This document summarizes the development of a new solar powered water wheel aerator model, the Chaipattana RX-2-3. The original RX-2-2 model required a 2HP induction motor that was difficult to power with solar cells. The new RX-2-3 model uses a 150W universal motor that can be powered by a single 300W solar panel connected to a DC-DC converter. A new controller was also developed that can operate on input voltages from 100VDC to 55VDC from the solar panel. Simulation and testing showed the new solar powered system can operate for at least 8 hours and has higher oxygen transfer efficiencies than the original model.
