1. California: 47 percent with 971 megawatts
2. New Jersey: 14 percent with 293 MW
3. Colorado: 5 percent with 108 MW
4. Arizona: 5 percent with 101 MW
5. Nevada: 5 percent with 97 MW
6. Florida: 4 percent with 73 MW
7. New York: 3 percent with 54 MW
8. Pennsylvania: 3 percent with 54 MW
9. New Mexico: 2 percent with 45 MW
10. North Carolina: 2 percent with 42 MW
New Jersey has made its way to second place with some major small-scale solar initiatives. Rooftops and utility poles across the state have gotten the solar treatment and all that distributed solar has added up to a nice chunk of MW.
Pennsylvania and North Carolina were interesting additions, as solar programs in other areas, like the Southwest, have gotten a bit more attention. But it is worth noting that there is over a 900 MW gap between California and North Carolina. California is really at the level I wish all states would strive for, and while 42 MW is nothing to sneeze at, that type of number making our top ten shows we have a much longer way to go overall.
