The implementation of aqua-PV is expected to nearly double the rate of land-use efficiency compared to a conventional ground-mounted photovoltaic system, as indicated by studies conducted at Fraunhofer ISE. Currently, one research facility is planned in Vietnam.

The planned system has a capacity of 100 kW and will be equipped with integrated solar modules in a glass tunnel. The PV glass tunnel improves working conditions by shading, provides protection against predation and ensures a stable and lower water temperature to promote shrimp growth. According to initial analyses, the pilot plant is expected to save around 1,500 tonnes of CO2 emissions annually and to reduce water use by 75% compared to a conventional shrimp farm.
