New MPPT approach for multi-string PV systems under partial shading
Egyptian researchers have developed a multi-string PV system with a converter control strategy, achieving 99.81% efficiency with a direct duty cycle for maximum power point tracking (MPPT).
SAJ releases new battery inverter series for residential applications
China’s Guangzhou Sanjing Electric (SAJ) has developed two new single-phase and three-phase all-in-one battery inverters with efficiencies of 97.8% and 98.0%, respectively. They use artificial intelligence to support energy management.
Collectively owned PV systems improve energy community performance
Researchers have looked into the impact of potential regulated charge exemptions on two types of energy communities in 39 European countries. They have found that communities with collectively owned PV systems achieve greater savings.
Photovoltaics for biomethanation
Researchers in Denmark have studied the technical and economic feasibility of biomethanation through large-scale PV power generation. They said that the intermittent PV-driven biomethanation process matches the efficiency of continuous processes after several days.
Open-source workflow to assess rooftop PV potential
Scientists in Germany have developed a new open-access approach to assess regional rooftop PV potential. The ETHOS.PASSION approach combines two deep learning models to identify rooftops and superstructures.
Monoprice unveils new PowerCache batteries with up to 1,000 W of output
Monoprice, a US consumer electronics supplier, says its new portable batteries can store electricity from solar panels and wall outlets. They range in price from $199.99 to $799.99.
Satellite method estimates albedo for bifacial PV systems in ‘worst-case scenario’ areas
Scientists in the UK have utilized data from two different satellites – Sentinel-2 and MODIS – to develop a new and more accurate approach to estimated albedo for bifacial PV systems in complex landscapes. The novel methodology reportedly achieved a much lower normalized root mean square error than reference methods relying on MODIS only.
Algae photovoltaics for hydrogen production
South Korea researchers have developed a cell by merging green algae with carbon nanofibers, in order to generate 9.5 W per cell and achieve a peak efficiency of 0.9%. They claim this is enough to power a micro-generation system for hydrogen production.
LG targeting Alaska for heat pump deployment, research
LG has formed a partnership with the University of Alaska Anchorage to conduct lab research and perform real-world testing of heat pump technologies, with a particular focus on Alaska’s extreme temperatures.
