The present subject matter described herein, relates to solar Photovoltaic (PV) plants in deserts, and in particular, to mounting of solar PV modules on sand filled containers for the solar PV plants in deserts.
BACKGROUND AND PRIOR ART:
[002] A solar PV plant has solar PV panel and mounting structure to mount the panel at desired location. A Solar PV plant is emerged from single PV cell-> solar PV modules -> solar panel -» solar panel array. Where single PV cell is a thin semiconductor wafer made of two layers generally made of highly purified silicon. The solar PV modules consist of PV cell circuits sealed in an environmentally protective laminate and are the fundamental building block of PV systems. The solar PV panels include one-or-more PV modules cells assembled as a pre-wired, field-installable unit. The solar panel array is the complete power-generating unit, consisting of any number of PV modules-and panels. [003] All the components of the solar PV plant are mounted on the mounting structure which provides necessary strength and stability to the plant. Further, the mounting structure of the solar PV plant required a strong concrete structure or base to support the complete solar PV plant.
[004] Conventional solar PV module mounting structures for deserts have several issues. One of the mounting structures is a structure with columns anchored in the ground. In this structure, it is difficult to excavate in the sandy soil on account of bore collapse issues. Further, arranging water for concrete and mixing is difficult in the deserts.
[005] In another mounting structure, solar PV modules are mounted on precast concrete slabs/sleepers. Therefore, it is difficult on account of logistics, i.e.. transportation cost of heavy sleepers.

[006] In another mounting structure, mounting structure is rammed via column posts. Ramming of column posts through does not require concrete free, but it is difficult to pull out the column posts which are buried in sand dunes after sand storm. Therefore, there is requirement of a portable, strong, and non-concrete mounting structure which can be used in the solar PV plant in deserts.
OBJECTS OF THE INVENTION:
[007] The principal objective of the present invention is to adopt surface
mounted type or penetration tree module mounting structures for the solar PV
modules.
[008] Another object of the present invention is to replace concrete mounting
structure for the solar PV plant with locally available material because, for
preparing concrete mix, lot of water is required which is difficult to arrange in a
desert.
|0091 Yet another object of the present invention is to provide a structure which
can be relocated after a sand storm / shifting sands.
[0010] Yet another object of the present invention is to provide a cost effective
mounting structure for solar PV panels in the desert conditions where
transportation is difficult and costly.

[0025] Fig. 1 isometric view of solar PV mounting structure, in accordance with an embodiment of the present subject matter. In the said embodiment, the mounting structure for the solar PV modules includes a plurality of L-angles 4, 5, 6, 7, 8, 9, 10, 11, first purlin 1, second purlin 2, and a plurality of tubs 3, 12. 13. The plurality of tubs can be N number of tubs, such as 3, 12, 13, 14,
15 N. In the present subject matter, one tub, i.e., 3 from the plurality of
tubs is explained for clarity point of view. The plurality of tubs is equi-distance from each other and arranged in series. Further, the plurality of tubs is made of sheet metal or plastic material which is non-corrosive in nature. The plurality of tubs has taper sides for convenience stacking. Where the sand filled tubs are used as dead weight to hold down the mounting structure and solar PV modules against wind uplift and overturning. Further, the plurality of tubs is rectangular in shape

