    Latest effective PV capacity trends delay greenfield fab development

    Guest Blog | By Finlay Colville - 13 October 2014, 08:55

    How far can existing PV capacity go, in terms of keeping up with end-market growth? This is one of the key issues in terms of capital expenditures and tool suppliers waiting for an uptick in bookings. It is also essential to understand in terms of forecasting end-market demand in 2015, at a time when trade uncertainty and the preference for project financing is keeping new ‘greenfield’ fab build at a minimum.

  • Mission Solar Energy: New PV star rising over Texas

    Guest Blog | By Sam Martens - 08 October 2014, 16:27 | 2

    In late 2011, Mission Solar Energy made the first of several bold decisions:  build a silicon-based PV manufacturing plant in the US, a market long dominated by thin-film technologies. An even more unusual decision followed to locate the company in San Antonio, Texas, rather than California or Arizona where US solar markets are well established. Then, Mission Solar made the gutsy move to push forward with the development of an n-type monocrystaline silicon based product when the market was being dominated by p-type multicrystaline silicon modules coming out of Asia.

    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.
