This Research is aimed to design a Solar PV-Battery Based Chicken De-feathering Machine for small and medium scale poultry farmers and entrepreneurs. Farmers or Entrepreneur can process their poultry birds quicker and cleaner to meet the increasing market demand. The machine comprises of mechanical unit which consists of; metal frame, cylindrical plastic drums, rubber plucking fingers, plucker rotor, driven shaft, pulleys, V-belt, base plate, and bearings and also electrical unit which is made of; solar panels, charge controller, batteries, dc-ac inverter and 1HP single-phase induction motor (SPIM). The mechanical system was designed and evaluated using CAD software (Blender). The dynamic performance of PV array, battery system, and induction motor that drives the load (mechanical system and chicken) were modeled and simulated using MATLAB/Simulink and results observed. The induction motor speed and torque as related to daily the sun irradiation and energy supplies from the batteries system were also observed. The proposed model required; simple solar PV, battery based system and inverter for electric power supply, ac motor to convert electrical energy to mechanical energy, cylindrical plastic drum with rubber plucker, plastic rotor and iron bars for framing in order to keep the cost of implementation low. The De-feathering Machine is modeled to be cheap and powered by solar energy system since electricity supply is unreliable and the cost of fuel is substantially high in Nigeria.
