Project construction safety in utility-scale solar

By Matthew Skidmore, CEO of CS Energy

Construction trades are among the most dangerous, and solar is no exception. Matthew Skidmore of CS Energy explains why safety is paramount for solar project developers, project owners, financiers and EPCs.

Agrophotovoltaics: harvesting the sun for power and potatoes

By Boris Farnung; Stephan Schindele; Maximilian Trommsdorf

The question of whether to use valuable land for farming or solar power generation has been a subject of fierce debate in the green energy transition. But, as Boris Farnung, Maximilian Trommsdorff and Stephan Schindele of Fraunhofer ISE write, the two activities need not be in conflict with each other and, with a new generation of solar technologies, can in fact be mutually beneficial.

Weathering the storm

By Joseph Goodman; Frank Oudheusden

Hurricane-strength winds are a clear threat to solar installations in island nations, where PV is becoming an increasingly popular solution to climate change-related issues. Joseph Goodman and Frank Oudheusden, co-authors of a recent study on designing hurricane-ready solar systems, offer an insider’s view of how the challenge is being met.

Floating PV systems – an overview of design considerations

By Gijo George; Pranav Patel

Floating solar has huge potential in areas where difficult terrain or land constraints make ground-mounted systems impractical. Gijo George and Pranav Patel of DNV GL explore some of the technical challenges in designing and building floating PV projects.

A case for accuracy: Pyranometer or satellite irradiance data?

By Mauricio Richter; Clive Lee

Accurate irradiance data is key for assessing the feasibility, profitability, and performance of solar energy assets. 3E and Kipp & Zonen investigate the benefits of combining pyranometer and satellite-based irradiance data for optimal planning and operation of PV plants

Game changers: the rise and rise of 1,500V technology

By Patrick Fetzer

Two years ago, 1,500 volt PV systems were predicted to become the industry standard in the utility-scale segment. Patrick Fetzer of 1,500V pioneer GE looks at how far the technology has come and what further innovations could lie around the corner

Crunching the numbers on floating solar

By Sara Verbruggen

A major new study published by the World Bank has underlined the scale of the opportunity represented by floating solar systems, but highlighted issues of cost, bankability and regulation still facing this emerging branch of the solar industry. Sara Verbruggen reports on the first serious piece of heavyweight analysis of the prospects for floating solar

Offshore floating solar – a technical perspective

By Børge Bjørneklett

With floating solar on lakes and reservoirs well on the way to becoming a mainstream concept, attention is now turning to the possibilities offered by offshore systems. Børge Bjørneklett describes some of the pioneering R&D work being undertaken in the race to take solar to the open seas

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.

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

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.

A different direction

By Liam Stoker

As Europe and other hot PV markets transition to low- or no-subsidy environments, could a different direction help improve solar economics? Liam Stoker looks at why east-west orientated projects are increasing in popularity

Reducing uncertainty in PV yield assessments

By Mauricio Richter

When estimating the expected yield of a PV plant for financial risk assessment purposes, understanding the uncertainties of any model is crucial. Mauricio Richter of 3E investigates some of the emerging practices for obtaining and interpreting data to ensure the most accurate results
