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!

Double Assurance, Worry-Free Shopping

After-sales support + 25-year performance guarantee! Official assurance that power output will not drop below 81.75% within 25 years! For any product or service issues during use, contact customer service anytime, and we will follow up to solve it completely, making your purchase and use worry-free!

Q&A What does "12V" mean in the product title? Why is it different from the panel's actual voltage?

"12V" indicates that the solar panel is designed for 12V battery systems. To ensure proper and efficient charging, the panel's actual output voltage—such as open‑circuit voltage (VOC) and maximum power voltage (VMP)—is intentionally higher than 12V.

Should I connect solar panels in series or in parallel?

• Series connection: Increases total system voltage while current remains the same as a single panel.
• Parallel connection: Increases total current while voltage remains the same as one panel.

Choose the connection method based on your system's voltage requirements and current capacity.

What components are required for an off‑grid solar power system?

A complete off‑grid system typically includes:

• A solar panel
• A charge controller to regulate power
• A battery for energy storage
• Adapter cables to connect the panel to the controller
• Battery cables to connect the controller to the battery

What if the solar panel arrives scratched or defective?

If your panel arrives damaged or defective, please take clear photos immediately and contact our support team. We'll respond promptly and help resolve the issue as quickly as possible.
