The University installed a new 1-megawatt system on the roofs of its event center, a recreation center and a parking garage late last month.
The school just received its first bill since the system went in, said Joe Sugg, who heads up the University’s energy program.
“So we’re still figuring out how much this will save us,” he said.
The University has made a pledge to be carbon-neutral by 2016, just five years off, Sugg said.
“It’s not so much an investment in solar,” Sugg said. “It’s an investment in environmental justice, and it’s an investment in our core values as a Jesuit institution.”
Sugg said the university is aggressively going after its goal to reduce its carbon emissions in order to meet its goal.
That means Santa Clara is using a diverse mix of green technologies to cut into its carbon emissions. It recently opened a new smart grid that will allow it to use its energy more efficiently and to produce its own power through biofuel, wind, solar and other production techniques.
The addition of this photovoltaic solar array doesn’t make a huge dent, Sugg said. It only accounts for 9 percent of campus use during peak production, Sugg said.
“But solar is a tremendous tool when it comes to shaving our peaks,” Sugg said.
The university uses the most energy during the summer, having peaks sometimes more than 20 percent greater than its average use, Sugg said.
“We’re penalized financially for big spikes in our peaks like that,” he said.
Adding solar to the university’s energy mix should reduce energy costs and save the university big money, Sugg said.
“Then we can use that money to invest in other technologies that will help us reduce our carbon footprint,” he said.
The 1-megawatt system has been added to a 50-kilowatt system installed on the university’s administrative building in 2007. It is expected to eliminate 23,000 tons of carbon dioxide emissions, which is equivalent to reducing gasoline use by 2.4 million gallons, according to a press release from the college.
