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？

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

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

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.

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 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.
