One is positive anode and the other is negative cathode.
Photovoltaic cells solar panel.
Photovoltaics often shortened as pv gets its name from the process of converting light photons to electricity voltage which is called the photovoltaic effect.
Solar panels actually comprise many smaller units.
Solar cells also called photovoltaic cells convert sunlight directly into electricity.

The grape solar 300 watt monocrystalline pv solar panel uses high efficiency solar cells made from quality silicon material for high module conversion efficiency long term output stability and reliability.
A solar cell arrangement is known as solar module or solar panel where solar panel arrangement is known as photovoltaic array.
Electrons in these materials are freed by solar energy and can be induced to travel through an electrical circuit powering electrical devices or sending electricity to the grid.
A photovoltaic system also pv system or solar power system is a power system designed to supply usable solar power by means of photovoltaics it consists of an arrangement of several components including solar panels to absorb and convert sunlight into electricity a solar inverter to convert the output from direct to alternating current as well as mounting cabling and other electrical.
The solar cell is a two terminal device.
