Dyness releases 1.6 kWh battery for balcony PV systems
Chinese manufacturer Dyness has unveiled a 1.6 kWh battery designed for balcony PV systems, allowing users to stack up to four units for a total storage capacity of 6.4 kWh, with a reported lifespan of more than 8,000 cycles.
Using air conditioning to cool down PV modules, dry dishes
An international research team has investigated how air conditioning may be used to reduce the operating temperature of PV panels. The researchers not only found that the proposed approach is technically viable, but they also tested the use of excess heat from the panels for drying dishes.
PV-driven microgrid for hydrogen, cooling
The University of French Polynesia has built a PV-driven hydrogen generation unit that combines a hydrogen chain with a thermochemical unit. The latter is used to recover waste heat from the electrolyzer and fuel cell to enable deferred cooling production for air conditioning.
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.
