As it matures, the solar industry is moving beyond the use of Performance Ratios (PR) as the go-to performance metric for operational sites. Christopher West, head of central engineering - solar PV delivery unit at Statkraft, argues the case for PRs to be replaced by alternative, more evolved methods of assessment.

With extreme weather events becoming increasingly common, Molly Lempriere takes a look at how to ensure a solar installation is prepared to manage wind, hail, heat and anything else nature has in store.

Having been hailed as the new king of electricity markets, Liam Stoker charts solar’s journey up until this point, explores how it has earned the crown and poses the question: what next for PV?

With green hydrogen from renewables at the core of a number of decarbonisation strategies globally, the first large-scale projects face a number of challenges integrating into the energy system. Molly Lempriere explores the barriers to developing large-scale green hydrogen, the technologies easing interaction and the benefits of hydrogen for grid balancing and storage.

Vietnam experienced enormous growth in solar deployments in 2020, with as much as 9GW being installed as the successful FIT policy drew to a close. Edgar Gunther explores how that policy came to be so successful, and what the future holds for solar PV in Vietnam.

Scatec Solar beat South Africa’s nationwide COVID-19 enforced lockdown by just a day when it completed the 258MW Upington solar complex in April 2020. Here’s how they did it.

It has always been anticipated that by the early 2020s, the feed-in tariff would have tapered away in Japan’s booming solar market. Andy Colthorpe speaks with analyst Izumi Kaizuka at RTS Corporation to learn more about what the future holds for post-subsidy solar in Japan.

In arid regions soiling can greatly impact the energy yield of PV systems and drive up their O&M costs. Benjamin Figgis, Amir Abdallah, Maulid Kivambe, Brahim Aissa, Kamran Ali, Cédric Broussillou and Veronica Bermudez of the Qatar Environment & Energy Research Institute and Klemens Ilse of the Fraunhofer Center for Silicon Photovoltaics review the main challenges associated with soiling of PV plants globally, and the most promising techniques for dust prevention and cleaning in dry climates, drawing on research results from six years of PV performance and soiling studies at the QEERI’s Outdoor Test Facility in Doha

SPONSORED: During SNEC 2019 in Shanghai, PV Tech and Chinese conductive paste leader DK Electronic Materials (DKEM) discussed trends in metallization and interconnection and the need for close collaboration among the value-chain to drive innovation for efficient PV products.
