    Improving photovoltaics performance by using yellow petroleum jelly as phase change material (2016)
    Oxford University Press
    Details
    Publication Date: 2016-08-26
    Description: Indonesia is blessed with solar energy. Photovoltaic (PV) experiences an internal problem of efficiency reduction due to temperature increase. The use of phase change material as a passive cooling has been conducted to address this problem. In this study, yellow petroleum jelly is used as passive cooling on photovoltaic. The jelly performs effectively in reducing the temperature of PV. Therefore, the application of yellow petroleum jelly on PV is proven to suppress PV temperature, increase the efficiency and the power of the PV.

    An innovative wind-solar hybrid street light: development and early testing of a prototype (2015)
    Oxford University Press
    Details
    Publication Date: 2015-11-07
    Description: An innovative renewable hybrid microgeneration unit has been designed to be fully embedded into a dedicated LED street lighting system. The key feature of this new concept is the arrangement of a multiple Savonius vertical axis wind turbine into the structure itself of the post. A photovoltaic panel is integrated to contribute to power generation. The energy is collected by a power conversion equipment along with a storage device which ensures the lighting also during windless nights. The main application of this project is the standalone street lighting, but also a grid connected option is feasible, making the system compatible with microgrid concepts. Different Savonius rotors have been designed and characterized by wind tunnel tests. The adopted cylindrical geometry has shown a maximum power factor of 0.21. A dedicated safety equipment has been designed to prevent turbine over-speed by automatic stop in extreme wind condition. A full-scale prototype of the generator/lighting system has been installed. The experimental data acquisition is currently in progress to analyse on site performance and to allow energy simulations.
