Abstract

Solar power installations are extremely sensitive to the cost of the installation, the expected payback time, and the availability of energy generation over time. Many factors must be weighed in the design of a PV system (e.g., panels, arrays, inverters), but traditional design rules are too simplistic and do not make use of critical information. Often, oversized components are used that do not produce any advantages for the PV system. An alternative to the traditional approach is to optimize the different components of the system to obtain an overall system that minimizes installation cost, payback time, or other user defined targets.

In this tutorial, models, methods, and techniques will be presented to optimize the performance of the PV systems. Three aspects of the design process will be addressed: 1) PV plant size optimization, based on detailed models; 2) PV inverter stage optimization, based on power envelope and mini-boost stages; and 3) maximum power point tracking strategies. The discussion of each of these topics will focus on design considerations and on the trade-offs between different factors that lead to optimal solutions. The topics are discussed in relation to industry standard practices, and this is followed by the introduction of advanced techniques that yield better performance.
