  • SPI 2010 interview: A tuneful conversation with Canadian Solar’s Shawn Qu

    By Tom Cheyney - 22 October 2010, 17:18

    Canadian Solar’s Shawn Qu has come a long way since he matriculated to the University of Manitoba from China in 1989 as a grad student named Xiaohua. He fondly recalls that “cold, cold Winnipeg winter,” walking alone on the icy streets, listening to that “New World music” on his Walkman. These days, he says he doesn’t have much time for music (although he’s putting a good sound system into his new house), since his obligations as chairman/president/CEO of the solar company named after his sometimes-chilly adopted country consume most of his waking hours. I caught up with Qu at Solar Power International; although he was fighting a scratchy throat during our chat, he enjoyed a nice, harmonized view of a booth wall’s worth of photos of Canadian Solar modules deployed in various projects.

  • SPI 2010 recap: PVT Solar’s hybrid photovoltaics-thermal system is more than a bunch of hot air

    By Tom Cheyney - 20 October 2010, 17:18

    While photovoltaics’ crucial role in the renewables revolution is indisputable, that wonderful conversion of photons into useable electricity provides only part of the solution set. What about utilizing much more of that solar energy (as in 80-90%) that isn’t converted by the panels into homegrown juice? Taking a step outside my usual pure-play PV box at the recent Solar Power International show, I met with several innovative companies, including PVT Solar, which hopes to become an all-star player in the hybrid solar technology arena.

  • SPI 2010: Witnessing the ongoing coming-out party of CIGS thin-film PV

    By Tom Cheyney - 15 October 2010, 17:23

    The ongoing saga of copper-indium-gallium-(di)selenide photovoltaics provided one of the talking-point touchstones of this year’s Solar Power International show. Will solar historians look back to 2010 as the beginning of the Production Age of CIGS? That may be presumptuous and premature, since the thin-film PV’s slice of the overall solar shipment/deployment pie remains small.

  • First Solar reacts to China and Taiwan dominance in 2010

    By Finlay Colville - 15 October 2010, 11:13

    Between 2006 and 2009, First Solar set clear benchmarks for all solar cell and thin-film panel manufacturers by expanding at unprecedented rates while, at the same time, commanding industry-leading capex, opex and yield metrics. Over this period, their rapid ascent to leading worldwide producer in 2009 with a (production) market share of 12% was an inevitable consequence of enacting meticulously on this game plan. Indeed, midway through 2009, projected global market demand for 2010 suggested that continuous improvement by First Solar in operating costs, production line throughput, and efficiency would be more than sufficient to retain—or even expand upon—current market share.

  • SPI 2010: Convention center’s photovoltaic arrays help power North America’s main solar event

    By Tom Cheyney - 11 October 2010, 17:33

    Thousands of solar panels help energize the Los Angeles Convention Center, one of the first exhibition hall complexes to put photovoltaic power to work in a meaningful way. Two arrays totaling a combined 392kW were installed by the Los Angeles Department of Water and Power in 2000–2002: 144kW on the canopy of the center’s south hall and 248kW integrated as car shades on top of the Cherry Street parking garage.

  • Top-tier PV fabs approach 90% capacity conversion

    By Finlay Colville - 05 October 2010, 11:26

    Have you been confused by the current “sold-out” situation for PV manufacturers and then see reports stating that factory utilization levels averaged 50% or 60%? Finlay Colville, senior analyst at Solarbuzz, explains in this guest blog that a more accurate way of reporting utilization rates among PV module manufacturers is required, one that better matches real-world utilization rates.

  • Sarnia hits 80(MW): First Solar, Enbridge open world’s largest (for now) photovoltaic power plant

    By Tom Cheyney - 04 October 2010, 17:33 | 1

    Eighty megawatts of cadmium-telluride PV modules represents a lot of glass. As in more than 1.3 million panels’ worth, weighing over 15.6 million kg. And that’s not counting the thousands of tons of steel in the form of posts, tilt brackets, and the like, let alone the hundreds of kilometers of cabling. As impressive as they are, it’s not the massive amount of glass and steel that matters, but the sheer installed AC capacity of the 1150-acre First Solar-built/Enbridge-owned site outside of Sarnia, in the southwestern corner of Ontario a little over four miles from the shore of Lake Huron. Going by the name Sarnia 80, the megasystem is, for the time being, the largest operational photovoltaic power-generating station on the planet, thin film or crystalline silicon, by a couple tens of megawatts. “I call it ‘the brief moment of glory,’” mused First Solar’s Peter Carrie.

  • Exclusive: PV in the USA, Part III—Nextronex joins solar power system optimization conversation

    By Tom Cheyney - 01 October 2010, 17:48

    Start-up companies face many perils on the path to viability and profitability, but tornadoes are not usually included on the risk/challenge list. In Nextronex Energy Systems’ case, a deadly twister in early June roared within a few hundred meters of the company’s facility outside of Toledo, tearing the side off the local police station, destroying a nearby home, and tossing cars around like Matchbox toys. The PV inverter/system optimization firm escaped unscathed, although the neighbor in the other half of the building sustained minor roof damage. When I asked new boss Bruce Larsen about the storm, he quipped, “I’m glad I became CEO after the tornado, not before!”

  • Memo to REC Solar: Your advertisements may be sending the wrong message

    By Tom Cheyney - 27 September 2010, 17:57

    A quarter-page ad in the front section of Saturday’s Los Angeles Times almost made me choke as I sipped my morning coffee. “SOLAR WON’T LAST” the tagline cried out in large, all-capped type. Puzzled, I peered closer, squinted actually, at the much-smaller fonted copy and caught the elliptical continuation of the tagline, “…much longer at these prices.” Reading further, I realized that, the ad was promoting solar, not dismissing it. The copy goes on to tout California-based installer REC Solar’s expertise in helping the consumer take advantage of “limited-time government rebates” and the company’s claim to have installed “more solar electric systems than any other company.” The reader is then directed to the curiously named http://www.exposesolar.com website.

  • Golden state of mind: Air Resources Board approves 33% RES, capping wild Cali solar (news) cycle

    By Tom Cheyney - 24 September 2010, 10:02

    (CORRECTED/UPDATED) Over the past two days, California has become the center of the solar power universe—at least its news cycle. A cascade of announcements has tumbled into the mediasphere in the form of nine-figure acquisitions, approval and build-starts of hundreds of megawatts of CSP and PV projects, the largest tubular thin-film installation to date, the Republican gubernatorial candidate’s decision on Prop. 23 (AKA The Dirty Energy Proposition), and last but not least, the vote by the California Air Resources Board to require the state’s utilities to get 33% of their energy from renewable sources by 2020.

  • Photovoltaics International 24th Edition

    Signs earlier in the year of the global industry entering a growth phase have now been confirmed beyond any doubt. Almost all the big-name suppliers have now announced some form of manufacturing capacity expansion, a trend that analysts agree will only gather pace as long as the levels of demand predicted over the next few years turn out to be correct.

  • 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.
