The Sunpro TOPCon 182 BIFACIAL series is an advanced solution based on N-type cells that redefines performance standards in the variable Polish climate. Thanks to the use of bifacial (double-sided) technology, these panels generate additional energy from radiation reflected from the ground, which significantly increases the total yield from every square meter of the installation. The use of 182-millimeter silicon wafers in combination with modern TOPCon architecture allows for achieving higher efficiency in low light, which is crucial in Polish conditions during autumn-winter periods. This solution effectively minimizes the problem of light-induced degradation, offering parameter stability for many years of intensive use. These modules are an ideal choice for professional investors focused on maximizing profits from photovoltaic farms and large commercial ground-mounted systems. Unlike standard older-generation cells, this series is characterized by a lower temperature coefficient, which directly translates to smaller energy losses during summer heatwaves. The innovative double-glass design provides exceptional resistance to extreme weather conditions and micro-cracks, which clearly distinguishes this product from the competition. It is a substantive response to the needs of a market seeking to optimize the Levelized Cost of Energy (LCOE) while maintaining the highest standards of durability.

Common questions

6 answered
How much extra power does bifacial technology add in Sunpro TOPCon 182 panels?
The bifacial modules in the TOPCon 182 BIFACIAL series generate additional current from the rear side thanks to light reflected off the ground. In practice, with a high-albedo surface such as white gravel or reflective film, and ground-mount installation, energy yield can increase by 5-15% compared to a standard monofacial panel of the same 600 Wp nominal power.
What warranty do Sunpro TOPCon 182 BIFACIAL panels come with?
The manufacturer offers a 25-year product warranty covering material and workmanship defects, plus a 30-year power performance warranty. This means the module should still deliver a significant share of its original output after that period, providing solid protection for investments in commercial installations and utility-scale PV farms.
Are TOPCon 182 BIFACIAL panels suitable for ground-mounted PV farms?
Yes, the double-glass construction combined with bifacial technology makes this series a strong choice for large ground-mount and commercial installations. Panels elevated above the ground capture reflected light on both sides, which, given adequate terrain albedo, meaningfully increases energy output per square meter compared to sloped-roof mounting.
Do Sunpro TOPCon 182 panels perform well in Polish winter conditions?
Yes, N-type TOPCon cells deliver higher efficiency in low-light conditions, which matters during Polish autumn and winter when solar irradiance is limited. Additionally, the low temperature coefficient benefits performance in summer as well, reducing power losses when module temperatures rise.
How does TOPCon technology differ from older PERC cells in this series?
TOPCon (Tunnel Oxide Passivated Contact) uses N-type cells with an additional passivation layer that reduces recombination losses and light-induced degradation (LID), common in older P-type PERC cells. The result is higher initial efficiency, better low-light performance, and more stable power output over many years of operation.
Is the double-glass construction in TOPCon 182 BIFACIAL panels more durable than a standard panel?
Yes, using two layers of glass instead of glass and a rear backsheet significantly improves resistance to microcracks, moisture ingress, and extreme weather such as hail or large temperature swings. This build quality extends module lifespan and supports the long-term 30-year power warranty.
