100W Watt 12V Mono N-Type 18BB 25% Solar Panel Home RV Off Grid PV Home

Product Features

(25% High-Efficiency Power Generation Core)
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!

Product Description

Q&A

Why is the actual power output lower than 100W?

The rated 100W is based on Standard Test Conditions (STC): 1000W/m² irradiance, 25°C, and 1.5 air mass. In real use, panel angle, temperature, shading, wiring loss, and device efficiency affect output. So, actual power below 100W is normal.

What is the meaning of 12V in the product title? Why is this value different from the voltage of the solar panel?

When you open the product page, you will see a title like "xxx Watt 12 Volt Solar Panel". The "12V" here does not refer to the voltage of this solar panel (VOC or VMP), but to the fact that one xxxW solar panel is suitable for a 12V system.

How should I connect solar panels in my electrical circuit (series vs parallel)?

Solar panels can be connected in series to increase voltage while maintaining the current of one panel. In parallel, the output current adds up, while the voltage remains the same. Both can optimize power output.

What do I need to complete my off-grid solar power system?

A solar panel must connect to a charge controller for current regulation and a battery for power storage. Use adapter kit cables to wire the panel and controller, plus tray cables for the battery.

What if I receive a scratched or defective panel?

If you receive a scratched or defective panel, please take photos immediately and contact our support team. We will assist you with the next steps promptly.
