This year has witnessed upheaval in the global energy system as inflation, geopolitical conflict, and the reality of a changing climate continue to drive the transition to cleaner energy. Next year, these trends are likely to continue and accelerate as renewable energy adoption continues to grow and the inextricable link between energy security and national security is increasingly recognized. Alan Greenshields, of US-based iron-salt flow battery maker ESS Inc, offers four predictions for 2023.

New life-cycle assessment (LCA) data for PV systems confirms that greenhouse gas emissions from 1 kWh of solar electricity are far lower than emissions from fossil-fuel power plants. The difference has been fairly constant since 2018, but has improved substantially since when IEA PVPS started reporting on this measure in 1996.

PV module prices have finally stabilized and a slight downward trend has even started to set in. Whether this will continue depends mainly on how demand shapes up over the next few months. The softening of prices reflects a gradual build-up of inventories which need to be drawn down again this year, if possible – even if it means slashing prices. But for other PV-system components, the situation is quite different, writes Martin Schachinger of solar wholesaler pvXchange.

While the climate summit held at Sharm El Sheikh last month prompted pledges of raised funding for solar lanterns and single-panel systems, the money allocated to date is woefully short of what has been estimated would be required to provide universal access to electricity this decade.

It will also end the home battery premium earlier than initially announced, from April 2023. The premium for heat pump boilers, on the other hand, will be retroactively doubled.

Germany’s latest solar auction allocated 104 MW of solar for buildings and noise barriers on motorways. The tender volume was 202 MW which went partly unsubscribed. The volume-weighted average award value fell slightly to €0.0874 ($0.093)/kWh.
