EcoFlow 100W Flexible Solar Panel

In most cases, it is normal for a solar panel not to deliver its full nominal power. Some of the reasons why this happens, as well as some suggestions for getting closer to the nominal power figure, are given below. 1. Light Intensity. The amount of light shining on the panel will result in fluctuations to the power output. You are more likely to achieve nominal power output figures closer to those obtained under test conditions when using the product on a clear day during the midday sun, than when using the product in the morning or later in the afternoon. Weather conditions will also affect the amount of sunlight that shines on the panel. For example, you are much less likely to achieve the figures for nominal power in hazy, cloudy or rainy conditions. 2. Surface Temperature. The temperature of the solar panel surface will also affect the amount of power generated. The lower the surface temperature of the panel, the more power will be produced. For example, solar panels generate more power when used during the winter than during the summer, and this is completely normal. Solar panels generally reach temperatures close to 60 °C (140°F) during summer. This reduces nominal power by 10–15%, despite the higher levels of light shining on the panel. 3. The Angle of the Sunlight. Under good lighting conditions, the solar panel is able to stay where light hits perpendicular to the surface to achieve better light performance. However, most solar panels installed on the roof of an RV can only be installed in a tiled configuration, which prevents the panel(s) from being installed at the optimal angle, and this difference will result in a power output loss of approximately 5%-10%. 4. Panel Shading. The surface of the solar panel should not be shaded during use. Shading caused by shadows, foreign objects and glass can all greatly reduce power output. Performance Issues caused by Malfunctioning Panels: If the panel still isn't generating power or its output remains far below expected nominal power figures after addressing the issues above, there may be an issue with the panel itself. Please contact Customer Support for assistance.

This depends first and foremost on weather conditions. Generally speaking, on a clear day with no clouds in the sky, sunlight hitting the panel at a 90° angle usually generates 70 W–80 W of power in the 100 W panel (current light conditions are normally 800–900 W/m2 (74.3–83.6 W/ft2 ) with a panel temperature of 50°C (32°F) under test conditions. Nominal power ratings are based on 1,000 W/m2 (92.9 W/ft2 ) in AM1.5 conditions with a panel temperature of 25°C under test conditions. Power output figures close to nominal values were normally observed in the midday sun during the winter)

The operating temperature range of the solar panel is -20°C to 85°C (-4°F to 185°F). Please read the instructions carefully before using the solar panel and minimize large bends during use to avoid damage to the battery core. The panels are made of a special composite material, which is lightweight and able to bend to a certain degree, allowing them to be used flexibly on different surfaces of the roof. However, the solar panels are made of monocrystalline silicon wafers, and despite their flexibility, they should not be slammed on the ground during installation and use or stepped on or struck with foreign objects. Do not sit on the surface of the panels and do not bend the panels too far in order to prevent the monocrystalline wafers from breaking and affecting use. Damage caused by human force is not covered under the free warranty.

The solar panel can be bent on certain surfaces, but the more the panel bends, the less efficient it is. This is because panel power generation is best only when the entire panel has a consistent light source. When bent, different areas of the flexible solar panel are exposed to different amounts of light, reducing power generation efficiency.

Yes. Please read the description of in series and parallel connections in the User Manual carefully, paying particular attention to energy storage controller requirements and limitations on solar panel output, so as not to cause solar panels with different currents to be used in series without releasing their power and creating a 1+1<2 effect.

Yes. Connecting panels in parallel increases power through doubling the current. The maximum number of 100 W panels allowed in a parallel connection depends on the controller and energy storage equipment of your recreational vehicle. Please ensure that the energy storage system used in your vehicle supports a higher input current, and you should use wires with a diameter suitable to the output current to securely connect the panels in parallel.

Yes. There can be a lot of dust and foreign objects on the surface of the solar panel after the panel has been used outdoors for a long time, which block the light to a certain extent, reducing the power output. Regular cleaning can help keep the surface of the solar panel clean and free from obstructions and generate a higher power output. However, when cleaning, be careful to wipe the surface with soft materials to prevent hard materials scratching the surface of the panel and affecting the output.
