A Chinese solar giant goes bankrupt, and why that's a good thing

Once the world's largest solar panel maker, Suntech Power, has finally been forced into bankruptcy. The company has been running out of cash for months, defaulted on a loan payment recently, and has now become the biggest casualty yet of the coming consolidation of the global solar industry.

This week eight Chinese banks asked a court to find Suntech subsidiary Wuxi Suntech insolvent and to allow it to begin restructuring. Suntech responded to the court and said it would not object. The New York Times reported that the bankruptcy is "expected to lead to a takeover of the Wuxi operations by Wuxi Guolian, a financial conglomerate controlled by the city government of Wuxi."

The solar market has seen an oversupply of solar panels and plummeting prices for those panels for over two years now. Two thirds of solar cells are made in China, where the Chinese government has given Chinese solar makers access to large low cost loans. The oversupply and drop in prices has led to huge solar manufacturers like Q-Cells to startups like Solyndra and Abound Solar to file for bankruptcy.

It's an American right to have solar

Suntech solar panels

Suntech may be the largest to date, but it won't be the last solar maker to crash. As MIT Tech Review put it earlier this week: "hundreds of solar companies need to fail to help bring the supply of solar panels back in line with demand."

The weeding-out process will help slow the fall in solar panel prices and allow demand to rise back up again. Down the road the re-balancing will enable these companies to continue to invest in more efficient cells and new innovations, which will bring down the cost of solar through technology even more. Another 180 solar panel makers could reportedly disappear by 2015 due to consolidation.

At the same time, Suntech's woes partly come from a financial scandal. The company got in trouble with a fund it controlled that financed solar power plant development in Europe.

Of course, it's not all positive that Suntech has declared bankruptcy. As Ucilia Wang wrote for us last week:

The drama presents an ugly turn for a company that was solid and took technology and market risks to grow. . . Chinese companies in general had been known more as mass producers rather than innovators. . . Suntech's decline also leaves a depressing note in the efforts by the federal and local governments to expand solar manufacturing in the U.S.

The demise of yet another thin film solar maker

The lights are apparently out for yet another thin film solar startup. Global Solar Energy, which was building a business around flexible solar panels, is laying off nearly all of its employees and stopping its manufacturing operation, according to Inside Tucson Business.

The Arizona-based company developed ultra-thin solar panels using the materials copper, indium, gallium and selenium (CIGS) to convert sunlight into electricity. Venture-backed Global Solar initially sold strings of CIGS solar cells to companies that would then assemble those strings into panels. Around 2009, the company said it would focus on making flexible solar panels that forgo the use of glass as a protective cover.

Flexible panels could be a good fit for roofs that can't bear heavy weight, or they could be shaped to resemble - or become embedded in - roofing materials. But foregoing the use of glass meant Global Solar had to find another way to protect the CIGS from its chief enemy: moisture. Companies such as 3M in recent years have rolled out protective films for moisture-sensitive solar cells, but those encapsulants tend to be expensive. A Global Solar executive told me last year that the company had found a good barrier film for its CIGS cells, though he declined to divulge its cost or maker.

Global Solar Takes World's Largest CIGS Project LiveGlobal Solar's star seemed to be rising when it started to work with Dow Chemical to create roofing shingles with its CIGS cells inside. Partnering with a large company meant Global Solar could lean on Dow to help promote its technology. But Dow delayed the launch of roofing shingles, especially given the home construction market was in poor health following the mortgage crisis. Dow finally launched the solar shingle product about a year ago in Colorado. It then began selling them in California and Texas earlier this year.

Global Solar had factories in Tucson and Germany. By Arizona law the company had to notify the state when it was planning any meaningful layoffs. It filed a notice in July about letting go nearly 40 employees. A Global Solar employee told Inside Tucson Business that the company was laying off about 95.

Global Solar appears to be a casualty of an imbalance of supply and demand that has persisted for two years and knocked out dozens of solar manufacturers worldwide. Major solar panel makers, including Suntech Power, First Solar and SunPower, all have shuttered production lines and posted losses as a result. Suntech recently announced its plan to scale back production and lay off about 50 employees at its Arizona factory.

Startups have had a harder time toughening it out because they typically lack the financial strength of their larger rivals. Most often times they need to be in an expansion mode - to build factories and line up customers - in order to move technology out of the labs and into the marketplace. Doing so when the market is experiencing a glut of solar panels simply lowers the startups' survival rates. Solyndra, which also made CIGS solar panels, suffered a high-profile death last year when it was ramping up production and realizing it couldn't compete against companies that were able to sell solar panels far more cheaply.

SunPower pulls back on cell and panel production

The world simply has too many solar panels and not enough buyers. This imbalance already has forced many manufacturers out of business and some to make a huge cut in production. That’s what SunPower said on Tuesday it will do at its solar cell and panel factories Philippines.

The San Jose company says it will suspend production at six of the 12 production lines at Fab 2 for solar cells and 20 percent of the solar panel production in the southeast Asian country. SunPower also will cut about 900 employees, most of them located in the Philippines.

