Development of a Fresnel lens based high-flux solar simulator

Design and Construction of a Sun Simulator for Laboratory Testing of Solar Cells

“…The result is a light intensity distribution formed by a single halogen lamp at a given position, from which the future light intensity distribution will be determined. Figure 2 illustrates the light intensity distribution obtained by LED and halogen light sources [17][18][19]. After the superposition of light intensity distributions produced by the LED and halogen lamps, the next step is to find the variables, with which the inhomogeneity of the light distribution is at nadir.…”

“…Power supply can be divided into two groups, since the power supply of the halogen lamps and the LED units must both be insured. Powering the halogen lamps is rather simple, since the 8 halogen lamps (with GU10 socket) are powered from the electrical grid through two dimmer switches [12,[17][18][19]. The halogen lamps can further be divided into two groups according to their dimming; these groups are halogen lamps on the sides and in the corners.…”

“…It is not liable to warping or deformation, and besides can be used to construct a relatively slim structure. Halogen bulbs are held by threaded stems attached to the grooves of radially placed grooved flat iron rods [17][18][19]. The heatsink hangs from four threaded iron balls.…”

A simple solar simulator with highly stable controlled irradiance for solar panel characterization

“…[2][3][4][5] Another group of solar simulators with highflux concentrators are operated in producing high temperatures for research in materials processing, thermochemical reactions, solar fuels production, and simulated solar thermal power generation. [6][7][8][9][10] Solar cells along with batteries and power managements were used to supply electrical power for various monitoring systems, such as natural disaster monitoring systems, [11][12][13][14][15] structure health monitoring, 16 aquaculture monitoring, 17 and underground mining area monitoring, 18 which is placed in remote or inaccessible areas. Tests of solar cells along with their batteries and power managements using a non-concentrating uniformly distributed solar simulator are therefore very important to make sure the continuous power supply to the monitoring systems.…”

Scaling effects of a novel solar receiver for a micro gas-turbine based solar dish system

“…The development process of solar receivers for CSP plants often involves the testing of a scaled version in a laboratory environment with controllable testing conditions and reduced system complexity as compared to the full-scale system. In recent years, high-flux solar simulators (HFSSs) have gained importance for the development of CSP components and systems as they offer a fully controllable and constantly available testing environment at lower costs than using a fullscale solar platform [23] [24]. A recent review of solar simulators [25] showed that 26 HFSSs of various designs were in operation in late 2016 with 7 of them capable of providing a radiative power of more than 15 kW and 3 capable of providing more than 30 kW at the focal plane.…”
