Constellation will finance, own, operate and maintain the system, and Johnson Matthey will purchase electricity produced by the installation under a 20-year power purchase agreement.

The solar installation will utilize PV panels from SunPower Corporation, which will also design and build the system.

Construction of the system has begun and is expected to be completed in the first quarter of 2011.

The PV project will be ground-mounted on approximately 21 acres and utilize single-axis tracking to optimize the exposure of the panels to sunlight.
