TECHNICAL FIELD
The present disclosure relates to a system and method for utilizing heat energy to harness electricity.
BACKGROUND
With an increase environmental pollution all around the globe, a need of using eco-friendly power generation systems has arisen. Out of the available eco-friendly power generation system, solar energy is the most promising and eco-friendly power generation system.
Harnessing solar energy using solar panels is a promising eco-friendly power generation system. However, overheating of the solar panels is the biggest problem causing inefficiency in power generation using the solar panels. The conventional way to overcome the overheating problem is spraying of water on the solar panels. But, the residual water is further unutilized and causes huge water wastage.
The other biggest problem with the solar panel power generation system is the intermittent electricity generation. The cause of intermittent nature of electricity generation is the variation in seasons, geography, sunlight exposure on the solar panel, etc. This makes a strong case of integrating the solar panel system with some other eco-friendly power generation systems.
Therefore, in light of the aforementioned drawbacks and several other inherent in the existing arts, there exists a need to provide a system for integrating the solar panel power generation system with some other eco-friendly power generation system. There also exists a need to provide a system which integrates the solar panel power generation system with some other eco-friendly power generation system and utilizes the residual sprayed water efficiently.

Example embodiments of the present disclosure are described below, as illustrated in various drawings in which like reference numerals refer to the same parts throughout the different drawings.
The present disclosure relates to a system and method for generating electricity from water sprinkled on a solar panel water for cooling purpose.
Fig. 1 illustrates a system [100] integrating a solar panel with a heat exchanger and reutilize water used in cooling of the solar panel. The system [100] comprises a water tank C [120], a water tank A [140], a solar panel [160], a trough collector [180], a filter [200], a water tank B [220], a heat exchanger [240], a turbine [260], an energy storage/auxiliary consumption unit [280], at least one temperature sensor [300] and a control unit [310].
The water tank C [120] act as a secondary tank for storing over flown water from the water tank A [140]. The water tank C [120] may also be used to fill the water tank A [140] in an event of shortage of water in the water tank A [140]. Further, the water tank C [120] may also be used for storing rain water. The water tank C [120] may be connected to the water tank A [140] by the conventional connecting means such a pipes. The water tank C [120] may use a first pump unit to supply water to the water tank A [140]. The first pump unit may be a conventional pump unit known in the art.
The water tank A [140] is the primary water tank for storing the water. The water tank A [140] is configured to sprinkle water on the solar panel [160]. The water tank A [140] may be kept either at a normal ambient temperature or at a temperature lower than the ambient temperature. In an event of the

temperature is lesser than the ambient temperature, the water tank [140] may be buried under the ground. The water tank A [140] may use a second pump unit to supply the water to the at least one sprinkler [150]. The second pump unit may be a conventional pump unit known in the art.
The at least one sprinkler [150] is configured to sprinkle the water received from the water tank A [140]. The at least one sprinkler [150] breaks the water drops into smaller droplets, and distributes the water droplets over the solar panel [160]. The distributed pressurized fluid creates an impact force on the surface of the solar panel [160] and thus, cleans and cools the surface of the solar panel [160]. The at least one sprinkler [150] may include, but not limited to, a plain orifice spray nozzle, a spiral spray nozzle, a pressure swirl spray nozzle, or any spray nozzle as may be obvious to a skilled person. The spiral design generally produces a small fluid droplet size and is clog resistant due to the large free passage. In an embodiment, the at least one sprinkler [150] may be a spiral spray nozzle with full cone spray pattern. Further, the at least one sprinkler [150] may be adjusted to spray at different angles. The nozzles may be placed equidistance to each other to achieve uniform supply of sprinkled water on the top surface of the solar panel [160]. The sprinkled water may roll downwards under the influence of gravity. On rolling the water, the heat accumulated inside the solar panel [160] may get transferred to the sprinkled water.
The solar panel [160] may be installed inclined to the ground. The solar panel [160] may include a single solar panel or an array of solar panels. Further, the at least temperature sensor [300] may be configured on a top surface of the solar panel [160]. The at least one temperature sensor [300] is configured to sense the temperature data of the surface of the solar panel [160]. The at least one temperature sensor [300] may be sense the temperature data at every instant or at period interval. The at least one temperature sensor [300] may transmit the temperature data at every instant or periodically to the control unit [310]. The at

