Some 6300 km of canals crisscross the US state of California to funnel water to its rich farmland and cities such as Los Angeles[1].But visitors who travel through California’s Central Valley starting in 2024 will see something unusual near the city of Modesto:Solar panel arrays up to 33 m across covering more than 3 km of the canals snaking through the agricultural area(Fig.1)[2].
