Raising photovoltaic panels on rainy days
Rainy days have a hidden bonus: the rain cleans dust and debris from your panels, which can actually increase efficiency once the clouds clear. For example, a 5kW solar system that usually produces ~20 units per day might still generate 5–7 units during a downpour. The exact amount depends on how thick the clouds are and how much light filters through. Even on heavily overcast days, there's still diffuse sunlight—scattered light that penetrates clouds and allows solar panels to. Solar panels continue generating electricity during rain and cloudy weather, though at reduced capacity compared to sunny conditions. The key factor is light. Residential solar panels are built for real life, not just picture-perfect, sunny days. Clouds roll in, seasons change, and rain happens. While solar energy thrives in bright, sunny environments, that doesn't mean it.
