In the third week of September, European electricity markets prices fell compared to the previous week. The decline was due to lower demand and a significant increase in wind energy production in several markets, which offset increasing gas and CO2 prices. On September 25, TTF gas futures reached their highest level since early April and on September 18, Brent reached its highest settlement price since November 2022.

Ireland’s Department of the Environment, Climate and Communications and network operator EirGrid has revealed the 20 solar projects totaling 497 MW that were provisionally selected in the latest auction round of the country’s onshore Renewable Electricity Support Scheme (RESS). The procurement exercise concluded with an average strike price of €0.10047($0.10596)/kWh.

Gautam Solar says it will invest $18.1 million to double its annual PV module production capacity to 2 GW.

Solar industry veteran Jigar Shah, the director of the US Department of Energy’s (DoE) Loan Programs Office, says that virtual power plants are the path to success, as solar net metering now faces an uncertain future.

SolarPower Europe said in its latest report on EU solar jobs that the European solar industry employed 648,000 people at the end of 2022, up from 466,000 the year prior. It said the sector will reach 1 million full-time employees within three years.

Scientists in Australia have proposed to use a a propeller pico-hydropower turbine to recover the energy used for pumping water in a solar-powered commercial building. They have found that the mini hydro system is a relatively low-cost solution, able to recover approximately 10% of the energy used for pumping seawater.

Scatec has turned on two solar-plus-storage facilities in northern Cameroon, with 30 MW of solar and 20 MW/19 MWh of energy storage.

Fluke aims to take the PVA-1500HE it acquired from Solmetric to the global market. It claims the new hardware will fill a gap in the worldwide market with a U.S.-preferred tool.

Researchers from Germany’s Fraunhofer ISE developed new techniques to reduce silver consumption in tandem perovskite silicon solar cells and heterojunction silicon PV devices. The new processes relate to cell metallization and module interconnection.

Researchers in Iran have designed a new light trapping (LT) structure for perovskite solar cells that reportedly achieves optimal light absorption without impacting the electrical properties of the cells. The key element of the device is an anti-reflector layer based on silicon dioxide (SiO2) that improves light harvesting and charge extraction performance.

Carbon electrode back-contacts for perovskite solar cells promise simpler, less energy-intense manufacturing, but low power conversion efficiency has held back adoption. However, this may change now, as researchers are overcoming the barriers to commercialization.

A fire broke out this week in a Tesla Megapack 2.0 battery unit at the Bouldercombe battery facility in Queensland, Australia.

Abu Dhabi-based Masdar and PLN Nusantara Power, an Indonesian state-owned electricity generator, have agreed to more than triple the size of the Cirata floating PV power plant in West Java so it can generate 500 MW.

This week, Longi and TCL Zhonghuan reduced slightly the prices of their wafer products. Meanwhile, the China Photovoltaic Industry Association reports strong ouput growth for the solar industry.

An international research group has analyzed a vertical bifacial agrivoltaics system in a drought-stricken part of Chile. They say that the solar array can improve water efficiency for crop irrigation, while the vertical system configuration optimizes PV power generation throughout the day, minimizing curtailment.

The Chinese manufacturer said TÜV SÜD confirmed the results. It launched the G12 series of heterojunction solar modules, with a focus on utility-scale projects, in the second half of 2022.

UK researchers have developed ultra-thin nanoribbons, just 1 atom thick, by combining phosphorus and arsenic alloys. The nanoribbons offer excellent conductivity, even at temperatures exceeding -143.15 C, and have the potential to enhance charge flow in solar cells.

Sunmaxx PVT, a photovoltaic-thermal solar module specialist, has started building an automated 50 MW module factory near Dresden, Germany.

LG Energy Solution will soon release its lithium iron phosphate batteries in the European market, featuring compatibility with single-phase and three-phase inverters. The South Korean manufacturer will offer two configurations, with capacities of 12.4 kWh and 15.5 kWh.
