Solar Photovoltaic

by Tor Valenza a.k.a. “Solar Fred” This article is part of a multi-part series published at Renewable Energy World.  You  can read the other parts here: one, two, three, and four. The Trina Solar (TSL) factory tour and testing facility tour is over. It took perhaps an hour, maybe less. The next stop is a small auditorium where Ben Hill, Trina’s VP of sales, gives us a PowerPoint presentation that includes Trina’s history, market share, company philosophy, and their Formula 1 racing branding initiative. Afterward, Trina’s CEO, Jifan Gao, appears, and we are able to ask him questions through...

by Joseph McCabe, PE More and more solar electric installations are using AC micro inverters and DC to DC optimizer electrical balance of systems (BOS) components. This BOS gear goes directly on the back sides of PV modules providing higher valued electricity than output from the PV cells alone. Two years ago I considered micro inverters as only necessary for lazy designs or bad installation practices.  I’ve changed my attitude towards these approaches after organizing two years of forums as the American Solar Energy Society (ASES) Solar Electric Division Chairperson. These forums brought together experts who compared...

Tom Konrad CFA Last week, the announcement that Principal Solar, Inc. was now available for public trading landed in my inbox.  It's currently trading under the symbol PSWWD.PK but will transition to PSWW.PK on June 23rd.  I went ahead and used the latter in our Solar Stocks list. The press release was remarkable only for the lack of hard facts about the company, focusing instead on the bright future of the solar industry. But experienced investors know that an industry can have a bright future while the individual stocks tank.  A rising tide need not lift all...

Dana Blankenhorn There are a growing number of “solar bears” out there like Jim Chanos, a professional short-seller who is convinced China is poised for a 2008-style crash and who is also selling short stocks like First Solar (FSLR) and Vestas Wind (VWDRY.PK). (What does Chanos like? Would you believe Citibank?) (Picture from Wikipedia.) Personally, I don't know whether Chanos is right about those stocks or not. First Solar is a popular short because it's the best-performing U.S. solar play. Fly high and the assumption is you'll fall fast. But two big mistakes are being made here: ...

Debra Fiakas The chip makers dominate discussion of the solar energy sector.  Nonetheless, a passing comment in a recent blog post introduced me to an interesting company that seems to have been over looked in the solar story  -  Apollo Solar Energy, Inc. (ASOE:  OTC/BB). Apollo produces tellurium, a little known chemical element that looks deceptively like tin.  It is typically a by-product of copper and lead mining operations, but can be found hiding beside gold as well.  While these are very common metals, tellurium is quite rare on earth.  Outer space is another story. Although...

by Joseph McCabe, PE Solar manufacturers are racing to build the next cadmium telluride (CdTe) photovoltaic (PV) factory in the United States. Three major CdTe on glass factories in the US have been recently announced each with a unique starting point. Abound Solar has won a US DOE loan to support a new 640 MW/yr facility in Tipton, Indiana. General Electric (GE) recently announced buying Primestar. They indicate that they will be building the largest PV manufacturing facility in the world. Finally First Solar has announced a 250 MW/yr facility to be built in Mesa City Arizona near...

Green money managers' stock picks after the Japanese nuclear crisis. Even as the nuclear disaster in Japan unfolds, it's clear that the world's energy industry will be forever changed. Russian reactors were never considered safe, but a Japanese to have a nuclear meltdown is an entirely different story. Market Reaction Since Monday, nuclear stocks and ETFs have been plummeting. As of Wednesday night, The Market Vectors Uranium + Nuclear Energy ETF (NYSE:NLR), the iShares S&P Global Nuclear Energy Index (NASD:NUCL), PowerShares Global Nuclear Energy Portfolio ETF (NYSE:PKN), and the Global X Uranium ETF (NYSE:URA) are down...

