FAQ
First, make sure to follow the installation instructions correctly. We use 3M VHB tape, a very strong double-sided tape designed for high-strength bonding. Even at high speeds, where the roof faces significant wind pressure, the VHB tape's strong adhesive power ensures that the EcoFlow HeatGuard Solar Film stays firmly attached to the roof. This tape is also designed to handle different temperature changes and the dynamic pressure from vehicle speed, so under normal conditions, the solar panel won't come off due to high speed.
Products that have been installed and have no quality issues cannot be returned or exchanged. Please thoroughly inspect the product and confirm your requirements before installation. If issues arise due to special structural designs or not following the manual, returns and exchanges will not be possible after installation. Additionally, do not use the product in extreme weather conditions like hail or typhoons, as any damage caused will not be covered under the warranty. If you have any questions, please contact customer service, and we will be happy to assist you.
All of our products support IP68 waterproof capability, which can handle various water immersion scenarios, cleaning, dust, and other factors, so you can use them with confidence.
This solar panel is waterproof, dustproof, and UV-resistant, and can withstand high temperatures, low temperatures, rain, and snow. However, damage caused by using this product in harsh or extreme weather conditions (such as hail or typhoons) is not covered under warranty.
EcoFlow HeatGuard Solar Film is lightweight and usually does not significantly increase the vehicle's load.
Yes, but their efficiency will decrease. Winter has shorter daylight hours, and low temperatures may affect battery charging and discharging performance. It is recommended to regularly check whether the solar panels are covered with snow in winter to maintain good power generation capability.
Solar panels require sunlight to generate electricity. They can still produce a small amount of power on cloudy days, but with reduced efficiency. At night or in extreme weather conditions, their power generation capacity will significantly decrease or stop, so using energy storage equipment is recommended.
Yes, but their efficiency will be lower. Winter has shorter daylight hours, and low temperatures can affect the performance of the batteries. It is advisable to regularly check if the solar panels are covered by snow during winter to maintain good power generation capacity.
Typically, they can endure temperatures ranging from -40°C to 85°C, though extended exposure to high heat might reduce their efficiency.
Solar panels are quite light, with each panel weighing around 5.6 kg, so they generally don't add much weight to the vehicle.
