The US installed 1,393MW of solar PV in the second quarter of this year, taking the country’s cumulative capacity beyond the 20GW milestone.
This is the seventh consecutive quarter in which the US has installed more than 1GW, according to the ‘Q2 2015 US Solar Market Insight Report’ from GTM Research and the Solar Energy Industries Association (SEIA).
Meanwhile, GTM forecast that, with the second half of the year expected to be significantly larger than the first half, PV installations will hit a record 7.7GW in 2015, up 24% from 2014.
Growth is expected in all divisions of the solar sector, but residential solar will see the fastest growth.
The lowering costs of solar compared to traditional fossil-fuel alternatives has also become a key factor in solar deployment figures. Of the 16.6GW of utility-scale PV currently under development, 40% was procured mainly due to the economic competitiveness of solar.
GTM found that throughout the first half of the year, solar accounted for 40% of all the new electricity generation capacity that was brought online in the country.
Despite passing the 20GW mark with cumulative PV installations, the US’s top five states still account for nearly three-quarters of all deployment. Nevertheless 21 states now have more than 100MW of PV.
