NREL scientists estimate global potential of hydro-linked floating PV at up to 7.5 TW

The U.S. based researchers said linking solar with hydro in a full hybrid system configuration may result – at best – in the deployment of 7,593 GW for an estimated annual power generation of 10,616 TWh and a 20% reservoir coverage. And combining solar with hydro in this way brings further benefits, including improved system operation at different time scales, more opportunities for storage thanks to pumped hydro, increased utilization rates of transmission lines, reduced PV curtailment, and lower interconnection costs and water evaporation.

The long read: Bottom-optimization

With bifacial modules making their way into the mainstream, tracker manufacturers and energy companies are operating test facilities around the world. To drive the LCOE as low as possible, tracker manufacturers now also care about what is happening underneath the modules, and not just above. As the power comes from light reflected from the ground, increasing that reflectivity has been mooted by many stakeholders. This is not without complication, however, and the quest for optimization goes into the next round.

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.