SunPower’s CEO, Tom Werner, issued this statement:

“Industry conditions continue to be challenging and while it is never an easy decision to reduce positions, we must make prudent decisions to effectively compete in an industry with significant overcapacity. Additionally, we’ll further our efforts to reduce costs and improve operational efficiencies.”

In April this year, SunPower announced it would shut down another solar cell factory, called Fab 1, in the Philippines. The goal was the same: to reduce costs so that it could sell its solar panels at more competitive prices. SunPower makes the most efficient silicon solar panels on the market, but its special technology also is more expensive. Its strategy has been to charge higher prices for the more efficient solar panels. But this strategy doesn’t work so well when there is a big oversupply problem.

Its main rivals, many of them in China, have been selling their less efficient solar panels at far lower prices. The pricing battle partly contributed to a trade complaint against Chinese solar cell makers, and the U.S. Department of Commerce decided last week to impose tariffs on imported silicon solar cells from China.

The tariffs aren’t likely to stop solar panel prices from falling, however. Chinese companies can skirt the penalties by buying solar cells from countries such as Taiwan and assembling them into panels in China. This approach will still increase their production costs, but not nearly at the levels of the tariffs.

SunPower sold a majority stake to French oil giant Total last year in order to gain financial help. SunPower said its 2012 sales forecast remains unchanged, and it will provide more details about its cost-reduction plans when it discusses its third-quarter earnings on Nov. 1.

SunPower isn’t alone in idling production lines and laying off a huge number of employees. First Solar has been doing that. Some veterans in the industry, such as Q-Cells in Germany, went bankrupt or have been sold. Many startups that tried to scale up production in the past two years failed because they couldn’t reduce their manufacturing costs fast enough. Solyndra and Abound Solar are two examples. Others, such as MiaSole, got scooped up on the cheap by conglomerates looking to add a diverse set of solar technologies and services in their portfolios.

A startup aims to crank up solar power with efficient materials

Raising money for solar technology manufacturing is tough these days. But a startup called Malachite Technologies hopes to break through with an idea to design equipment that can make a solar cell using super efficient semiconductor materials that can boost the solar energy generation of a panel.

The company pitched a hybrid solar cell concept and at the western regional Cleantech Open event last Friday (winners are announced today), and won over judges in the renewable energy category. The Cleantech Open will hold its national competition in San Jose next month.

The ultra efficient semiconductor materials are in the III-V family, and each III-V cell will sit on top of a silicon cell. Silicon is found in most of the solar cells on the market today, and the most efficient among them, made by SunPower, can convert 24 percent of the sunlight into electricity.

Malachite plans to stack a silicon layer with a gallium-arsenide layer to create a cell that should theoretically be able to achieve 38 percent efficiency, said Robert Weiss of Malachite during the pitch to the judges. Weiss was the former CTO of DayStar Technologies, which makes ultra thin solar panels using copper-indium-gallium-selenide (CIGS).

The III-V cells are less common because their materials and manufacturing process are more expensive. The cells are usually made with a combination of materials such as indium, gallium, germanium and arsenic. These cells are typically found in solar panels that are equipped with lenses to concentrate sunlight onto the cells to boost their energy production. Using the optical booster means the cells themselves could be far smaller, which then reduces the overall equipment and production cost. The most efficient III-V cell, made in the lab and not subject to any concentration, has achieved nearly 30 percent efficiency.

As with many solar cell technologies, the scientific concept Weiss presented isn’t new. The big challenge is to design the process and equipment to not only produce the desired efficient cells but to also produce them in large quantities at low costs. That last part is what has stumbled many solar technology startups such as the now bankrupted Solyndra and Abound Solar over the past year, especially when they were trying to scale up production at a time when there was a bumper crop of solar panels in the market and much larger rivals were able to cut prices and take losses.

Not a cell maker

Malachite doesn’t want to sell solar cells. Instead, it wants to sell the factory equipment for making those cells, perhaps to silicon solar cell makers. The III-V cells usually are made in a process called metal organic chemical vapor deposition (MOCVD), which is expensive and slow. Weiss proposes to use the physical vapor deposition (PVD) process, or sputtering, that knocks loose atoms from semiconductor materials and attach them to a substrate to form a cell. PVD has been used for making CIGS thin films.

Weiss wants to raise up to $2 million to engineer and show a workable cell design. After that, the startup will likely need $10 million to assemble the equipment to complete a prototype cell. Another $30 million should enable Malachite to deliver beta equipment to customers for testing, Weiss said.

Catching investors’ interest will be difficult these days. Many solar cell and panel makers have built up huge factories, some at gigawatt-scale, only to find that demand isn’t there yet. Some of the top 10 solar manufacturers, including Suntech Power and First Solar, have scaled back production or postponed factory expansion plans. Many have filed for bankruptcy, including veterans such as Q-Cells, which is being sold to Korea-based Hanwha Group.

GTM Research released a report on Tuesday that is projecting that 180 solar panel makers will disappear all together or get bought by 2015, and nearly half of them will close factories in places with high manufacturing costs, such as the U.S., Europe and Canada.
