“…Of course, wind falling on the back side of passively cooled HCPV modules improves heat dissipation and decreases T c , which increases the module's efficiency. Another effect of wind is originating temperature differences between the solar cells in an HCPV module depending on its direction and the orientation of the module [29,30].…”

High-concentrator photovoltaic (HCPV) modules incorporate solar cells, optical devices, cooling mechanisms, and other elements in an assembly to provide the functions required to concentrate sunlight and obtain electricity. The variety of designs for configuring HCPV modules is introduced in this chapter. Thermal management, an important aspect to be considered in the design of these modules, is discussed, as are the possibilities and innovations for implementing cooling mechanisms. The behavior of HCPV modules is complex because of the different interdependent elements and involved processes and because of the changing operating conditions in the field. The experimental analysis of available modules has motivated progress in understanding this complex behavior. The influence of different atmospheric parameters on such behavior is analyzed in this chapter. In addition, existing models for the electrical characterization of HCPV modules are reviewed. Many of these models have been recently developed and are intended for a more accurate simulation of the behavior, for easier implementation, or for meeting specific needs of the HCPV industry. The availability of reliable models to predict the energy harvested by HCPV is important to promote this photovoltaic technology.

International standard must be fair among nations. Fairness means fair among manufactures, testers and users. Present typical approaches, based on linear approximation and sampling only "good climate", may be improved by assuring fairness among spectrum and irradiance conditions among nations. In unwanted area, low efficiency days are usually humid and white-sky days. The energy anticipation will be underestimated based on the measurement by manufacturers in unwanted countries. This is not fair among manufactures. If we only filter "good climate data", it may be helpful to users in good irradiance area. This filtering may be blind to the realistic conditions. This is not fair to users. The robust approach will be parabolic representation of "daily energy" based on more than 10 days data.

“…At the end of 2012, the total installed capacity was equal to 86 MW, with extra 60 MW expected to be installed by 2013 [1]. To date, numerous companies have started a CPV business, facing one of the biggest problem of this technology: the lack of agreed international standards in the CPV power rating and characterization [2]- [4]. In fact, the absence of CPV standardization let manufacturers free to use the test conditions they prefer for rating the nominal power of their CPV modules, making difficult the performance comparison [3].…”

“…Despite of this, the IEC 62108 does not impose minimum requirements for these testing devices. Additionally, international standards for rating performances of CPV trackers and simulators do not yet exist [2], [11], making more complex the standardized evaluation of CPV systems.…”

The continuing development and the increasing diffusion of concentrator photovoltaic (CPV) systems highlight the lack of specific international standards in the CPV power rating and characterization field. Presently, the only reference standard for CPV cells and modules is the IEC 62108, which does not impose minimum requirements for solar trackers and simulators used in the qualification process of CPV modules. Nevertheless, the overall quality of CPV tests is strictly associated to the technical specifications of these devices. The aim of this paper is to define optical and radiometric properties of solar simulators and the pointing accuracy of solar trackers, required for testing CPV devices and rating their performance. The results of experimental analyses on real CPV systems have been reported, highlighting the criticalities of indoor and outdoor CPV characterization. Finally an outdoor light soaking test, executed under MPPT conditions, has been proposed for the qualification process of high concentrating photovoltaic devices
