BOULDER - The University of Colorado-Boulder has doubled the amount of solar power it produces following the completion of an array on the east campus.

The ground-mounted, 500-kilowatt system can produce 725,000 kilowatt-hours of energy per year, according to a press release from the university. It is the largest array on campus and CU's first ground-mounted system.

The array was developed and built by Panasonic Eco Solutions North America with local support from Boulder-based Lighthouse Solar Inc., the release said. Financing was provided by a combination of Colorado Amendment 37 rebates and incentives via Xcel Energy Inc. (NYSE: XEL), as well as federal tax credits and third-party financing.

CU-Boulder will be able to purchase the panels in seven years and will be able to sell power back to Xcel Energy.

In total, panels on the CU-Boulder campus generate about 1,000 kilowatt-hours of energy, which is enough to power about 200 average-size houses.
