Sunpro TOPCon 210R BIFACIAL panels are an advanced solution based on rectangular N-type cells, which redefine efficiency standards in utility-scale and commercial installations. The use of TOPCon technology allows for a significant reduction in recombination losses, resulting in higher efficiency even in challenging lighting conditions and under heavy cloud cover. A key feature of this series is its bifacial double-sided design, enabling the generation of additional energy from radiation reflected off the ground, which is particularly effective on ground-mounted farms and roofs covered with bright membranes. Thanks to the use of the innovative 210R format, these modules offer an optimal power-to-area ratio, effectively solving the problem of limited mounting space while reducing structure and cabling costs. This series eliminates the risk of LID and LeTID effects, guaranteeing minimal annual degradation and exceptional yield stability over years of operation. Compared to competing solutions, Sunpro TOPCon 210R BIFACIAL provides a better temperature coefficient, making them an ideal choice for investors seeking maximum return on capital in the Polish climate. This is professional equipment dedicated to photovoltaic farms and industrial facilities focusing on the highest durability and maximum reduction of LCOE cost thanks to high power density.

Common questions

6 answered
What is the maximum power output of Sunpro TOPCon 210R BIFACIAL panels?
Modules in this series reach up to 635 Wp of maximum power. This is achieved through N-type TOPCon cell technology in the 210R format combined with a bifacial double-sided design, which further increases energy yield by generating current from the rear side of the panel. Thanks to the high power density per square meter, these panels are particularly well suited for utility-scale projects where optimal use of available space matters.
How does a bifacial panel differ from a standard monofacial panel?
A bifacial panel, unlike a standard monofacial module, generates energy from both the front and rear sides. The Sunpro TOPCon 210R BIFACIAL captures reflected radiation from the ground surface, which is especially effective on ground-mounted farms with light-colored terrain or gravel, as well as on roofs covered with white membrane. In practice this translates into an additional energy gain of a few up to over ten percent compared to a single-sided module of the same nominal power.
What warranty comes with Sunpro TOPCon 210R BIFACIAL panels?
Sunpro Power provides a 25-year product warranty along with a 30-year power output warranty. This means that over three decades of operation, minimal annual degradation is guaranteed, and the module itself is covered against material and manufacturing defects. This is a significant factor for investors planning PV farms with a long-term return-on-investment horizon.
What is TOPCon technology and is it worth choosing panels built with it?
TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology that reduces recombination losses through an additional passivation layer on the rear side of the cell. In practice this results in higher efficiency, better performance under low and diffuse light conditions, and lower annual degradation compared to older PERC-based technologies. For investors, this means higher and more stable energy yield throughout the entire lifetime of the installation.
Do Sunpro TOPCon 210R BIFACIAL panels perform well in high summer temperatures?
Yes, this series features a favorable temperature coefficient, resulting in a smaller power drop at high operating temperatures compared to competing modules based on older technologies. This is especially important in summer, when cell temperature can significantly exceed STC conditions, and stable performance translates into higher real-world energy yield throughout the season.
What type of installations are Sunpro TOPCon 210R BIFACIAL panels best suited for?
Due to their high unit power, 210R format, and bifacial design, this series is primarily dedicated to solar farms and industrial or commercial sites where minimizing LCOE is the priority. High power density reduces the number of modules needed as well as mounting structure and cabling costs, which is especially significant for utility-scale installations.
