The two companies have glued 230 square meters of solar film to the rough concrete surface of a grain silo in Donauwörth, Germany. The film is expected to generate approximately 6,700 kWh kilowatt-hours of solar power per year. Lechwerke and Heliatek want to open up new potential for the use of PV on other surfaces with the pilot project.

According to a paper published by the European Network of Transmission System Operators, a significant number of grid infrastructure projects in the Ten-Year Network Development Plan 2018 have been delayed, with public opposition identified as the main hindrance.

A new study conducted by an international team of scientists from leading institutions in the U.K. and the United States provides an explanation as to how the addition of selenide can greatly improve the efficiency of cadmium telluride solar cells. Explaining the performance boost will provide researchers with a route to explore further efficiency improvements, pushing the material’s cost even lower.

Perovskites and quantum dot solar cells both have potential for use in high efficiency PV devices, but have major challenges to overcome to be a commercial reality. Scientists at the University of Toronto have found that if the two technologies are combined in the right way, they can stabilize each other.

While preparing for the country’s first, 1.35 GW solar tender in June, state secretary for energy João Galamba has revealed another procurement exercise will be held in January and rejected criticism next month’s auction has been badly designed.

The Institute for Energy Economics and Financial Analysis has estimated the effect on the payback period of PV systems when adding EVs and storage in Germany and Britain. In both cases, system owners are likely to reduce their payback period by significant margins as increased self-consumption can offset the incremental phase out of government incentives.

What was originally a landmark bill to establish rights for the owners of PV systems has made it to the floor of the California Senate in a dramatically reduced form.

Long awaited – and even longer debated – the 1000 pages of legislation have finally been adopted by all EU institutions. Over the coming 18 months, there will be changes, some big, some small, to the markets in Europe. Across the continent, the renewable energy industry is likely to benefit.

Researchers at the University of California, San Diego – with the help of the university’s Comet supercomputer – modelled thousands of halide compounds to come up with a shortlist of 13 materials that could be candidates for the efficient solar cell materials of the future.

The solar-plus-storage combination is super-charging the deployment of batteries across the country and IHS Markit says the U.S. will become the largest market for grid-tied energy storage this year.
