How Do Solar Panels Work?

Solar panels are devices that convert light into electricity.

They are called “solar” because they rely on the sun for their power. Solar panels are made up of many smaller units called solar cells. Solar cells are made of semiconductor materials, such as silicon. When sunlight hits a solar cell, it causes electrons to be knocked loose from their atoms, causing electrons to flow through the silicon. This flow of electrons is called an electric current, and it can be used to power electric devices.

The electricity produced by a solar panel can be used to power lights, appliances, and even homes. Solar panels are becoming increasingly popular as a source of renewable energy.


Solar panels are very efficient at converting sunlight into electricity.

They can convert around 15-20% of the sunlight that hits them into electricity. This means that a typical solar panel can produce enough electricity to power a light bulb.

Solar panels are used in a wide variety of applications. They are often used to power homes and businesses, and are also used in portable solar devices such as solar-powered calculators.


There are three main types of solar panels: monocrystalline, polycrystalline, and thin film.

Monocrystalline solar panels are made out of a single large crystal of silicon. They are the most efficient type of solar panel, but they are also the most expensive.

Polycrystalline solar panels are made out of several smaller crystals of silicon. They are less efficient than monocrystalline panels, but they are also less expensive.

Thin film solar panels are made out of a thin film of material, such as cadmium telluride. They are the least efficient type of solar panel, but they are also the least expensive.

Which type of solar panel is right for you depends on your needs and budget. If you want the most efficient solar panel possible, monocrystalline is the way to go. If you’re on a budget, polycrystalline or thin film might be a better option.
