DESC:FIELD
The present disclosure relates to the field of solar photovoltaic systems. Particularly, the present disclosure relates to the field of transportable solar generators.
DEFINITIONS
The term “Transportable” used hereinafter in the complete specification refers to the feature of the solar generator of being easily transported from one location to another.
BACKGROUND
Conventional solar photovoltaic systems comprise an array of individual solar panels connected in series and/or parallel connection to generate a desired amount of electricity. Such systems are bulky in nature, and are therefore required to be essentially placed at a particular location. The transmission of electricity from the electricity generating grid to the rural locations is a cumbersome task as it requires erection of poles, and laying electric cables through a large distance. Moreover, current and voltage drop is observed as the distance between the grid and the rural locations to be connected increases.
Therefore, there is felt a need to develop a solar photovoltaic system that alleviates abovementioned drawbacks.

In another embodiment, the battery, along with the inverter, generates single phase AC output of 240 volts, and maximum 12 amperes of current at 50 Hz frequency. In an example, total weight of the battery is 800 kg. In another example, a rack (not shown in figures) of dimensions 2.6 m X 0.7 m X 0.5 m is provided. The rack securely holds the battery during transportation of the solar generator 100.
The tilting mechanism 106 is configured to support the plurality of solar panels 102. Further, the tilting mechanism 106 is configured to tilt the plurality of solar panels 102 to facilitate tracking of the sun throughout the day. The continuous tracking facilitates generation of optimum electric energy by the plurality of solar panels 102. The tilting of the plurality of solar panels 102 facilitates an optimal absorption of sunrays, thereby increasing the amount of generated electricity by the plurality of solar panels 102. In an embodiment, the tilting mechanism 106 is configured to tilt the plurality of solar panels 102 about the vertical and longitudinal axis of the plurality of solar panels 102.
In an embodiment, the tilting mechanism 106 includes a support structure 106A and a frame structure 106B. The frame structure 106B is pivotally mounted on the support structure 106A. The plurality of solar panels 102 is connected to the frame structure 106B using any type of fasteners. In an embodiment, the plurality of solar panels 102 is connected to the frame structure 106B of the tilting mechanism 106 by a screw and nut assembly.

In an operative configuration, the solar generator 100 is placed at a location where electricity is needed. The inverter of the solar generator 100 is connected to the appliance which requires an alternating current for its operation. If the appliance requires direct current for its operation, the battery is directly connected to the appliance. The tilting mechanism 106 tilts the plurality of solar panels 102 in order to continuously track the sun to generate optimum electricity. Further, the telescopic rod 108 is actuated to adjust the height of the tilting mechanism 106 if shadow is falling on any part of the plurality of solar panels 102.
