Recently, an important growth in the power of the photovoltaic systems connected to grid was observed. In spite of the advances in module technology, the problems in the system design increased, especially those related to the surface of the earth they occupy. In this work we propose a complete model for plant simulation with different wiring diagrams and under dynamic shading. Results obtained from the simulations show that the configuration with the lowest performance is that of only one serial-parallel group, whereas the highest efficiency corresponds to a design of groups of modules in parallel connected then in series. In general a higher efficiency is obtained diminishing the quantity of modules in series and increasing their number in parallel. The simulation model proposed allows exploring different alternatives of wiring modules and finding the most efficient configurations for photovoltaic plants of medium and high power.
