuse and weaker light, allowing the panels to produce energy efficiently on cloudy days and in cooler climates.

Is Sunpro a Tier 1 manufacturer, and is it worth investing in Chinese-made panels for a commercial installation?

Sunpro Power holds Tier 1 manufacturer status, confirming financial stability and production compliance with rigorous quality standards. For commercial and industrial installations, this means lower risk regarding long-term warranty servicing. Large-scale Chinese manufacturing also keeps the price competitive while maintaining certified technical parameters.

What protection against mechanical damage and fire does the SPDG N120R10 series offer?

The panels use double tempered glass on both sides of the module, significantly increasing resistance to cell microcracks, hail, and mechanical loads compared to a standard backsheet construction. Double glass also has a better fire resistance class, making this series one of the safer choices for public buildings and industrial facilities.
