Solar vacuum tubes can still work on cloudy days, although their efficiency is reduced. While direct sunlight is optimal for maximum energy production, solar vacuum tubes can still capture diffuse light from the clouds and convert it into usable energy. However, the amount of energy generated will be significantly lower compared to sunny days.
Solar vacuum tubes do work on cloudy days, although their efficiency may be reduced compared to sunny days. The vacuum tubes can still capture and convert solar energy, albeit to a lesser extent, making them a viable option for generating heat or hot water even in less ideal weather conditions.
Solar vacuum tubes can still generate some heat on cloudy days, although their efficiency may be reduced compared to sunny days. The tubes can still capture diffuse sunlight and convert it into usable energy, although to a lesser extent.
