A solar PV design diagram is a visual representation of how a photovoltaic (PV) system is configured. It includes components such as solar modules, charge controllers, inverters, batteries, and other parts of the PV system. The diagram shows how these parts are connected to each other in order to generate and store energy for use in an off-grid or hybrid application. The layout also provides information about how much power will be generated from each item in the system and can help people decide what type and size of system they need.
