Tesla Inc. is starting production of the cells for its solar roof tiles at its factory in Buffalo, New York.
The company has already begun installing its solar roofs, which look like regular roofs but are made of glass tiles. But until now, it has been making them on a small scale near its vehicle factory in Fremont, California.
Tesla’s Chief Technical Officer, JB Straubel, says the company now has several hundred workers and machinery installed in its 1.2 million-square-foot factory in Buffalo.
“By the end of this year we will have the ramp-up of solar roof modules started in a substantial way,” Straubel told The Associated Press Thursday. “This is an interim milestone that we’re pretty proud of.”
The Buffalo plant was originally begun by Silevo, a solar panel startup, on the site of an old steel mill. Solar panel maker SolarCity Corp. bought Silevo in 2014. Then Tesla acquired SolarCity for around $2 billion late last year.
SolarCity was run by cousins of Tesla CEO Elon Musk, who sat on SolarCity’s board.
“This factory, and the opportunity to build solar modules and cells in the U.S., was part of why this project made sense,” Straubel said.
Tesla’s partner, Panasonic Corp., will make the photovoltaic cells, which look similar to computer chips. Tesla workers will combine the cells into modules that fit into the roof tiles. The tiles will eventually be made in Buffalo as well, along with more traditional solar panels. Panasonic is also working with Tesla at its Gigafactory battery plant in Nevada.
Straubel says Tesla eventually hopes to reach 2 gigawatts of cell production annually at the Buffalo plant. That’s higher than its initial target of 1 gigawatt by 2019. Straubel said Tesla has been working on making the factory more efficient.
One gigawatt is equivalent to the annual output of a large nuclear or coal-fired power plant, Straubel said, “so it’s like we’re eliminating one of those every single year.”
Straubel wouldn’t say how many customers have ordered solar roof tiles, but said demand is strong and it will take Tesla through the end of next year to meet its current orders. Both he and Musk have had the tiles installed on their roofs.
Tesla shares were up less than 1 percent to $355.65 in afternoon trading.

A fossil found in northeastern Nevada shows a newly discovered fish species that scientists believe looked, and ate, like a shark.
The fossil is what remains of a bony, sharp-toothed fish that would have been about six-feet-long (1.83 meters) with long jaws and layers of sharp teeth.
The type of jaw and teeth on the fish suggest it would have chomped down on its prey before swallowing it whole, like a shark, the Reno Gazette-Journal reported.
“The surprising find from Elko County in northeastern Nevada is one of the most completely preserved vertebrate remains from this time-period ever discovered in the United States,” said Carlo Romano of the University of Zurich, lead author of a Journal of Paleontology article about the find.
The fish, which researchers called Birgeria americana, predates Nevada’s most famous fossil, the Ichthyosaur, by more than 30 million years. The Ichthyosaur was a 55-foot-long (16.76 meters) reptile. One of the largest concentrations of Ichthyosaur fossils was found near Berlin, Nevada. The find led to the Ichthyosaur becoming Nevada’s state fossil.

The Birgeria americana fossil finding is important because it sheds light on how quickly large, predator species evolved following the Earth’s third mass extinction that preceded the Triassic period about 250 million years ago.
The evidence shows the fish was alive and well about 1 million years after mass extinction 66 million years ago wiped out an estimated 90 percent of marine species.
It also shows a large fish was surviving in water previously thought to be too warm to support such life.
At the time, water near the equator, which is where land that became Nevada was positioned about 250 million years ago, could have been warmer than 96 degrees. “The eggs of today’s bony fish can no longer develop normally” at such a high temperature, researcher said.
Researchers learned of the fossil about five years ago after fossil collector Jim Jenks of West Jordan, Utah, stumbled upon it near Winecup Ranch north of Wells.
“It was just a very lucky find,” said Jenks, who was credited among the paper’s authors. “I happen to notice the teeth glinting in the sun. That is what caught my attention.”
Jenks turned the fish over to the New Mexico Museum of Natural History and Science, which has a large collection of fossils and connections with leading researchers.
