The proposed study aims to optimize a combination of solar irradiation and biogas with the organic Rankine cycle which offers a hybrid system that uses two renewable energy sources. Experience often dictates how these organic Rankine cycles should be configured, but experience does not always result in the most optimal configuration. This optimization involves combining the configurations of components and cycle parameters, which are the temperatures, pressures and mass flow rates to achieve the most efficient system. In this review paper, a comprehensive overview of solar organic Rankine cycle technology and the range of systems that have been studied in the literature has been provided. The best working fluid to be used is R134a and R245fa in the hybrid driven organic Rankine cycle. A flat plate solar collector was found to be sufficient for producing low kilowatt power generation. Plate heat exchangers were selected since they are suitable for low heat recovery, they are readily available and cost-effective. A scroll compressor used from the refrigeration industry converted into an expander will be used to generate power. To ensure maximum thermal energy storage, a sensible heat storage approach will be taken. Additionally, limitations of this technology are discussed, along with suggestions aimed at guiding future research in this area.
