Residential PV

The authorities in Arizona have upheld the precedent of capping the reduction at 10% for compensation rates for rooftop PV, following a proposal for a 37% cut. However, there is a possibility of new risks emerging, according to the Arizona Corporation Commission.

India installed 6.8 GW of solar capacity in the first half of 2023, down 15% year on year, according to JMK Research.

Researchers in Morocco have created a new energy management system that allows the combination of rooftop PV with gravity storage. The proposed system is reportedly able to perform smart energy distribution within a household while also lowering electricity costs.

Austria’s Ökofen has developed a residential heat pump that identifies cost-effective and eco-friendly electricity in real time, in order to optimize heat production. It is now seeking a patent for its proprietary control technology.

Donations of cash and solar equipment have thrown a lifeline to schools, hospitals, and communities in Ukraine but the country needs much more, including long-term backing for the recovery of its industry, reports Ian Skarytovsky.

Germany’s 3U Holding AG said its ThermCube heat pump is an ideal solution for new and existing detached and semi-detached houses with a total heat demand of between 6 kW and 11 kW. The new product has reportedly a heat output of 2.33 kW to 8.20 kW and a flow temperature of up to 70 C.

In a new weekly update for pv magazine, Solcast, a DNV company, presents that El Niño will likely bring lower than normal solar power production through winter in the United States. Its analysis is based on data collected from previous El Niño events.

Brazilian scientists have created a new hybrid converter topology based on differential power processing (DPP) that can help reduce power losses in PV systems under permanent mismatch conditions, as well as temporary ones caused by partial shading, dirt and snow. The converter consists of a hybrid topology that combines the PV-to-PV and PV-to-Bus architectures and reportedly solve some of the issues presented by both configurations.

The Indian carbon credit system, operating under the Clean Development Mechanism (CDM) and the United Nations Framework Convention on Climate Change (UNFCCC), stands ahead in several aspects.

Switzerland’s Dhp Technology AG says it plans to deploy new retractable PV systems at 45 motorway service areas in the Swiss cantons of Valais and Bern. The foldable arrays can be retracted and protected during extreme weather conditions or hail storms.
