Growing awareness of the advantages of using controlled quantities of impurities in solar silicon is closing the price gap between lower and higher purity feedstock, writes Til Bartel.
SolarCity has announced a partnership with Google-owned Nest to trial new customers in California using Nest’s smart thermostats in conjunction with solar power consumption. Omar Saadeh, senior grid analyst at GTM Research, spoke to PV Tech about the trend for solar companies partnering with smart home technologies and the increasing consumer appeal of energy management systems.
A lax management and maintenance regime can see the value of a PV system leach away over time. Laura Stern outlines some of the key steps in ensuring a system retains its value right up to the end of its planned lifetime.
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.
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.
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.
As we near the end of the first quarter of 2015, clarity over actual global PV market demand in 2014 remains elusive and confusing. Mark Osborne looks at the numbers.
Yingli Green’s PV module shipment guidance for 2015, compared to its four closest rivals could result in a further slide down the rankings this year.
Canadian Solar has become one of the world’s biggest integrated PV players. At last month’s PV Expo in Japan its CEO Shawn Qu told Andy Colthorpe about the company’s plans for Japan and beyond, and how it remains just a start-up at heart.
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.
