Scottsdale was among the first school districts in the state to put solar panels on campus roofs, in 2009 at Coronado High School and the Desert Mountain High School/Mountainside Middle School campus.

Since then, panels have been installed at Chaparral, Arcadia and Saguaro high schools, and Copper Ridge School. This summer, panels are being added to Desert Canyon Middle School.

Salt River Project recently donated a small rooftop array to Tavan Elementary School, and that 13.2-kilowatt project just went online last month.

New Jersey edged out California in the first quarter of this year for the lead in solar installations with 174 megawatts (see below for state-by-state details from USSMI -- sorry, California).

And the New Jersey solar miracle might keep rolling along, despite threats to derail its momentum.

Financial terms weren't disclosed. The settlement, which covers civil suits and a case pending before the U.S. International Trade Commission in Washington, extends to all customers, suppliers and licensees of the companies, they said in a joint statement.

DuPont Co. (DD) filed a patent-infringmenet lawsuit today accusing SolarWorld AG (SWV) of selling photovoltaic cells using a material the chemical company said it invented. 

The suit, filed in federal court in Portland, Oregon, is over a conductive paste that coats the front side of a solar cell.  The paste is made by a unit of Heraeus Holding GmbH and supplied to SolarWorld's U.S. unit, according to the complaint.
