The long read: Packing light

Tens of thousands of health facilities in low- and middle-income countries lack reliable electricity, contributing to high rates of maternal mortality. Health workers struggling in near darkness use candles, kerosene lanterns, or cellphones to provide illumination for critical procedures. They ask patients to pay for candles, batteries for flashlights, or kerosene for lanterns – a barrier to health care for women living in extreme poverty. We Care Solar designs and delivers pre-wired compact Solar Suitcases for maternal health care facilities in the developing world. This all-in-one solar+storage solution for childbirth evolved from a doctoral student’s research project, and is being scaled worldwide to ensure that no woman gives birth in the dark.

REIL seeks 1.2 million multi-crystalline silicon solar cells

September 24 is the last date to submit bids for supplying 1.2 million quantities of multi-crystalline silicon solar cells, half of which is tendered under the domestic content requirement category. Cells are required in peak power ratings of 4.50W (4/5-busbar), 4.60W (5-busbar) and 4.67W (5-busbar).

Rajasthan could add 22.6 GW of new renewable energy capacity to the grid within a decade

The state—which has already installed an aggregate 9.6 GW of renewable energy capacity as of FY 2019-20 end—will add another 22.6 GW to the grid by the end of FY2029-30. Of the new RE addition, 18 GW will come from solar capacity.
