Comparison of methods for estimating the solar cell temperature and their influence in the calculation of the electrical parameters in a HCPV module

Model for estimating the energy yield of a high concentrator photovoltaic system

“…Despite its simplicity, this equation has demonstrated a good performance in the estimation of cell temperature and in its application for estimating the electrical parameters of a HCPV module [40,41]. It is worth mention that this equation is not valid for modules based on active cooling mechanisms since additional parameters should be included in Equation (4) to take into account the heat removed from the cells [42].…”

A new procedure for estimating the cell temperature of a high concentrator photovoltaic grid connected system based on atmospheric parameters

“…(4) is obtained. This simple mathematical equation has been widely analysed and has demonstrated to be valid for finding the relationship between the main atmospheric parameters and the cell temperature of a HCPV module at open-circuit voltage [28,30,44]. However, this equation estimates the cell temperature of a HCPV module when is working at open-circuit, so does not take into account the portion of the DNI transformed into electricity when a module is connected to an inverter, as shown Fig.…”

Efficiencies and Energy Balance in High-Concentrator Photovoltaic Devices

“…The atmospheric parameters with the largest influence on the spectral irradiance and the behaviour of HCPV modules are, in order of importance, air mass (AM); aerosol optical depth (AOD), which is usually quantified at 500 or 550 nm; and precipitable water (PW). These parameters, together with radiative models such as the MODerate resolution atmospheric TRANsmission (MODTRAN) and the Model of the Atmospheric Radiative Transfer of Sunshine (SMARTS) [22], manage to analyze the spectral performance of an HCPV module and array [6,7,11,39]. The advantage offered by this method lies in the fact that it allows spectral effects to be evaluated for long-term analysis in remote places if atmospheric parameters are available.…”
