[pagebreak:Can OptiSolar Make Thin-Film Dreams Real?]
A low-key Californiasolarstartup with links to Canada’s oil sands industry is emerging as a dark horse in the increasingly competitive market for thin-film solar cells.
But some observers wonder whether three-year-old OptiSolar can deliver where others have struggled.
OptiSolar, of Hayward, Calif., unveiled plans last week to build a 550-megawatt solar PV park in San Luis Obispo County, Calif. Construction on the massive $1 billion project is expected to begin in 2010, with the company’s silicon-based thin-film panels blanketing about 9.5 square miles of flatlands on the Carissa Plains -- not far from Ausra’s proposed 177-megawatt solar-thermal plant.
Meanwhile, OptiSolar aims to break ground next month on the first of several solar parks it plans to construct in Ontario, Canada. The company has signed 21 contracts with the local power authority to sell more than 200 megawatts of solar electricity into the Ontario grid. The province pays a premium of 42 Canadian cents per kilowatt-hour under its European-style standard offer program.
Peter Carrie, vice president of OptiSolar’s Canadian subsidiary, OptiSolar Farms Canada, says the first 10 megawatts of its largest project -- the 60-megawatt “Solar Sarnia” park -- will be operational by the end of this year.
“Our project management team is already mobilizing,” Carrie said. “We’ll build out the balance in 2009.”
The projects in Ontario and California alone account for more than 700 megawatts of solar capacity, an impressive pipeline for a thin-film startup yet to establish volume manufacturing or an industry track record.
“If they’re developing their own thin-film technology, you might expect that to take more than three years,” said Jenny Chase, lead solar analyst with New Energy Finance. She said producing quality thin-film modules has been the holy grail of the solar industry for 30 years. “It’s not trivial. There are a number of companies that have hit the stage where OptiSolar is right now and haven’t produced enough to build a 550-megawatt project.”
First Solar (NSDQ: FSLR), with its cadmium-telluride thin-film modules, is a standout exception. Even Nanosolar, which has a three-year head start on OptiSolar and has raised $150 million over the past two years, only began production of its copper-indium-gallium-diselenide panels in December.
OptiSolar, however, has a vertically integrated business model that makes it somewhat unique among its peers. Its biggest customer appears to be itself, meaning it can assure access to low-cost modules as it embarks on a plan to construct multi-megawatt solar parks around the world.
Its revenues will come from long-term power-purchase agreements, and any progress in lowering module and installation costs go directly to the bottom line.
The strategy makes it easier for OptiSolar to attract capital for its large solar parks, because it theoretically can guarantee a better return on investment than a company such as SunEdison, which must buy marked-up product from third-party suppliers.
So far, OptiSolar has done a decent job of attracting capital, most of it under the radar. Chase said the company – formerly named Gen 3 Solar Inc. -- has raised $71.7 million in venture capital since December 2006, though some have reported figures as high as $89 million.
Even so, Chase said she suspects the company will run into difficulty supplying its own projects and may need to buy modules from other manufacturers to bridge the gap.
Carrie dismissed the possibility.
“Our plans are to use our own modules for all our projects, including the initial ones,” he said. “You don’t need to speculate about that.”
Initial modules for Ontario will be manufactured out of OptiSolar’s California facility. The company also is constructing a 600,000-square-foot “high-volume” manufacturing plant in Sacramento, Calif., where the county is offering a $20 million economic incentive to make the site more attractive.
[pagebreak:OptiSolar: Continued] The facility, based in a business park that used to be a U.S. Air Force base, will have an annual production capacity of 700 megawatts and is expected to hire 500 employees over the next three years.
It eventually will become the main supplier of modules to its Ontario and California solar projects, said OptiSolar spokesman Jeff Lettes. Hiring already has started, with nine of 33 job postings located in Sacramento.
“Hayward is OptiSolar’s initial manufacturing and R&D facility,” Lettes said. “Both facilities will have the same capacity per product line. Sacramento’s number of product lines will be significantly greater.”
Patent documents show that OptiSolar uses a chemical vapor-deposition process to coat a substrate with a layer of amorphous silicon far thinner than a human hair. The company plans to create a pancake-shaped hydrogen plasma cloud in a special chamber to enhance chemical reactions at lower temperatures, presumably leading to energy savings and reduced cost.
The company says its process uses less than 1 percent of the silicon contained in conventional crystalline cells, and because it doesn’t use exotic materials such as cadmium-telluride, it’s easy to recycle. One job posting for a senior scientist hints that multi-junction thin-film cells could be in the offing.
So what’s the connection to the oil sands? Chief executive Randy Goldstein and executive vice president Phil Rettger, both co-founders of OptiSolar, come from a previous venture in the Alberta oil patch.
The two Americans are co-inventors of a process for upgrading tar-like bitumen into high-quality synthetic crude oil, and in 1999 they founded Calgary, Alberta-based OPTI Canada to apply their technology to oil-sands projects. Goldstein, who declined a request for an interview, continues to serve on the OPTI Canada’s board.
“That team got pretty well connected in the Canadian business community,” said Rick Nathan, managing director of Kensington Capital Partners in Toronto. Last month, Kensington announced that one of its private-equity funds had invested $3 million in OptiSolar, but Nathan said that’s just what was disclosed. “We obviously like the company a lot. Most of the time you don’t want to talk about your investments.”
Toronto-based Gardiner Group Capital and Richardson Ventures of Winnipeg, Manitoba, also are past investors in OPTI Canada that are now heavily backing OptiSolar. Gardiner vice chairman Geoffrey Cumming is chairman of OptiSolar, while Richardson executive Robert Puchniak sits on both OptiSolar’s and OPTI Canada’s boards.
And industry insiders say it’s OptiSolar’s Canadian connection that has allowed the California greentech maverick to fly largely under the radar.
