Cambodia’s Ministry of Mines and Energy has published a document outlining principles to permit the use of rooftop PV. The new policy replaces a monthly capacity fee for rooftop systems, with a tariff calculated based on an intricate formula.

Germany’s MAN Energy Solutions has supplied two 50 MW seawater heat pumps for district heating at the port of Esbjerg, Denmark. They use CO2 as a refrigerant and will be powered by nearby wind farms. The project will start producing 350,000 MWh of heat per year in the fall.

A survey of more than 2,500 residential heat pump owners and 1,000 gas boilers owners in the United Kingdom shows that 83% of respondents are as satisfied or more satisfied with heat pumps than their previous heating systems in homes built before 1900.

Auxsol’s new three-phase hybrid inverters have efficiency ratings of 97.8% and European efficiency ratings of 97%. They are available in five versions, with power outputs ranging from 5 kW to 12 kW.

The International Energy Agency (IEA) said in a new report that solar will remain the main source of global renewable capacity expansion in 2023, accounting for 286 GW. In 2024, the figure is set to grow to almost 310 GW, driven by lower module prices, greater uptake of distributed PV systems, and a policy push for large-scale deployment.

Maxeon said it has achieved a 24.7% efficiency rating for a full-scale Maxeon 7 solar panel using its IBC technology. The US National Renewable Energy Laboratory (NREL) confirmed the result.

Dutch solar manufacturer Solarge has unveiled two versions of its lightweight mono-PERC solar panels for rooftop applications. The module have power outputs between 470 W and 520 W and efficiencies ranging from 17.4% to 19.2%.

Mitsubishi Electric has launched a demonstration experiment to assess the efficiency of heat pumps in demand-response control on the Aran Islands in Ireland and San Pietro Island in Italy. As part of the European Union’s REACT project, solar, wind, and storage solutions will also be implemented to enhance the energy self-sufficiency of isolated islands.

PV Cycle has published a position paper stating that PV panels do not fit with the European Union’s Waste Electrical and Electronic Equipment (WEEE) directive. It is calling for the implementation of Extended Producer Responsibility (EPR) legislation for all renewable energy products and equipment in the European Union.

Johnson Controls says it will supply four 15 MW heat pumps to the district heating network, in Hamburg, Germany. The new system will be equipped in the city’s central wastewater treatment plant as part of a wastewater heat project.
