Sungrow signs 650 MW PV inverter supply deal with Avaada Energy

The Chinese inverter manufacturer will supply its 1500V 3.125 MW central inverter solution for Indian developer Avaada Energy’s upcoming PV projects in India.

Covid-19: Discom revenue dip could spell trouble for PV producers

Sliding electricity demand and declining commercial and industrial activity could prompt distribution companies to block or delay payments to solar power producers.

Analyst expects recovery for PV and storage supply chains

U.S.-owned analyst Wood Mackenzie expects solar demand to decline but predicts the market will recover, with the prospects for the energy transition remaining intact.

Evaluating battery chemistries for grid-level storage

Researchers in China have ranked some of the most commonly used battery chemistries according to parameters deemed important for grid-level storage. The team gave a score in each category and determined a winner – and it wasn’t lithium-ion.

Recycling lead-acid batteries for perovskite solar cell manufacturing

Researchers from China are proposing to use spent battery lead for creating a perovskite that can be used in the production of solar cells that are based on this promising material. The proposed one-step process, which was tested in the production of a 17.38% efficient perovskite heterojunction cell, is said to be cheaper and less energy-intensive than other recycling processes for waste lead from lead-acid batteries.

USA: Government report says Trump’s solar tariff has accomplished little

The U.S. ITC has released a report highlighting changes in the domestic solar cell and module manufacturing industry, showing that while there has been an increase in domestic module manufacturing, the overall program’s success, relative to the $740 million in tariffs, has created little measurable benefit.

Solar projects reprieved as Indian government declares coronavirus a force majeure

Lobby group the National Solar Energy Federation of India says around 4 GW of solar plant capacity is likely to be affected by component shortages after the outbreak of the virus in China.

3 GW Indian solar projects at risk due to Coronavirus, says CRISIL

Delay in sourcing of PV modules from China can cause project cost and time overruns, inviting penalties for missing the commissioning date.

The long read: Go big, go with the flow

While lithium batteries have taken center stage for energy storage, vanadium redox flow batteries could gain considerable traction in 2020. In previous years, vanadium battery installations around the world have done little more than provide proof of concept and a test bed for manufacturers, argues David Gillam from Mastermines. He looks at what may have changed since then and why a surge in batteries utilizing vanadium may be closer than many believe, with China taking the lead.

Coronavirus could cost Chinese battery makers 26 GWh of output

WoodMac analysts say the amount of new battery manufacturing capacity added in the nation this year could fall by as much as 10% because of the outbreak. With Tesla’s Shanghai gigafactory affected by the extended new-year-holiday shutdown, the analyst warned of potential supply shortages for Australia and the U.S. and U.K.
