    Maximising power production of large PV systems: PID detection and mitigation

    Guest Blog | By Rubina Singh - 13 April 2015, 08:34 | 2

    With potential induced degradation emerging as a major issue for PV power plant performance, manufacturers have responded by developing technologies to mitigate the problem. But a lack of long-term field data on PID means the jury is still out on whether these efforts will be sufficient, writes Rubina Singh of Fraunhofer CSE.

    Jeremy Leggett: The oil, coal and gas industries are in deep trouble

    Interviews | By Peter Bennett - 09 April 2015, 10:56

    Author, campaigner and solar energy entrepreneur Jeremy Leggett’s latest book, ‘The Winning of the Carbon War’, has just been published as a 10-part serial in the run up to the Paris climate summit in December. In a special interview, he speaks to Peter Bennett, editor of PV Tech’s sister site, Solar Power Portal, about the global solar industry’s role in the clean energy revolution he believes is inevitable as the oil, gas and coal industries become increasingly unstable.

    The outlook for the solar industry in 2015 – key questions

    Guest Blog | By Susanne von Aichberger,Ash Sharma - 01 April 2015, 11:21 | 1

    Earlier this week market research firm IHS issued revised figures for global PV installs in 2014 and confirmed its 2015 guidance at 57GW. Ahead of a webinar to be jointly hosted with PV Tech on Wednesday 15 April, IHS’ senior analyst, Susanne von Aichberger, and senior director, Ash Sharma, answer some questions on the key PV trends for 2015.

    China 17.8GW, a record solar PV installation target for 2015. Achievable?

    Guest Blog | By Frank Haugwitz - 24 March 2015, 09:55

    Last week Chinese authorities announced a 17.8GW PV target for 2015, an even more ambitious quota than the one set in 2014, which was missed.  Beijing-based Chinese solar market expert, Frank Haugwitz, asks whether China can live up to its aspirations this time around.

    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.
