We use solar energy to meet our electricity requirements to operate motorized valves. Through Solar Photovoltaic cells, solar radiation gets converted into DC electricity directly. This electricity can either be used as it is or can be stored in the battery. This stored electrical energy used to operate motorized valves.In auto mode, the valve operates by mobile phone through GSM network. If you give the Open command message, the Valve opens and if you give the Close command message, the Valve Closes. The Valve OpenClose indications glow respectively.
