Tucson Electric orders 11 MW of SunPower solar technology for rooftop installations

San Jose, Calif., March 28, 2011 — Tucson Electric Power granted SunPower Corp. a contract to provide 11 MW of solar power systems technology for the utility’s TEP Bright Roofs program.

During the next three years, TEP will use the SunPower technology to install, own and operate multiple solar power systems on leased rooftop space atop schools and other large public buildings in the Tucson area.

The solar installations will be connected directly to neighborhood distribution circuits where the rooftops are located, and will generate enough renewable power to serve more than 1,800 Tucson homes.

TEP is purchasing the SunPower T5 Solar Roof Tile product, the solar industry’s first non-penetrating rooftop product that combines a high-efficiency SunPower solar panel, frame and mounting system into a single pre-engineered unit.

Tilted at a five-degree angle, the T5 Roof Tile system nearly doubles the energy generated per square meter compared to conventional systems that are mounted flat onto commercial rooftops.

TEP’s solar energy resources help the company comply with Arizona’s Renewable Energy Standard, which requires Arizona utilities to increase their use of renewable power each year until it represents 15 percent of their energy in 2025. In 2011, the policy calls on TEP to secure 3 percent of its power from renewables, including solar energy, wind, biogas and other resources.
