The solar panels sparkle on the rooftop of HelioVolt’s 12,000 sq m manufacturing facility. Inside, an elaborate line of printing machines, lasers, chemical baths and ovens — with help from the occasional white-coated human being — transforms a sheet of glass less than a centimeter thick into a solar module in just over two and a half hours. The sheets are a far cry from the thick, polysilicon-based photovoltaic panels that still dominate the solar market. HelioVolt manufactures thin-film solar panels, so called because the modules are made by depositing an ultra-thin — a few micrometers at most — layer of the photovoltaic chemicals copper, indium, gallium and selenide directly onto a glass backing. Compared with conventional modules, the engineering and manufacturing processes are more complex, and thin-film panels are less efficient at converting sunlight to electricity. But their lower cost has many in the solar world — like HelioVolt CEO Jim Flanary — convinced that thin-film panels are the way to go as the industry matures. “If you can do this really cheaply and really quickly, you’ve got a winner,” says Flanary as he leads a walkthrough of HelioVolt’s pilot plant. “We want to scale up as soon as we can.”
It’s not just the how of HelioVolt that makes it unusual in the solar space; it’s also the where. The company isn’t based in southern San Francisco or Boulder, Colo., or the Boston area — the bright green regions that tend to lead the national conversation on clean tech. HelioVolt calls the Texas state capital of Austin home. B.J. Stanbery, the solar veteran who founded HelioVolt in 2001, is a native Texan who got his bachelor’s degree at the University of Texas just down the road from the company’s factory, but he kept his business in Austin for more practical reasons. “The manufacturing skills that workers have here are directly transferable to a thin-film solar company like us,” he says. “And the business culture is attractive here because people are used to taking risks in the energy space.”
Of course, when people think about the energy space in Texas — home to wildcatters and J.R. Ewing of television’s Dallas fame — they probably picture oil rigs and natural gas wells. The current governor of Texas, after all, is the far-right-leaning Rick Perry, who made it known early in his campaign for the Republican presidential nomination that he was a climate-change skeptic. “I do believe that the issue of global warming has been politicized,” Perry told voters in New Hampshire in August. “I think there are a substantial number of scientists who have manipulated data so that they will have dollars rolling into their projects.”
But as politically conservative as Texas tends to be, it’s kept an open mind on renewable energy, which is one reason more wind power has been installed in the state than anywhere else. And within Texas, Austin has always been an outlier: a fairly liberal college town that has managed to marry high tech with hipster culture. Now that’s paying off in the renewable-energy sector, as Austin contends with Silicon Valley as a top clean-tech hub. The city is home to dozens of green start-ups like HelioVolt, many funded by homegrown venture capitalists. Some 15,000 Austin residents are employed in the broader green economy, and the municipal utility, Austin Energy, has pledged to get 35% of its electricity from renewable sources by 2020. Over the past eight years, the number of clean-tech jobs has grown more than twice as fast in the Austin metro area as it has in San Francisco. With its background in information technology, Austin is set to take the lead in one of the most exciting areas in clean tech: the marriage of new energy technology with the Internet. “Austin is already a high-tech city,” says Jose Beceiro, the director of clean energy at the Greater Austin Chamber of Commerce. “Now it’s becoming a clean-tech city.”
Keeping It Weird
For Austin, high tech had to come before clean tech. The city has long been a science-and-technology hub, thanks to the presence of the sprawling main campus of the University of Texas, with a student body of 50,000. In the mid-1980s one of those students was Michael Dell, who founded his eponymous computer company in a University of Texas dorm room before moving Dell to a sprawling campus north of Austin. Around the same time, the federal government and U.S. semi-conductor manufacturers launched a research consortium — based in Austin — called Sematech, pooling public and private investment to compete with Japan, which was threatening to dominate the semiconductor industry.
Sematech and Dell helped create a high-tech boom in Austin through the 1990s, luring tens of thousands of talented engineers who came for the jobs and stayed for the Austin lifestyle — best exemplified by the metastasizing South by Southwest festival, an annual pilgrimage of the hip that brings together music, film and interactive media. “It’s a great place to live, and that matters in this industry,” says Brewster McCracken, the executive director of Pecan Street, a smart-grid research project in Austin.
So as clean tech began to heat up in the early part of the past decade, Austin was a logical place for start-ups and entrepreneurs to set up shop. An experienced technical workforce was already available, ready to shift from manufacturing computer chips to building solar panels. SolarBridge Technologies, which makes microinverters that improve the efficiency of solar modules, spun off from the University of Illinois, but when it came time to scale up, the company picked Austin over other clean-tech hubs like the Bay Area and Boston. “We like the entrepreneurial ecosystem, and there’s just a ton of talent here that you can’t get in Illinois,” says Joe Scarci, SolarBridge’s vice president of marketing. “It’s a great place to recruit.”
