On a clear sunny day, around noon,
you receive around 800-1000 W/m² solar power.
This is when the sun is at its highest point and the intensity of the sunlight is strongest.
When you are under the shade of a tree
you receive around 80-200 W/m² solar power.
Roughly around 10% to 20% of the direct sunlight
With Thin or light cloud cover
you receive about 50% to 70% of the direct sunlight.
This corresponds to roughly 400 to 700 W/m²
With Moderate Overcast
you receive about 30% to 50% of the direct sunlight.
This translates to roughly 240 to 500 W/m²
With Heavy Overcast
Under heavy overcast conditions, the sunlight is further reduced to about 10% to 30% of the direct sunlight.
This means you are still getting roughly 80 to 300 W/m² solar irradiance
tl;dr
When the sun is out, you should be out too.
Doesn't matter if you are in shade or if there are clouds
YOU.
ARE.
STILL.
GETTING.
THE.
BENEFITS.
