The rise is set to continue.
Solar power is about to reach an inflection point. A new report released on Thursday claims that installations in the United States will double in just four years’ time, thanks largely to developments in California, which accounted for around half of all installations.
This estimate is from the research group Wood Mackenzie, who along with the Solar Energy Industries Association, found that there are now more than two million photo-voltaic solar installations in the country, just three years after passing the one million mark. The teams expect this pace to increase, reaching three million by 2021 and four million by 2023.
