Solar panels determine the cost of the project and the efficiency of the system for decades.
We recommend DMEGC panels to our clients, this is one of the five leading manufacturers in the world, which supplies solutions to over 80 countries. In this article, we will analyze how N-type panels differ from P-type and which ones are more profitable to take.
Advantages of TOPCon N-type panels
Company DMEGC produces modules based on modern N-type TOPCon technology. This is a new generation of solar panels that significantly outperforms the classic P-type:
- Higher efficiency: up to 23.2% versus 19–21% for P-type. This means more electricity from the same area of roof or land.
- Power stability: P-type panels lose 1–3% of their performance in the first year. This is due to the interaction of boron with oxygen in the first year of operation. N-type DMEGC panels do not contain boron, maintaining stable power from day one.
- Work better in the heat: when heated to 60°C in the summer, losses are only ~10%, while in the P-type - up to 17.5%.
- Two-sided generation: the panels produce energy from both the front and back sides. On snow or light soil, this gives up to +30% additional generation.
- Durability: degradation ≤0.4%/year. After 30 years, the panels retain over 87% of their capacity.
Why is this important in Ukraine?
- Hot summer: in our conditions, the temperature of the elements easily rises to 50–70°C. DMEGC panels lose less power than conventional ones.
- Winter and snow: thanks to the double-sidedness, you can get more generation on snow-covered surfaces.
- Frequent cloudy days: panels work better in low light - morning, evening, cloudy weather.
- Hard climate: double glazing withstands loads of up to 8100 Pa (snow) and 4000 Pa (wind).
DMEGC Panels Guarantees and Certification
- Linear Warranty: 30 years. Guarantees ≥87.4–89.4% capacity after 30 years, with ≤0.4%/year degradation after the first year. DMEGC offers one of the best warranties in the industry, compared to 10–12 years of product guarantees from competitors.
- Product warranty: 15–25 years depending on model. Covers manufacturing defects: problems with glass, frame or junction box.
- They have certificates: TÜV Rheinland, PVEL Top Performer, ISO, low-carbon certification. All this confirms the quality.
- Have a consistently high reputation: Tier-1 in the Bloomberg rating, Top Brand PV Modules award from EUPD Research for 6 consecutive years.
N-type panels are more expensive, but pay for themselves faster due to their greater efficiency and durability.
