Complementary hybrid PV systems can reduce reliance on storage

Looking back over years of research into the topic of hybrid systems based on different combinations of solar, wind, hydro and other renewables, an international group of scientists found strong potential for strategies to exploit complementarity between the different sources integrate more intermittent renewables onto regional and national grids. The scientists present a series of conclusions and recommendations that aim to push research in hybrid renewables forward.

Saving water with solar and wind

Scientists at Princeton have found solar and wind energy offer the added environmental benefit of reducing water usage, by comparison with hydroelectric dams. Their findings, say the researchers, could have a positive impact on groundwater sustainability in drought-prone regions such as California, where they conducted a case study.

The German multinational signs memorandum of understanding with Dubai Electricity and Water Authority to build pilot the facility at the vast 1 GW Rashid Al Maktoum Solar Park.

Solar panels for world’s first combined hydro & floating PV project installed in Portugal

French floating PV specialists Ciel & Terre have installed a 220 kW PV installation at a hydroelectric dam on Portugal’s Rabagão River. Though a comparatively small installation, this represents the first time the two technologies have been used in tandem at utility scale.
