4 FAQs about Home photovoltaic panels can generate electricity

How do solar panels create a usable electricity system?

Here's how solar arrays create a usable electricity system for your home: 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.

How do solar photovoltaic cells convert sunlight to electricity?

Solar photovoltaic cells are grouped in panels, and panels can be grouped into arrays of different sizes to power water pumps, power individual homes, or provide utility-scale electricity generation. The efficiency that PV cells convert sunlight to electricity varies by the type of semiconductor material and PV cell technology.

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.

What is a photovoltaic (PV) cell?

A photovoltaic (PV) cell, commonly called a solar cell, is a nonmechanical device that converts sunlight directly into electricity. Some PV cells can convert artificial light into electricity. Sunlight is composed of photons, or particles of solar energy.
