In the present study, cooling of PV module using a paraffin-based phase change material (PCM) in hot climate of Vietnam is investigated. Thermal modelling is first validated against experimental data reported in literature and then transient thermal simulations are carried out for a duration of 24 hours to assess the effect of PCM itself and PCM with internal fins.

Solar energy, light and heat radiation from the Sun, has been exploited by humans since ancient times using a variety of technology development than ever before. Solar radiation along with secondary resources of energy like wind and solar energy, water power and biomass, make the most of renewable energy available on earth. Only a tiny fraction of the available solar energy is used.

This research investigates an innovative approach to augmenting the current evaporation pond disposal approach used in Australia, and other regions around the world. The augmentation involves the incorporation of solar plate collector technology. The technology is widely used across the world to collect solar power to drive a range of commercial and domestic applications, most commonly solar hot water systems.

This thesis presents an evaluation of the mapping performance of a variety of SLAM algorithms that are freely available in the Robot Operating System (ROS), in conjunction with ranging data from various ranging sensors suitable for use onboard small UAS. To compare the quality of the generated maps, an existing metric was initially employed, however deficiencies noted in this metric led to the development of two new metrics. A discussion of both the existing and new map quality metrics, and the advantages and disadvantages of each, is presented as part of this thesis.

Grid-connected photovoltaic power systems are power systems energised by photovoltaic panels which are connected to the utility grid. Grid-connected photovoltaic power systems comprise of Photovoltaic panels, MPPT, solar inverters, power conditioning units and grid connection equipments. Unlike Stand-alone photovoltaic power systems these systems do not have batteries. When conditions are right, the grid-connected PV system supplies the excess power, beyond consumption by the connected load, to the utility grid.[1]...