Dana Blankenhorn Nearly all the big computer companies of the early 1970s have since gone out of business. Remember the BUNCH? Burroughs, Univac, NCR, Control Data, Honeywell (HON)? The first two became Unisys, the last three are still around, but none is a real factor in the computer industry as it exists today. Betting on the BUNCH in 1971 would not leave you in the chips in 2011. Digital Equipment, Data General, Wang, Amdahl? All gone. Along with nearly every company that made PCs in the 1970s save one – Apple. International Business Machines Corp. (IBM) didn't get into the...

Andrew Williams London, UK   On the back of last year's record demand, there are growing concerns that photovoltaic (PV) module supply is set to outstrip demand throughout 2011, leading to significant oversupply in the industry. But are these concerns founded? And if they are, what impact might the oversupply have on the global PV industry? 2011 Forecast According to analysts at UK-based IMS Research, Photovoltaic (PV) module production capacity increased by nearly 70% over the course of 2010, reaching nearly 30 GW by the end of the year.  Looking ahead, IMS anticipates that 35 GW...

Tom Konrad CFA Electric utilities today look a lot like newspapers in 2000: Too much debt in an industry primed for disruption. Speaking at the Economist's Intelligent Infrastructure Conference, Brad Tirpak, Managing Partner at the private investment fund Locke Partners made the case that electric utilities are as woefully unprepared for the coming disruption of cheap, distributed solar power as newspapers were unprepared for the disruption of the Internet in 2000.  He outlined the following parallels: Both had long been considered to be sure-fire businesses with dependable income. Both took advantage of the seemingly...

by Joseph McCabe, PE This past week there was a photovoltaic (PV) workshop that probably wasn't on your radar. It was held at the National Renewable Energy Laboratory (NREL) and is called the PV Module Reliability Workshop (PVMRW). This is where the nerds of the PV industry get together to discuss the factors that influence how long a PV module will last and other factors which might influence the long-term performance of a PV system. It wasn't on your radar because it is not something that influences big business. Or is it? If you track the PV industry...

Dana Blankenhorn Back in December I wrote skeptically of New Energy Technologies Inc., (NENE) whose SolarWindow was written-up here in September, mainly as a result of this press release. The press release drew press coverage, including an October mention by CNBC anchor Erin Burnett. I should add here Ms. Burnett has not done a Maxim cover shoot – the photo by the story is a fake. But is the story a fake? Since the fall NENE has been on a roll, rising in price from about 60 cents to over $1.60. The...

by Debra Fiakas Smilers never lose And frowners never win So let the sun shin in Face it with a grin Open up your heart and let the sun shine in. Age of Aquarius The Fifth Dimension, 1969 Investors have not opened their hearts or pocket books for Entech Solar, Inc. (ENSL:  OTC/BB) despite its products that do indeed let the sun shine in, that is into commercial and industrial buildings through innovative tubular skylights.  Shares of Entech Solar are currently priced below a dime.   Entech has also developed a concentrating solar module marketed...

Analyzing Solar Stocks With False Assumptions Dana Blankenhorn When most people think of solar energy, they see flat panels on a roof. They don't think about thin film. They don't see it. This is one of the many advantages of CIGS  and other thin film solar technologies. So what if its efficiency is half that of a panel? It conforms to the shape of the place where it lays. Thin film can also be productized in ways no panel can. It can be turned into something retailers can sell or bloggers will...

Dana Blankenhorn The lessons of technology investing also apply to solar investing. The decision by Evergreen Solar (ESLR) to move to China has some analysts saying "ha-ha" over solar energy. But in fact it reveals a basic fallacy in the way solar power, and solar power stocks, are analyzed by Wall Street. It's a manufacturing assumption. Solar panels are said to be a manufacturing business. So if prices are going down, that's bad. If governments are no longer seeing solar as just good PR, if they're treating it as a real industry that has to make...

by Joseph McCabe, PE Have you noticed the corporate pitches that compare their products to iPhones or iPads to try and force the feeling that they are "like Apple"? Bill Ford just pitched the Ford electric car in this manner. If Apple is the gold standard, the question becomes, what solar company is closest to being just like Apple? I think the answer is none, at least not yet. The Apple Model Apple has a design culture that attracts design professionals to their product. They also have a completely vertical integrated product where their case, graphical...
