It’s time to start the PV system design process seriously now that you are aware of the basics of a PV circuit. The three primary components of a PV system are the modules, the module support structure, and the DC-AC inverter(s). The procedure is broken down into a series of steps that begin with the size of your DC system and your annual AC energy requirement.
You should select a module with your purpose in mind that is a strong candidate for achieving it, fits on your roof, and is within your price range. Next, you use the module specifications (which are easily accessible online) to plan the array structure, create wiring configurations (strings), and do inverter calculation (s). The module model goes along with your decision of rooftop racking or ground-mount structure since they must be compatible. The remaining components are simple to add after the three essential ones (modules, support structure, and inverters) are in place because they are generally generic. The flowchart below illustrates the fundamental steps.
To understand PV system design properly, Studying some relevant examples is the greatest method to learn system design. The first example is a typical sloped rooftop (flush-mount) system with a string inverter (with adjustments for DC optimizers and flat roofs), which we will learn step-by-step. Whatever your plans, you should read this example because it thoroughly describes the fundamental design process. The next examples include a rooftop system with microinverters, and examples 3 and 4 include two ground-mount systems.
