NOVELTY - The system (100) has an originating container (110) including a first opening in a top portion for relieving pressure when a physical substance flows out of the container, and a second opening in a bottom portion for providing an outlet for the substance to a collecting container. A counterweight (120) is removably coupled to an end opposite of another end, and weight displacement of a solar energy collection device e.g. solar panel (101), causes the solar energy collection device to rotate over time as the physical substance flows from the second opening to the collecting container.    USE - Repositioning system for a solar energy collection device e.g. solar panel such as flat solar panel and concentrated photovoltaic solar panel (al claimed), in a solar industry.    ADVANTAGE - The system has an integrated unit using controlled weight displacement to rotate the solar panel to follow sun from east to west as horizontal solar tracking while providing clean water for an end user for maximizing an amount of electricity generated by an individual solar panel at all times during the day in a cost-effective manner. The integrated unit reduces a number of moving parts requiring attention on a daily basis and facilitates usability from minimal number of components and optimized solar energy collection and exploits the weight transfer occurring from another device. The system streamlines user experience by minimizing technical expertise required to assemble and maintain the system. The system rotates the solar panel passively without a use of active electricity, thus making the solar panel more intuitive for users, and uses conversion of potential energy to mechanical energy, thus allowing functioning parts of the system to be tangibly visible and comprehendible to any layperson. The system allows the end users having less educational background for repairing, replacing and maintaining the system with minimal external interference by minimizing technical complexity of the system. The system rotates the solar panel self-sufficiently when operated during entire exposure period to the sun. The system's calibrated weight displacement is reset to transfer the physical substance onto the weighted side of the solar panel without additional manual input during daylight hours at beginning of each day. The system protects the mounted rotating solar panel against opposing forces as wind loads to interfere with the operation of the system, and utilizes a dampener device or a skirt affixed to a bottom portion of the solar energy collection device for preventing wind from adversely affecting the system. The system allows consolidation of multiple smaller solar panels onto one tracker under same mount, proportionally adjusts a calibrated weight transfer to accommodate the additional load, and uses adjustable brackets that are operated manually by threaded screws to hold the solar panels of varying sizes in a place for addressing lack of standardization in a solar industry for the end users to build greater electrical capacities for the system. The system uses an appropriate pump if a material used for weight displacement is gravel type or solid type for minimizing manual labor and cutting down costs.
