How Does Solar Work?
Learn the basics of solar energy technology including solar radiation, photovoltaics (PV), concentrating solar-thermal power (CSP), grid integration, and soft costs.
At the core of solar panels is the photovoltaic (PV) effect. When sunlight strikes the solar cells, it excites the electrons in the semiconductor material, causing them to flow through the material. This flow of electrons is what creates electricity. The more sunlight that hits the solar cells, the more electricity is generated.
Solar energy is one of the most promising renewable energy sources available today, offering a sustainable and clean alternative to fossil fuels. But how exactly do solar panels convert sunlight into usable electricity? The answer lies in the fascinating science of photovoltaic (PV) cells.
Solar energy is converted into electricity through the photovoltaic effect, a process where sunlight, composed of photons, agitates electrons in a semiconductor material (like silicon) within solar panels. Here's a deeper look into the full process: To find out how solar power works, you need to understand how panels are made.
AC is the type of electrical current used when you plug appliances into normal wall sockets. What's the difference between solar PV panels and solar thermal panels? Solar PV panels generate electricity, as described above, while solar thermal panels generate heat.

A PV cell is made of semiconductor material. When photons strike a PV cell, they will reflect off the cell, pass through the cell, or be absorbed by the semiconductor material. Only the
Solar panels work by converting incoming photons of sunlight into usable electricity through the photovoltaic effect.
When sunlight hits photovoltaic solar panels, the movement of excited electrons generates an electric field.
