Community Energy's solar division completed financing on the project last month, the Radnor-based company said in a statement. Plans call for installing 20,000 solar modules in ground-mounted arrays.

Exelon Generation has contracted to purchase 7.5 million kilowatt-hours a year for 15 years, the bulk of the project's estimated 8 million kilowatt-hour annual output. Other customers committed to purchasing a share of the output include Franklin & Marshall College, Millersville University and the Philadelphia Phillies, Community Energy said.

The racks for the panels are completely in place, and about one quarter of the panels have been installed, Community Energy Solar Vice President  Thomas Tuffey said. The rest should be installed over the next two weeks. 

"I think we're pretty much on schedule," he said.

Completion is targeted for fall. Funding has come from the Sustainable Energy Fund, the state-funded Ben Franklin Technology Partnership and other state sources, Community Energy said.

Community Energy is not disclosing the project cost, Tuffey said.
