- 【25% High-Efficiency】AeternaSol 200W N-Type A+ Grade Cell with 18 BB Full-Welding Busbars delivers a 25% efficiency rate and stable output. A+ grade monocrystalline silicon minimizes microcrack risks, and when combined with 18BB silver-containing busbars, it ensures lower degradation (≤1% in the first year, ≤0.4% annually) and an extended service life. - 【Exclusive IP68 Junction Box】AeternaSol solar junction box is equipped with potting technology. it prevents water or steam from reaching the wires inside, minimizes the risk of short circuits to the greatest extent, and effectively inhibits rust and corrosion. Its thermal conductivity ensures superior heat dissipation and an extended lifespan. - 【11 AWG 100% Oxygen-Free Copper Wire】Outperforming other copper-clad aluminum cables, AeternaSol’s extra-thick oxygen-free copper wire delivers superior electrical conductivity and can withstand up to 25A current. Beyond the standard insulation layer, the wire is also sheathed in a UV-resistant jacket?all of which extends its lifespan far beyond that of conventional alternatives. - 【Durable MC4 Connector】Featuring galvanized copper pins encased in a larger PPO shell, our standard MC4 connector outperforms aluminum-pin connectors with a higher current rating. Its robust PPO shell also ensures superior compatibility with other connectors - 【More Durable Aluminum Alloy Frame】AeternaSol aluminum alloy frames are sturdier than steel frames?they retain a sleek shine for years while resisting rust and corrosion. Additional frame sealant prevents air from corroding the monocrystalline cells, and pre-drilled holes on the frame ensure effortless installation - 【10-Year Seller Support & 25-Year Performance Guarantee】We provide 10-year seller support and a 25-year performance guarantee of maintaining 84.5% power output over the period. If you encounter any issues with our solar panels or services, feel free to contact us anytime. We’ll try our best for you!

Product description

Why is the actual power output lower than 200W?

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

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

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

What if I receive a scratched or defective panel?

Why is the actual power output lower than 200W?

The rated 200W 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 200W 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 12V system.

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

To set up an off-grid solar system, you need a solar panel, a charge controller to regulate current, and a battery to store power. Also, use adapter kit cables for connections and tray cables for the deep-cycle battery.

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 voltage remains the same. Both can optimize power output.

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.
