Understanding the Relationship Between PV Panels and Weather

Photovoltaic panel power generation directly responds to weather conditions like a plant follows sunlight. Whether you're a homeowner or commercial operator, knowing how temperature, cloud cover, and precipitation affect solar energy systems is crucial for maximizing ROI.

3 Weather Factors That Make or Break Solar Efficiency

• Temperature swings: Contrary to intuition, panels lose 0.3%-0.5% efficiency per °C above 25°C
• Cloud dynamics: Diffused light can still generate 10%-25% of normal output
• Snow/rain impacts: Properly angled panels self-clean but may lose 15%-40% output temporarily

Real-World Performance Data (2023 Industry Report)

Weather Condition	Output %	Duration
Clear Sky	100%	6.2h/day avg
Partial Clouds	65%-85%	3.1h/day avg
Heavy Rain	40%-60%	Seasonal
