The answer is yes and no.
Solar lights are powered by the sun, so they do not need electricity from an outside source, but they do require some type of energy to charge up the batteries that power them.
Solar lights work by collecting the sun’s rays and converting them into electricity via photovoltaic cells. This electricity is stored in a rechargeable battery for later use, when it is dark outside and the lights are needed. This means that during the day, your solar lights will be collecting energy from the sun and storing it in their battery for nighttime use.
The amount of energy collected varies depending on how much sunlight is available. In areas with more direct sunlight, more energy can be collected and stored in the batteries.
On cloudy days or when there isn’t much sunlight available, less energy will be collected. This means that depending on your location and climate, you may need to supplement your solar lights with a backup power source such as an AC outlet.
Conclusion:
In conclusion, outdoor solar lights do not require an external source of electricity to function but do need some type of energy to charge up their batteries. Depending on your location and climate, you may need to supplement your solar lights with a backup power source such as an AC outlet if there isn’t enough sunlight available.
