This week Women in Solar+ Europe gives voice to Maria Ardila, construction engineer at UK-based Cubico Sustainable Investments. She says that progress remains slow in the energy industry because gender matters are often viewed as personal choices rather than the systemic issues they truly are. “Until society challenges the outdated norms and organizational structures that penalize mothers, meaningful advancement toward gender equity in leadership will continue to be constrained,” she states.

Researchers at the National Renewable Energy Laboratory grew tomatoes under translucent solar panels, which could play a promising role in agrivoltaics.

Australian company Solspan has unveiled a 6.4 kW vertical solar wall system for applications in agrivoltaic projects. It measures 4 m x 4 m and can be interconnected with other units to create MW-sized systems.

In grids increasingly dominated by renewables, grid-forming technology is emerging as critical tool for maintaining stability and ensuring reliable power system operation. In this interview with ESS News, Rui Sun, Sungrow’s Deputy General Manager-Grid Technology Center, explains how grid-forming works, why it matters, and where the technology is already proving its value. He elaborates on technical challenges, regulatory gaps, and why grid-forming could soon become the new industry standard.

SunCable has welcomed the Australian federal government’s decision to renew major project status for its Australia-Asia PowerLink, which aims to deliver up to 6 GW of renewable power from the Northern Territory to industries and urban centers in Darwin and Singapore.

Researchers in Europe are investigating semi-transparent solar windows, applying microfabrication technniques to both CIGS and perovskite devices, to overcome the view-impeding properties of earlier solar window concepts.
