Solar Photovoltaic

by Tor Valenza a.k.a. “Solar Fred” It’s official. With the bankruptcies of Solyndra and Evergreen, two solar panel companies with unique premium solar PV technologies, the Market with a capital M hath spoken: “Solar PV manufacturers, we, the purchasers of solar PV, do hereby care more about price than any fancy innovation. Just give us the best quality panel for the lowest $/watt, thank you very much.” String ribbon doesn’t matter. Cylindrical CIGS film doesn’t matter. Even made in America doesn’t matter unless it's at a competitive price. Apparently, all the Market wants to know are the...

Doug Young I wrote earlier this week about troublesome signs for the solar panel sector’s fledgling recovery after a revenue warning from Trina (NYSE: TSL), and now we’re seeing another worrisome signal with news that Yingli (NYSE: YGE) is launching a new fund to build solar power plants. This kind of scheme looks eerily similar to one that kicked off the downfall of former industry leader Suntech (NYSE: STPFQ), though there are also a few differences. Still, Yingli’s latest move signals that the industry may not have learned its lesson from the Suntech debacle. Yingli’s decision...

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...

Doug Young Canadian Solar (Nasdaq: CSIQ) has joined a growing field of Chinese solar panel makers entering the risky business of speculative development in China, with its launch of a new locally-based fund for solar power construction. The move follows the establishment of self-financed vehicles for similar speculative construction by rivals Trina (NYSE: TSL), Yingli (NYSE: YGE) and wind power equipment maker Ming Yang (NYSE: MY), as they try to create more demand for their products. Under such a strategy, solar panel makers typically provide some or all of...

Doug Young  More bright signs are emerging in the solar panel sector with word of 2 major new tie-ups, one involving ReneSola (NYSE: SOL) in Japan and the other Yingli (NYSE: YGE) in China. In the first, ReneSola has signed a massive deal to sell panels to a Japanese solar power plant developer. The latter case looks similar, with Yingli in its own deal for a major joint venture to co-develop new solar power plants with one of China’s top nuclear power companies. The deals point to the huge potential from the China and Japan markets for solar...

Doug Young President Obama's election victory has dominated US headlines over the last 2 days, but Washington showed it was still hard at work with news that the Commerce Department has finalized punitive anti-dumping tariffs against Chinese solar panel makers. In a way, this kind of quiet ending seems appropriate for a drawn-out process that began more than a year ago with a Congressional probe into a bankrupt US solar firm. With this trade issue now resolved, China, which produces more than half of the world's solar panels, can now focus on simply saving an industry that is...

Paul Denholm, a Senior Analyst at the National Renewable Energy Lab (NREL), sees an upcoming struggle between renewable sources of electricity such as photovoltaics (PV) and wind with low-carbon baseload alternatives for space on the low carbon grid of the future.  These baseload alternatives are nuclear and Internal Gasification Combined Cycle coal plants with Carbon Capture and Sequestration (IGCC w/ CCS, refereed to by advocates as "Clean Coal). This may come as a shock to advocates of the idea that Global Warming is such a big problem that we will need all forms of low carbon electricity, because the...

by Paula Mints   Few people understand the time, money and effort required to develop and manufacture high quality solar technologies.  We can blame this fact on a reliance on press releases for news about the solar industry. Manufacturers drive these misunderstanding by not properly explaining that champion results are not analogous to or in many cases near commercial viability. The PERC, passivated emitter rear contact solar cell, now gaining market traction began its long trudge to commercial competitiveness in the mid-1980s. When manufacturers announce results without fully ex-plaining these results the effect is misleading and also...

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...

To win the U.S. solar installation game, SolarCity (SCTY) continues to go vertical and thin its margin stack... so what'll be next? James Montgomery SolarCity (SCTY) is acquiring Zep Solar and its rackless mounting design in a $158 million stock deal, illustrating the growing importance of improving costs and complexity in residential solar. Much of the cost-cutting in solar PV has been shouldered by the upstream manufacturing side, but half the costs or more in a residential solar PV system come from the softer side, and they'll have to keep coming down dramatically to support widespread deployment of...

By Beate Sonerud SolarCity (NASD:SCTY) is issuing US$200m of asset-linked retail bonds, with maturities ranging from 1-7 years and interest rates from 2-4%. Wells Fargo is the banking partner. While the bonds are registered,SolarCity expects the bonds to be buy and hold, and not traded in the secondary markets. The bond is issued for small-scale investors, with investment starting at US$1000, giving this bond issuance a crowdfunding aspect. Choosing such a different structure allows SolarCity to diversify their investor base – the company stresses that small-scale investors are a complement, not substitute, for large-scale institutional investors. While...

Liz Nelson The largest thin-film panel manufacturer in the world has an optimistic view of the immediate future for renewable energy demands. First Solar (FSLR) had an impressive charge for several years until the final quarter of 2008 when the stock value of the photovoltaic manufacturer began to plummet. Over the course of four years, the stock had dropped from approximately $311 per share to a dismal $11.43 nearing the end of the second quarter in 2012. At the beginning of April of 2013, the stock had nearly tripled in value and continues to gain momentum. The beginning of...

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 As a rule "penny stocks," public companies routinely selling for less than $1 a share, and sometimes just a few pennies, make me nervous. While the intent is laudable – to give small investors a chance to bet on long shots just like the boys on Sand Hill Road  – the result has always looked like a rigged casino. Because of its low capitalization and small float it's easy to “pump and dump” a penny stock, boosting its value with some publicity, then selling it short. And if the deal were worthwhile, why isn't the smart...

by Joseph McCabe, PE In our last article  "Metrics for Thin Film Solar CIGS Company Comparisons," we alluded to finer system level details in the comparison of photovoltaic (PV) technologies and promised this follow up article on the subject. System level details begin with the PV modules themselves. Band gap, temperature corrections  and fill factor are just some of the finer technology details, all slightly related in that they can produce system performance differences when comparing similar PV technologies. Band gap is the quantum-level point where the PV technology absorbs photons. Think of the...
