A Jordanian research team has designed a cleaning technique for solar modules that uses static electricity to remove dust from panel surfaces. The system features an electrostatic ionizer that reduces attraction between dust particles and their accumulation on modules, improving their energy yield.

IEA-PVPS has used an improved methodology to determine that newly installed PV capacity in 2022 must be somewhere between the 190 GW calculated by the International Renewable Energy Agency (IRENA) and the 268 GW announced by BloombergNEF. Its new “Snapshot of Global PV Markets 2023” report was built on data from a range of sources, including grid-connected and off-grid figures.

Dutch startup Airturb has developed a 500 W hybrid wind-solar power system featuring a vertical axis wind turbine and a solar base hosting four 30 W solar panels. The system can be used for rooftop or off-grid applications.

With copper prices rising, inflation driving up the cost of living, and organized criminal gangs stepping up operations in the United Kingdom and across Europe, solar project owners need to be more conscious than ever of security.

TrendForce has ranked the top six module manufacturers by shipment volume in 2022, with Longi topping the list, followed by Trina Solar and JinkoSolar. JA Solar, Canadian Solar, and Risen Energy rounded out the top six, in a year dominated by large-format modules.

Sarcos has designed a robotic PV construction solution that delivers, detects, lifts, and places PV modules in large-scale solar plants. It has recently field tested and validated the prototype solution in a pilot project funded by the US Department of Energy.

The debate continues over whether super-sized, high-power solar modules are a good thing for the industry and they appear to be here to stay. Vicente Parra and James Whittemore, from Enertis Applus+, consider the pitfalls to avoid when designing high-power solar projects.

The US National Renewable Energy Laboratory (NREL) and First Solar have used cracked film lithography (CFL) to build a bifacial cadmium telluride solar cell with a power density of 20.3 mW cm−2. They claim the cell has a higher bifacial power density than any polycrystalline absorber currently manufactured at scale.

Israeli company Brenmiller is set to launch a 4 GW to 5 GW production line for its thermal energy storage systems, which use crushed rocks to retain heat that can be released as steam, hot water, or hot air.

Stanford University researchers have created a model to assess how much compressed air storage capacity might be needed for the deep decarbonization of power systems, while compensating for the variability of wind and solar-based power systems. They applied the model to California’s energy system and found that compressed air could be very competitive on a dollars-per-kilowatt-hour basis.
