FIG. 1
The present invention relates to a system for cleaning. In particular, the present invention relates to a system for cleaning solar panels.
Need for energy is ever increasing. At present the sources of energy include non-renewable sources such as coal, oil, natural gas, etc., and renewable sources such as wind, solar energy, sea waves/tides, etc., are being employed to cater the ever-increasing energy needs. Non-renewable energy sources are limited, and some day or the other these would be exhausted.
Therefore, attempts are being made to develop or improve the systems and methods to harness the renewable energy sources.
One such renewable energy source is solar energy. The solar energy in form of sunlight is captured by employing solar panels or photo-voltaic modules. The solar panels employ sunlight energy (photons) received from the Sun to generate electricity. The solar panels include wafer-based crystalline silicon cells which absorb or capture the photons, and are converted into electricity.
Typically, the solar panels include a plurality of solar cells. The solar panels are operatively disposed on supporting structures which enable the solar panels to be titled. The solar panels may be installed on buildings, or ground. These installations may include a single solar panel or a large farm of solar panels. The solar cells may be covered with a protective layer(s) to protect them from water, dust, or dirt. Any collection of dust or dirt or debris may result in significant under performance of the solar panels, which may result in reduced electricity generation, or permanent damage to the solar panels.
Attempts have been made to develop systems and methods focusing on cleaning of the solar panels in the solar panel farms. The conventional systems include apparatus or devices which operate manually or semi automatically or a combination thereof.
However, there are certain drawbacks associated with the conventional cleaning systems and methods.
One drawback is that the conventional cleaning systems are exorbitantly expensive not only for building, and installation, but for operating and maintaining.
Another drawback is that the conventional cleaning systems are not effective and efficient in cleaning the solar panels in large farms.
Still another drawback is that the conventional cleaning systems may damage the solar panels, which may render them useless.
Yet another drawback is that the conventional systems cannot be used for cleaning solar panels with different heights and inclinations.
Another drawback is that the conventional systems are not completely automated and need some human intervention.
Another drawback is that the conventional systems cannot be employed for cleaning solar panels, wherein the solar panels are spaced apart from each other or disposed at a distance from each other. The existing conventional cleaning systems are disposed on the solar panel and cannot be employed to clean another solar panel.
Therefore, there is felt an urgent need to provide an automated solar panel cleaning system that overcomes one or more drawbacks associated with the conventional cleaning systems
Some of the objects of the presently disclosed invention, of which at the minimum one object is fulfilled by at least one embodiment disclosed herein are as follow:
An object of the present invention is to provide an alternative, which overcomes at least one drawback encountered in the existing prior art;
Another object of the present invention is to provide a solar panel cleaning system.
Still another object of the present invention is to provide a solar panel cleaning system which is relatively inexpensive for building, installation, operating and maintaining.
Yet another object of the present invention is to provide a solar panel cleaning system which is effective and efficient in cleaning the solar panels in large farms.
Another object of the present invention is to provide a solar panel cleaning system which reduces or eliminates any damage the solar panels during the cleaning process.
Another object of the present invention is to provide a solar panel cleaning system which can be used for cleaning solar panels with different heights and inclinations.
Another object of the present invention is to provide a solar panel cleaning system which is completely automated and need no human intervention.
Another object of the present invention is to provide a solar panel cleaning system which can be employed for cleaning solar panels, wherein the solar panels are spaced apart from each other or disposed at a distance from each other.

The hollow column (402a) can be made of any material including metal, metal alloy, non-metal, and any combinations thereof. The hollow column (402a) may have a cross sectional shape selected from the group consisting of circular, rectangular, square, trapezoidal, and any combinations thereof. The hollow column (402a) can be secured to the flat plate (304) by employing suitable fasteners or can be directly welded thereto. In one embodiment of the present invention, the hollow column (402a) is integrally configured on the flat plate (304). In accordance with one embodiment of the present invention, the hollow column (402a) is made of L-shaped plates (as shown in FIG. 5A).
In accordance with one embodiment of the present invention, an inflatable fluid bag (402b) is operatively received within the hollow column (402a). The inflatable fluid bag (402b) is configured to receive and dispense a fluid, from a source of fluid, thereby facilitating flattening and inflating of the inflatable fluid bag (402b). The fluid may be pumped in or out of the inflatable fluid bag (402b) using a suitable pump. In one embodiment, the inflatable fluid bag (402b) is configured to get inflated in an operative upward direction.
Further, a first arm (402c) extends in an operative upward direction from a plate (402p) disposed on the inflatable fluid bag (402b). The plate (402p) is operably connected to an upper free end of the inflatable fluid bag (402b). The inflatable fluid bag (402b) is configured to expand or inflated in the operative upward direction within the hollow column (402a) such that the plate (402p) and the first arm (402c) is lifted in an operative upward direction, whereas when the fluid is drawn out of the inflatable fluid bag (402b) the plate (402p) and first arm (402c) are displaced in an operative downward direction within the hollow column (402a).
In accordance with one embodiment of the present invention, the first arm (402c) is supported and guided by guiding elements (402cg) which support and guide the first arm (402c) when inflatable fluid bag (402b) is being inflated or flattened by pumping the fluid to and from the inflatable fluid bag (402b). The guiding elements (402cg) ensures that the first arm (402c) moves or is displaced in an operative straight line and sidewise deflection or movement of the first arm (402c) is prevented or avoided.
In an embodiment the first arm (402c) has a plurality of through holes (402c1) configured thereon.
In accordance with one embodiment of the present invention, instead of the inflatable fluid bag (402b), any other mechanism may be employed to lift up or displace the first arm (402c) up or down. For example, the mechanism may employ a piston and cylinder.
In accordance with one embodiment of the present invention, the support and articulation system (402) further include a second arm (402d). The second arm (402d) is provided with a through hole (402dhl) at a first end thereof and a plurality of through holes (402dh2) configured at a second end thereof. The second arm (402d) is displaceably and rotatably coupled and secured to the first arm (402c) at a predetermined angle. More specifically, the second arm (402d) is coupled to the first arm (402c) by employing a suitable fastener which is received in one of the through holes (402c1) configured on the first arm (402c), and the through hole (402dhl) of the second arm (402d). By choosing the right through hole (402c1) on the first arm (402c), the height of the second arm (402d) can be fixed. Further, a dead weight (402w) is secured to the first end of the second arm (402d), wherein the dead weight (402w) is chosen such that the weight of the cleaning mechanism (404) is balanced by the dead weight (402w).
