The government will grant rebates to residential PV projects and may cover up to 90% of the costs of purchasing and deploying a rooftop array.

A global research team says that China’s PV poverty alleviation scheme has ramped up disposable income levels in the country’s poorest counties. The Chinese government aims to install more than 10 GW of PV, especially in the most impoverished parts of eastern China, to help 2 million people by the end of this year.

Researchers in Germany have identified salt caverns as a feasible and flexible solution for hydrogen storage. They also revealed that Europe has the potential to inject hydrogen in bedded salt deposits and salt domes, with a total storage capacity of 84.8 PWh.

According to the Chinese power electronics manufacturer, the series features a maximum input voltage of 1,100 V per string and efficiencies ranging from 98.6% to 99.0%.

Scientists in the Netherlands have demonstrated an interdigitated back contact copper-indium-gallium-selenide solar cell with a sub-micron thickness of 673nm. The device has an aluminum oxide and magnesium fluoride-based anti-reflective coating.

The government said developers have one more month to apply for the subsidy. It also delayed the project-completion deadline from Dec. 31, 2020, to June 30, 2021. From next year, rooftop PV will likely be supported by unspecified tax breaks.

The new measure mainly applies to wind power and other renewable energy sources, as most of the country’s solar capacity was deployed after 2014, when the energy reforms were implemented.

European scientists have developed mini modules with an active area of 14 cm² and a 3.68% efficiency rating. The panels also have a self-adjusting feature that can help to mitigate the amount of light when they are exposed to full sunlight, or to the temperatures of buildings with large windows and/or glass facades.

The Italian cabinet has accepted a request from the Ministry of Cultural Heritage and Activities to cancel approvals granted by the Lazio regional government for two large-scale PV projects. Lazio’s Tuscia area is a potential solar hub for the Italian energy system.

The pilotless, high-speed solar boat, now under development by Russian scientists, purportedly has unlimited power reserves. It could be used for marine patrols, search and rescue operations, and cargo delivery, they said.
