“…The CPV power system [10][11][12][13][14][15] improves a solar cell's power-generation efficiency by concentrating and illuminating solar energy onto a relatively small area of the solar cell by using an optical system such as refractive or reflective optics. The great advantage of a CPV power system is that it offers a cost-effective alternative to a conventional flat-plate photovoltaic system by reducing the number of expensive solar cells.…”

“…The HCPV modules proposed by Jaus et al [12] used a Fresnel lens array as the primary concentrator to enhance the overall system performance, and a secondary reflective mirror optic was installed at the focal point of the CPV system to ensure uniform illumination of the solar cells and to secure a wider acceptance angle of the CPV module. Low-concentrating photovoltaic (LCPV) systems [13][14][15] are less complex than HCPV systems and are widely used in ground-based applications due to their higher tracking tolerances, passive heat sinks, lower manufacturing costs, and reduced installation precision. Butler et al [15] developed a nontracking LCPV system, which significantly reduces costs by minimizing the cell contribution and which also has a larger acceptance angle for solar tracking tolerance than the HCPV system.…”

The reflectors consist of two faces on either side of a trough, which is aligned to attain the desired concentration ratio of 3 suns, and then single or multiple connected solar cells in the receiver plane are illuminated to increase the module's power output.…”

The ability to produce sufficient power is an important factor in assuring the success of the challenging and complex cube satellite (CubeSat) missions within an extremely small size. A CubeSat has only a limited surface area on which solar panels can be installed to generate power. The incidence angle of sunlight on the solar panels also varies according to the revolution and rotation of the satellite. These are important parameters for determining the amount of power that a CubeSat can generate. In this study, we propose a concentrating photovoltaic system for CubeSats that enhances the efficiency of power generation by effectively concentrating the solar energy on the solar panels by using a multi-array lens system under the worst condition for sun incidence angle. The feasibility of using the concentrating photovoltaic system for CubeSat applications is demonstrated by power measurement tests using a solar simulator and a commercial multi-array lens under various light source angles.

“…The PV modules used in the CPV plants are typically the same as the ones used in traditional PV systems and they have been modelled using an equivalent circuit with a (photovoltaic) current generator, connected in series with a resistance and in parallel with a diode and another resistance. This opto-electronic model of each PV cell has been taken from De Soto et al (2006), whilst the modelling part concerning with the concentrating mirrors in the CPV case has been taken from Butler et al (2012).…”

a b s t r a c t a r t i c l e i n f o Available online xxxxWe present innovative web tools, developed also in the frame of the FP7 ENDORSE (ENergy DOwnstReam SErvices) project, for the performance analysis and the support in planning of solar energy plants (PV, CSP, CPV). These services are based on the combination between the detailed physical model of each part of the plants and the near real-time satellite remote sensing of incident solar irradiance. Starting from the solar Global Horizontal Irradiance (GHI) data provided by the Monitoring Atmospheric Composition and Climate (GMES-MACC) Core Service and based on the elaboration of Meteosat Second Generation (MSG) satellite optical imagery, the Global Tilted Irradiance (GTI) or the Beam Normal Irradiance (BNI) incident on plant's solar PV panels (or solar receivers for CSP or CPV) is calculated. Combining these parameters with the model of the solar power plant, using also air temperature values, we can assess in near-real-time the daily evolution of the alternate current (AC) power produced by the plant. We are therefore able to compare this satellitebased AC power yield with the actually measured one and, consequently, to readily detect any possible malfunctions and to evaluate the performances of the plant (so-called "Controller" service). Besides, the same method can be applied to satellite-based averaged environmental data (solar irradiance and air temperature) in order to provide a Return on Investment analysis in support to the planning of new solar energy plants (socalled "Planner" service). This method has been successfully applied to three test solar plants (in North, Centre and South Italy respectively) and it has been validated by comparing satellite-based and in-situ measured hourly AC power data for several months in 2013 and 2014. The results show a good accuracy: the overall Normalized Bias (NB) is −0.41%, the overall Normalized Mean Absolute Error (NMAE) is 4.90%, the Normalized Root Mean Square Error (NRMSE) is 7.66% and the overall Correlation Coefficient (CC) is 0.9538. The maximum value of the Normalized Absolute Error (NAE) is about 30% and occurs for time periods with highly variable meteorological conditions.

“…Solar concentrators are finding increasing applications in: Photovoltaic power generation [1][2][3][4]; Steam turbine power generation [5][6][7] and energy storage systems [8]. There is also possibility of future applications of solar concentrators in thermionic power generation, the latter being much easier, simpler than power generation through other means such as steam turbine, photovoltaic systems etc.…”

For efficient and cost effective utilization Solar energy solar concentrators are vital. These are finding increasing applications in many solar energy applications such as concentrated solar photovoltaics, solar steam power generation, solar energy storage, solar cooking etc.. In this brief review we discuss the various types of solar concentrators, their current applications, advantages and disadvantages. We also suggest future new applications of solar concentrators.
