In Richmond, California, there are low-tech robots installing and maintaining large-scale solar farms, at least a start-up company, known as Alion Energy, believes so. Working in near secrecy until recently, the company is ready to use its machines in three projects in the next few months in California, Saudi Arabia, and China. If all goes well, executives expect that they can help bring the price of solar electricity into line with that of natural gas by cutting the cost of building and maintaining large solar installations.
In recent years, the solar industry has wrung enormous costs from developing farms, largely through reducing the price of solar panels more than 70% since 2008. But with prices about as low as manufacturers say they can go, the industry is turning its attention to finding savings in other areas.
"We've been in this mode for the past decade in the industry of really just focusing on module costs because they used to be such a big portion of system costs," said Arno Harris, chief executive of Recurrent Energy, a solar farm developer, and chairman of the board of the Solar Energy Industries Association. Now, Mr. Harris said, "Eliminating the physical plant costs is a major area of focus through eliminating materials and eliminating labor."
