HAVE YOU EVER THOUGHT THAT THE LIGHT SOLAR LAMPS COULD BE CHARGED ON CLOUDY DAYS?
A question that is often mentioned is whether solar lamps for a house can be charged on cloudy or sunny days. The answer is yes.
Can the solar lights charge on a cloudy days
THE SOLAR CELL CHARGING UNIT IS SENSITIVE TO LIGHT DENSITY
Because the charging components of the solar panel are very sensitive to light density / luminous intensity. As long as the light density is enough, the solar panel can collect power and start its charging process to solar outdoor lights.
LIGHT DENSITY STILL EXISTS ON CLOUDY DAYS
Although direct sunlight will be blocked on cloudy days, the solar lights are still receiving charge. The clouds diffuse the strength of the sunlight, but the solar irradiance is still transmitted from the sun to the earth. So the solar power system still charges during cloud cover. Also, when puffy cumulus clouds cover the sun, from time to time sunlight will penetrate through holes in the clouds. Once it happens, the solar panels absorb not only direct sunlight but also sunlight reflected by the cloud. In cloudy conditions, sunlight or light intensity is sufficient to charge in most cases.
CLOUDY CITIES THE SOLAR LAMP MARKET IS BOOMING
Cities like San Francisco, Seattle, Portland, and Boston are famous for their cool, cloudy weather and don’t have the same sunny conditions as Las Vegas. However, the markets for solar street lights are booming simply because cloudy days can also provide solar street lighting with a considerable load.
CHARGING EFFICIENCY DURING CLOUDY DAYS
Although it can be charged on cloudy days, the charging speed will be slower than that. The irradiance on a cloudy day or in the shade may be only 1/2 or 1/5 of what it is on a sunny day. The good news is that charging efficiency can be better during cloudy days. During charging, the temperature of the solar panel is high in direct sunlight and the charging efficiency decreases.
On the other hand, the temperature is much more likely to be in the range where solar panel charging is highly efficient when it is cloudy. In short, the solar powered lighting system can be charged on cloudy days. If you live in a cool cloudy area, you can still buy solar systems like solar patio lights,Even on continuous cloudy days, most solar lights provide illumination with stored energy.
