Forecasting | Short-term PV forecasting offers a multitude of benefits, from trading on wholesale power markets to improved plant operation. Sara Verbruggen reports on some of new the technologies driving forward improvements in the accuracy of forecasting techniques.

Long time coming

By Andy Colthorpe

First developed by NASA, flow batteries are a potential answer to storing solar – and wind – for eight to 10 hours, far beyond what is commonly achieved today with lithium-ion. In the first of a two-part special report, Andy Colthorpe learns what the flow battery industry faces in the fight for commercialisation.

Emerging market briefing

By Tom Kenning; Ben Willis

Tom Kenning and Ben Willis look at the latest developments in some of the most promising emerging PV markets worldwide. This issue features Pakistan, Tunisia and Uzbekistan.

Black to gold: The oil & gas majors plotting a solar revolution

By Liam Stoker

The global decarbonisation agenda and still-tumbling costs are sending oil and gas giants and traditional energy majors into the PV market, and in a big way. Liam Stoker investigates what that means for the international solar market.

Advancing BIPV in Europe

By Dr. Maider Machado; Jose M. Vega de Seoane; Dr. Francoise Burgun; Dr. Ya Brigitte Assoa; Simon Challet

The EU-funded PVSITES project is working on a number of initiatives aimed at accelerating the roll-out of building-integrated PV across the continent. Members involved in the initiative outline some of the efforts being made to unleash BIPV’s as-yet untapped potential.

Project briefing - Hero Launches India’s First Solar-Wind Hybrid Project

By Tom Kenning, Solar Media

Delhi-headquartered renewable energy firm Hero Future Energies has completed India’s first largescale solar and wind energy hybrid project in the state of Karnataka. The project at Kavithal, Raichur District, which included an existing 50MW wind farm, now has a neighbouring 28.8MW solar PV site to form a hybrid system.

Investigating the impacts of floating solar on the water environment

By Dr Ian Jones; Dr Alona Armstrong

Despite the growing popularity of floating solar installations, relatively little is known about their environmental impacts on water bodies. Ian Jones and Alona Armstrong are leading a research progamme to understand more about how the environmental benefits of floating PV can be harnessed and the downsides minimised

The rise of green solar bonds?

By Vicky Münzer-Jones; Stacey Giunta

Banks will be unable to fully finance solar on the scale envisaged in the transition to a low-carbon economy. Vicky Münzer-Jones and Stacey Giunta look at the role of solar bonds in bringing much needed capital to the sector.

Detailed yield analysis and optimisation of BIPV systems by simulation

By Johannes Eisenlohr

BIPV systems do not follow many of the rules associated with conventional or ground-mounted PV arrays. Johannes Eisenlohr of Fraunhofer ISE examines some of the technical solutions being developed to simulate BIPV design and thus make it more affordable.

On-site PID testing

By Dr Volker Naumann; Dr Nadine Schüler; Dr Christian Hagendorf

Potential-induced degradation (PID) is still one of the main reasons for unpredictable power losses in PV power plants. Volker Naumann, Nadine Schüler and Christian Hagendorf of Fraunhofer CSP and Freiberg Instruments present an approach for quick on-site PID testing of mounted PV modules, allowing PID diagnosis and prognosis of PID-related yield losses

Taking smart to the edges of the world

By David Pratt, Solar Media

Islands around the world provide ideal conditions for trialling new approaches to energy provision. David Pratt reports on some of the work going on globally to bring the benefits of cutting-edge renewable energy, storage and smart grid technologies to the world’s geographically isolated communities.

Perspectives on risk mitigation measures for PV power plants: insurance and quality assurance

By Thomas C. Sauer; Georg Fischer, EXXERGY

In the previous issue of PV Tech Power, quality assurance was considered as a key measure in maximising PV power plant performance and ensuring safety. Building on this train of thought, Thomas Sauer and Georg Fischer from EXXERGY examine insurance as a risk mitigation measure, based on analysis of more than 3,600 insurance claim cases.
