Solar panels can still produce electricity on cloudy or rainy days, though their efficiency may be reduced compared to sunny conditions. With more than 300 sunny days per year in Arizona, cloudy and. . Solar panel systems rely on the photovoltaic (PV) effect to convert sunlight into electricity. Naturally, weather conditions such as clouds, rain, and snow can significantly impact how much energy your system produces. However, one of the most common concerns among homeowners and businesses is how effective solar panels are in cloudy and rainy weather.
