New machine learning tech for short-term PV power generation forecasting

Researchers in China have applied a machine learning technology based on temporal convolutional networks in PV power forecasting for the first time. The new model reportedly outperforms similar models during all seasons.

Improving silicon solar cell performance with aluminum-doped polysilicon passivating contacts

An international research group has developed a novel technique enabling the creation of contacts at low temperatures. The novel contact types are reportedly able to enhance cell efficiency by up to 3%.

The solar rebound effect in residential PV

The rebound effect consists of a reduction in expected gains from a more resource-efficient technology as a result of behavioral or systemic change. An international research team has investigated this phenomenon in the residential PV segment in Vietnam and has found that it could happen in any country where the policy supporting solar power is not fully and scientifically explained.

Rystad tips Australian projects to help propel global green hydrogen growth

Rystad Energy has countered the International Energy Agency’s (IEA) recent “reality check” for the green hydrogen sector, predicting that the momentum behind renewable-based hydrogen will gather pace in 2024 as global renewable energy capacity continues to expand rapidly.

Rio Tinto signs long-term PPA for 1.1 GW Australian solar plant

Resources giant Rio Tinto has signed Australia’s largest corporate power purchase agreement (PPA) to date. It has agreed to buy 100% of the output from European Energy Australia’s 1.1 GW Upper Calliope Solar Farm to provide renewable power to its aluminum operations in the state of Queensland.

Optimal tilt angle for agrivoltaic projects in Mediterranean region

Scientists in Turkey determined the optimal tilt angle for agrivoltaic projects associated with different crops in the central Mediterranean region, and other regions with similar latitude and climatic conditions.

Researchers apply thresholding to PV soiling image analysis

Thresholding methods have commonly been used to characterize the soiling accumulated on glass coupons. Researchers led by the Sapienza University of Rome have identified 16 automatic thresholding methods that may be used for analyzing soiling on PV panels.

Cohuna solar plant resumes operations after Energy Safe shutdown

Renewables developer Enel Green Power Australia has confirmed that its 27 MW Cohuna Solar Farm in the Australian state of Victoria has resumed partial operations after being forced to shut down following a grassfire at the site in November.

How to integrate residential solar-plus-storage with vehicle-to-home systems

Researchers from Australia have created a model to optimize the interaction between vehicle-to-home (V2H) systems and residential PV connected to battery storage. They claim V2H can help reduce the cost of energy by 16.7% for workplace charging and 25% for public charging.
