25% High-Efficiency Power Generation Core

50W N-type A+ grade solar cells, reinforced with 16 fully welded busbars, achieving a power generation efficiency of up to 25%! The A+ grade monocrystalline silicon material significantly reduces the risk of microcracks, and with 16 silver-containing busbars, the degradation rate is extremely low (only 2% in the first year, 0.55% annually on average), ensuring longer lifespan and more reliable power generation benefits!

Durable MC4 Connectors

Standard MC4 interface with built-in galvanized copper pins + enlarged PPO housing, offering better current carrying capacity than aluminum pin versions and more stable performance! The sturdy PPO housing is highly compatible, easily matching other connectors of the same specifications, making installation hassle-free!

IP68 Waterproof Junction Box

Uses professional potting technology to strictly prevent water vapor/steam from entering internal circuits, eliminating short-circuit risks at the source, and effectively inhibiting rust and corrosion! Excellent thermal conductivity rapidly dissipates heat, further extending component life.

High-Strength Aluminum Alloy Frame

Stronger than steel frames! Long-lasting and bright without fading, fully rust and corrosion-resistant; additional frame sealant effectively isolates monocrystalline cells from air corrosion; pre-drilled design simplifies installation, allowing easy DIY setup!