least one temperature sensor [310] may a conventionally known temperature sensor.
The control unit [310] may be a processor or a microprocessor. The control unit [310] may also configure to store the temperature data received from the at least one temperature sensor [300]. The control unit [310] may comprise a storage unit to store the temperature data. The control unit [310] may be configured to compare the temperature data with a pre-determined temperature data. The pre-determined temperature data may be stored by a user in the storage unit. The pre-determined temperature data denotes the optimum working temperature data of the solar panel [160]. The control unit [310] may also be configured to control to power supply to the second pump unit in order to control the water supply from water tank A [140] to the at least one sprinkler. In an event, the temperature data exceeds the pre-determined temperature data, the control unit [310] activates the second pump unit so that the water from the water tank A [140] may be supplied to the at least one sprinkler. The at least one sprinkler further sprinkles the water on the surface of the solar panel (as described above).
In another event, the temperature data falls below the pre-determined temperature data, the control unit [310] de-activates the second pump unit so that the supply of the water from the water tank A [140] to the at least one sprinkler may be stopped.
As described above, the sprinkled cold water absorbs the heat accumulated inside the solar panel and gets collected in the trough collector [180]. The trough collector [180] may be configured to collect the sprinkled water. The collected sprinkled water may be termed as hot water as the collected sprinkled water gets heated to due to absorption of heat from the solar panel [160]. The hot water is passed through the filter [200] to to remove any sand or dirt and is finally stored in the water tank B [220].

The water tank B [220] is also a tank configured to receive the hot water from the filter [200]. The water tank B [220] is also configured to store the hot water. The water tank B [220] may also utilize a third pump unit to supply the hot water to the heater exchanger [240]. The heat exchanger [240] may be a conventionally known heat exchanger. The heat exchanger [240] may include, but not limited to, a shell and tube exchanger, a plate heat exchanger and phase change heat exchanger. Further, the heat exchanger [240] comprises a first conduit [240A] and a second conduit [240B]. The first conduit [240A] and the second conduit [240B] shares a permanent physical touch (conductive wall) between each other for transferring heat. The hot water is configured to flow through the first conduit [240A], whereas a first fluid is configured to flow through the second conduit [240B]. The first fluid is a fluid with a boiling point considerably lower than the water. The first fluid may include, but not limited to, ammonia and R-143a. Further, due to the physical touch in between the first conduit [240A] and the second conduit [240B], a heat of heated water gets transferred into the first fluid. Furthermore, the first fluid converts into a gaseous form due to the lower boiling point. However, the heated water gets cooled due to loss of heat to the first fluid and is supplied back to the water tank A [140] for reutilization. The gaseous first fluid is further expanded and is made to strike against the turbine [260]. The turbine [260] due to the impact of the gaseous first fluid rotates and thereby produces electricity. Furthermore, the electricity is transferred to the energy storage/auxiliary consumption unit [280] for either auxiliary use such as lighting street lights, running fans of stores/control rooms, or storing the electricity for future usage. However, the gaseous first fluid gets condensed after striking the turbine [260] and is supplied back to the second conduit [240C] for reutilization as the first fluid.
Further, Fig. 2 illustrated a method [200] for generating electricity using a water collected from a solar panel [160]. The method [200] starts at step [201]. At step [202], at least one sprinkler [150] sprinkles water on the solar panel [160]. This

step leads to step [204]. At step [204], the at least one collector tray [180] collects a hot water from the solar panel [160], wherein the water absorbs the heat from the solar panel [160] to form the hot water. This step leads to [206]. At step [206], a heat exchanger [240] receives the hot water from the at least one collector tray [180]. This step leads to step [208]. At step [208], the heat exchanger [240] transfers a heat of the hot water to a first fluid flowing in the heat exchanger [240]. This step leads to step [210]. At step [210], a turbine [260] receives the first fluid in the gaseous form from the heat exchanger [240]. This step leads to step [212]. At step [212], the turbine [260] gets rotated using the first fluid in the gaseous form to generate the electricity. Finally, the method [200] ends at step [214].
Therefore, the present disclosure provides a system and method for generating electricity from water sprinkled on a solar panel for cooling purpose.
