One of the largest solar electricity systems will be constructed at the Cal State Hayward campus this summer, according to California State University authorities.

The 1.05-megawatt on-site solar system will be manufactured and installed by Berkeley-based PowerLight Corp.

It will deliver approximately 30% of the campus' peak electricity demand during the summer months.

The system will generate about 1.45 million kilowatt hours annually, producing enough electricity in the daytime to power the equivalent of more than 1,000 homes.
