According to the latest U.S. Solar Market Insight report, the 2,051 MW installed marks the eleventh consecutive quarter in which more than a gigawatt of PV was installed. Utility-scale solar installations accounted for 53 percent of all installed PV in the first half of this year. An additional 7.8 GW is scheduled to come online this year, bringing more solar capacity online in the second half of this year compared to what has come online in a single year.
California represented 50 percent of the non-residential market installations in the second quarter of the year, the study said. The U.S. non-residential market segment grew 5 percent over the first quarter and 50 percent year-over-year.
GTM Research states that by 2021, more than 30 states will add more than 100 MW of annual capacity, with 20 of those states hosting more than 1 GW of total operating solar PV.
