The project describes the development of a hydroponic system using solar panel to control light and water pump using an automatic time controller and also to minimize operational cost up to 40 %, to maintain continuity of renewable energy source and to release dependency from electric utility. Solar power is ideally used in India due to location factor and also gives the benefit to the environment as renewable energy. The solar assisted hydroponic green fodder gadget consists of solar panel, battery, micro sprinklers and automatic time controller. The collected solar radiations are converted into electrical energy and stored in battery with an average output of 12V while maximum output voltage of 18V. The growth of the fodder crop mainly depends on moisture, temperature, RH and irrigation. Hence an automatic time controller is used to control the operation of hydroponic system for switching water pump, battery charge, discharge state and automatic micro sprinklers will be used to control moisture, temperature, RH and irrigation. The 10th day fodder is harvested and laboratory test were carried out to study the content of crude protein, crude fiber, ether extract, total ash and acid insoluble ash and moisture content. Test revealed that crude protein (%) 13.2, ether extract (%) 3.3, crude fiber (%) 15.02, total ash (%) 2.35, acid insoluble ash (%) 0.33 and moisture content (%) 83.87. The increased nutritional content may be due to increased conversion efficiency. It is observed that during normal climatic condition the PV module produced power in the range of 7.1 to 17.29W from 10:00 am to 04:00 pm in the month of April and May.
