 {{ http://img.mousetrap.net/misc/wattsunderconditions.jpg}}Based on [[https://en.wikipedia.org/wiki/Orders_of_magnitude_%28illuminance%29|lux measurements]], we can estimate how sky clarity/brightness affects the amount of power theoretically available to the panel.
 Takeaways:  overcast skies greatly reduce output, and there is no meaningful power available at sunrise/sunset.
