EXECUTIVE SUMMARY: This thesis is a research project of which the engineering design-approach tackled on developing solar power generation. This system consisted of solar-powered generator for collection of power through solar panel that is enhanced its capability to track down sunlight more accurately and to adjust the system to the intensity of the light to gather power efficiently. This research aimed to develop a more powerful and productive alternative source of energy that comes from the natural source using solar panel, equipped with microcontroller unit and rotating parts to control the movement of the panel with respect to the position of the sun in two-dimensional axis. This mat serve as energy source of remote area in our country that were not yet reached by local power grid provided that this research is more efficient that existing solar panels. The project research was suitable for macro level (provincial, regional, national, international) application and also in micro level including individuals communities. Combined maximum power point tracking charge controller and dual axis solar power generation using perturbation and observation algorithm is an improved type of solar-powered generator wherein the sun will be striking the panel perpendicularly at any time sunlight are present by means of controlling it using a Gizduino Microcontroller Unit (MCU). For the sensor, light dependent resistor (LDR) has been used that is adjusted to maximum sensitivity to only respond upon hitting by a ray of light coming from the sun and not by any sources to avoid malfunctioning of the said tracking system. And to perform these actions, wiper motors have been installed to panel in accordance to the present location of the sun. The system also has maximum power point tracker (MPPT) to adjust the system to the current parameters within the panel such as temperature, sunlight intensity, etc. that will ensure the maximum harvest of power at any time. Based on the experiment and evaluation made by the respondent on the completed project, the findings of the study were as follows: Combined Maximum Power Point Tracking Charge Controller and Dual Axis Solar Power generation using perturbation and observation algorithm was constructed, developed and completed. The system was tested for operations where different troubles were observed. Testing and revisions were made until the project got the purposeful output and attained the objective of the study. The project was accepted as revealed by the respondents. In terms of Safety and Maintenance, the output was very much accepted by the experts and end users with an average weighted mean of 4.7 being 5 as the highest. In terms of functionality the output was accepted with an average of 4.2. in terms of its usefulness, the project gathered an outstanding grade of 4.7 Combined Maximum Power Point Tracking Charge Controller and Dual Axis Solar power generator was found to have more output power compared to the fixed mounted solar panels and solar panels with dual axis system alone. Based on the results of the study, the researchers came up with the following recommendations: the system must be installed with a hemispherical glass magnifier that will convert the system into more efficient solar power generating product. This will increase the illumination absorption rate of the panel. And by this, it would also be possible for the system to gather light energy coming from the sun that is reflected by the moon during night time.
