BHEL tenders grid-connected power conditioning units for 100 MW solar plant in Gujarat
Global bids are invited for supply, installation and commissioning of two sets of 1500V 3-phase grid-connected outdoor PCUs for a 2x50MW solar plant at Raghanesda. Bidding closes on March 7.
Energy efficiency body eyes 1.5 GW of distributed solar within 13 months
Energy Efficiency Services Limited, which has already bagged orders for 800 MW of distributed solar installations in Maharashtra and 113 MW in Rajasthan, says it will roll out 1.5 GW of generation facilities by the end of the next fiscal year.
How do solar cells work underwater?
Although cells lose much of their power yield when submerged, they may not be useless. Researchers in India say submerged cells could be used in monitoring sensors and for other commercial and defense applications. An amorphous silicon cell from Panasonic was tested in their study.
REIL tenders 170 quantities of string inverters
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.
Indian scientists develop multi-level inverter for solar water pumps
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.
Self-healing polymeric coating for photovoltaic devices
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.
Thermal energy giant NLC aims to touch 4 GW solar capacity by 2025
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.

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.
Optimal grid utilization imperative whilst integrating renewable energy
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.
