By 2015, two-thirds of the U.S. will have achieved grid parity, the
point at which electricity generated from photovoltaics is equal in
cost or less expensive than grid power, an analyst said Monday (July
13). At that point, solar power will be no more than 5 cents per
kilowatt hour more expensive than grid power for 99 percent of the
country, according to Travis Bradford, founder and president of the
non-profit research group The Prometheus Institute for Sustainable
Speaking to a packed ballroom at the Intersolar North America event
here, Bradford said the combination of falling photovoltaic system
costs and larger government subsidies juxtaposed against the rising
cost of grid electricity means that the U.S. is “rapidly approaching
But Bradford added that there is skepticism that grid parity is
within reach, especially among those who last looked at photovoltaic
system costs back in 2007, when they were significantly higher. “I’m
not sure that a lot of people believe it,” Bradford said.
Others have predicted previously that a majority of the U.S. would
achieve grid parity by 2015. But Bradford’s assertion that 99 percent
of the country could access solar generated power for no more than 5
cents/kWH more than grid power appears to be a first.
Andrew Beebe, managing director of energy solutions at SunTech America, the U.S. subsidiary of China’s
said it was the first time he had seen such an aggressive prediction.
“It’s great, assuming that it is true,” Beebe said. He added that
research from The Prometheus Institute is generally very accurate.
Getting solar power within 5 cents/kWH of grid generated power would be
significant because it would close the economic gap and allow more
environmentally conscious consumers and organizations to switch to
solar power without feeling the financial pain, said Shyam Mehta, a
senior analyst with GTM Research.
“The economics need to get closer so that the externalities can come
into play,” Mehta said. “They won’t come into play if the economics
aren’t close enough.”
Bradford said solar in the U.S. will get a big boost from economic
subsidies as part of the financial rescue package enacted by the U.S.
last November and from the huge fiscal stimulus pushed through earlier
this year. At the same time, he said, government incentives to push
solar in European countries like Spain and Germany are, at least
temporarily, on the decline. As a result, Bradford said, the U.S. has a
shot to become the biggest market for photovoltaics and one of the
largest producers over the next few years.
“The U.S. is going to be an extraordinary market,” Bradford said.
Later, he added, “If this [solar] industry is going to be a revolution,
I think now is the time.”
In a panel discussion following Bradford’s presentation, Julie Blunden,
vice president of public policy and corporate communications at
SunPower Corp., said the growth of the solar industry could be slowed
by political forces as the solar industry attempts to enter the power
