Anticipating silicon solar cells with significantly improved efficiency

Theoretical calculations indicate that under certain conditions silicon can endow solar cells with a much higher efficiency. Small silicon clusters may provide a source of accordingly modified silicon. However, to date these clusters have not been accessible in soluble form, a prerequisite for flexible processing. Researchers at the Technical University of Munich have now discovered […]

Deep disparities in the global energy system

Deep disparities define today’s energy world: The dissonance between well-supplied oil markets and growing geopolitical tensions and uncertainties; the gap between the ever-higher amounts of greenhouse gas emissions being produced and the insufficiency of stated policies to curb those emissions in line with international climate targets; the gap between the promise of energy for all […]

World’s largest solar-power water plant

The water desalination experts Rawafid Industrial and Advanced Water Technology (AWT) have built an ultra-modern plant for extracting drinking water on the coast of the Arabian Gulf in response to demand for a reliable supply of drinking water for a growing population. Sea water is processed here in a two-stage, solar-powered reverse osmosis process to […]

South Africa should open the door wider for renewables

South Africa’s advanced industrial and financial sectors, together with its abundant natural resources, have contributed in making it the second largest economy in Africa. But to bring power to the remotest corners of the country, to maintain its economic growth momentum and to reduce its carbon footprint, it must accelerate the adoption of efficient, economic, […]

US energy giant says renewables and batteries beat coal, gas and nuclear power

The energy industry is in the grip of massive change, with the cost of renewables and battery storage – without subsidies – beating gas, as well as existing coal and nuclear on costs. This is the view of Jim Robo, the CEO, president and chairman of NextEra, the biggest and most successful utility in the […]

Updated inverters and optimisers on the cards

SolarEdge is previewing a new version of its 120 kW three-phase inverter with synergy technology which is designed to enable quick and easy installation and inventory management. The company will also launch a new commercial power optimiser with two MPP trackers which connects to up to four modules. The new commercial inverter and power optimiser […]

Power developments in Africa, October 2019

PV project grows Egypt’s renewable energy portfolio A new 50 MW solar power plant is to be built in Egypt. The plant, which will be built in Zafarana, will be funded by the German Development Bank and is expected start delivering power before the end of 2020. The Zafarana plant is the second project executed […]
