Premium 425W Half Cell Mono Solar Panels for Domestic Home Power Systems

Built with advanced TOPCon N-type monocrystalline cells, delivering superior performance and lower degradation compared to conventional P-type modules.

Maximum module efficiency reaches 22.5%, maximizing energy yield per square meter and reducing overall system BOS costs.

Seven power grades available (410W to 440W), providing flexible options to match diverse project requirements and optimize array design.

First-year power degradation is below 2%, and annual degradation from year 2 to 30 is below 0.55%, ensuring long-term energy yield and return on investment.

Every module delivers at least its rated power with no negative tolerance, giving customers more energy and greater system predictability.

Withstands 5400Pa front / 2400Pa back snow and wind loads, and operates reliably from -40C to +85C, making it suitable for harsh outdoor environments.

Compatible with 1500Vdc (IEC/UL) systems to reduce string costs and line losses; IP68-rated junction box and connectors ensure long-term waterproof and dustproof performance.

Pmax temperature coefficient of just -0.290%/C, ensuring stable power generation even in high-temperature environments.
