Although the Wiki-Solar website ranking only provides a snapshot of PV project engineering, procurement and construction contracts outside of China, it is nevertheless a useful indicator of the changing global solar market landscape. Of the top 11 companies, four are based in India, three in Germany, and two in the United States. But last year’s largest contractor, U.S.-based First Solar, might lose its leading position this year, as it has largely discontinued its EPC activities.

Scientists in Germany have developed a “heavy duty” test to provide insight into the long term effects of potential induced degradation in PV modules. The tests go well beyond those established by IEC standards and seek to guide manufacturers and investors on the best choice of materials – encapsulants in particular – when it comes to long term PID resistance.

The utility-scale PV project, which Belectric built for Fortum Solar India across five sites, is the largest amount of solar capacity that the German EPC services provider has commissioned in the country thus far.

Scientists at Germany’s Helmholtz Zentrum Berlin have made a discovery they say could greatly increase the energy storage capacity of titanium-based ‘MXene’ pseudocapacitors, ultimately leading to faster-charging batteries. The group found adding urea molecules between MXene layers increased the material’s storage capacity by up to 56%.

Fraunhofer ISE researchers have integrated stress and temperature sensors within a PV module. They claim that the devices cover a very minimal part of the cells, and that their interaction with the module and the cell itself is quite limited. The sensors can be manufactured as part of a regular cell manufacturing process.

Product development company the Cambridge Design Partnership, working with compatriot solar business Solivus, has developed a curved solar module featuring an organic thin film. The design is based on Solivus’ desire to “create a product so attractive that people would be happy to have one in their garden”.

The annual global outlook report for solar published by IHS Markit notes there was no real uptick in the amount of new capacity added last year, compared with the returns seen in 2018. That is likely to kill any hope India has of overtaking the U.S. as the world’s second biggest solar market in 2020.

Researchers at the American Institute of Physics have used the clear-sky irradiance model developed by the National Renewable Energy Laboratory to measure the degradation rates of solar panels at a testing field in Germany over five years. The scientists say the model, when combined with real-world data, offers an efficient tool to evaluate the aging of PV technology.

As Germany shuttered another of its nuclear power plants on New Year’s Day, Narendra Modi’s office was said to be considering a proposal which would make coal more competitive with renewables in India.

The pilot plants—installed at a temple and a school—work on a membrane-based electrodialysis technology to provide clean drinking water.
