A link on San Lorenzo Unified's website home page shows in real time how much energy is being generated by solar panels installed earlier this year throughout the school district.

"We anticipate saving between $350,000 and $450,000 a year," assistant superintendent Lowell Shira said. The district currently spends about $750,000 annually on power.

The link on the district's home page, www.slzusd.org, converts the energy generated into four categories: the equivalent number of 60-watt light bulbs burning eight hours daily for a year; the number of homes powered a year; tons of carbon dioxide saved; and the amount of carbon dioxide kept out of the atmosphere.

In addition, there is a graph showing how much solar energy is generated hourly, weekly, monthly and annually.

Shira said teachers can use the link monitoring the amount of solar power for science classes. It also allows the maintenance department to see if there are any problems with the panels, he said.

The solar panels were installed on parking shade structures at seven schools and at the district office on Usher Street. "They provide some shade for parking, but the primary purpose is to provide electricity," Shira said.

The panels, which cost $6 million, were funded by Measure O, an $83 million bond voters passed in 2008.

The bond is also paying for upgrading of athletic fields at the district's high schools, science labs and a digital arts center at San Lorenzo High, Shira said.
