200W 400W Watt 18V/36V Solar Panel N-Type 18BB 25% IP68 PV Home RV power

Product Features

(25% High-Efficiency)

200W N-type A+ grade solar cells, reinforced with 18 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 18 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!

FAQ🔌 What is the difference between off-grid and on-grid systems?
Off-grid solar systems operate independently from the utility grid and rely on battery storage to supply power.
On-grid systems are connected to the utility grid, allowing you to use net metering and draw electricity from the grid when needed. ☀️ Why is my solar panel producing less power than expected?
Reduced output can be caused by shading, cloudy weather, dirt or debris on the panel, or improper installation angle.
Regular cleaning and proper positioning can significantly improve performance. 🔗 Should I connect my solar panels in series or parallel?
A series connection increases voltage and is ideal when matching your inverter’s voltage requirements.
Parallel connection keeps the voltage the same while increasing current, helping reduce power loss from partial shading.
Always ensure your final wiring configuration matches your inverter or charge controller’s voltage and current specifications. ⚡ What does “12V” mean in the product title? Why is it different from the panel's actual voltage?
When you see a title like “XXX Watt 12V Solar Panel,” the “12V” refers to the system compatibility, not the panel’s operating voltage.
These panels typically have a higher operating voltage (around 18V VMP), which is necessary to efficiently charge a 12V battery system through a charge controller.
