Solar vacuum tubes do not perform as efficiently in cloudy weather compared to sunny conditions. The reduced sunlight intensity and diffused radiation hinder their ability to generate as much heat or electricity. However, they are still capable of capturing some solar energy, though at a lower rate, even on cloudy days.
Solar vacuum tubes do not perform as efficiently in cloudy weather compared to sunny conditions. Cloud cover reduces the amount of sunlight reaching the tubes, leading to a decrease in their overall performance. However, solar vacuum tubes are still able to generate some heat even in cloudy weather, making them a viable option for solar heating systems in regions with less sunlight.
