Solar Photovoltaic

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...

Charles W. Thurston Members of the Coalition for Affordable Solar Energy (CASE) railed against the impending "trade war," arguing that the steep price drop in imported Chinese photovoltaic modules was good for "98 percent" of U.S. solar industry jobs. "We are growing U.S. solar jobs and this trade case will undermine all the advances we have made in the U.S. solar industry," said one CASE member. Holding a press conference Thursday morning in Washington after testimony was heard Wednesday by the U.S. International Trade Commission (ITC) about the alleged dumping of Chinese modules in the United States,...

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...

by Debra Fiakas CFA The last post “Meeting Solar Challenge in the Courtroom” discussed how European solar manufacturers are complaining about China’s exports.  A complaint made by industry association EU ProSun charges China manufacturers of solar cells and panels of circumventing Europe’s anti-dumping measures by channeling their products through Malaysia and other intermediaries in order to disguise the China origin.  A report by released last month by IHS (formerly SolarBuzz) makes clear there is much at stake in the solar industry.  IHS forecasts global solar photovoltaic capacity could reach 498 gigawatts by 2019.  That call is...

By Jeff Siegel The road into the digital age has been paved with innovation. Everyday items have been electrified with panels and displays for endless possibilities of interaction. Automobile windscreens, household appliances, even walls and furniture are lighting up all around us, wired with sensors and displays that receive and transmit information. It seems the only surface left to electrify on this road to an everything-digital future is the roadway itself. Some folks believe one day soon, your local road network could be carrying not only the flow of vehicle traffic, but torrential flows of digital data and...

by Sean Kidney Trina’s $150m 3.5% 5yr convertible solar bond In June Chinese solar manufacturer Trina announced the private placement of $150m of 5 year, 3.5% convertible bonds to “institutional investors” (no details provided). Trina weren’t clear how they would use the proceeds, but they are planning to build 400-500MW of solar plants over the rest of this year. Book-runners were Deutsche Bank, Barclays, J.P. Morgan and Goldman Sachs (Asia), with co-manager HSBC. SunPower issues $400m 7yr 0.875% (!) convertible solar bond That same month SunPower announced a private placement of $400 million, 7 year, 0.875% senior convertible bonds. What...

by Debra Fiakas CFA Last week Canadian Solar (CSIQ:  Nasdaq) bagged another solar module supply agreement  -  this time on the home turf of some of its staunches competitors.  Of course, the company has its own manufacturing foothold in China.  Canadian Solar is to supply its solar modules to China Three Gorges New Energy Company to a 100 megawatt solar power project in Guazhou County in Gansu Province.  The modules shipments will be complete by the end of the December 2013, suggesting all the sales will end up recorded yet in the current fiscal year. ...

John Petersen In 2009, the world produced some 13.2 billion metric tons of hydrocarbons, or about 4,200 pounds for every man, woman and child on the planet. Burning those hydrocarbons poured roughly 31.3 billion metric tons of CO2 into our atmosphere. The basic premise of alternative energy is that widespread deployments of wind turbines, solar panels and electric vehicles will slash hydrocarbon consumption, reduce CO2 emissions and give us a cleaner, greener and healthier planet. That premise, however, is fatally flawed because our planet cannot produce enough non-ferrous industrial metals to make a meaningful difference and the prices...

Doug Young After a massive rally over the last year, shares of solar panel makers could be set for a few months of winter following a disappointing earnings announcement from superstar Canadian Solar (Nasdaq: CSIQ) and a debt default from second-tier player Chaori Solar (Shenzhen: 002506). Such a correction was almost inevitable after last year’s huge rally and shouldn’t be cause for concern among long-term buyers of shares in top players like Canadian Solar. But shareholders of second-tier firms like Chaori might think strongly about selling their stock, as these smaller companies could easily end up getting wiped...

Doug Young  Sunset for Suntech. Photo by Tom Konrad As the sun rapidly sets on former solar pioneer Suntech (OTC: STPFQ), I thought I’d take a look at the latest reports that show just how closely the company relied on state support. At the same time, another major development has seen Suntech’s shares finally de-list from New York, where they have traded since its 2005 IPO. The de-listing is something that should have happened long ago, even though investors continued to bet that Beijing would rescue Suntech ever since...

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...

This article is a continuation of my Ten Alternative Energy Speculations for 2008, with picks #8, 9, and10 published last Thursday.  If you haven't already, please read the introduction to that article before buying any of the stock picks that follow.  These companies are likely to be highly volatile, and large positions are not appropriate for many investors.   My least risky picks are part of that same article linked to above; the moderately risky picks are here.  This article contains the most speculative three picks. #3 Nevada Geothermal Power (OTCBB:NGLPF or Toronto:NGP.V) US$1.29 or CAD$1.26 Geothermal first started catching...

For investors excited about Cree's (NASD:CREE) Light-Emitting Diode (LED) business, here's one more piece of good news: The EE Times Reports that the Fraunhofer Institute for Solar Energy Systems (Freiburg, Germany) claims it has achieved a record efficiency for its inverter designed for PV generators, using Cree's SiC transistors. I've previously noted that inverters are a good way to participate in the Solar and Wind power markets without needing to invest in the high priced (or foreign) companies which dominate those markets, and even without this news, Cree is a longtime favorite of this blog.  The stock shot up...

Doug Young Trade War. photo via Bigstock It’s been interesting to watch all the different interpretations coming out of a brief flurry of talks in Europe late last week aimed at settling a trade dispute between the EU and China over Beijing’s support for its solar panel makers. About the only thing that everyone agrees on is that some talks did happen, and that China took the interesting step of letting an industry association rather than government officials handle its side of the negotiations. But after that, no...

Doug Young Solar Lifeline image via Bigstock A new Chinese media report shows that after more than a year of talk, Beijing is finally turning its aggressive talk on solar energy into action by more than doubling its approval of new solar power plants this year. The main question now is: Will any of its struggling solar panel makers survive long enough to enjoy the expected boom in business when some of these new plants start to get built. Of course industry watchers will know the answer is...
