Cryogenic, long-duration energy storage in a 100% clean energy future

By Dr. Javier Cavada

A key missing piece in the clean energy puzzle is the question of how to provide baseload power in an electricity system dominated by intermittent renewables. Javier Cavada of Highview Power examines cryogenic long-duration storage as a possible solution.

Peak time to take action

By Andy Colthorpe

In the hierarchy of grid needs, peaking power is often a priority in terms of providing resiliency and balance to the network. This is usually provided by natural gas turbines, which come at a high environmental and economic cost. Andy Colthorpe charts the rise of the solar-plusstorage peaker plant.

Fixed-tilt versus single-axis tracker arrays in India

By Geoffrey S. Kinsey ; Madhusudan Partani; Mukund Kulkarni; Brijit Shetty; Dr. Rubin Sidhu; Dr. Jie Zhang

India has become the world’s second largest market for trackers as it chases its ambition of installing 100GW of solar by 2022. Geoffrey S. Kinsey, Madhusudan Partani, Mukund Kulkarni, Brijit Shetty, Rubin Sidhu and Jie Zhang report on efforts to better understand the performance benefits of trackers over fixed-tilt mountings

Is LeTID degradation in PERC cells another degradation crisis even worse than PID?

By Dr. Radovan Kopecek; Dr. Joris Libal; Lejo J. Koduvelikulathu

Light- and elevated temperature-induced degradation – LeTID – is emerging as a potentially serious problem affecting PV modules employing PERC technology. So why isn’t the industry more aware of it, ask Radovan Kopecek, Joris Libal and Lejo J. Koduvelikulathu of ISC Konstanz.

Optimising Europe’s solar plants: O&M guidelines to further solar growth

By Guillermo Oviedo Hernández; Elena Bernardi; Jörn Carstensen

Solar O&M is rapidly evolving as PV deployment gathers pace worldwide. Guillermo Oviedo Hernández, Elena Bernardi and Jörn Carstensen of SolarPower Europe’s O&M Task Force look at some of the emerging trends, practices and business models in this increasingly critical arm of the solar industry.

Project briefing

By Tom Kenning

While Filipino policymakers pondered a controversial bill that would allow a solar company to set up a micro-grid and transmission franchise aiming to improve power supply across the country, a small town on the island of Mindoro was already enjoying round-the-clock electricity for the first time ever. The town of Paluan, situated in the northwest corner of Mindoro, the seventh largest island in the Philippines, dominated by an agricultural society and dubbed ‘the brownout capital of the Philippines’, is receiving power from Southeast Asia’s largest micro-grid, combining solar PV, energy storage and diesel technology.

Power plant wire management

By Samuel Truthseeker

Effective management of cabling in a PV system can greatly impact its lifetime maintenance requirements and thus profitability. Samuel Truthseeker of TECSI Solar looks in detail at the latest developments in wire management and highlights several reliability considerations.

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.

Ensuring the bankability of the UK’s low-carbon fleet

By Gareth Miller, Cornwall Insight

Strong policy support to safeguard the bankability of low-carbon energy technologies and underpin the UK’s ongoing decarbonisation efforts. Gareth Miller of Cornwall Insight outlines proposals for a new route to market that would guarantee future investment in much-needed renewables such as solar and onshore wind.

Subsidy-free solar: Europe’s search for new allies

By José Rojo, Solar Media

Led by a bullish Spain, the industry’s free-market revival has dispelled memories of the FiT fallout but also ushered in an era of uncertainty. José Rojo charts players’ efforts to master the rules of a new game of tough PPA interactions and merchant risks.

Emerging market briefing

By Tom Kenning

Tom Kenning looks at the latest developments in some of the most promising emerging PV markets worldwide. This issue features Saudi Arabia, Colombia, Mexico and the UAE.

Turkey takes the winding road to solar success

By Ekin İnal; Chris Down

Turkey has around 5GW of installed solar capacity, but potential for much more. Ekin İnal and Chris Down explore the latest developments in Turkey’s solar market and the regulatory reforms that could help PV take a much larger share of the country’s energy mix.

Plugging the hole: How can solar fill UK nuclear’s void?

By Liam Stoker

When Hitachi suspended development of its planned new nuclear power plant at Wylfa in early 2019, many thought the news would blow a hole in the country’s decarbonisation plans. But as costs continue to fall, even the UK government, not usually considered to be renewables’ closest ally, has pointed to the technologies’ role in plugging that gap. Liam Stoker looks at what might be required.

Land of the rising shadows

By Tom Kenning

At the end of 2018 the Japanese government caught solar developers by surprise with a raft of punitive regulatory changes. Tom Kenning reports on the short- and long-term impacts these could have on the country’s PV industry.

Halting desertification in the Sahel with solar power

By Tom Kenning

Solar power is at the heart of an ambitious plan to tackle environmental degradation and poverty in the Sahel region. Tom Kenning reports on a programme that, if successful, could bring a multitude of environmental and economic benefits to a fragile part of the world.
