How do solar panels work?

You're likely most familiar with PV, which is utilized in solar panels. When the sun shines onto a solar panel, energy from the sunlight is absorbed by the PV cells in the panel. This energy creates electrical charges that move in response to an internal electrical field in the cell, causing electricity to flow.

How do solar panels create electricity?

But if you want to explore how solar panels create electricity a bit more, we'll explain what you should know. Solar cells are typically made from a material called silicon, which generates electricity through a process known as the photovoltaic effect.

How does home solar power work?

Here’s a step-by-step overview of how home solar power works: Excess solar energy is stored in batteries or pushed onto the grid to power local systems (like your neighbor’s house!) Now that we’ve covered the basics, let’s break down how solar panels work in more detail. How does solar power work? The photovoltaic effect explained

What is solar energy & how does it work?

Solar energy is the radiant light and heat that the sun emits. For centuries, humans have harnessed this energy in various ways—whether it was for heating homes, drying crops, or even powering solar ovens. However, in recent decades, technological advances have allowed us to convert sunlight into electricity efficiently.

How do solar cells work?

Here's how it works: Solar cells have two layers of silicon. Each one is specially treated, or "doped," with phosphorus and boron to create the positive and negative sides of the solar cell, respectively. When photons hit the solar cells, they create an electric field at the junction between the layers.

How does photovoltaic (PV) technology work?

Learn the basics of how photovoltaic (PV) technology works with these resources from the DOE Solar Energy Technologies Office. Solar photovoltaic modules are where the electricity gets generated, but are only one of the many parts in a complete photovoltaic (PV) system.
