Solar Power’s “Nasty Little Secret” Isn’t Nasty or Secret

The charges leveled by a solar industry insider recently were deadly serious.

“Solar panels do not work that well….and few know it,” revealed Ray Burgess, president and CEO of Solar Power Technologies. Writing in AOL Energy on October 7, Burgess appeared to be a reluctant or even heroic truth-teller, airing the solar industry’s dirty laundry with the best of intentions. (Several times while reading the piece, Jerry McGuire’s Mission Statement came to mind.)

Burgess wrote that “if we who love solar and alternative energy do not put our house in order, those who believe solar is some kind of government-funded shell-game will do it for us. This would be a disaster for our country.”

In other words, Burgess is not just a whistle blower, but a patriot.

Using anecdotes and scientific data, Burgess walks readers through the solar industry’s dismal state of affairs, which can be summed up simply: Photovoltaic panels are crap. They fall apart quickly on their own. Their electrical output is subject to “dozens and dozens” of threats — from bullets to golf balls. (Wait — what about meteorites and chunks of blue ice?) One of his listed threats, dust, is a real concern. But here Burgess establishes a leitmotif for his solar indictment, blowing problems far out of proportion.

“In 2009,” Burgess writes in one anecdote, “Google found that after it cleaned its panels, energy doubled.”

Here’s what the Red, White and Blue Whistle Blower left out.

“We have two different sets of solar panels on our [MountainView, California] campus,” Google explained in its official blog,”completely flat ones installed on carports, and rooftop ones that are tilted.” Washing doubled the output of the flat-mounted panels.

But, the blog continued, “The rooftop solar panels are a different story. Our data indicates that rain does a sufficient job of cleaning the tilted solar panels….So for now, we’ll let Mother Nature take care of cleaning our rooftop panels.”

Another fact Burgess fails to mention is that nearly all solar installations are tilted, primarily to capture the most sunlight. Owners of solar panels do need to maintain them for peak performance, but that’s hardly a nasty little secret.

Burgess also calls claims that solar panels lose their ability to convert sunlight into electricity at just 0.5 percent per year, “bogus.” According to the prestigious National Renewable Energy Laboratory (NREL), Burgess writes, panels degrade “as much as 4.5% a year. Or more.”

At this point, you don’t need to be an expert to be suspicious, just a competent reader. The phrase “as much as” refers to an upper limit. Tacking on the words “or more” attempts to recast the ceiling as a floor.

In fact, as reporter Anne Paine points out in a balanced story on how solar panels perform over time, NREL found that most panels studied over the last 40 years degraded at a rate under 1% per year.

Questioned by Paine in The Tennessean, Burgess back-peddled, admitting that his 4.5 percent claim was “an extreme case.”

The rest of Burgess’ Jeremiad continues in this same vein, citing imaginary problems or inflating real ones to absurd proportions.

Burgess’ motive for airing what he called solar’s “nasty little secret” may have something to do with his niche within the industry he claims to love. His company doesn’t actually make solar panels — it makes devices that monitor the performance of solar panels. Just what you’d need if you wanted to know, say, how fast your panels were degrading.

If this were simply about a company cranking up the fear factor to sell more widgets, it wouldn’t be worth writing about. Advertisers prey on consumer fears all the time. But, timing is key here. According to a study released this week, the number of jobs in the solar industry grew at a rate of 6.8 percent in the passed year — almost ten times faster than the U.S. economy as a whole. Compare that to employment in the fossil fuels industry, which is expected to shrink by 2 percent in the coming year.

The words of the Saudi oil minister in 1976 could come today from Big Coal and Big Oil: “The big powers are seriously trying to find alternatives to oil by seeking to draw energy from the sun or water. We hope to God they will not succeed quickly because our position in that case will be painful.”

In the recent collapse of solar manufacturer Solyndra, the dirty energy industries see an opening to stave off the pain of competition from renewable, clean energy. They, and the politicians they  support, are hoping to use the Solyndra failure as a wedge to bring down the entire renewable energy tree — and dispose of the current administration which has done a lot to support alternative energy. (Not enough, perhaps, but a lot.)

