Solar

John Petersen During the fourteen years that I've lived in Switzerland, the Germans have been the world's staunchest supporters of green power and alternative energy. Their aggressive development of wind power was breathtaking, as was their warm embrace of photovoltaic power. Over the last few weeks, however, there has been an ominous change in the mainstream German media's tone as the political class finally comes to grips with the unpleasant reality that rooftop solar panels are worthless on short, grey winter days and "For weeks now, the 1.1 million solar power systems in Germany have generated almost no...

EMCORE Corp. (EMKR) announced that it has signed a subcontract to participate in the Defense Research Projects Agency (DARPA) Very High Efficiency Solar Cell (VHSEC) program to more than double the efficiency of terrestrial solar cells within the next 50 months. EMCORE's Photovoltaic division was selected by the University of Delaware, the prime contractor for the DARPA VHSEC program, to develop advanced III-V multi-junction solar cells in Phase I of the program effort. In later phases, EMCORE expects to develop a technology roadmap for enabling significantly lower fabrication costs for the very high efficiency solar cells.

The market correction I've been expecting seems to have begun.  If it continues, I will start buying again.  Here are five solar (and solar balance of system) stocks I'd buy at the right price. Tom Konrad, Ph.D., CFA This article continues my Clean Energy Stocks Shopping List series.  So far I've brought you: Five clean transport stocks, I looked at why it makes sense to wait for better prices, Five Energy Efficiency stocks (always my favorite sector), and Five Electric Transmission Stocks. Two Landfill Gas and Three Geothermal Stocks Long-time readers will know that I don't...

The US Congress voted on Monday December 11 to extend, by 1 year, a 30% tax credit for the solar industry. This federal incentive is essential in allowing solar to be competitive with conventional energy sources. How have investors reacted to this announcement so far? Let’s have a quick look at 5 high-profile solar stocks to see whether this news has impacted the trading patterns of solar investors. The stocks are: Suntech Power , Energy Conversion Devices , DayStar Tech , Evergreen Solar , SunPower Corp . ...

Energy Conversion Devices Inc (ENER) announced today that it has signed a two-year distribution agreement with Conergy AG of Germany for 1.5 MW of photovoltaic (PV) products. Conergy AG, a supplier of solar systems based in Hamburg, will distribute UNI-SOLAR(R) products in France, Greece, Spain, and Switzerland through its main subsidiaries.

Tom Konrad, CFA One of the best things about Solar Photovoltaics (PV) is that they can be installed close to load but need not take up open space.  Now public company Envision specializes on solar shading for parking lots that not only produces power, but also shade where it's needed most. I lived in Tucson, Arizona for two years in the early 2000s.  Like everyone who lives in the desert Southwest for any length of time, I became very aware of what would happen if I left my car in an open parking lot for more than...

Garvin Jabusch The hysterics around recent solar industry announcements that in general profit margins are narrowing are, as usual with all things solar recently, completely overblown. "Is This A Death Spiral for Solar Companies?" might be my favorite histrionic headline.

But this is and has always been a standard part of the evolution...

by Clean Energy Intel This past Friday, the 30th September, was the final day for approvals under the Department of Energy's 1705 Loan Guarantee Program. This was of course set up as part of the 2009 stimulus law and extended an existing Energy Department loan guarantee program. Activity at the DoE under the program has also now of course become a highly political issue in the aftermath of the move by Solyndra into Chapter 11 - leaving the program exposed on its $535m loan guarantee, extended to the company in September of 2009. In...

Solarworld AG (SWV.DE) will buy businesses from Shell to take over as the top maker of solar power equipment in the United States. The news prompted a leap in Solarworld shares, already buoyed by President Bush's pledge to promote new technology to make the United States less dependent on imported oil. The agreement covered Shell factories in Germany and the U.S. and sales operations in Germany, Singapore and South Africa. The price of the deal was not released and is still waiting for regulatory approval.

Tom Konrad The 5.7 MW Solar Farm in Salisbury, MA is the largest solar farm in New England. The land under if was purchased by Power REIT (NYSE:PW) in December. Photo source: Power REIT I first wrote about Power REIT’s (NYSE:PW) plans to invest in renewable energy real estate in May 2012.  The intent was to buy the real estate underlying a solar, wind, or other renewable energy project, charging the project owners rent.  This can be done profitably because REITs often have a lower cost of capital...

John Petersen Last week I had the pleasure of participating as a panelist in Infocast’s Storage Week and attending four days of presentations by industry executives, national thought leaders and policymakers. While most of the presentations were too detailed and specific for a blog about energy storage stocks, there were a few high-level discussions that may be interesting to readers and while I'll never qualify as a journalist I can at least share some of the thoughts I jotted down. Storage for Integration of Renewables Two of the most important presentations came from Dr....

Active Power Inc (ACPW) announced that it has received an order for its new CoolAir DC product from one of the leading producers of photovoltaic modules in Europe. CoolAir DC uses thermal energy and compressed air to provide power, can be cycled regularly without a loss in performance and is environmentally friendly. By using solar energy to heat the thermal storage unit (TSU) and compress air in the storage tanks, energy can be captured and used at a later time. The share price of ACPW has recently retested the trendline and I will be adding to...

Spire Corp (SPIR) announced that the Company is using its own SPI-LINE(TM) photovoltaic module production line to fabricate large-format, building-integrated photovoltaic (BIPV) modules for Kyocera Solar, Inc., demonstrating the capabilities of Spire's versatile manufacturing equipment. In 2005, Spire produced BIPV modules for Kyocera's Solar Grove installation in San Diego, California.
