“…Malaysia offers an abundant potential for the use of renewable energy resources, especially solar and wind power. There has been a lot of new policy, funds, investment and programs being implemented by the government although the development of renewable energy sources is still limited and not fully utilized [6]. Malaysia is gifted with a natural tropical climate with average daily solar radiation of 4.5 kWh/m 2 /day (2011) and abundant sunshine [7] for about 12h/day.…”

Solar air collector is a device that collects heat energy from the sun where solar energy is converted to heat energy. A good solar air collector is when it can absorb maximum heat and can reduce as minimum as heat loss possible. In this study, a solar air collector device has been designed and constructed by attaching an aluminium rod of 210 pieces with height 2 cm on the absorber plate to increase the heat transfer surface area. Apart from that, fin also built in the airway to increase the transfer of heat from plate absorber to air flow. There are 4 parameter of intensities value and mass flow rate is changed in this experiment which are 101.5 W/m 2 , 302.4 W/m 2 , 530.6 W/m 2 and 720.0 W/m 2 while for the mass flow rate is 0.0236 kg/s, 0.0340 kg/s, 0.0452 kg/s and 0.0584 kg/s. The aim of this study was to investigate the effect of mass flow rate and the solar intensity in improving the efficiency of thermal solar collectors. The results showed that the efficiency is between 57.2% to 77.4%. Maximum thermal efficiency mass flow rate recorded at 0.0584 kg/s with solar radiation intensity of 530.6 W/m 2 .

This paper elaborates a comprehensive overview of a photovoltaic (PV) system model, and compares the attributes of various conventional and improved incremental conductance algorithms, perturbation and observation techniques, and other maximum power point tracking (MPPT) algorithms in normal and partial shading conditions. Performance evaluation techniques are discussed on the basis of the dynamic parameters of the PV system. Following a discussion of the MPPT algorithms in each category, a table is drawn to summarize their key specifications. In the performance evaluation section, the appropriate PV module technologies, atmospheric effects on PV panels, design complexity, and number of sensors and internal parameters of the PV system are outlined. In the last phase, a comparative table presents performance-evaluating parameters of MPPT design criterion. This paper is organized in such a way that future researchers and engineers can select an appropriate MPPT scheme without complication.

“…Even though solar energy from the sun is the largest freely available renewable energy that will never run out, harnessing this solar power is a great challenge. Currently, a solar module system's power output efficiency of only about 15-30% (Azman et al, 2011;Akorede, 2012;Mekhilef, 2012;Rajendran et al, 2014;Smith and Rajendran, 2014;Wilson and Mooney, 2013). Therefore, this situation makes the current system unattractive to be widely used for powering an unmanned aerial vehicle (UAV).…”

“…Undoubtedly, the main causes of poor performance in these solar modules are the lack of consideration of the atmospheric conditions and geological locations (Azman et al, 2011;Engel-Cox et al, 2012;Akorede, 2012;Gaafar, 2012;Masral et al 2015;Mekhilef, 2012;Rajendran and Smith, 2015). Solar UAV designers rely on general solar irradiance data to design the UAV's solar module system that averages the solar irradiance value of a particular city and the daylight duration for a particular month of a year (SoDa, 2014).…”

Solar energy from the sun is the largest available renewable energy that enhances the endurance of a solar powered unmanned aerial vehicle. However, harnessing this solar power is a great challenge. This is due to having solar module system's power output efficiency of only about 15-30%. However, a solar powered unmanned aerial vehicle has the potential to outperform a battery only operated unmanned aerial vehicle, especially when task being a pseudo satellite which requires long operating hours. The atmospheric conditions and geological locations undoubtedly the main cause for poor performance of these solar modules. In spite of its prolific improvement in solar cell efficiency over the years, the overall solar module system barely converts half of sun's power into electricity. Therefore, this situation makes the current system unattractive to be widely used for energy harvesting. Recent attention has been focused not only on type of solar cells but on its positioning system. However, there were lack of understanding and research on the solar irradiance intensity and daylight duration's effect on the power output. Therefore, a comprehensive model was developed to study on how the sun movement affects the solar module system's performance. This simulation model has identified the daylight duration is more important in comparison to the available solar irradiance. Moreover, the higher the solar irradiance and daylight duration, the solar module system gives the most power output. The daylight duration also depends on the latitude where the higher the latitude gets, the longer the daylight duration. Besides, the longitudinal coordinates and elevation have minor effect on the daylight duration estimation. In other words, in summer, the northern hemisphere has more advantage compared to the southern hemisphere locations and vice versa.
