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.
Can I connect multiple panels together?
Yes. Connect panels in parallel to increase current or in series to increase voltage. Make sure panels have the same voltage and specs. Use proper connectors and ensure your charge controller supports the total power.
What if I receive a scratched or defective panel?
Please contact our support team immediately. If the damage affects performance, we will work with you to resolve the issue promptly. We also recommend photographing the package and panel upon delivery for reference.
How should I clean or maintain the panel?
Use a soft cloth or sponge with water to wipe off dust, bird droppings, or stains. Avoid using harsh chemicals. Regular cleaning improves light absorption and helps maintain efficiency.
Is this panel compatible with my 12V system?
Yes, if your charge controller accepts a solar panel Voc of 26.02V or higher. Please confirm your controller’s specs before purchasing.
