The Sunpro 182 TOPCon BIFACIAL series is an advanced solution based on N-type cells that redefine performance standards in modern photovoltaics. The key differentiator of this line is bifacial power generation technology, which allows for harvesting additional energy from reflected radiation, significantly increasing the profitability of ground-mounted investments. Thanks to the use of 182 mm wafers, these modules offer optimal electrical parameters while maintaining high power density. The use of TOPCon cells effectively minimizes light-induced and voltage-induced degradation phenomena, guaranteeing stable production for decades. This series solves the problem of limited space by providing more energy per square meter than standard monofacial modules. For users, the low temperature coefficient is key, ensuring high efficiency even on hot days when traditional panels lose effectiveness. The product is dedicated to professional solar farms and large industrial facilities where the lowest levelized cost of energy matters. What sets it apart from competing solutions is the reinforced glass-glass construction, which provides extreme resistance to corrosive factors and harsh weather conditions, forming a solid foundation for any renewable energy project.

Common questions

6 answered
How much extra energy does bifacial technology add in Sunpro 182 TOPCon BIFACIAL panels?
By generating power from both the front and rear side, bifacial modules can yield anywhere from a few percent up to around twenty percent more energy compared to standard monofacial panels. The actual gain depends on ground albedo (e.g. light gravel, white roofing membrane) and mounting height above ground. Best results are achieved in ground-mounted installations on light-colored surfaces, which is why this series is particularly recommended for solar farms.
What warranty comes with Sunpro 182 TOPCon BIFACIAL panels?
Sunpro Power provides a 25-year product warranty along with a 30-year linear power output warranty. This means the module maintains a guaranteed power production level for three decades, while material and manufacturing defects are covered for a quarter century. This is one of the longer warranty periods currently available on the PV market.
How does TOPCon cell technology differ from PERC in Sunpro 182 panels?
TOPCon cells use an additional tunnel oxide layer that reduces charge carrier recombination, enabling higher efficiency than conventional PERC cells. In practice, this means higher power output from the same module area, a lower temperature coefficient, and reduced light- and voltage-induced degradation. For the customer, this translates into more stable energy production throughout the system's entire service life.
Are Sunpro 182 TOPCon BIFACIAL panels suitable for large-scale solar farms?
Yes, this series is designed primarily for professional solar farms and large industrial installations. The glass-glass construction provides high resistance to harsh weather and corrosion, while power output up to 480 Wp combined with bifacial technology helps achieve a lower levelized cost of energy (LCOE) than standard monofacial modules on the same ground footprint.
How do Sunpro 182 TOPCon BIFACIAL panels perform in high summer temperatures?
Thanks to the low temperature coefficient typical of N-type TOPCon cells, this series loses less power output on hot days than traditional PERC or polycrystalline panels. This matters especially for ground-mounted installations and large farms in warmer regions, where panel temperature can significantly exceed ambient temperature, affecting daily energy yield.
Does the glass-glass construction of Sunpro 182 panels require special mounting equipment?
Glass-glass panels are somewhat heavier than modules with a standard backsheet, so this should be factored into the choice of mounting structure, especially for large ground-mounted installations. The technology itself doesn't require non-standard mounting hardware, but it does provide higher mechanical resistance and better sealing, resulting in longer module lifespan under harsh weather conditions.
