Constellation Energy will develop two rooftop solar installations in Maryland, both funded partially by grants through the Maryland Energy Administration’s Project Sunburst initiative.

Constellation Energy will develop a 750kW on-site solar installation at Anne Arundel County’s Combined Support Services Complex in Millersville, Maryland, and a 500kW on-site solar installation at Coppin State University in Baltimore.

Constellation Energy will finance as well as own and operate the on-site solar installations, in return, both organizations will purchase the electricity produced by the systems at a reduced cost from Constellation Energy over a 20-year period.

The rooftop solar power system, developed for Anne Arundel County’s Combined Support Services Complex, is expected to offset 90% of the building’s annual electric consumption, saving the county an estimated $80,000 per year in utility costs.

The 750kW facility’s on-site solar power system will utilize approximately 3,060 roof-mounted crystalline photovoltaic solar panels and supply an estimated 900,000kWh of electricity annually.

Coppin State University’s on-site solar power system will supply electricity for its new Physical Education Complex, utilizing approximately 2,040 roof-mounted crystalline photovoltaic solar panels.

The system is expected to supply more than 600,000kWh of electricity annually.

In total, the Anne Arundel and Coppin State solar installations are expected to generate roughly 1.5 million kWh of electricity annually, and both systems are scheduled to begin producing electricity in spring 2011.
