Shorter Days + Heavy Rain = Solar Squeeze?
Shorter Days + Heavy Rain = Solar Squeeze? Looking at the current spell of rain and cloud across where I live, it’s clear why winter can feel like a double whammy for solar panels: Fewer daylight hours Thick cloud reducing light intensity Rain limiting peak generation periods But here’s the interesting bit… ☁️ Solar Panels Don’t Need Direct Sunshine Even on overcast days, panels still generate electricity. They work from daylight , not just bright sunshine. Output may drop to 10–30% of peak summer levels, but it rarely drops to zero during daylight hours. And rain? Rain actually cleans panels , washing away dust and bird droppings — improving efficiency when the sun does reappear. ⚡ Winter Solar Reality (UK Perspective) In the UK: June can produce 4–6 times more solar energy than December. But winter demand is higher (heating, lighting, appliances). That’s where battery storage really earns its keep. In your case, with your substantial battery s...
