  • Solar soars past wind in Europe: Is this a new trend?

    Editors' Blog | By Mark Osborne - 31 January 2011, 17:13 | 1

    New wind power capacity installed in the EU last year reached 9.3GW, according to the European Wind Energy Association (EWEA). Even though the solar sector seems sluggish in declaring its installed figures, just the official forecast numbers coming from Germany, Italy, France and Spain alone would result in over 10GW of PV installations in 2010.

  • Dodgy times: ‘Buy American’ report reminds readers not to believe all the solar PV news you see

    Chip Shots Blog | By Tom Cheyney - 27 January 2011, 06:01

    Since President Barack Obama signed HR 6523, the “Ike Skelton National Defense Authorization Act for Fiscal Year 2011”  on Jan. 7, there has been a wave of reporting and analysis about the “Buy American” provisions in Section 846 of the act and what they might mean for U.S. solar manufacturers as well as foreign PV companies with U.S. production facilities. The quality of the media coverage has ranged from accurate and insightful to abysmal and confused, but one particular, widely aggregated piece deserves a closer look because of the plethora of misinformation it contains in a short space.

  • Italian PV installations turn heads

    Editors' Blog | By Mark Osborne - 26 January 2011, 20:13 | 3

    Much debate and head scratching followed the announcement from Italy’s energy manager GSE over PV installation figures that seemed significantly higher than industry observers had previously forecasted, not least among the PV-Tech editorial team.

  • Here comes another big year

    Guest Blog | By Mark Bachman - 25 January 2011, 11:31

    A well-telegraphed joint press conference between the BSW (Germany’s solar industry) and Germany’s Environment Minister outlined potential midyear (July 1) feed-in tariff cuts for the German solar industry. Bulls and bears will have equal amounts to hang their hats on, but Germany’s ultimate goal of reducing excess project returns while still stimulating demand to achieve installation goals looks quite possible.

  • Solar short takes: Suniva implements ion implantation, First Solar turns knobs, CIGS gets purified

    Chip Shots Blog | By Tom Cheyney - 19 January 2011, 00:56

    With the New Year gaining inexorable momentum and the Chinese Lunar Spring Festival right around the corner, it’s time for the first Solar Short Takes blog of 2011. This edition features news of U.S. cellmaker Suniva and its ground-breaking use of ion implantation in volume production of high-efficiency solar cells, a few tidbits about First Solar’s engineering focus areas and view of CIGS, an enabling material purification approach for CIGS, calls for papers from two of the leading PV conferences, and a few thoughts on a certain Korean-Chinese company’s (re)branding.

  • Eye on Stion, Part II: Getting a taste of tandem-junction CIGS PV layer cake

    Chip Shots Blog | By Tom Cheyney - 13 January 2011, 04:47

    “Making CIGS is kind of like baking a cake; they all have flour, eggs, and milk. But we don’t tell you everything in the recipe,” quipped Stion CEO Chet Farris. In his company’s case, the cinnamon and nutmeg can be found in the constituent ratios, molybdenum back-contact secret ingredients, a nontraditional approach to depositing the transparent conductive oxide, and other ways of sweetening its copper-indium-gallium-sulfur-(di)selenide thin-film photovoltaic confection. The pastry analogy doesn’t end there: the upstart’s roadmap calls for a tandem-junction CIGSSe device, a veritable high-efficiency layer cake.

  • The (r)evolution of PV power plant sizes

    Guest Blog | By Edwin Koot - 10 January 2011, 17:01 | 1

    In this guest blog, Edwin Koot, founder of, discusses the growing trend of the ever-increasing size of utility-scale PV power plants and the implications facing the industry as both the scale and number of such projects are set to increase.

  • Eye on Stion, Part I: Moduling in Mississippi makes sense for upstart CIGSSe PV company

    Chip Shots Blog | By Tom Cheyney - 05 January 2011, 05:09

    When Stion started looking for sites to establish its first volume production plant, Mississippi was not even on its radar. After vetting some “100 different opportunities, state and local flavors and locations,” the San Jose-based thin-film PV module company had “narrowed the list down to a half-dozen or so pretty quickly,” including Texas, Virginia, Michigan, and California, according to CEO Chet Farris. But then Pierre Lamond of Khosla Ventures (a VC investor in Stion) provided an introduction for Farris with the current governor of the Magnolia state and former chairman of the Republican Party, Haley Barbour.  Less than five months after an initial meeting between the two chief execs, Stion has agreed to—and the Mississippi state legislature approved—an incentive-laden deal for the CIGSSe firm to build its factory in Hattiesburg.

  • Waiting on the Feds: Several PV projects, factory expansions hinge on DOE loan guarantee decisions

    Chip Shots Blog | By Tom Cheyney - 30 December 2010, 20:19

    What do the California Solar Valley Ranch (250MW AC) and Agua Caliente (290MW AC) projects have in common? The obvious link is NRG Solar, which recently agreed to make hundreds of millions of dollars in equity investments and eventually buy the pair outright from SunPower and First Solar, respectively. But arguably the most important commonality the two projects share is this: both deals hinge on whether or not they get financing assistance from the Federal government in the form of a DOE loan guarantee.

  • Extension of U.S. Treasury’s cash grant program bodes well for solar industry at close of 2010

    Guest Blog | By Alan King - 21 December 2010, 17:38 | 1

    Alan King of Canadian Solar notes that while the extension of the U.S. Treasury’s 1603 cash grant program has positive implications for the solar industry in 2011 and beyond, there’s much work still to be done to increase PV’s percentage of the country’s overall energy portfolio.

  • Photovoltaics International 25th Edition

    In this issue we offer some insights into what the next wave of photovoltaic technologies may look like as that upturn gathers pace. Industry observers have been in broad agreement that the major next-gen PV technology innovations won’t happen straight away. But there’s also little doubt that the search is now on in earnest for the breakthroughs that will come to define the state of the art in the industry in the years to come.

  • Manufacturing The Solar Future: The 2014 Production Annual

    Although the past few years have proved extremely testing for PV equipment manufacturers, falling module prices have driven solar end-market demand to previously unseen levels. That demand is now starting to be felt by manufacturers, to the extent that leading companies are starting to talk about serious capacity expansions later this year and into 2015. This means that the next 12 months will be a critical period if companies throughout the supply chain are to take full advantage of the PV industry’s next growth phase.
