The California Public Utilities Commission (CPUC) has prohibited the use of battery-tied solar exports to offset delivery charges, following its decision to slash the value of standalone solar exports in order to encourage the pairing of systems with battery storage.

A US research team has tested mini solar modules in marine data collection devices, using animal hosts for water column profile measurements. The findings suggest that submarine PV can effectively operate in these applications at depths of up to 22 meters.

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.

California plans to shift 3 GW of load from dirtier, more expensive times of day to cleaner, less expensive times by setting flexible demand standards for many types of electric appliances. Global interest in California’s work is high, according to a state agency commissioner.

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.

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.

A US research group has developed stable emitters for high-temperature applications above 1,800 C, which could improve the efficiency of lab-scale thermophovoltaic systems. The framework showcases the potential to design application-specific metamaterials in high-temperature photonics using optimization and machine learning.

A research team in the United States has created a novel approach to integrate raw sky images and global solar irradiance measurements, solar nowcasting, and intra-hour forecasting. The methodology utilizes low-cost radiometric IR cameras instead of expensive ceilometers.

For those who combine solar, batteries, and electric vehicles (EVs) at home, driving on sunshine is a realistic goal. However, there are many factors to consider when analyzing the economic payoffs, as well as the technical possibilities and limitations of such systems.

The International Energy Agency has warned that lagging policy support, rising costs, and supply chain disruptions threaten the profitability of low-emission hydrogen, while the Commonwealth Scientific and Industrial Research Organisation (CSIRO) has identified hydrogen seeps in South Australia.
