When evaluated on a state-by-state basis, California generates more solar electricity than any other state in the country by a wide margin, accounting for a massive percentage of the nation's total utility-scale and small-scale photovoltaic generation. Driven by abundant sunshine, aggressive state renewable portfolio standards, and millions of installed residential and commercial rooftops, California consistently leads national output metrics. Other states like Texas and Florida also produce substantial quantities of solar power as utility-scale solar farms continue to scale rapidly across the American Southwest and Sunbelt regions to meet rising electricity demand.
