Cloud, haze, shade and a poor angle will reduce that.\u003c\/p\u003e\u003ch3\u003eGood to know\u003c\/h3\u003e\u003cp\u003eA solar panel only produces power while it is in sunlight, and its rated wattage is what it can deliver under ideal conditions, so real-world output will usually be lower. Angle the panel toward the sun and keep it free of shade. Before you order, make sure the panel's connector and voltage are compatible with the power station or battery you plan to charge.\u003c\/p\u003e\u003ch3\u003eSetup and care\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eUnfold on a flat, stable surface angled toward the sun\u003c\/li\u003e\n\u003cli\u003eKeep the panel clean and free of shade\u003c\/li\u003e\n\u003cli\u003eConnect to a compatible device or controller before leaving it in the sun\u003c\/li\u003e\n\u003cli\u003eFold and store dry after use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently asked questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eDoes it work on cloudy days?\u003c\/strong\u003e\u003cbr\u003eYes, but at much lower output.
