In a new weekly update for pv magazine, Solcast, a DNV company, reports that variations in weather patterns, including El Niño and regional droughts, shaped solar energy performance worldwide last year.

Uttar Pradesh New and Renewable Energy Development Agency (UPNEDA) has started accepting expressions of interest (EOI) from developers to set up floating solar projects on a build-own-operate basis in India.

A British-Swedish research team has reviewed all models for designing and simulating solar-powered heat pumps systems of various complexities. Based on this work, the scientists proposed a new method combining five models across multiple computer programs into a single analysis tool that reportedly produces accurate critical metrics for technical, economic, and climate impact analysis.

University of New South Wales researchers investigated the impact of sodium-induced degradation in heterojunction solar cells under accelerated damp-heat testing. They considered three different types of sodium salts and identified the degradation mechanisms attributed to each contaminant.

The reason given for the shutdown is the inability to “improve the level of some key impurities,” and would not be able to deliver a quality product in the time demanded by the company’s main customer.

The International Energy Agency’s (IEA) Photovoltaic Power Systems Programme (PVPS) highlights key performance indicators (KPIs) for PV systems in its latest report. It calls for clear KPI definitions and standardized data handling to enhance system efficiency and reliability.

As the penetration of variable renewable energy increases, curtailment of solar PV generation will only increase. Since curtailment will almost always be cheaper than investing in new transmission capacity or new grid-scale storage, curtailed energy should be rewarded, so that PV investment decisions can include curtailment as one of the flexibility options for grid operators.

The US National Aeronautics and Space Administration (NASA) has published aerial images of the Great Solar Wall, China’s largest renewable energy project. The installation is expected to reach 100 GW of capacity by 2030.

Researchers in China claim to have built a perovskite solar cell that can effictively reduce ion migration and offer superior stability. The device utilizes an ultrathin membrane made of a polymeric material known as PDTBT2T-FTBDT (D18), which reportedly offers conformal coverage on the surface of perovskite film due to its high fluidity.

Adani Renewable Energy, Adyant Enersol (Datta Infra), Ampin Energy, Green Prairie Energy (EverGreen Power) and JSP Green (Jindal Renewables) have won in NTPC’s latest auction for 1.2 GW of wind-solar hybrid capacity in India.
