‘Morning all. Today’s rundown of solar energy news will be quick and painless — we’ll spare you the side commentary.

Empire Power Systems yesterday announced it will install the largest commercial rooftop solar installation in Arizona, via MarketWatch. The 2.4-megawatt solar energy system will reside atop an 850,000-square-foot building in Phoenix.

Duke Energy will team up with North Carolina Municipal Power Agency Number 1 (NCMPA1) to construct a one-megawatt solar installation, according to PRNewswire. The Shelby Solar Project will go forth under a 20-year power purchase agreement (PPA), under which the North Carolina agency will buy all the electricity generated from system.

New York’s Hudson Valley continues to be fertile ground for solar-related companies and solar installations. Precision Flow, a New York-based manufacturer and member of The Solar Energy Consortium, is expected to add about 190 jobs, via the Daily Freeman.

Solar Thin Films, Inc. — a company that makes (get this) solar thin-film amorphous silicon panels — today announced strong annual revenue growth, via MarketWire. The company also announced it shrank its net loss to a penny a share.

Finally today, Canadian Solar (NASDAQ:CSIQ) was downgraded to “Hold” from “Buy” by an analyst from Collin Steward, via BusinessWeek. Shares of CSIQ subsequently fell about six percent.

That’s all for now. Thanks for reading. We’ll see you back here tomorrow.
