Show series description

The Sunpro SPDG(640/665)-BC132R12 series is a breakthrough bifacial glass-glass solution that combines powerful rated power with exceptional durability in harsh environmental conditions. The use of advanced large-format cell technology allows for generating significant energy yields while optimizing the structural costs of the entire installation. A key differentiator of this series is its bifacial module activity, enabling energy harvesting from light reflected off the ground, which directly translates into higher investment profitability compared to standard single-sided panels. The double-glass construction guarantees maximum resistance to PID degradation and micro-cracks, effectively eliminating typical system longevity issues in the demanding Polish climate. These panels are designed for professional photovoltaic farms and modern industrial facilities, where the key factor is maximizing yield from the available area. Thanks to low temperature coefficients, the devices maintain very high efficiency even during intense sunlight and summer heat. Choosing this series is a guarantee of stable energy production for decades, clearly distinguishing it from less durable solutions available on the market. It is an ideal proposition for investors focusing on high-performance N-type technology and long-term capital security.

Panels from the same series differ mainly in power output while having identical dimensions. Learn why →
