One of the world’s leading scientific research institutes is adding 500kW of rooftop solar, establishing environmental leadership while preserving landmark buildings.
San Diego, CA – The Salk Institute of Biological Sciences has selected San Diego solar company Stellar Solar to design and install a new 500 kW rooftop solar electric system for its architecturally-renowned campus in La Jolla, according to Tim Ball, the Institute’s senior director of facilities services.
“As one of the leading scientific research institutes, we saw this as an important opportunity to also demonstrate our environmental leadership,” Ball said. “And capturing kilowatts from sunshine to help power our efforts seemed like a step in the right direction.”
The project also combines the sustainability of solar energy with the sensibility of architectural preservation, Ball pointed out. Despite the Institute’s bold design and modern appearance, the buildings were completed in 1965 and officially designated a National Historic Landmark in 1991. As such, providing a long-term strategy to care for the facility’s energy needs was a key part of the decision.
Ball said that the 500kW system, consisting of more than 2,350 solar panels, will cover the roof area of all four major buildings on the campus but will not be visible from the ground. “Along with lowering our carbon footprint, we wanted to make sure the appearance of these impressive buildings was not impacted in any way,” Ball said.

The environmental impact of the solar arrays, however, will be significant; they will keep out of the atmosphere about 846,000 pounds of carbon dioxide annually – along with nearly 800 pounds of sulphur dioxide and 1,240 pounds of nitric oxide, two of the major pollutants produced by power plants. Over the next 25 years, in fact, installing the solar system is equivalent to planting 128 acres of trees.
In addition, solar is seen as a way to help save money on the Institute’s energy bill, Ball said. “As a non-profit institution, we are always looking for ways to stretch budgets and save money,” he explained. “But as a research facility, we do use a lot of electricity. And although we get a very good rate from SDG&E, we found we could produce our own solar electricity onsite for a cost that was about 30% lower than what SDG&E charges us.”
Stellar Solar was selected to design and build the solar array because it was a local firm with a proven track record of success, Ball said. “Not many firms have been in the solar business as long as Stellar Solar has and we wanted to work with a group that could integrate themselves easily into our existing work on a weekly basis. Stellar has the know-how to do that,” he said.
Stellar Solar president Kent Harle said his firm considers it an honor to be selected to work on a high-visibility solar project such as this one. “The San Diego Union-Tribune calls the Salk Institute ‘the single most significant architectural site in San Diego,’” he said. “It is also significant that this site will now be solar-powered and we are so very proud to be a part of making that happen,” he said.
The solar modules for the project are being supplied by Trina Solar and the 500 kW power inverter is manufactured by SMA-America, Inc., Harle said.
