Solar manufacturer Jolywood, which supplied almost 500 MW of its bifacial tunnel oxide passivated contact panels for Oman’s Ibri II facility, has claimed the power plant is the biggest to date to deploy the high-efficiency technology.
The inverter and battery manufacturer said it has been sitting on a record order backlog for the current three month window and the opening quarter of the new year, which may in part be down to a long Covid shutdown at its Vietnamese production base.
Israel-based Augwind has built its first 250 kW/1 MWh compressed air storage system for the collective community of Yahel, in the southern, desert part of the country. The commercial scale facility will be connected to a PV system and will be used for behind-the-meter services.
Fotowatio Renewable Ventures’ (FRV) Australian platform includes 637 MW (DC) in projects already operational or under construction, and a pipeline comprising 7 GW of solar projects and 1.3 GWh of battery storage.
Scientists have demonstrated a zinc-ion battery that overcomes many of the challenges for this technology. By working with a highly-concentrated salt solution as the electrolyte, the group was able to achieve stability over more than 2,000 cycles combined with a strong electric performance. The group says that its work opens up “a viable route to developing aqueous batteries for emerging electrochemical energy storage applications.”
The new headquarters planned by DEWA is intended to consume no more annual electricity than it generates, from a large volume of rooftop and building-integrated PV.
Polluting energy sources received more than $3 trillion from the EU and 19 of the world’s largest national economies over that four-year period, despite G20 members having pledged to phase-out fossil fuel subsidy and address climate change back in 2009.
The Gaza Strip, one of the most densely populated areas in the world, is embracing solar energy as a reliable local energy source. However, its 2 million residents still only have access to electricity for just a few hours per day. Amjad Khashmann reports on damages to installed PV systems and the urgent need for new installations to support education, water, and health care.
Scientists demonstrated a perovskite-silicon tandem cell that reached 27% conversion efficiency. Though higher tandem cell efficiencies have been achieved, this represents a big jump in efficiency for those utilising n-i-p architecture, which previously had not surpassed 22%.
Saudi scientists have tested several cooling technologies for solar panels and have found that active techniques work better than passive ones under harsh climatic conditions. The most effective one consists of a system based on four heat pipes immersed in a box of liquid, as liquid bulk, integrated with the back of the solar panel.
