“…The entire design of the model is based on the principle of differential pressure-controlled system where the uneven heat of each canisters will cause the refrigerant to vaporize and flow from high pressure to low pressure canister and the imbalance in weight created by transfer of fluid, gravity causes the panel to tilt where there is more weight. The force generated by the refrigerant fluid must be greater than the inertial weight of the panel along with canisters setup in order to tilt the panel along the sun's path [9][10][11][12].…”

Solar Energy is the one of best renewable source of alternative energy. The efficiency of the solar panel can be improved more by tracking it in such way that it always faces perpendicular to the sun-rays throughout the day rather than it is kept fixed at an angle. At present, there are three methods for solar tracking, out of which refrigerant method is found to be more efficient as it is of a passive type and requires no external power source for its operation. In this project we have used R-134a [Tetrafluoroethene (CF3CH2F)] as the refrigerant medium for tracking the panel. To store the refrigerant, we have made use of two canisters and a copper conduit for connecting the canisters. The tracking system works on the principle of Differential Pressure Controlled system where high-pressure refrigerant from one canister to other flows and due to imbalance in the weight of canisters, the panel will tilt in the direction of the side where the weight is high due to gravity. Thus, our main objective is to harvest more solar energy at a much lower cost than the available trackers.

“…This means that tracking only occurs if the power increase is beneficial to the system by evaluating local generation conditions and estimating the increase in generation and the power consumption. Other works such as Kim and Cho (2019) propose efficient methods based on the total measurement of the celestial condition. Although efficient, it has a high financial cost and is not viable on a small scale.…”

This paper evaluated the economic potential of three different photovoltaic energy technologies at a selected site, Wa, in the Upper West region of Ghana. The cost of energy and net present value metrics were used to ascertain the cost-effectiveness of these technologies (fixed, single and double axis tracker systems). From the analysis, all three technologies are economically viable at the selected site, however, a sensitivity analysis shows that the fixed axis tracker is unviable at a discount rate above 2 % whiles that of the single and double axis power plants also become impracticable at a discount rate above 6 % using the financial input parameters adopted for the study. This is an indication that, even though the selected site may have the required solar radiation for the development of large-scale PV power plant, there is the need to create the necessary conducive financial environment to enable such projects to become viable. The double axis tracking system was identified as the optimum system that should be deployed at the selected site to get the best in terms of affordability of electricity to consumers and equity payback.
