Solar lights work in the following manner:

- The most important part of a solar light is the solar panel. This takes sunlight as input and convert it to electrical current

- The current then goes into a battery where the energy is stored

- The charging continues throughout the day

- A special sensor detects when the evening comes and turns on the solar light, which uses the energy in the battery. This sensor turns off the light when daylight arrives (assuming the energy lasts all night)

- And repeat next day...

Just to provide a bit more explanation, the solar panel is the main part which provides energy using the photo-voltaic effect. To explain: the solar panel has multiple layers of crystalline silicone and chemicals. As sunlight passes through the solar panel, it excites the negatively-charged electrons and these in turn are pushed into the positively-charged spaces - making a charge.

Sun-powered lights come with photovoltaic cells or solar panels. The photovoltaic cells are meant for transforming sunlight into the energy that the solar street lights require.

At daytime, the solar panels or photovoltaic cells harness the energy they obtain from sunlight, and then they transform this energy into solar energy. After that, the energy is stored in the batteries of the fixtures. Such energy is used by the lights to provide lighting at dusk.

Sun-powered street fixtures are commonly designed with a light sensor. This feature could detect the absence or presence of illumination. It allows the solar lights to turn on at twilight automatically, turn off at sunrise, and charge on its own.

Similarly, these solar lights typically come with a motion sensor that allows the illumination to brighten when it discloses someone’s coming and dims when someone is gone.

And, since these solar fixtures work on sunlight, the weather conditions can have a remarkable impact on their light output and running time. So, make sure that the solar panels are positioned in a location where they could have complete access to direct sunlight in the daytime.

Basically, they use the energy that the sun radiates during the day time. They convert that energy into something that they can use as fuel to produce their very own light.The science behind this is that photovoltaic cells absorb sunshine during the day, which is their recharging way. They gradually increase their energy, and batteries start to get charged up. Then, they start using this acquired energy to produce light during the night.
