2021 was an excellent year for the US Solar industry, with almost 24 gigawatts deployed across all states. This is reflected in the latest Solar Panel shipment data published by the Energy Information Administration: the US shipped 28.8 million kilowatts of solar panel capacity in 2021, breaking the previous 2020 record of 21.8 million kW. This figure includes imports, exports, and solar panels that are manufactured and used locally.
