Despite the growth, one-off exceptional events in the fourth quarter hit the solar EPC’s overall fiscal performance. These included a prime subcontractor going bankrupt in Australia, rising module prices, and increased freight costs.

Underwater gravity energy storage has been proposed as an ideal solution for weekly energy storage, by an international group of scientists. The novel technology is considered an alternative to pumped-hydro storage for coasts and islands without mountains that are located close to deep waters, and may also be interesting for PV if used to store green hydrogen.

Conventional incentives such as renewable portfolio standards, feed-in tariffs or feed-in premium payments may lead to a price cannibalisation scenario for wind and solar, according to a new study from a German-Swedish research group. CO2 pricing is, however, considered an efficient tool to maintain their market value high enough to ensure new investments. A total system cost approach, rather than an LCOE perspective, is needed to understand the strong dependence of market value on policy choice though.

This year, PV cell manufacturers will face the challenge of transformation. Apart from adjusting the ratio of production for different-sized cells, some manufacturers are turning to next-generation opportunities, shifting investment from p-PERC to n-type technology. PV InfoLink Analyst Amy Fang discusses the issues facing n-type cell development this year.

Despite the impact of the pandemic and associated economic crisis, 2020 saw unprecedented growth in the solar market. With the International Energy Agency stating that high rates of capacity additions are the new normal, has the energy and investment environment fundamentally changed? Felicia Jackson in London explores these issues.

The Italian manufacturer has showcased a high-power multi-MPPT string inverter and modular conversion solution – designed to supply both decentralised and centralised systems.

Despite the global pandemic and recession, corporate purchases of clean energy are booming. Several factors are driving this trend, including falling costs, heightened appetite for sustainability among consumers and investors, and increased political will for net-zero development. In recognition of this, the UP Initiative will spend the third quarter investigating sustainable electricity supply. How are PPA models evolving? What are the critical issues around residual energy? And how can greenwashing be avoided? pv magazine investigates.

The speed of all transitions is inherently underestimated, and solar PV is no exception. The EU has grossly underestimated its coming of age, as its forecasts for 2020 were off by 67% for the Netherlands and 74% for Germany, writes Rolf Heynen, CEO of Dutch New Energy Research.

The four-day G7 summit in Cornwall ended with little cause for celebration from anyone worried about climate change. Most of the pledges that emerged were relatively old news, with the UK repeating its promise of £500 million for ocean conservation efforts and the group reaffirming its commitment to end support for coal production abroad.

Ruchi Gupta is a research fellow at the University of Geneva’s Institute for Environmental Sciences. She focuses on how flexibility options, such as sector coupling with hydrogen production, can support renewable energy integration and decarbonise a wide range of sectors.
