What are the major system components of a solar system?

A typical PV system is made up of several key components, including:
PV modules:
Module technologies are differentiated by the type of PV material used, resulting in a range of conversion efficiencies from light energy to electrical energy. Two common PV technologies that have been widely used for commercial- and utility-scale projects are crystalline silicon and thin film.
Inverter:
Inverters convert DC electricity from the PV array into AC and can connect seamlessly to the electricity grid. Inverters also sense the utility power frequency and synchronize the PV-produced power to that frequency.
Balance-of-system components:
Mounting racks and hardware for the panels. Typical mounting systems can be categorized as fixed tilt or tracking. The selection of mounting type is dependent on many factors, including installation size, electricity rates, government incentives, land constraints, latitude, and local weather.
Wiring for electrical connections:
Electrical connections, including wiring, disconnect switches, fuses, and breakers are required to meet electrical code for both safety and equipment protection.
