Public lighting: Lighting the way to smart city development

Public lighting is one of the services most visually seen by the general public within a city (though it almost goes unnoticed). Lighting provides a sense of visual safety and security. This improved sense of safety and security will often lead to an increase and further promotion of community activities, events, sport, trade, industry and […]

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 […]

Choosing a variable frequency drive or soft starter

When accelerating an AC motor to full speed using a full voltage connection, a large inrush current may be required. Additionally, the torque of the AC motor is mostly uncontrolled and can shock the connected equipment, potentially causing damage. Variable frequency drives and reduced voltage soft starters can reduce inrush currents and limit torque thereby […]

The digitalisation of PV operations

All eyes are on digital technology as European PV plant operators continue to seek meaningful reductions in asset management and operations and maintenance (O&M) costs. Digitalisation promises to slash operational expenses and boost efficiency by automating many tasks that currently have to be done by hand, and by improving asset managers’ ability to rapidly identify […]
