One of the biggest obstacles to economic profitability of solar water heating systems is the investment cost. Retrofitting existing domestic hot water heaters when a new solar hot water system is installed can reduce both the installation and material costs. In this study, retrofitting existing water heaters for solar water heating systems in Swedish single-family houses was theoretically inves...

Solar adsorption refrigeration is promising technology especially in the developing countries and remote areas because the system can be driven by solar energy without involving electricity. Therefore, it is technologically possible and socially feasible in the areas where electricity is not enough but solar energy is rather easy to obtain. The conventional system works intermittently and produ...

Several short-lived radionuclides (SLRs) were present in the early solar system, some of which should have formed just prior to or soon after the solar system formation. Stellar nucleosynthesis has been proposed as the mechanism for production of SLRs in the solar system, but no appropriate stellar source has been found to explain the abundances of all solar system SLRs. In this study, we propo...

Many researchers have investigated how to increase the overall efficiency of solar-driven thermal systems. Several key parameters, such as collector efficiency and storage tank characteristics, may impose some constraints on the annual solar fraction (ASF) of such systems. In this paper, the behaviour of integrating the phase change material (PCM) in SDHW systems is modelled and optimized n...

Received Jan 10, 2018 Revised Mar 12, 2018 Accepted Mar 26, 2018 The use of solar photovoltaic (PV) system has grown significantly in Malaysia after Renewable Energy Act has been gazetted in 2011.The objective of this paper is to highlight the technical and economic analysis of solar PV DC system to generate enough energy for residential customer group that consumed 200 kWh per month so that th...

The previous paper presented at the 2016 FCRAR discussed the research topic of creating time simulating solar system models. This paper is an overview of the work done over the passed year in solar system model creation and the potential future work in STEM education. The use of designed tools to assist with relating abstract ideas to reality is now a possibility with the use of the modern manu...

This paper describes the implementation of Multi Agent System (MAS) for advanced distributed energy management of a solar micro-grid. We consider a grid connected solar micro-grid with two solar Photo Voltaic (PV) systems, and each system contains a local consumer, a solar PV system and a battery. First we measure the load patterns and solar power generated in the two solar units. Then we use M...
