Solar panel efficiency in Winter / Cloudy weather / Indirect sunlight

What is the efficiency of solar panel in Winter during Sunny / Cloudy days ?

Does solar panel work with indirect sunlight or when there is cloudy weather ?

Solar panels are the most efficient when the sunlight is direct and strong.

Efficiency of solar panels:

• Direct and strong sunlight - Highest electricity production efficiency
• Direct and moderate strength sunlight - Good electricity production efficiency
• Direct sunlight through clouds - Weak electricity production efficiency
• Indirect sunlight - Weak electricity electricity production efficiency
