Solar power is hot, literally and figuratively. In the first three months of 2014 alone, the U.S. has added 1,330 MW of solar PV. This is 79% (!) more than what was added in the first quarter of the previous year. To put things in perspective, this new solar capacity represents 74% of new electricity generation capacity in the U.S. during the period, followed by wind power at 20% and natural gas at 4%.
While utilities installed the most MW of solar, the #2 was interesting: It's the first time that residential beats commercial (aka non-residential) solar PV, with 232 MW for residential and 225 MW for commercial. This is a growth of 38% over Q1 2013 for residential PV, and a decline of 12% from Q1 2013 for commercial.
The total, cumulative operating solar PV capacity of the U.S. now stands at 13,395 MW, with 482,000 individual systems on-line as of the end of Q1 2014.
