March 2 is the last date to bid for supply of 5, 15, 20, 25, 30 and 50 KVA string inverters with inbuilt data loggers. Bids will open on March 3. Contract period is up to September 30.

Researchers from the Vellore Institute of Technology have tested a new inverter topology with a single-phase, induction-motor water pump. The seven-level inverter, with five power semiconductor switches, is said to be particularly efficient at reducing switching losses thanks to a pulse width modulation technique.

A new polymer developed by Indian researchers can mend its own cracks when exposed to ultraviolet light. The unique ability makes it an ideal candidate as a smart coating for photovoltaic solar devices to prevent damages and increase performances.

Having touched 1404 MW of renewable capacity as on January 31, 2020, the state-owned producer aims to add further 2847 MW to reach 4251 MW (4 GW from solar and 251 MW wind) by 2025.

Scientists in India have tested a new inverter topology with a single-phase, induction-motor water pump. The seven-level inverter, with five power semiconductor switches, is said to be particularly efficient at reducing switching losses thanks to a pulse width modulation technique.

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.

The Solar Energy Corporation of India should amend the 400 MW round-the-clock supply tender to make co-location of solar, wind and storage mandatory in order to ensure optimal utilization of transmission infrastructure, says NSEFI chairman.

Floating PV has matured quickly, but while the opportunity of solar on the sea may appear immense, there is nothing trivial about the challenges posed by salinity, wind, and waves. However, technical and financial solutions are appearing on the market, giving small island communities a chance to reduce their reliance on polluting diesel.

Cleansolar Renewable Energy, Divine Solren and Neo Solren—all of which were formed to set up and operate solar plants in Telangana—would be sold for around Rs 340 crore. The transaction is expected to be completed by May 31, 2020.

A Turkish research team has analyzed how big changes in temperature can affect absorbance, light transmittance and reflectivity in two types of solar glass. The scientists demonstrated lower efficiency in solar cells and the glass itself were attributable to a large number of micro-cracks and deformations on the glass surface.
