Abstract: Research works on hybrid renewable energy systems for rural electrifications have been quite intensive in recent years. Traditional power systems for remote or rural areas are based on fossil fuels. After addition of renewable energy resources, solar energy applications have become popular in remote energy systems. The recent study and research works show that adding other possible renewable energy resources such as wind, hydro and biomass could make a hybrid system more cost-effective and environmentally friendly. Hence, in the present study, an overview of applied hybrid renewable energy system (HRES) for worldwide villages with special attention on Malaysia has been proposed to help present and future works for better achievement in this field. Furthermore, a proper design and analysis for one village in Malaysia based on proposed combination is provided. The results show that combination of photovoltaic-wind -battery is defined as a cost-effective HRES for villages in Malaysia. [Copyright &y& Elsevier]

Abstract: Building integrated photovoltaic (BIPV) systems is one of the most promising technologies and has recently experienced extraordinary growth. There is a huge consensus that these advancements lead to novel methods for domestic energy generation. Technical improvements, governmental supportive laws and financial aids are some of the contributors to this development. However, the proportion of solar power production as compared to conventional electricity generation methods is still negligible and needs more dedication. In this study, a large number of previous research works have been reviewed and reasons and solutions for BIPV success or failure are discussed. [Copyright &y& Elsevier]

Energy crisis is the worldwide main concern since fossil fuels are facing rapid depletion and its consumption contributes to the rise in the average global temperature. Among the challenges to be embedded lately with agricultural activities is to explore clean and renewable energy resources. Electrical energy generation via solar technology, or known also as photovoltaic (PV) technology, has been the most economical viable green resource, especially in tropical-based countries. The most notable problem revealed by conventional PV in greenhouses, however, is due to the antagonistic factor lying in both photovoltaic roofs and plants. As such, the divergence subsequently decreases the growth and productivity of the cultivated crops. The Dye Sensitized Solar Cell (DSSC) is thus of great importance to human as it possesses several attractive features. For instance, the fabrication of DSSC is cheap. It is also flexible, transparent, and sensitive to low light levels. Besides its easiness to be used in larger applications, makes DSSC an ideal candidate that could function greatly as energy buildings. This review article aims to explore the DSSC technology's potential and its effectiveness as a shading greenhouse. Further, in-depth understanding on the uniqueness and advantages of this technology is thoroughly assessed. In comparison to conventional PV, the DSSC technology especially on solar radiation manipulation through the optimum choice of photosensitizer is well described. This paper also consolidates all the materials employed for DSSC fabrication for greenhouse shading. Detailing photosensitizer and light harvesting within PAR wavelength for sustenance growth have been provided. This technology has the potential to improve farming productivity while contribute to a significant reduction of CO 2 emission. [ABSTRACT FROM AUTHOR]
