Solar energy in the United States has exploded over the past decade. In 2010, 667 megawatt (MW) was installed in homes. By 2020, this had increased by 27 times to over 18,061 MW.[1] At the same time, the cost of a residential solar system has come down to half of what it was, even before incentives are applied, and continues to drop.
