Solar cell, are you talking about the board that has some electricity when the sun shines and no electricity when the sun doesn't? Or is it an energy storage device that has electricity even when the sun doesn't shine? What you said makes some sense. If you can't design the device you want under the existing conditions, you can also try it yourself to see where the problem lies.

It is mainly cloudy. If the energy supply is insufficient, how can we ensure that the lights are on! If we cannot ensure that the lights are on on cloudy days, it will definitely not work!
