The SERIES N 5 photovoltaic panels are an advanced solution based on innovative N-type TOPCon technology, which sets new efficiency standards in the Polish climate. This series stands out primarily due to its minimal light-induced degradation effect, which guarantees stable energy production for decades. Thanks to the use of bifaciality in selected models, these modules effectively recover energy reflected from the ground, making them an ideal choice for modern solar farms and flat roofs. Using N-type TOPCon technology allows for significantly better yields in low sunlight, which effectively solves the problem of lower efficiency on cloudy days. The specific cell design also provides exceptional resistance to high temperatures, effectively limiting power drops during summer heat. Products from this line offer the highest module efficiency enclosed in a durable form, attracting investors looking for uncompromising durability. Compared to traditional P-type solutions, SERIES N 5 offers a significantly longer linear warranty on power output, which directly translates into a faster return on investment. This solution is dedicated to conscious prosumers and companies that focus on maximizing yields from a limited installation area.

Common questions

6 answered
What is the warranty on Sunlike Solar SERIES N 5 panels?
Sunlike Solar SERIES N 5 panels come with a 20-year product warranty and a 30-year linear power output warranty. This means the manufacturer guarantees a defined power retention level for three full decades. Compared to standard P-type modules typically covered by a 25-year power warranty, SERIES N 5 provides an additional 5 years of investment security.
Do Sunlike Solar SERIES N 5 panels perform well on cloudy days?
Yes, the N-type TOPCon cell technology in SERIES N 5 delivers better low-light performance than standard P-type modules. A lower temperature coefficient and minimal LID (Light Induced Degradation) effect mean these panels generate energy more efficiently under overcast skies — a key advantage in Poland's variable climate with many cloudy days throughout the year.
How does the SERIES N 5 compare to standard P-type PERC panels?
SERIES N 5 uses N-type TOPCon cells instead of conventional P-type PERC technology, resulting in higher module efficiency, significantly reduced LID, and better high-temperature performance. In practice, this translates to a higher annual energy yield from the same roof area and a faster LCOE payback over the full 30-year power warranty period.
What is the maximum power output of Sunlike Solar SERIES N 5, and how many panels do I need for a home?
The top model in the SERIES N 5 lineup reaches up to 640 Wp. This is a high-power module designed primarily for commercial and utility-scale PV installations. A typical 10 kWp residential system would require only 16 panels. The high per-panel wattage reduces the total module count, mounting labor costs, and roof space required.
Are SERIES N 5 panels suitable for flat roofs or ground-mounted systems?
Yes, SERIES N 5 performs excellently in ground-mounted and flat-roof installations. The series is monofacial rather than bifacial, but its TOPCon technology delivers high efficiency when modules are tilted at an optimal angle. Flat roofs and ground arrays allow precise tilt adjustment, maximizing annual energy yield from each panel rated up to 640 Wp.
How does the SERIES N 5 handle high summer temperatures?
The N-type TOPCon cells in SERIES N 5 feature a low temperature power coefficient, meaning proportionally smaller output losses during summer heat compared to standard P-type panels. When module temperature exceeds the 25°C STC reference point, SERIES N 5 loses less power, delivering better real-world yield on hot, sunny days.
