Ed Gunther From Solar Light Flashes: SPI12 Edition Sunny Boy TL-US Inverter SMA Solar Technology AG (ETR:S92) will begin limited shipments of the transformerless Sunny Boy 3000/4000/5000TL-US-22 inverter series for 3 to 5 kiloWatt rated AC power PV systems in 4Q12. The TL-US series has added a unique Emergency Power Supply feature providing daytime power to a dedicated power socket in the event of a grid power outage. The power socket is isolated from the grid during the outage and supplies up to 12 Amps so long as...

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...

Jennifer Runyon Responding to projections that the solar panel module overcapacity will continue for at least another year, solar equipment maker GT Advanced Technologies today announced a restructuring plan. The company will lay off approximately 25 percent of its workforce and consolidate its existing business units into a single Crystal Growth Systems (CGS) group. The company said that when fully implemented, the restructuring would save approximately $13 million in annualized expenses. GT expects to record restructuring charges associated with these actions in the amount of approximately $4.2 million in the December quarter. More details and commentary will be...

By Tim Conneally From a huge crop of Israeli cleantech companies, solar power optimization and management startup SolarEdge has filed for a $125 million initial public offering on the NASDAQ exchange. SolarEdge has been talking about IPO since 2011, but opted instead to work with venture capital through three separate funding rounds. By the time it completed its Series D, SolarEdge had raised a total of $37 million from more than ten venture capital groups. The company's CFO recently told Bloomberg that it was difficult to grow such a large company with only private money. An IPO was...

Michael Smele Solar Home with sunflower photo via Bigstock The Ontario microFIT program was launched in 2009 as part of Ontario’s provincial government’s efforts to increase the production of renewable energy. The program provides participants with the opportunity to develop a “micro” renewable electricity generation project on their privately owned property that uses solar photovoltaic (PV), wind, waterpower, or bioenergy (biogas, biomass, landfill gas). I have asked three families who navigated the process of microFIT solar installations to share their experience by answering some questions. ...

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...

Ucilia Wang The pending sale of bankrupted Q-Cells, once the largest solar cell maker in the world, to Korea-based Hanwha Group is the latest reminder that playing geopolitics in the world of solar will only get harder. The creditors of the German company agreed to the sale with a vote on Wednesday, though the sale still requires regulatory approval before it’s finalized. Hanwha will gain a sterling silicon solar cell maker by buying Q-Cells, which was the reigning cell maker back in 2008, before it ceded the spot thanks to the financial market...

A Conversation with Applied Material’s Solar Head Charlie Gay by Neal Dikeman I had a chance to chat today with Dr. Charlie Gay, the President of Applied Materials' (AMAT) solar division.  You may recall, we broke the story in the blogosphere 5 years ago about Applied’s entry into solar, which was anchored with a highly touted and very aggressive strategy for turnkey large format amorphous silicon and tandem cell plants called SunFab. Charlie reminded me that when they began 5 years ago, they did so along two major thrusts:  The acquisition of Applied Films in...

2016 was a wild year and not just for solar and after decades of reliance on government incentives, subsidies and mandates the global solar industry may be inured to unpredictability but the industry as a whole should be wary of global trends.  Solar PV expert Paula Mints looked at a number of the developments for solar companies in the December edition of  SPV Market Research's Solar Flare.  Adapted for AltEnergyStocks.com, this series of articles is reprinted with permission. The high efficiency monocrystalline cell pioneer and manufacturer SunPower (SPWR) began signaling its competitive struggle in early 2016 and...

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...

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...

by Paula Mints Net metering and interconnection are rights afforded distributed generation (DG) residential and commercial solar system owners through the U.S. Energy Policy Act of 2005. The act required publically owned utilities to offer net metering and left the various policies up to the states to enact. In 2004, before that energy policy was enacted, 39 states had net metering and interconnection standards and policies. At the beginning of 2016, 43 U.S. states and three territories had net metering policies, and four states had policies similar to net metering that the Database of State Incentives for Renewables...

by Paula Mints In terms of the current trade petition and the USITC decision, government interference will not correct an imbalance that is embedded in the industry (globally) particularly when it is put in place by a body that does not understand the nuances of the problem. Despite evidence to the contrary, attorneys and consultants for Suniva/SolarWorld seem to have convinced the USITC that cell manufacturing in the US can be resuscitated and that tariffs and quotas the mechanism that will stimulate manufacturing. In reality, this situation is stimulating uncertainty and doing harm. Table 1: Tariff Recommendations   ...

Magnetek Inc. (MAG) announced that Manhattan's largest functioning Building Integrated Photovoltaic (BIPV) power system recently began harvesting energy from the sun.

Meg Cichon Silevo's Triex Solar Technology In an effort to further streamline its solar business and lower the overall cost of solar energy, SolarCity (SCTY) announced today that it would acquire high-efficiency cell manufacturer Silevo for $200 million. In an effort to scale up the technology, SolarCity plans to construct a 1-GW manufacturing facility located in Buffalo, New York within the next two years. The solar leasing company acquired mounting company Zep Solar in late 2013 in an effort to further vertically integrate its business. Now, chairman Elon...

Doug Young The latest news from Canadian Solar (Nasdaq: CSIQ) and Suntech (NYSE: STP) is casting a shadow over a nascent recovery for the embattled solar sector, as each company struggles to fix its broken finances pummeled by a two-year downturn. Canadian  Solar has announced a plan to raise up to $50 million through a stock sale, while domestic media are reporting that bidding for bankrupt Suntech is moving ahead quickly, indicating the end may be near as an independent company for this former solar high-flyer. All this shows that investors shouldn’t get too bullish on solar companies...
