  • UK fails to reach renewable energy targets

    Guest Blog | By Emma Hughes - 21 April 2011, 15:54 | 1

    As we all try and pick ourselves back up from recent knockbacks in the UK’s renewable energy sector, it’s rather worrying to find out that we actually missed our renewable energy target for 2010 by 3.5%. As a result, the levels of confidence we have in reaching the much larger, more daunting target set for 2020 are plummeting by the second.

  • Gigawatt CIGS, Part I: Solar Frontier boldly goes where no chalcopyrite TFPV company has gone before

    MIYAZAKI, JAPAN—As you drive through Kunitomi’s lush agricultural plain, a large white building comes into view on a distant hill. Its bright rectangular shape blocks out part of the spectacular backdrop of green-hued mountains, and as you edge closer, a distinctive red, blue, and white logo becomes visible, bearing the name “Solar Frontier.” After touring most of the company’s massive brand-new 900MW copper-indium-selenide factory, the sense of exploration and discovery that the corporate branding connotes has taken on a whole new meaning. This is not your everyday thin-film production facility, but the largest of its kind, representing an all-in billion-dollar investment bet by parent company Showa Shell Sekiyu.

  • CPV-7 commentary, Part II: Welcome to the era of the 40%-plus efficiency multijunction solar cell

    Chip Shots Blog | By Tom Cheyney - 15 April 2011, 01:51

    The company touting the top NREL-validated III-V multijunction solar cell conversion efficiency results—Solar Junction—kept a low profile at the recent CPV-7 conference, while just about every other cell developer and manufacturer made oral and poster presentations at the event. The newcomer’s news that its “production-ready” 5.5 X 5.5mm spectrally adjustable cell hit a record-breaking 43.5% at >400 suns comes on the heels of most of the other CPV cell players announcing that they are—or soon will be—at 40% efficiencies in manufacturing. Although Solar Junction deserves kudos for cracking 43% and then some, there’s a difference between what the start-up calls “production-ready” cells and other companies’ cells that are actually in production and scaling.

  • Oh to be on, Copper Mountain: A behind-the-fence peak at the big PV site and its CSP neighbor

    Chip Shots Blog | By Tom Cheyney - 12 April 2011, 00:00 | 1

    A few dozen miles outside of the reality-bending gaud-opulence of Las Vegas dwell two separate portions of one of the largest non-colocated concentrations of renewable energy generating facilities on the planet. To the east of Sin City, that massive testament to public works projects, Hoover Dam, has been cranking out terawatts of old-school clean hydropowered electricity for decades as well as supplying water to the burgeoning populace of the US southwest from its location on the depleted Colorado River astride the Nevada-Arizona border. Far from the Strip’s bright lights out in the expanse of the Eldorado Valley some 30 miles southwest of the dam, a pair of sizeable solar farms—the Nevada Solar One CSP plant and the recently energized Copper Mountain Solar 1 project—pull in sun juice within spitting distance of each other.

  • CPV-7 commentary, Part I: Amonix thinks big, while Energy Innovations bets small(er) is beautiful

    There are still a lot of “ifs” when it comes to concentrator photovoltaics, but it’s starting to look like the question of “when” the technology will start to gain serious market traction may be sooner than some think—at least if one is to believe the 400-plus CPV faithful attending the CPV-7 conference in Las Vegas. The onslaught of technical presentations coupled with ample time for networking and schmoozing make the event one of the sector’s group hugs (or shrugs) of the year. Two major systems companies, Amonix and Energy Innovations, are among those leading the way.

  • Pistachio photovoltaics: SolFocus narrows CPV’s commercial chasm with new project, growing pipeline

    Chip Shots Blog | By Tom Cheyney - 01 April 2011, 18:01

    Although the sun’s power can be harvested on most days in the Central Valley of California, pistachios must be picked when they’re ready. In the case of Nichols Farms, the timing of the fall harvest meant that the construction of the 1MW SolFocus concentrator PV power plant had to be delayed until those bushels of green-fleshed nuts were reaped. Plus, the half-dozen acres selected for the installation (chosen because of their proximity to the grid-interconnect point and easy road access) included plantings of young trees, which had to be relocated to another part of the farm before the site was prepped. As a result, the first shovel of the project, which was originally scheduled to break ground in late September, was pushed back to the second week of November, according to SolFocus’ Nancy Hartsoch.

  • Misleading title: New PV technology roadmap is anything but international

    Chip Shots Blog | By Tom Cheyney - 31 March 2011, 02:06

    The idea of an industry roadmap for photovoltaic technology and manufacturing, along the lines of the International Technology Roadmap for Semiconductors (ITRS), came to fruition a few years ago in the form of, you guessed it, the International Technology Roadmap for Photovoltaics (ITRPV). The second edition of the solar effort has just been published by the Crystalline Silicon PV Technology and Manufacturing Group (CTM) in conjunction with SEMI’s PV Group, and a summary of its contents presented at the recent PV Fab Managers Forum in Berlin. Just one problem though: with nary a single non-European cell or module manufacturer participating, the very name of the effort is misleading, since it is anything but international.

  • UK FiT review: we will not be moved

    Guest Blog | By Emma Hughes - 30 March 2011, 16:57

    Since the fast track review bombshell was dropped last week I have been thinking about what kind of implications this will have on the UK solar industry as a whole—not just how it will affect the large-scale market. As we all know, one of the many things this country’s renewable energy industry lacks is experience, which is why it was so encouraging to see some of the world’s largest and most influential solar players step onto British soil.

  • Apollo Solar recognizes US$390 million revenues for turnkey a-Si equipment in 2010

    Guest Blog | By Finlay Colville - 28 March 2011, 09:39

    During 2010, media coverage of a-Si tool suppliers often outweighed that of their own customers who were hard at work seeking new business for sub-10% efficient PV panels. With much of the attention on well-known names such as Applied Materials, Oerlikon, and Ulvac, other equipment suppliers located within the Asia Pacific region moved quietly – but efficiently - into the turnkey a-Si space, clocking up a host of new orders from enthusiastic thin-film entrants. And the two equipment companies receiving most of these new orders were Jusung Engineering and Apollo Solar Energy Technology.

  • Industry buffet, Part I: Greentech summit offers nutritious sampling of solar sector

    Chip Shots Blog | By Tom Cheyney - 24 March 2011, 19:04

    With its annual solar summit event, Greentech Media intermingles the various food groups of the PV and CSP communities for a tasty buffet. The market, technology, manufacturing, project development, and financial comestibles might come in the form of small plates of newsy nibblets or larger entrees that intrigue and challenge the intellectual palate. Like any fine culinary encounter, the conversations between mouthfuls are an important part of the experience. You walk away from the two-day info-sharing and networking feast satiated but not stuffed, unlike the often-painful mental indigestion that happens after a 15-course technical conference gorging or weeklong mega tradeshow binge.

  • Photovoltaics International 26th Edition

    Looking back, 2014 was a year of convalescence for a PV industry still battered and bruised from a period of ferocious competition. End-market demand continued apace, with analysts towards the end of 2014 predicting the year would see between around 45 and 50GW of deployment. That has begun to feed through to the supplier end of the market, with all the main manufacturers announcing capacity expansions in 2015 and further ahead.

  • 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.
