“…Regardless of the effect FITs are having on renewable energy adoption, the society in general is on the brink of a huge energy transformation in terms of supply and demand. The fact that efficiency of small scale PV's and solar concentrators are on the rise [29] and not to neglect the effect battery storage will have on the renewable use. In the near future it is expected that the battery storage cost will be reducing nearing the cost of grid supplied energy [30].…”

Australia has been striving hard to meet the Renewable energy Target (RET). Every state in Australia has been contributing to meet RET. The Australian government has introduced energy policies to aid the adaption of renewable energy, including feed in tariffs (FiTs). The impact of FiTs in the renewable energy economics for an Australian scenario has been analyzed in this study. A university set up has been considered and the economics for optimally sized renewable energy resources is examined. In this paper the economic impact for the consumers on adapting grid connected renewable energy sources and the effect of FiTs has been analysed for the university building. The advantages and disadvantages have been scrutinized and suggestions for further improvements in FiTs for Australian scenario has been suggested.

“…Cavity receivers containing liquid-metal reflux components are ideal options for dish systems due to several advantages, such as blackbody effect, high thermal transfer ratio, and isothermal heat source for the engine (Moreno et al, 1991). A range of designs and thermal models for cavity receivers in dish systems have been developed using numerical and/or experimental methods (Adkins et al, 1995;Andraka et al, 1994;Bader et al, 2015;Daabo et al, 2016;Loni et al, 2018;Loni et al, 2017;Moreno et al, 1991;Paitoonsurikarn and Lovegrove, 2006a, b;Pavlovic et al, 2017;Pye et al, 2016;Reddy and Kumar, 2009;Reddy and Nataraj, 2018;Shuai et al, 2008;Taumoefolau et al, 2004;Wu et al, 2011;Zou et al, 2017). In early 1990s, the Sandia National Laboratory (SNL) (Moreno et al, 1991) demonstrated a 75-kW sodium heat pipe receiver in Sandia's nominal 75-kW parabolic-dish concentrator.…”

“…Other studies have presented improved receiver configurations for solar dish systems, e.g. based on heat pipes (Wu et al, 2011) and receivers with special cavity geometries (Pye et al, 2016;Shuai et al, 2008). Also different design and optimization methods for solar cavity receivers (Zou et al, 2017) and performance analyses for different working fluid (Loni et al, 2018;Pavlovic et al, 2017) have been presented.…”

Design and performance evaluation of a high-temperature cavity receiver for a 2-stage dish concentrator

Here a new design of a cavity heat-pipe receiver for a 2-stage dish concentrator is proposed. Both optical and thermal simulations are used for the design and for performance evaluation of the cavity. The receiver was fitted to a conventional 2-stage and an improved (overlapped) 2-stage dish. The latter system configuration shows superior performance compared to the conventional one, in particular in terms of compact structure, uniformity of the incident flux and temperature distribution, and solar-to-thermal efficiency. The variance of the irradiation distribution at the cavity decreased by 25% and the largest adjacent temperature difference decreased by 54%. In total, the conversion efficiency increased from 61.3% to 68.6%. Moreover, the new receiver with the improved 2-stage dish concentrating system has less limits of scales (e.g. weight and volume) compared to the traditional single dish design.
