Why the solar human induction light is not on?

Solar human induction light will not be bright during the day.

Generally, solar-powered lamps with human induction function will not be bright when the solar energy is charged, and it will only be bright after night when someone enters the induction range.

Full use of electricity does not cause waste, but the sensitivity of the human body sensitivity is closer. The special question is that now in summer, there are often non-sensing current answers, so it does not turn on.
