About the DMEG TopCon N-Type
The DMEG TopCon N-Type is our specification for larger roof arrays where excellent efficiency and strong value at scale are the priority. DMEG's N-type TOPCon panels deliver 22.1% peak efficiency across a 420–445W power range, offering a significant step up from standard PERC technology. TOPCon (Tunnel Oxide Passivated Contact) technology eliminates the light-induced degradation seen in older PERC panels and delivers a lower temperature coefficient — maintaining higher output throughout the panel's lifetime. DMEG's rigorous manufacturing standards and strong UK distribution network make these panels a reliable, long-term choice for Yorkshire homeowners.
Key Features
N-type TOPCon Technology
Tunnel Oxide Passivated Contact cells eliminate light-induced degradation, maintaining higher efficiency throughout the panel's 25+ year lifespan compared to P-type PERC alternatives.
22.1% Peak Efficiency
Significantly more efficient than standard PERC panels — generates more power per square metre and makes larger systems more productive without increasing roof footprint.
Lower Long-Term Degradation
N-type cells degrade at approximately 0.4% per year versus 0.5–0.6% for standard PERC panels — more electricity generated over the system's lifetime.
Excellent Temperature Performance
−0.30% per °C temperature coefficient means the DMEG TopCon loses less power on warm days than PERC panels, maintaining consistent output across the seasons.
Optimised for Large Arrays
Cost-efficiency at volume makes these panels the smart choice for 12+ panel systems — delivering high efficiency across the full roof for maximum generation and ROI.
MCS Eligible
Fully certified for MCS installations, Smart Export Guarantee registration, and all UK grid connection requirements.
Why Premier Electrical installs this product
For larger installations on good roof space, the DMEG TopCon N-Type provides outstanding value. N-type cells degrade more slowly than PERC alternatives and the 25-year performance warranty reflects this superior long-term stability. When installing across a full roof — 12 panels or more — the combination of 22.1% efficiency and competitive pricing means customers get maximum output without overpaying. DMEG's UK distribution and warranty support infrastructure give us confidence in specifying these panels for Yorkshire homes that will rely on them for 25+ years.
