Solar Power How Do Solar Panels Work

Solar panels are made up of these small things called pv cells and many pv cells linked together make a solar panel.

Solar power how do solar panels work.

How do solar panels work. Solar panels work by absorbing sunlight with photovoltaic cells generating direct current dc energy and then converting it to usable alternating current ac energy with the help of inverter technology. Solar panels work by converting sunlight into electricity at the atomic scale. Solar panels contain cells of semiconductive material usually silicon usually encased in a metallic frame and tempered glass.

When solar cells are struck by light they produce a flow of electrons or electric current. Solar energy works when the photons of an atom knock the electrons free from atoms generating a flow of electricity. When subject to sunlight photovoltaic cells create a flow of electric charge inside the solar panel due to the photoelectric effect. Compared with other renewable energy systems panels are characterized by their lack of movement.

This entire energy conversion process from the panel to your house s outlets is known as the photovoltaic effect. Solar panels actually comprise many smaller units. Most solar cells are made out of silicon. Since this process happens at such a small scale it is invisible for humans.

This flow travels in a circuit of wires that connect groups of solar panels called arrays.
