Clever-PV has developed a manufacturer-independent energy management solution for homes. The app is free to download from app stores and can be connected to PV systems, wall boxes, heat pumps, and other smart devices. This allows users to optimize the use of self-generated solar power.

Scientists in Italy have developed a 5 kW direct-expansion solar-assisted heat pump that uses alternatively two different evaporator technologies. The cooling of the PV module unit by CO2 evaporation increases power production by 8%.

The hail storms that occurred recently in northern Italy damaged several photovoltaic systems. pv magazine Italy retrieved a report from the Vrije Universiteit Amsterdam from 2019 which tried to shed light on the damage caused to solar installations by hail by analyzing the effects of a severe hailstorm that occurred in the Netherlands in 2016. According to their assessments, damages to PV modules are mostly derived from hailstones of at least 3 cm in diameter.

Researchers in China have found that the addition of serine cations to the electrode/electrolyte interface of aqueous zinc-ion battery could effectively inhibit zinc dendrite growth and enable a highly reversible zinc anode.

Researchers in Canada have found that nearly zero-energy buildings (NZEBs) with on-site solar energy generation should not exceed an energy use intensity (EUI) of 50 kWh/m2a, which they said corresponds to a maximum of 10 floors. They also ascertained that the maximum permitted EUI by net-zero energy status is 17–28 kWh/m2a.

A study by TÜV Nord in Malaysia shows that the latest generation of tunnel oxide passivated contact (TOPCon) modules surpass their older rivals on energy yield. The researchers compared n-type TOPCon modules with older p-type PERC modules, both manufactured by JinkoSolar over a three-month period earlier this year. The newer product showed an energy yield 5.69% higher than its PERC counterpart.

Indian developers have completed 11 solar parks, aggregating to 8.521 GW, and have partially completed seven solar parks, totaling 3.985 GW, under the Indian Ministry of New and Renewable Energy’s scheme for the development of solar parks.

India deployed 6.8 GW of solar in the first half of 2023. The rooftop solar segment had 2,294 MW of capacity additions, which is higher than the total rooftop PV installations recorded in 2022.

Researchers at Argonne National Laboratory and the US National Renewable Energy Lab (NREL) have found that renewable energy can reduce the cost and emissions of electricity in remote parts of Alaska.

South Korea’s SDN has developed new bifacial solar modules based on M10 wafers. The new products feature a power conversion efficiency of 21.46% and, according to the manufacturer, are the world’s most efficient floating PV panels.
