Campbell Soup Co. said it has completed installation of a 4.4-megawatt solar energy system at its 38-acre Camden headquarters, including panels mounted to rooftops, on a reclaimed brownfield, and on canopies built over employee parking lots.

The food company says the solar project, which was announced last May, will generate about 5 million kilowatt hours a year, or about 20 percent of the campus' annual energy demand. Under terms of a 20-year power purchase agreement, Campbell will pay a fixed rate that is currently "well below" its current power costs.

The project was developed by BNB Renewable Energy Holdings using systems developed by SunPower Corp. BNB and financial company Orix USA will own the system, which is being financed through Public Service Electric & Gas Co.'s solar loan program.

The Camden project is one of several renewable energy installations at Campbell facilities in the United States.