The Burgess piece provides the kind of ammunition the fossil fuels industry wants, even if the charges aren’t accurate. Once these horror stories are published, they bounce around the Internet and are repeated until no one knows whether the figures quoted are right. It’s already happening. The article was the basis for a piece that ran in a Charleston Daily Mail (W.VA) blog under the headline, “Expert: Solar panels don’t work well.

Whistle blowers can play a critical role in keeping businesses and governments honest. Sometimes, however, they just blow.

Solar Power | Coming on Strong

Even before Japan’s nuclear nightmare began, the solar power market in the U.S. and abroad were set for another year of remarkable growth, according to several analysts and industry leaders.

One such individual suggested recently that the only close analogy to the coming surge in solar photovoltaic panels (PV) is Apple, Inc.’s performance last year after the iPad took off.

Excitement over solar’s continuing growth-spurt served as background music for a PV industry gathering that ended in Philadelphia last night.

“The solar industry is the fastest growing industry in America!” Rhone Resch, president and CEO of the Solar Energy Industries Association (SEIA), told some 3,000 conference-goers. “We are growing faster than wind energy, faster than telecommunications, and, thank goodness, we are even growing faster than the mortgage foreclosure industry!”

Bob Gibson, VP for market intelligence at the Solar Electric Power Association (SEPA), pointed to one large source of growth for the industry: utilities expanding their energy mix to include solar.

“In very real and growing ways,” said Gibson, “electric utilities … across the country are part of the renewable energy industry, and in particular, the business of building and providing solar power.”

The Numbers

And there are a lot of data to support such enthusiasm.

While the U.S. GDP grew just 2.8% in 2010, the domestic solar market jumped by 67% last year, according to GTM Research.

The GTM/SEIA U.S. Solar Market Insight, 2010 Year in Review holds a lot more good new for the solar sector. For example, grid-connected PV installations rose to 878 MW (megawatts) last year, a 102% increase over 2009.

While the pattern of growth was widespread, ten states account for over 60% of all new installations (see the breakdown in figure 1).

Notice that California grabbed the lion’s share, at 35% of the total. And that was before the state legislature passed a bill (on March 30) mandating that utilities obtain one-third of their electricity from renewable energy sources, including solar power, by the end of 2020.

(To be fair, former CA Governator, Arnold Schwarzenegger, had issued an executive order calling for the same goal, in 2009. That EO, however, could have been overturned by another governor and so didn’t provide the level of predictability utilities need to make significant investments in solar– a stability they now have.)

Other positive indicators cited in the GTM report:

  • A marked increase in U.S. PV component manufacturing: 97% for wafers, 81% for silicon cells, and 62% for PV modules.
  • The largest Concentrating Solar Power (CSP) plant built in two decades went online. (Martin Next Generation Solar Energy Center, 75-MW, in southeastern Florida.
  • The installation of nearly 29,500 solar pool heating systems and 35,500 hot water systems.

DOE: SunShot Initiative to Cut Cost of Solar PV Systems by 75%

Secretary of Energy Steven Chu

Rhone Resch listened carefully Friday as Secretary of Energy Steven Chu announced “SunShot,” a new federal initiative with the ambitious goal of reducing the total cost of photovoltaic (PV) solar power systems by 75 percent by the end of the decade.

Resch liked what he heard.

As president and CEO of the nation’s largest solar trade organization, the Solar Energy Industries Association (SEIA), Resch calls the initiative “significant because DOE is focusing on driving down the cost of the other components of a solar system” — not just the cost of PV cells. In a statement following Chu’s announcement, Resch said that the cost of PV panels has been cut in half in the last two years, so focusing on other aspects is the right approach.

The $27 million SunShot initiative focuses on four areas:

  • Increasing the efficiency of the solar manufacturing process
  • Optimizing the performance of the installation
  • Improving solar PV technologies
  • Streamlining the permitting process

Not to minimize the importance of the first three areas on the list, but it is the fourth item — reducing solar “soft costs” — that is bound to please the solar industry.
