Intelligent Control System for Solar Power Complementing with Grid Power

In the energy-saving schemes proposed earlier, the basic idea is to complement the existing pump running on a grid that consumes energy beyond expectation with the new generation devices that are smart in operation and saving. Solar panels are installed that would give enough energy to run a 2 HP pump, and water level sensors are fixed on the overhead tank for three different levels. These lower sensors detect the low water level and automatically switch on the pump running on solar power. Once the tank is filled, the high-level sensor activates and switches off the solar pump. If there is not enough solar energy available (rainy or cloudy days), and the water level is low in overhead tanks, the pumps are switched to grid power. However, the tank is not filled until the water level is medium. Sending and receiving of the transmission data is done through wireless communication to avoid the extra cables running. Features like accurate water level detection, Better Closed loop control, Effective timer control, Remote control for timing and feasibility of mode changing are introduced into the old Energy guzzlers.
