Solar panels are becoming increasingly common in our daily lives, but how do they actually work?

And are they different when used in space?

Basics of Solar Panels

Solar panels work by converting sunlight into electricity.

The process starts with the sun's radiation hitting the solar panels, primarily made up of photons.

These photons then dislodge electrons from atoms, generating an electric current.

This electricity can be used to power various devices and systems.

The Design and Function

The surface of a solar panel is made up of photovoltaic cells containing layers of semiconducting materials.

When photons strike the panel, they knock electrons loose, allowing them to flow freely.

The circuit inside the panel captures this flow of electrons, generating electricity.

Space Solar Panels

Solar panels used in space are largely similar to those on Earth, functioning on the same basic principles.

However, due to the harsh conditions in space, they are built to much higher standards.

Space solar panels are designed to withstand extreme temperatures, solar radiation, and micrometeoroid impacts.

Additionally, they are equipped with a protective glass covering to minimize degradation from hard radiation and other space hazards.

The need for sturdier and more efficient panels in space is crucial as they are not replaceable once deployed.
