EnergyBin has released its annual PV module price index, which shows that module prices have fallen from their 2022 peak – but they are still more expensive than they were in 2020.

Germany’s Bosch has developed an air-source heat pump that uses propane (R290) as the refrigerant. It can produce between 3.9 kW and 6.7 kW of heat, and domestic hot water to a temperature of up to 75 C. It says the heat pump can be paired with rooftop solar to maximize self-consumption.

Solitek has revealed plans to build a new manufacturing facility in Benevento, Italy.

Australian materials tech developer Kinaltek has unveiled a one-step production process that it says can convert common silica powders into battery-grade nanosilicon for less than 5% of the cost of existing technologies. The innovation paves the way for the use of silicon nanoparticles in high-performance lithium-ion batteries.

Midsummer and researchers from the University of California, Los Angeles (UCLA), say that their new tandem PV cell is suitable for the company’s Duo production equipment, which makes 56 mm x 156 mm CIGS cells on a flexible stainless steel substrate.

Iberdrola is using a springer spaniel in a solar park to smell electrical problems that could lead to power cuts. It is also using a robotic dog to detect and analyze faults in substations.

Researchers in Singapore have developed a perovskite solar cell via a new method to synthesize the capping without using lead. The cell is capped with a zinc-based compound and reportedly has a conversion efficiency of 24.1%.

Dan French, executive producer of the Solar Farm Summit, told pv magazine USA that more than 500 farmers, manufacturers, and community solar developers likely attended the first US agrivoltaics conference in Chicago last week.

The search for ever higher conversion efficiency has driven solar researchers to focus on back-contact cell approaches, and efforts to devise more cost-effective manufacturing are bringing technologies such as interdigitated back contact (IBC) solar into the mainstream, as Mark Hutchins reports.

Energy Systems Catapult has released interim data from air-source heat pump field monitoring in the United Kingdom between November 2020 and August 2022. Figures show that heat pumps are three times more efficient than gas boilers and that their median coefficient of performance (COP) on cold days is 2.44, compared to 2.80 year round.
