The accuracy and applicability of existing methods of solar resource modelling and solar photovoltaic (PV) module performance are investigated in the case of a ground array installation at Edinburgh College, Midlothian Campus, the principal derived quantities consisting of slope irradiation, cell temperature, and cell efficiency. Experimental data were obtained on site through both automated and manual measurements for comparison with the calculated quantities. Results indicate that the horizontal-to-slope conversion models used are extremely accurate, with a greater than 99% degree of confidence in the calculated results. Likewise, correlations between measured and calculated cell temperature were very high at up to 94%. Estimations of the cell efficiency and hence module output were less reliable however, with only one of the models used, for one of the days studied, giving reasonable results. Efficiency values were, however, in the approximately correct range of 15-20%.

This chapter provides a review of the complete solar photovoltaic system that includes a discussion on the trends in manufacturing technology of the constituting components. The chapter then provides the reader with a detailed discussion on the steps that a designer will need to assess the performance of the PV system. The chapter finally presents four case studies of real installations and indicates lessons learned from them. Throughout those case studies material is provided on detailed measurements related to the incident solar radiation, PV cell temperature, thermal losses that occur from PV modules and their measured efficiency. Thus, it is possible to evaluate the accuracy of the modelling procedures using the latter measured data set.
