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."

Solar panels operate on the photovoltaic effect, a phenomenon discovered by French physicist Alexandre Edmond Becquerel in 1839. This process occurs when photons from sunlight strike

Solar power systems that generate electricity consist of photovoltaic (PV) panels to harness sunlight and produce electric current. Solar panels absorb sunlight with silicon semiconductors and
View Details
Solar panels work by converting the light radiation from the sun to Direct Current (DC) electricity through a reaction inside the silicon layers of the solar panel.

When sunlight hits a solar panel, photons penetrate the anti-reflective coating and enter the silicon photovoltaic cells. Not all photons are absorbed–some reflect off the surface or pass through
