The SpolarPV SPV495-TM10-120 panel series is an advanced solution utilizing N-type TOPCon cell technology, which allows for exceptional efficiency exceeding 22.8%. Thanks to the use of M10 size silicon wafers and a Half-Cut construction, these modules offer higher power output while maintaining optimal dimensions, making them an ideal choice for the roofs of single-family homes as well as commercial installations. A key benefit for the investor is the low temperature coefficient of power, which guarantees stable operation and high energy yields even on hot, summer days. These panels effectively solve the problem of performance drops in low-sunlight conditions, offering excellent sensitivity to diffused light, which in the Polish climate translates to a real increase in annual energy production. What sets them apart from the competition is their high resistance to the PID effect and a reinforced mechanical design, certified to withstand extreme snow and wind loads. By choosing this series, the user receives a product with an extended power warranty, minimal linear degradation, and a modern design that combines aesthetics with the highest technical parameters currently available on the market. It is a reliable link in the energy system that maximizes the profitability of every green energy investment.

Common questions

6 answered
What warranty does the SpolarPV SPV495-TM10-120 come with and what does it cover?
The SPV495-TM10-120 series comes with a 12-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. This means the manufacturer guarantees minimum performance according to a defined degradation schedule for three decades. It is one of the longer warranty packages available in this price class and has a direct positive impact on the overall return on investment.
What is TOPCon technology and why is the SPV495-TM10-120 better than older PERC panels?
TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell architecture with an additional passivation layer that reduces carrier recombination. In practice this means efficiency exceeding 22.8% versus the typical 20-21% for PERC, a lower temperature coefficient, and slower long-term degradation. The SPV495-TM10-120 series leverages these advantages to generate more energy from the same roof area over the entire system lifetime.
Do the SpolarPV SPV495-TM10-120 panels perform well on overcast days common in Central European climates?
Yes. N-type TOPCon cells exhibit excellent sensitivity to diffuse and low-irradiance light, which is especially important in climates with a high proportion of cloudy days. The SPV495-TM10-120 continues to generate power efficiently on overcast mornings and during autumn months, delivering measurably higher annual energy yield compared to older-generation panels in real-world conditions.
Is the SPV495-TM10-120 at 495 Wp suitable for a residential rooftop, or is it too large a module?
The SPV495-TM10-120 series is designed for both residential rooftop installations and commercial projects. Using M10 silicon wafers combined with a half-cut cell layout allows the module to reach 495 Wp while maintaining practical dimensions. Before purchasing, it is recommended to verify roof load capacity and available roof area with your installer, particularly on smaller roof sections.
How do the SPV495-TM10-120 panels perform in summer heat at high temperatures?
N-type TOPCon cells have a lower power temperature coefficient than standard PERC modules. This means the SPV495-TM10-120 loses a smaller percentage of rated power as temperatures rise. On hot summer days when other modules can drop by more than 10% in output, this series maintains more stable production, resulting in higher energy yields precisely during the peak solar season.
Is the SpolarPV SPV495-TM10-120 resistant to PID, high wind loads, and heavy snow loads?
Yes. The SPV495-TM10-120 series features high resistance to PID (Potential Induced Degradation), which can reduce module efficiency in high-voltage string systems. The modules also have a reinforced mechanical structure certified to withstand extreme snow and wind loads, which is important in regions prone to heavy snowfall or strong gusts, ensuring reliable long-term operation under demanding environmental conditions.
