The diagram below shows how a solar powered water pump works. Summarise the information by selecting and reporting the main features and make comparisons where relevant.
The basic working principle of a solar powered water pump is illustrated in the diagram.
Major components of the water pump are solar panel, bore pump, and water tank. Solar panel is fixed on a long post, making sure that it is exposed to adequate amount of sunlight. In the solar panel, photovoltaic cells are embedded, which convert solar energy into electrical energy. The DC current thus generated powers bore pump and water is pumped from the underground bore or well to the water tank placed above ground level. Bore pump is always kept below the water level of the underground source of water. The water pumped and stored in the container can be used for household for agricultural purposes.
As we can see from the figure, to run such a pump, we don't need any input. When irradiated with sun light, the system runs automatically. Since the electrical energy is produced from sunlight, there are no harmful by-products. Thus, this mechanism is absolutely ecofriendly.
