Description

[0001] FLOATING SOLAR MODULE, OFFSHORE SOLAR POWER PLANT THEREOF, AND METHODS FOR THE SAME

[0002] The present application relates to renewable energy production. More particularly, the present application is floating solar module, offshore solar power plant thereof, and method for the same.

[0003] Floating solar plants, are solar panels mounted on an assembly that floats on a water body such as a reservoir or a lake pond, quarry lakes, irrigation canals or remediation and tailing ponds. Floating power plants have PV solar panels set up on top of water bodies like lakes, dams, or any other water body that is calm to prevent any damage to the panels.

[0004] Solar panels on the floating solar power plant are firmly fixed on buoyant structures to keep them afloat on water bodies to receive sufficient sunlight throughout the year. Electric current transfers from these panels to power plants through underwater cables.

[0005] However, installation of floating solar plants depends on various factors like environment, climate, technical potential, etc. Some of the significant challenges of setting up a floating solar plant such as mandatory use of high-quality materials to keep the PV panels afloat without causing rust and corrosion, climate change or flood can cause harsh damage to the floating PV setup, lack of skilled workforce for installing solar panels on water bodies, floating solar systems require a huge investment to install a technically sound power generating plant. This kind of solar plant typically is not applicable for domestic purposes as it requires a huge sum of money. Fluctuations in water levels, heavy storms, earthquakes, and tsunamis are also some of these potential risks. So fundamentally, due to delicate nature of the solar panel, and its rigidity creates hinderance in setting up the solar plant and further maintaining it keeping it economically viable.

[0006] Therefore, the subject application proposes a floating solar module, an offshore solar power plant thereof, and a method for constructing the same. Essential features of the invention(s) are provided by independent claims, whilst advantages features are provided by their dependent claims.

[0007] The offshore solar power plant of the present application provides ease of transportation of solar panels and its installation. This may enable a user to install and maintain the solar panels with more mobility saving time and effort.

[0008] The present application is described hereinafter by various embodiments. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiment set forth herein.

[0009] Principle behind the invention or embodiments is that a solar power plant is fragile and requires a lot of care and investment to install and manage. Due to constant motion of water, the maintenance of the solar panels in the plant is affected. Position of solar panel is also an issue, since, the waterbodies are always facing the sky vertically. Due to which the sun rays only fall on the solar panels during mid days. Also, due to the remote location of the solar panel, their cleaning becomes a big issue. Therefore, embodiments of the present invention provide a floating solar module, an offshore solar power plant thereof, and a method for constructing the same.

[0074] Figure 15 illustrates bridged floating solar module 500 showing damping matts or bridges 552 that connect neighbouring floating solar module 100, 101 , 103, 105 in accordance with an embodiment of the present invention. Figure 15 illustrates damping matts or bridges 552 that connect neighbouring floating solar module 100, 101 , 103, 105 in accordance with an embodiment of the present invention. As shown in figure 15, the damping matts or bridges 552 may be provided between the floating solar module 100, 101 , 103, 105. The damping matts or bridges 552 damping matts or bridges 552 may be used for retrieving, dismantling, or relocating the floating solar module 100, 101 , 103, 105.

[0075] Further, in accordance with an additional or alternative embodiment of the present invention, the offshore solar power plant 400 comprises damping matts or bridges 552 that connect neighbouring buoy 102 or the floating solar module 100, 101 , 103, 105 (e.g., connecting the first floating solar module 101 and the second floating solar module 101 ). The damping matts or bridges 552 may be used by, may be, but not limited to, cleaners or technicians to clean or repair the solar panels 104 on the floating solar module 100, 101 , 103, 105. Further, damping matts or bridges 552 may be used for retrieving, dismantling, or relocating the floating solar module 100, 101 ,103,105.

[0076] Figure 16 depicts an enlarged top view of damping mats or bridges 552 (can two items share the same reference numerals?) interlocking two side bars / shafts (or unit bar) 150 (specifically, the first side bar and the second side bar) according to one embodiment. The damping mats or bridges 552 may extend along the bars / shafts 150 between two elbows 556. All the damping mats or bridges 552 span across the entire floating solar plant 400.

[0077] In accordance with an embodiment, to secure the damping mats or bridges 552 in place and prevent it from sliding, fastening bonds 558 may be applied. The fastening bonds 558 such as but not limited to zip ties, wires, chains, ropes, etc. Furthermore, one or more gaps 554 exist between two neighbouring damping matts or bridges 552 but are less than 30 centimetres (cm) for providing a continuous walkway for the human staff. In Figure 16, three fastening bonds 558 are shown, applied to the middle portion 562 and two end portions 560, 564 (the first end portion 560 and the second end portion 564) of the damping mats or bridges 552.

[0078] Figure 17 presents a cross-sectional view of the damping mats or bridges 552 shown in Figure 16. As shown in figure 17, the damping mats or bridges 552 may only cover the upper portions of the side bars / shafts 150 to minimize material usage. However, in cases where the floating solar plant 400 is deployed in specific sea areas prone to strong winds or frequent storms, the damping mats or bridges 552 may cover the side bars / shafts entirely, forming a closed loop. The bars / shafts 150 have smooth surfaces that allow them to rotate freely without significant hindrance. Consequently, by rotating the bars / shafts 150 towards each other, the floating solar plant 400 can effectively withstand external shocks or storms. Once the external shocks or storms subside, the bars / shafts 150 will return to their original positions due to the force of gravity.

Figure 19 illustrates 550 multiple offshore solar power plants 405, 406, 407, 408 anchored together, in accordance with an embodiment of the present invention. As shown in figure 19, a first solar power plant 405 is connected with a second solar power plant 406, a third solar power plant 407 and a fourth solar power plant 408. The multiple offshore solar power plants 405, 406, 407, 408 may be connected using the connectors 402.

[0086] 408. Moreover, the damping matts or bridges 552 may provide mobility to the technicians, cleaners, mechanics to operate on various the floating solar module 100, 101 , 103, 105 of the offshore solar power plants 405, 406, 407, 408.

[0087] The present application offers a number of advantages. The present application fixes an offshore solar plant’s position relative to a point on the bottom of a waterway without connecting the offshore solar plants to shore. The floating solar module 100, 101 , 103, 105 are easy to transport and install. Further, with flexible shape, the offshore solar plant can be deployed in extreme weather conditions. Further, since the solar panels 104 are always facing the sun, the electricity output is maximised. Furthermore, because of a long duration of deployment, the solar panels 104 are required to be racked frequently, due to ease of installation and dismantling, the floating solar module 100, 101 , 103, 105 can easily be racked. Furthermore, due to quick lock assembly, labour requirements are low and large scale of floatation of the plant is possible. Since the plant is to be installed in water, there is no requirement of land remodelling and causing soil erosion therefore, this is good for environment. Freight costs are significantly lowered by easy and safe transportation of the solar modules.
