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.
A multi-level inverter for solar water pumps
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.
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.
Assessing the impact of micro-cracks in solar glass
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.
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.
Raising crops in PV facades
An international research group has analyzed the visual impact of PV facades on buildings which include crop cultivation. Architects, PV specialists and farmers were surveyed and the results showed broad acceptance of such projects.
BHEL wins battery energy storage system order for Delhi discom-TERI pilot
By offering 410 KWh of cumulative battery capacity for a total cost of Rs2.51 crore, the state-owned engineer and manufacturer emerged winner in the auction which saw overwhelming response from both Lithium-ion and advanced lead-acid storage providers.
Waaree signs MoU with Gujarat to set up Rs 11 billion solar modules and cells plant
Coming up at Moda village in Valsad district, this will be Waaree’s third solar modules investment in Gujarat after Surat and Umargam plants.
Large scale storage still some way off
Consultancy Bridge to India has looked into its crystal ball to predict India will add 10 GW of solar capacity this year and the same next year before deployment slows to 7 GW per year in 2022 and 2023, dogged by hurdles such as an inexplicable ongoing demand for new coal-fired power plants.
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.
