This paper aims to provide a life cycle energy and carbon analysis of an indirect storage solar thermal collector (STC) system for use in the UK. A number of life cycle assessment (LCA) studies on STC systems have been carried out in the past (Crawford et al. Citation 2003, Ardente et al. Citation 2005a, Citation 2005b, Battisti and …
Fig. 1 illustrates the layout of SPT system with a novel power cycle. The energy transfer process from solar energy to electricity is described as follows: firstly, by tracking the sun position, the heliostats can accurately reflect the …
This paper introduces a chemical-looping configuration integrated with a concentrating solar thermal (CST) system. The CST system uses an array of mirrors to focus sunlight, and the concentrated solar flux is applied to a solar receiver to collect and convert solar energy into thermal energy. The thermal energy then drives a thermal …
Abstract In this research work, novel hybrid graphene-silver (Gr-Ag) nanomaterial has been used for first time with paraffin wax as a phase change material (PCM) to improve its thermo-physical properties. Thermal and electrical energy efficiencies of the novel synthesized nanocomposite (PCM/graphene-silver) has been investigated in …

Green Energy A solar hot water system can save you big money over its lifetime. The return on investment is near 8% per year and then pure income after 12-14 years. We call it GREEN ENERGY because it will make you money.
Solar thermal propulsion system combined with thermal energy storage is proposed to overcome thrust failure in shadow area. • The whole process from light concentrating, heat storage, to trust generation is numerically investigated and verified by ground tests. • ...
2.1 Experimental setup and procedure The experimental set-up mainly consists of an evacuated tube collector used for the desalination of seawater. The ETC tubes made of borosilicate glass act as an absorber. It is a tube-in-tube structure. Solar radiation is ...
Single crystalline Si solar cells are considered for the solar PV system and an evacuated glass tube collector is considered for the solar thermal system in this analysis. A life-cycle inventory (LCI) is developed considering all inputs and outputs to assess and compare the environmental impacts of both systems for 16 impact indicators.
The exergy inflow coming from the solar radiation falling on the collector surface is sometimes approximated by: (14) E ˙ in = Q ˙ * (1 − T o T *) where T* is the apparent sun temperature as an exergy source. Usually the value suggested by Petela [2] is adopted, i.e., T* is approximately equal to ¾ T s, where T s is the apparent black body …

1. Introduction The use of solar thermal and heat pump combisystems is widespread in the market of space heating (SH) and hot water preparation (DHW) for single family houses. Recent studies of the state of art in Europe [1], [2] have shown that the solar collector can be used either in parallel or in series with a heat pump, but the configuration …
The review includes analysis of various types of solar collectors and solar thermal system applications and processes. Solar collectors include flat-plate collectors, hybrid photovoltaic/thermal systems, parabolic trough collectors, parabolic dish collectors and other types of solar collectors not falling in one of the above categories.
In this work, heat transfer mechanisms involved in solar thermal devices, such as flat plate collector, evacuated tube collector, solar concentrating collectors, solar …
1. Introduction The flow in the solar loop of a low temperature SDHW solar system affects its output and cost. A low flow rate inside solar collectors contributes to a greater water tank stratification (Hollands and Lightstone, 1989, Cristofari et al., 2003), this improves collectoŕs thermal performance due to a lower inlet temperature (Fanney and …
Energy conservation by solar energy and energy matrices based on overall thermal and electrical performance of hybrid system are also discussed. Techno-economic feasibility of any energy source is the backbone of its success and hence economic analysis is covered.
