Solar simulators are used to test components and systems under controlled and repeatable conditions, often in locations with unsuitable insolation for outdoor testing. The growth in renewable energy generation has led to an increased need to develop, manufacture and test components and subsystems for solar thermal, photovoltaic (PV), and concentrating optics for both thermal and electrical solar applications. At the heart of any solar simulator is the light source itself. This paper reviews the light sources available for both low and high-flux solar simulators used for thermal applications. Criteria considered include a comparison of the lamp wavelength spectrum with the solar spectrum, lamp intensity, cost, stability, durability, and any hazards associated with use. Four main lamp types are discussed in detail, namely argon arc, the metal halide, tungsten halogen lamp, and xenon arc lamps.In addition to describing the characteristics of each lamp type, the popularity of usage of each type over time is also indicated. This is followed by guidelines for selecting a suitable lamp, depending on the requirements of the user and the criteria applied for selection. The appropriate international standards are also addressed and discussed. The review shows that metal halide and xenon arc lamps predominate, since both provide a good spectral match to the solar output. The xenon lamp provides a more intense and stable output, but has the disadvantages of being a high-pressure component, requiring infrared filtering, and the need of a more complex and expensive power supply. As a result, many new solar simulators prefer metal halide lamps. KeywordsSolar simulator, sunlight, solar spectrum, CSP, metal halide, tungsten lamp 1 Introduction The growing demand for energy, combined with issues of environmental pollution, climate change, and the rapid depletion of fossil fuels, have encouraged the research and development of cost effective renewable alternatives [1-3]. Solar electrical and thermal energy research groups have focused on developing novel technologies and on improving existing renewable solutions. In 2014, the global combined installed capacity of solar hot water and concentrating solar power (CSP) was 410.4 GW, representing 8% of the world's renewable energy sources [4].The transient nature of solar energy represents a critical challenge for technologies testing. Outdoor experiments are carried out in real but uncontrollable environments. For example, incident solar energy levels are highly dependent on atmospheric conditions and sky clarity over time [5]. Therefore, achieving

“…Solar simulators are mainly employed for testing components, materials and reactors for high temperature thermal and thermochemical applications such as redox cycles for solar fuels research. Several of these high power and high flux solar simulators for high temperature solar thermochemical experiments exist worldwide (Kuhn and Hunt, 1991;Jaworske et al, 1996;Hirsch et al, 2003;Guesdon et al, 2006;Petrasch et al, 2006;Codd et al, 2010;Alxneit and Dibowski, 2011;Krueger et al, 2011;Erickson, 2012;Nakakura et al, 2015;Li et al, 2014;Dimitrakis et al, 2013;Sarwar et al, 2014;Wang et al, 2014;Levêque et al, 2016; http://www.dlr.de/dlr/en/desktopdefault.aspx/tabid-10202/ 334_read-21807/#/gallery/26638/, 2017).

Thermochemical H2O and CO2 splitting redox cycles in a NiFe2O4 structured redox reactor: Design, development and experiments in a high flux solar simulator

et al. 2017

A high flux solar simulator allows the lab-scale assessment of solar reactor concepts by irradiating a target with high flux thermal energy, similarly to reactors installed in concentrated solar radiation facilities such as central towers with a heliostat field. In the current study, the design and construction of a high flux solar simulator facility for near realistic solar experiments is presented. A simple, cavity-tubular thermochemical reactor is employed for the evaluation of the redox activity of structured monolithic bodies (foams and honeycombs) consisting entirely of NiFe 2 O 4 w.r.tÁH 2 O splitting, CO 2 splitting and combined H 2 O-CO 2 splitting reactions. Experiments under realistic conditions, i.e. a solar reactor under irradiation, were conducted to assess the solar fuels production capability, which was examined at the structure level and the reactor level. The best performing structure was the NiFe 2 O 4 foam. Further multilevel research (structure, reactor as well as redox material), will improve product yield and reactor efficiency.

“…With this in mind, the Royal Institute of Technology (KTH) has designed and constructed a 84 kW el Fresnel lens based HFSS [1] that will be used amongst others for the development of solar receivers. Accurate boundary conditions are imperative in any analysis, and the development of solar receivers demands precise knowledge of the radiative input and its distribution at the focal plane of the receiver.…”
