SOLAR POWER growth in the US.
In the first quarter of 2019, the United States installed 2.7 gigawatts -DC of Photovoltaic power - the largest amount of solar deployed in Q1 in U.S. history and 10% above Q1 2018. Falling costs of solar projects helped drive this increase. The median reported PV system price in California, Massachusetts, and New York fell 7% for systems from 100 kW to 500 kW and 6% for systems from 500 kW to 5 MW.*
