    Adani dumps SunEdison in favour of richer contenders

    Editors' Blog | By Mark Osborne - 19 August 2015, 18:47 | 1

    Despite Reuters and whole bunch of mainstream media as well as some specialists in the renewable’s field having initially pronounced a major US$4 billion JV between SunEdison and India’s large conglomerate, Adani Group was a done deal back at the beginning of the year, those that did so should re-acquaint themselves with the terms ‘memorandum of understanding’ (MOU) and ‘feasibility study’.

  • Module testing

    Your module passed qualification testing, but is it also durable?

    Guest Blog | By Rubina Singh,Dr Cordula Schmid - 19 August 2015, 06:00

    The Fraunhofer PV Module Durability Initiative is seeking overcome the fact that current certification regimes give no indication of a module’s lifetime performance. The team behind the initiative describe its latest findings.

  • Cracking the feedstock puzzle for larger solar ingots

    Guest Blog | By Til Bartel - 14 August 2015, 10:48

    How silicon feedstock is packed into casting crucibles can have a big impact on the size and cost-efficiency of the resultant solar ingots. Til Bartel looks at some of the latest thinking around this essential stage in the PV manufacturing supply chain.

    Is China ready for 20GW in 2015?

    Guest Blog | By Frank Haugwitz - 27 July 2015, 17:14

    So far in 2015, Chinese domestic PV deployment has outstripped last year’s rates. A 20GW year would set a benchmark for China’s new five-year plan for solar development due to come into effect next year, writes Frank Haugwitz.


  • Photovoltaics International 27th Edition

    Now that the PV industry has unquestionably entered a new growth phase, all eyes are on which technologies will win through into the mainstream of PV manufacturing. PERC, n-type, p-type bifacial, heterojunction – all have become familiar terms in the ever-growing constellation of solar cell technologies. The question is which will offer manufacturers what they are looking for in improving efficiencies and cutting costs.

  • 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.
