Sažetak
Usage of solar photovoltaic energy, not only in urban water supply systems, but also for irrigation has special importance for the entire human population on the world. Even if location has a sufficient quantity of water, it should be noted that electricity supply for its abstraction, further distribution and use can be a problem. Photovoltaic energy is particularly suitable for energy supply for irrigation in rural areas because there are locations where classical power network is not available or has limited availability. In this situation, especially in remote areas and on islands, Photovoltaic energy solves this energy and water distribution problem. Also, using of Photovoltaic energy contributes to the reduction of greenhouse gasses. In doing so, the emphasis is not only on the use of Photovoltaic energy, but also on improving of the performance of pumping stations and reservoirs, as well as the remaining parts of the water supply system. The abovementioned solution is sustainable, given the economic, environmental and social indicators, which is achieved by using original and innovative scientifically method, i.e. Critical Period Method. Critical Period Method includes design elements of the solution: Photovoltaic system, Pump station and Water reservoir based on the critical period of operation of each one. By using of solar photovoltaic energy, electric energy is produced and used for operational work of the pumping station. Pumping station pumps water into the water reservoir. From the water reservoir, water is distributed to the irrigation pipelines on the irrigation area. The balancing period of water pumping and water consumption (water and energy balance) is usually at least one day and may be several days, usually no more than five. Also, intention of this paper is to prove that the water reservoir with its usual hydraulic role of storing water also has the function of energy reservoir through the possible functional connection with the source of energy, which is in this case subsystem Photovoltaic. Such this kind of methodology so far hasn’t been applied anywhere in the world. Case study on the example of irrigation for agronomy purposes will present application of the mentioned method.
