solar radiation tracker for solar energy optimisation
CONCLUSION AND RECOMMENDATIONS
Conclusion
A dual axis solar radiation tracker for solar energy optimisation has been successfully designed at a bearable cost of GH¢ 124.45. The proposed dual axis sun tracking solar array system is a practicable and more efficient method of maximising the energy received from the sun’s radiation. Hardware design of the hardware was carefully done to ensure use of minimum number of components for implementation. Accurate tracking is as a result of use of stepper motors together with the PIC16F877A microcontroller. This was achieved with the aid of hardware design programming.
Recommendations
Based on the design the following are recommended:
• The design should be adopted and implemented by the power generating companies as a means of reducing the burden on the grid supply.
• Moreover, remote areas inaccessible to the national grid supply can give consideration to this design.
• Companies can also adopt the design as an alternative means of back – up power supply.
• Future work should concentrate on proactive tracking activity in times of cloudy weather conditions as these conditions can put the tracker to sleep calling for its manual reset.

Introduction
In this segment of the project work is presented the results and discussion. The results emanated from flowchart development and the corresponding hardware programming with the help of the PIC16F877A microcontroller.
Results
The results as presented centre mainly on the flowchart developed for control software, the hardware programming, and the respective software interfaces for building, running and debugging the program. Cost analysis is also given.
Flowchart for Control Software
The flowchart for the control software is as shown in Figure 4.1. The threshold value as stated in the flowchart varies from place to place since the intensity of the sun varies from one place to the other.
Hardware design Programming
The hardware design was programmed using mikroBasic for PIC based on the developed flowchart (Figure 4.1). The mikroBasic code of the program is as shown in Figure 4.2.
