Inter-row-spacing plays a significant role in the performance and economics of photovoltaic (PV) systems. The performance and economics are expressed by the amount of the energy generated along the life time of the system and the payback time.
Usually power and efficiency of the assembled photovoltaic modules do not match those of the initial cells. The ratio of the final module efficiency (or power) and the initial cell efficiency (or power) is called cell-to-module (CTM) ratio and represents an indicator for the performance-tuning of the photovoltaic device.
Beforehand, a distinction ought to be made about the dimensions of the land on which the PV system is deployed: limited (e.g. rooftops) and unlimited land. Taking these factors into consideration, the optimal inter-row spacing may be derived from the solution of a “constraint optimization problem”, that formulates the design of a PV system.
The present study shows that masking losses exceed by far the shading losses for both isotropic and anisotropic diffuse radiation models. Consequently, this study proposes to use an acceptable level of masking losses as a criterion for the spacing between the PV rows.
Interconnecting solar cells and integrating them into a solar module comes along with different optical and electrical effects. A profound understanding of all factors which influence the module efficiency is essential to derive methods to decrease the losses or to increase the gains caused by module integration.
The module power is 287.3Wp, the efficiency 17.85% and the CTM power ratio is 95.8%. Figure 6. CTM-analysis of a half-cell module. Figure 7. Module power and gain after several optimization steps. To evaluate the effects of an increased number of busbars we replace the solar cell with a five-busbar version of the same manufacturer.
