Daiwa House, Japan’s largest homebuilder, has developed a new carport made from extruded aluminum profiles. It comes in two versions, accommodating either four or two vehicles.

The Taiwanese government has introduced a new, favorable framework for renewable-energy power purchase agreements (PPAs). Large energy consumers are no longer required to buy the entire output of large-scale facilities.

Researchers in Italy have conceived a dual-source heat pump system that uses both a finned-coil evaporator and a solar evaporator made with three photovoltaic-thermal panels. Thanks to the combined action of the two evaporators, the heat pump can achieve higher evaporation pressure and coeffficient of performance.

New research from Germany shows that investing in residential PV remains an optimal choice even when price breaks on electricity and natural gas are applied. The scientists quantified the savings that PV systems achieved between 2019 and 2022, when the COVID-19 crisis and the outburst of the war in Ukraine made prices in the electricity markets extremely volatile.

The novel propane heat pump has a coefficient of performance of up to 4.9 and can reportedly achieve a flow temperature of up to 55 C.

A Qatari research group has analyzed the performance of polyethylene terephthalate backsheets in real outdoor testing conditions in desert areas and has identified the main causes that lead to degradation. These include prolonged exposure to high ultraviolet radiation, high operating temperature cycling, and relative humidity.

Authors of the World Nuclear Industry Status Report 2024 the world had 408 operational reactors producing 367 GW in the middle of the year, which is significantly less than installed capacity predictions for solar by the end of the year and five time less the world’s cumulative PV capacity, which is now approaching 2 TW.

A number of solar arrays were reportedly involved in a second wave of electronic-device explosions across Lebanon yesterday, resulting in numerous injuries and deaths. On Tuesday, an initial series of blasts triggered by pagers targeted members of the Hezbollah militant group, but also affected civilians.

The novel heat pump can reportedly heat air to up to 49 C. Its full-load heating capacity is of up to 63,000 Btu/hour.

Researchers in China have proposed a new lithium-free doping strategy to fabricate spiro-OMeTAD-based hole transport layers (HTLs) for applications in perovskite solar cell. A PV device built with a salt-doped HTL achieved a record-breaking efficiency of 25.45%.
