Stanford Campus Residential Leaseholders (SCRL) hopes to woo President John Hennessy as well as other faculty and staff as it pushes its solar panel campaign. The organization is urging Stanford community members to install photovoltaic panels on their homes in order to lower the University’s carbon footprint.

If SCRL — which has partnered with solar panel design and installation company SolarCity — rounds up enough supporters within a 15-mile radius, homeowners will benefit from a 20 percent group discount. Coupled with state and federal rebates, the net installation price could range from $20,000 $50,000 — about half the market price.

“If the threshold [for the discount] were met, we could offset a million pounds of carbon over the next 20 to 30 years,” said Mary-Lou Zoback, the project’s chair.

But time is running out for SCRL. Even with the extension of the discount deadline from next week to Sept. 28, Zoback said the program, which was launched in mid-May, is still having trouble meeting the new deadline due to the panels’ high cost.

Zoback has not lost hope. She claimed that Hennessy has expressed some interest in installing a solar panel system in his home, potentially putting his stamp of approval on the initiative. She also said that if the Stanford Campus Recreation Association agreed to install solar panels on top of its pool and tennis club, SCRL would be 50 kilowatts closer to its goal of installing 175 kilowatts worth of panels.

According to Zoback, however, SCRL will need about 50 more homes to sign on to the initiative if these efforts fail.
