For this type of irrigation, we can use a multi-pump system with raft where the pumps will work simultaneously distributing the energy available in the solar panels.

The surface pump is always going to run at constant pressure and flow, supplying water to the pivot or the cover system. The submersible pump will increase or reduce its flow rate depending on the solar energy left over at each moment for the filling of the raft. An alternative to the multi-pump system is to use a single over-sized submersible pump and where we use a maximum power point tracking system for solar panels. This system is optimal for large risks such as irrigation with pivot or cover.
