SOLAR INSTALLATIONS IN US NOW EXCEED 2 MILLION AND COULD DOUBLE BY 2023, NEW FIGURES SHOW

There are now over 2 million solar photovoltaic (PV) installations in the U.S., according to new figures. The 2 million mark comes three years after installations hit 1 million, a figure it took the industry 40 years to reach. 

The numbers, from Wood Mackenzie Power & Renewables and the Solar Energy Industries Association (SEIA), were released Thursday.

Solar power can be harnessed in several ways, including through photovoltaic and concentrated solar power systems. Photovoltaic refers to a way of directly converting light from the sun into electricity.
