Spanish scientists have proposed a new approach to combine photovoltaic-thermal panels with a reversible air-to-water heat pump in industrial buildings. The system is intended to provide space heating, cooling, domestic hot water, and electricity.

Scientists in South Korea have stressed the importance of accurately setting the angle of slat PV blinds to maximize power generation. They found that there is a tradeoff between elevated power yield and self-shading effects in this BIPV technology.

The Slovakian authorities are offering €140 million ($156.1 million) in rebates for 2023 to cover up to 50% of the cost of buying and installing solar water heaters, heat pumps, biomass systems, solar-thermal collectors, and PV systems up to 10 kW in size.

India will have to add more than 30 GW of solar capacity per year to meet the 293 GW PV target in its optimal energy mix for 2029-30. The nation had installed 68 GW of PV capacity by May 31, 2023.

Dutch utility Liander said this week that the number of curtailment events for residential PV systems more than tripled in the first half of this year, and urged owners of rooftop arrays to expand electricity consumption during peak hours.

Viridian offers five versions of its new residential inverters, with power outputs ranging from 1 kW to 3 kW and an efficiency ranging from 97.2% and 97.6%. The European efficiency is 96.4% to 97.2%.

Qatari researchers have looked at the degree to which cleaning robots reduce PV plants’ yield with the shade they produce on the panels. They found that module orientation has an enormous effect on the impact of shadow.

The adoption of building-integrated photovoltaics (BIPV) has been hindered by the complexity of fire safety standards, creating challenges for manufacturers and suppliers. However, efforts such as the IEA PVPS Task 15 report and collaborative research have shed light on the importance of comprehensive guidelines, reliable testing laboratories, and international cooperation.

In its latest monthly column for pv magazine, the European Technology and Innovation Platform for Photovoltaics (ETIP PV) presents its structures and recent activities. The next outreach activities of the ETIP PV are planned for the EU-PVSEC conference from the 18th to the 22nd of September in Lisbon, covering hot topics like digital PV or updates on levelized cost of PV electricity.

Synergy will offer free electricity to eligible customers, in a move that is designed in part to help counter challenges facing the main power grid in Western Australia.
