What is ETFE and why is it better than PET or EVA?What else do I need to use this?

ETFE is a fluoropolymer material that offers excellent durability, UV resistance, and higher light transmittance. Unlike PET or EVA, it doesn't yellow over time and performs better in extreme outdoor environments.You will need a portable power station (a large battery) to store the energy generated by the solar panel. From there, you can power any USB or AC device.

Are ETFE solar panels fully waterproof?Will it work on cloudy days?

Yes, ZOUPW ETFE solar panels are IP67 or IP68-rated, meaning they are highly water-resistant and can withstand splashes, rain, and dusty conditions—ideal for outdoor use.Yes, but at a reduced efficiency. These high-conversion panels are still capable of generating meaningful power from diffused sunlight.

Do ETFE panels require special maintenance?How do I choose the right wattage?

Not at all. The non-stick ETFE surface is easy to clean with a soft cloth and water, and resists dirt and grime buildup better than traditional panels.Calculate the total wattage of the devices you need to run. We recommend adding a 20-30% buffer for future needs. Unsure?Contact our expert team for a free, personalized consultation.
