4 FAQs about Solar panel power

What are solar panels?

Solar panels, also called photovoltaic (PV) panels, are devices that convert sunlight into electricity. They are made up of many solar cells, typically crafted from silicon, that capture energy from the sun and generate direct current (DC) electricity.

How do solar panels work?

As we've explained, the solar cells that make up each solar panel do most of the heavy lifting. Through the photovoltaic effect, your solar panels produce a one-directional electrical current, called direct current (DC) electricity. Your home can't use DC electricity directly—it needs to be converted to alternating current (AC) electricity first.

Do solar panels generate electricity?

The more panels you install, the more electricity your system can generate. Even with solar panels on your roof, most homes remain connected to the electric grid. The grid is the system of power plants, substations, and power lines that deliver electricity to homes and businesses.

What type of electricity does a solar panel use?

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.
