Solar panels bolted over 2 working irrigation canals in California’s Central Valley cut evaporation beneath them by as much as 70 percent, and the aquatic weed that fouls those channels dropped by about 85 percent

"Steel trusses cross a working irrigation canal in Stanislaus County, and rows
of solar panels sit on them like a lid.

The water underneath keeps moving, shaded from the Central Valley sun.

The electricity goes to farms and homes on either side, which was the whole
plan.

The second result was not planned at all.

It is the one that matters more to the people who actually run the canal."
