Under the contract, SunPower will sell its T5 Solar Roof Tile product, a non-penetrating rooftop product that combines SunPower solar panel, frame and mounting system into a single pre-engineered unit.

Over the next three years, TEP will install, own and operate multiple solar power systems on leased rooftop space atop schools and other large public buildings in the Tucson area in the US state of Arizona.

The installations will be connected directly to neighborhood distribution circuits where the rooftops are located.

TEP chairman, president and CEO Paul Bonavia said SunPower’s high-efficiency solar technology will enable the company to produce more power per installation, but it is also cost-competitive, easy to install and low maintenance.

SunPower said the solar installations are expected to generate enough clean power to serve approximately 1,800 Tucson homes.

TEP said its 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% of their energy in 2025.
