An experimental project in India is combining solar photovoltaic panels with an irrigation system in an attempt to save water while generating electricity. A 1 MW array has been built over nearly half a mile of the Narmada Canal in the state of Gujarat.
The combination will not only produce electricity but also conserve land and water, according to officials of the state government . The project is meant to show an efficient use of land in an agricultural region by putting solar panels over a waterway rather than over fertile ground. It also should reduce evaporation of the canal water by an estimated 237,750 gallons of water each year. The Gujarat State Electricity Corporation developed the project and hired U.S.based SunEdison to build it.
This is not the first time someone has thought of putting solar panels over water to save space and preserve scarce water supplies. It is still…