and has more length as compare to breadth. The first purlin 1 is located at the upper side and the second purlin 2 is located at the lower side of the tub 3.
[0026] The first purlin 1 and the second purlin 2 are mounted substantially parallel each other in horizontal direction of the mounting structure. The tub 3 is attached to the first purlin 1 and the second purlin 2 with the help of the plurality of L-angles 4, 5, 9, 10. In the present mounting structure, two L-angles 5, 6 from the plurality of L-angles 4.. 11 are attached to the first purlin 1 in vertical downward direction and attached to the tub 3 from the plurality of tubs at upper side along length of the tub 3. Further, two vertical L-angles 9, 10 from the plurality of L-angles are mounted to the second purlin (2) in vertical downward direction and attached to the tub 3 from the plurality of tubs at the lower side along length of the tub 3. The two vertical L-angles 9, 10 are mounted on the second purlin 2 at the vertically opposite location of the two L-angles 4, 5 of the first purlin 1.
[0027] In between the two vertical 1.-angles 4,5 & 9, 10 of the first purlin 1 and the second purlin 2, a horizontal L-angle 6 supports and maintains the equal distance between the two vertical L-angle 4, 5 and similarly a horizontal L-angle 11 supports and maintains equal distance between the two vertical L-angle 9, 10. The horizontal support L-angles 6, 11 are located near the tub 3 which at lower side of the two vertical straight L-angles 4, 5, 9, 10.
[0028] The first purlin 1 is attached with the second purlin 2 with help of the plurality of L-angles 4. 5, 6, 7. 8, 9, 10, 11 and the plurality of L-anglcs are arranged to provide the present mounting structure. Where one L-angle 7 from the plurality of L-angles is fixedly mounted at upper location of the first purlin 1 is attached to opposite side L-angle 10 from the two vertical L-angles 9, 10 of the second purlin 2 near the tub 3. Further, the L-angle 7 is attached to the vertical L-anglc 5 at lower side of first purlin 1 and the second purlin 2 in downwardly inclined angle from the first purlin 1 to the second purlin 2.
[0029] Similarly, the second purlin 2 is attached with the first purlin 1 with help of the plurality of L-anglcs, wherein one L-angles 8 from the plurality of L-angles

is fixedly mounted at upper location of the second purlin 2 is attached to opposite side vertical L-angle 4 from the two vertical L-angles 4, 5 of the first purlin 1 near the tub 3. Where, the L-angle 8 is attached to the vertical L-angles 4 of first purlin 1 and the second purlin 2 in downwardly inclined angle from the second purlin 2 to the first purlin 1.
[0030] As explained above, the arrangement of the straight L-angles 7, 8 joining the first purlin 1 and the second purlin 2 is in V formation. The vertical straight L-angles joining the sand filled tubs to the module and by the V shape formation of the straight L-angles joining the first purlin and the second purlin holds the module at its location, further, the present structure prevents the sideways sway of the solar Pv module and dislocation of the mounting structure. In the mounting structure, each straight L-angles is joined with another straight L-angles and purlins with the help of rivets which are very fast and effective way of mounting. [0031] For every two solar PV modules, one sand filled tub is required. Accordingly, two solar PV modules are mounted on the mounting structure between the two sand filled tubs which are arranged equidistance in the series pattern of the present mounting structure. In one implementation, the tubs along can be made in a single pressing operation which can be mass produced and also can be transported in stacks on account of taper sides like a stack of plastic chairs or disposable thermocole tumbler in the shape of frustum of cone. [0032] Fig. 2 illustrates lop view of solar PV mounting structure, in accordance with an embodiment of the present subject matter. In this view plurality of tubs can be seen from the top side along with the purlins.
[0033] Fig. 3 illustrates front view of solar PV mounting structure, in accordance with an embodiment of the present subject matter.
[0034| Fig. 4 illustrates side view of solar PV mounting structure, in accordance with an embodiment of the present subject matter. In the view straight bars L-anglcs which are making the V shape arrangement between the purlins can be seen clearly.

[0035] In another implementation of the present subject matter, the sequence of module mounting is as follows:
> First the tubs with the legs are riveted to the first and second purlin.
> Once the tubs arc riveted, sand is filled in the riveted tubs to provide the
required dead weight.
> Riveting the V shape straight fi-angles between the parallel purlin and the
riveted legs.
> Once the mounting structure is ready, the solar PV modules are fitted on
the top of the first and second purlin and hence the solar PV module mounting is complete in a very efficient and less time.
ADVANTAGES OF THE INVENTION
|00361 The present mounting structure is concrete free, hence there is no need to
arrange water for concrete.
[0037] The material required as dead weight to be filled in the tubs is locally
available; in fact at the point of use. If required the local trenches can be made
using a mini-shovel, the removed material (sandy soil) can be filled back in the
tubs.
[0038] After a sand storm if some of the modules are buried in sand, they can be
reclaimed / salvaged by removing the overburden of sand and modules along with
their structures and holding tubs can be relocated on the newly formed
surface/terrains.
