The US increased its installed solar capacity by 142.8% in the first quarter of 2013 compared to the same period last year, according to figures provided by the US Federal Energy Regulatory Commission.

In April alone the country saw 33MW of new solar capacity installed and now boasts a 5.14GW installed operating generating capacity.

Some of the projects installed in April include Apple’s Data Centres Phase 1 and 2, which combined have a generating capacity of 21MW and are expected to come online in June 2013.

The commission also attributes April’s figures to SolarVision LLC’s 5MW Celina Solar Project I in Mercer County, Ohio, which is online. This solar project is expected to produce enough power to meet about 8% of the city of Celina’s total energy demand.
