Solar photovoltaic (PV) power generation is the process of converting energy from the sun into electricity using solar panels. Solar panels, also called PV panels, are combined into arrays in a
At a high level, solar panels are made up of solar cells, which absorb sunlight. They use this sunlight to create direct current (DC) electricity through a process called "the photovoltaic effect."
To boost the power output of PV cells, they are connected together in chains to form larger units known as modules or panels. Modules can be used individually, or several can be connected to form arrays.
The majority of the world''s solar power comes from solar photovoltaics (solar panels). China has dominated the solar industry, holding more than 37 percent of the global installed capacity

PV panels can be connected in groups to form a PV array. A PV array can be composed of as few as two PV panels to hundreds of PV panels. The number of PV panels connected in a PV
Solar energy can be harnessed two primary ways: photovoltaics (PVs) are semiconductors that generate electricity directly from sunlight, while solar thermal technologies use sunlight to heat water for
How do solar panels work? Learn the photovoltaic effect, solar panel technology, and efficiency in 2025—clear steps, real-world examples, and pro tips from SolarTech.
At a high level, solar panels are made up of solar cells, which
Solar panels rely on the photovoltaic (PV) effect to create power. Sunlight is transmitted through photons – massless particles of electromagnetic radiation – which contain varying amounts
A photovoltaic system employs solar modules, each comprising a number of solar cells, which generate electrical power. PV installations may be ground-mounted, rooftop-mounted, wall-mounted or
