How does solar photovoltaic manufacturing work?
In the United States, solar photovoltaic manufacturing is highly automated. Machines do the majority of work: cutting semiconducting materials, such as crystalline silicon, into wafers, turning them into solar cells, and assembling the solar cells into solar panels.
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.
Why do we need more workers to install solar panels?
As solar power becomes more cost-effective, it has the potential to make up a larger share of growing U.S. energy needs. And as it expands in usage, there will be a growing need for more workers—manufacturing workers to make solar panels, construction workers to build power plants, solar photovoltaic installers to install solar panels, and so on.
Are solar photovoltaic systems considered electrical equipment?
Answer: Yes. The State Electrical Code adopts by reference the 2023 edition of the National Electrical Code (NEC). Solar photovoltaic systems fall within the definition of “equipment” as it is defined in the NEC. See NEC Articles 100, 690, 691, 705 and other applicable articles for all pertinent definitions.
