Solar Panels do still generate power during cloudy and rainy weather. We have a rough guide below to solar panel power output relative to weather conditions. 100% power output - clear sky midday sun with the panel fully tilted toward the sun's position in the sky. 75-85% output - clear sky midday sun but with the panel laid flat. 50-65% output - thin cloud, or intermittent small clouds.
10-20% output - midday overcast sky or rainy conditions. 15A Solar charge controller, solar power controller with timer and light sensor. Pair MC4 with 5 meter 4mm²extension solar cable(5m red and 5m black).
