Advancing Solar Energy Growth
Constellation owns and operates one of the nation's largest solar power facilities with a total capacity of 242 megawatts (MW). As a low-carbon, low-emission energy source, solar offers a reliable path for customers seeking more sustainable solutions.
Constellation's Antelope Valley Solar Ranch One in Los Angeles County is one of the largest solar photovoltaic projects in the U.S. Its 3.8 million solar panels generate 242 MW of clean, renewable electricity, which is enough to power the equivalent of 75,000 homes. This project displaces approximately 140,000 metric tons of carbon dioxide (CO2) per year, an amount comparable to taking approximately 30,000 cars off the road.
Solar photovoltaic cells (PV cells) are the equipment that start the process of generating solar power. They're typically placed on rooftops or the ground for maximum sun exposure. When sunlight strikes panels, it is absorbed by semiconductor material within each panel that knocks electrons loose. The electrons then flow along wires within the PV cells to create electricity.
Some solar projects serve individual homes or businesses, while others provide power directly to the grid.
When building a solar generation project, it's important to select locations that will maximize sun exposure for the panel array. Flat areas with direct sunlight and minimal shadows are ideal. While a PV panel can still generate power when it is cloudy or dark, efficiency will be reduced.
