TOPcon photovoltaic module i-TopCon

bifacialIEC 61730IEC 61215

Overview
Benefit from outstanding output with the DMEGC 500Wc Bifacial N‑Type solar panel, engineered to maximize power generation in varied conditions. Using bifacial N‑Type TOPCon technology, it captures direct and reflected light to increase energy yield on the same footprint while ensuring long-term durability. Glass‑glass design, 22.6% efficiency and low degradation for sustained performance.

Key features

• Manufacturer warranty 25 years, production guarantee 30 years
• Reliability validated by TÜV and PID tests
• Bifacial N‑Type TOPCon technology: higher efficiency
• 2 mm double glass: extreme weather resistance

How the DMEGC 500Wc Bifacial N‑Type panel works

• N‑Type TOPCon cells capture sunlight on both faces of the panel.
• The front face absorbs direct irradiance while the rear face harvests light reflected from the ground or roof.
• Solar energy is converted into high-quality direct current.
• This DC is then converted to 230 V by the inverter to power household appliances.
• The 2 mm double glazing stabilizes temperature and protects cells from shocks and weather.
• Production monitoring is available in real time via a connected interface (GX, VRM, or dedicated app).
• You consume your solar electricity directly and reduce grid expenses.

Benefits

• High efficiency: maximized output even in low irradiance.
• Bifacial design: production increase up to 30% depending on mounting and ground reflectivity.
• 2 mm toughened glass on both sides: long-term protection against corrosion, humidity and thermal variations.
• 30 mm black anodized frame for aesthetic integration on residential roofs.
• Very low annual degradation, retaining 87.4% power after 30 years.

Tests and certifications

• Inspections by independent TÜV Rheinland and TÜV SÜD laboratories.
• Standards: IEC 61215, IEC 61730, IEC 61701 (salt mist), IEC 62716 (ammonia), IEC TS 62804, IEC TS 63342, IEC 60068.
• Humidity‑freeze cycles, mechanical load and extreme heat tests simulating over 30 years of exposure.
• 4★ "zero carbon" rating by TÜV SÜD and carbon footprint PPE2 below 550 kg CO₂e/kWc.
• Tier 1 by Bloomberg and awarded "Top Brand PV" by EUPD Research.

Compatible equipment

• Compatible with microinverters APS, Enphase, Hoymiles.
• Compatible with hybrid inverters Sofar, Victron, Growatt.
• Suitable for mounting: tiled roofs, corrugated steel, flat roofs, pergolas, carports.
• Connectable to residential or professional supervision (GX, VRM, energy routers).
