The following specification particularly describes the invention and the manner in

FIELD OF THE DISCLOSURE
The present disclosure generally relates to systems and methods used for generating solar power.
Particularly, the present disclosure relates to a solar dish.
BACKGROUND OF THE INVENTION
Solar power is the power obtained by the conversion of sunlight into electricity or any other form of energy. Sunlight is directly converted into electricity by means of photovoltaic method. Alternatively, the sunlight is indirectly converted into electricity by means of solar dish systems. Generally, solar dish systems are made up of several components such as a top ring, a bottom ring and connecting elements. The top ring is connected to the bottom ring by means of the connecting elements. Typically, each of the top ring, the bottom ring and the connecting elements is made of a single piece structure. These single piece top ring, bottom ring and connecting elements are bent in required shape with the help of a bending machine for formation of a solar dish system. However, such bending process is cumbersome and involves skilled manpower.
The conventional solar dish systems include locking and tracking arrangement that are ineffective in locking and tracking of a solar dish during high wind and normal operation. Wind is one of the critical factors which disturb the position of a solar dish if the locking is not proper. Since the components of the conventional solar dish systems need to be welded and painted at the site, on site welding of components are not effective since there is no proper cleaning of

the rusted surface that needs to be welded leading to fast paint peel off and decrease in the life of a solar dish system.
Moreover, the components of the conventional solar dish systems are susceptible to get damaged and the shapes of the dish components may get distorted due to improper packing of the components. The damages in components shape leads to imperfect parabolic shape of dish, since the parabolic shape is not maintained, the rays reflects to some other portion than a receiver which affects the performance of a solar dish system.
Further, the reflector fixing arrangement of the conventional solar dish systems is made up of aluminum sheet which is fixed to a solar dish and has to face the wind which reduces the life of the conventional solar dish systems. Also, the conventional solar systems suffer from disturbance in the focus due to which rays are not reflected at the centre, which increases cooking or heating time. Further, the conventional solar dish systems require high transportation cost, since the conventional solar dish systems require transportation of complete system to the site.
Accordingly, there is need of a solar dish that is easy to assemble. Also, there is. need of a solar dish that is easy to transport. Additionally, there is need of a solar dish that is effective in tracking and locking a solar dish. Furthermore, there is need of a solar dish that has comparatively more life. Moreover, there is a need of a solar dish that has perfect parabolic shape of dish.

Also, an object of the present invention is to provide a solar dish that has perfect parabolic shape of dish.
