Weather and climate data: Answers to questions from the pv magazine webinar

Assessment of weather data and forecasting are vital in reducing risks and, therefore, financing costs and losses during the operation of solar plants. Following a recent pv magazine webinar, Finnish environmental firm Vaisala has prepared detailed answers to the main questions posed by participants.

Black silicon could exploit potential of multicrystalline technology

In recent times there has been a shift from multi to monocrystalline solar cells and modules. One reason for this is the difficulty of using diamond wire saws on multi wafers in production. Black silicon has the potential to change this and to increase the efficiency of multi, Bill Rever, Co-founder and Chief Marketing and Sales Officer at Advanced Silicon Group, said at EU PVSEC.

Flasher trends at EU PVSEC

Discussion about the adaptation of standards for Flashers, and the way in which high-performance and bifacial modules should be measured goes on. Berger Lichttechnik is now launching a new cell tester and Halm reports a three-digit number of delivered cell testers.

Interview: SunPower pivots to more conventional cell technologies and shingled cell modules

SunPower is famous for its back-contact cells, boasting one of the industry’s most advanced technologies. Josh Moore, SunPower Director, explains why the company is now ramping up 600 MW of production for different types of front-contact cells and shingled modules. He will pitch the advantages at pv magazine’s Future PV event to be held at SPI on Tuesday September 12.

Future PV: The feasibility of solar-powered hydrogen production

There is a solid business case to combine PV plants with electrolyzers, as generation costs are low enough to competitively produce hydrogen as a fuel, says Bjørn Simonsen of NEL Hydrogen. He will speak at pv magazine’s Future PV event at SPI in Las Vegas.

Interview: Using accurate weather data for asset management and risk reduction

Meteorological data are necessary to measure the performance of a solar plant, to ensure its yield and to effectively plan its maintenance. Gwen Bender, Vaisalas Product Manager for Solar Assessment Services discusses the importance of up to date, accurate weather monitoring, as opposed to relying on data from public sources.

Quality: Minor differences in yield percentage make the difference between good and bad investment

Changing technology, pressure to cut costs, dizzying price slumps and a number of other issues make solar module quality control as relevant as ever. The danger that modules could fail outright remains slim, so module reliability is still decisive for the success of the investment, explains George Touloupas, Director of Technology and Quality at CEA, in preparation of the 4th pv magazine Quality roundtable at SPI.

Poor quality planning: Shifting the blame, passing the buck

An installation company in the Midwest reports how blame was laid at their door for defective PV panels. The actual cause of the defects probably lie elsewhere.

Installation Innovation Award winner: Maxx-Solar Energy

After three weeks of intense voting, pv magazine and Hanwha Q CELLS is happy to declare Maxx-Solar Energy as the winner for its inventive project: delivering innovative financing solutions for solar PV in Africa.
