DEG Solar engineers and manufactures crystalline silicon photovoltaic modules from 390 W to 550 W, delivering reliable yield for residential, commercial and utility-scale installations worldwide.
From compact residential rooftops to multi-megawatt ground mounts, our monocrystalline modules are tuned for the power class and balance-of-system that fit your project.
Every module leaves our Suzhou facility after in-line electroluminescence and flash testing. We design for low degradation, high irradiance tolerance and long-term bankability.
Up to 21.3% module efficiency with tight positive power tolerance of 0 to +5 W.
Pmax coefficient of −0.35 %/°C keeps output strong in hot climates and rooftop heat.
Guaranteed annual degradation below 0.55%, with at least 84.8% power retention at year 25.
3.2 mm tempered glass, IP68 junction box, MC4 connectors and −40 °C to 85 °C operating range.
Whether your project sits on a suburban rooftop, a warehouse, a solar park or a remote off-grid site, DEG modules are specified and supported for the job.
Lightweight M6 modules optimized for pitched roofs, with clean aesthetics and simple installation.
High-density M10 arrays for warehouses, factories and carports that offset daytime load.
550 W high-power modules on 1500 V systems reduce BOS cost and LCOE for large parks.
Rugged modules paired with storage for telecom, agriculture and remote power systems.
Our modules pass accelerated lifetime testing beyond certification minimums, so your asset keeps producing year after year.
Guaranteed maximum power loss per year across the warranty period.
Minimum retained output under the linear performance warranty.
Mechanical load certified for high wind and snow environments.
Every module undergoes electroluminescence and flash testing before shipment.
