Spacecraft that venture no farther than Mars regularly use solar panels to convert sunlight to electricity for their operations.

Each winglike panel can convert the sun's energy into 2,800 watts of electricity.

Usually, photovoltaic (PV) cells contained in solar panels convert the sun's energy directly into electric energy.

(Conventionally inexpensive organic solar panels convert 9% of the sun's energy into electricity.)

Photovoltaic panels convert sunlight to electricity.

This solar panel converts the light into electrical energy to power the watch.

Unlike the solar heat concentrators, photovoltaic panels convert sunlight directly to electricity.

By comparison, solar panels convert light into electric energy at an efficiency of approximately 6-20% for mass-produced panels, and above 40% in laboratory devices.

Photovoltaic panels convert sunlight directly to electricity with no emissions at all.

Photovoltaic systems (PV system) use solar panels to convert sunlight into electricity.
