French scientists have proposed the use of radiative sky cooling as a passive cooling technique to cut PV module temperatures by 10 C. They claim the method could improve performance by more than 5 W/m2.

Financiers and investors have always understood that PV power plants play a more prominent role than just generating profits – they also produce electricity without emitting carbon. Lately, the sector is discovering that PV can fulfill a much larger range of environmental functions – improving biodiversity, removing carbon from enriched soils, and producing food in an environmentally sustainable way. Everoze Partner Ragna Schmidt-Haupt argues that putting ecological sustainability at the heart of PV project planning and operation should become the new standard.

Having picked up GBP 5.8 million ($8 million) in a series of investments, U.K.-based Power Roll is pushing ahead with pilot production of an innovative new thin film with which it can manufacture both solar modules and capacitors. In the future, the design could also bring the potential for solar generation and energy storage within a single lightweight device.

A 1.2 MWp installation featuring more than 4,500 solar panels has sheltered a berry crop from high temperatures and damp to strengthen the claims made by agrivoltaics companies that their systems can offer climate change mitigation as well as clean energy.

A new type of carbon fibre and electrolyte matrix stunned scientists when they tested its properties. Their ‘structural’ battery could be used in electric vehicles and could even address the weight problems that bedevil devices planned for electric-powered flight.

The recharging station was designed by French automation group Sirea. It is powered by a solar carport and a small electrolyser.

Dutch research institute TNO has released a series of guidelines to reduce fire hazards in rooftop PV installations. The study follows a series of fire accidents that occurred between 2018 and 2020 in the Netherlands, for which the main causes were identified.

A global ranking of large scale solar project capacities indicates prominent roles for a resurgent Spain, behind the usual top three of China, the U.S. and India, with Australia and the Netherlands also on the rise. There were disappointing returns, though, for the U.K., Italy and Canada.

Russian scientists have developed a holographic film based on prismatic concentrators that reduces the operating temperature of solar panels, including thermal-photovoltaic devices. They claim the patented, low-cost technique can even improve PV module efficiency in cloudy weather.

When coupled to gigawatt-scale solar and wind generation, green hydrogen could be the clean fuel to unlock hard-to-electrify sectors of the economy. But first it must be transported cost-effectively to where it’s needed.
