The main components of a photovoltaic system include cells, panels or modules, arrays, a battery, a charge controller, a voltage regulator, a low voltage disconnect, an inverter, loads, a meter, a generator, and an overcurrent protection which includes fuses, circuit breakers, disconnects and grounding.
To design a photovoltaic (PV) system, first divide your energy use by the available solar insolation to get your number of maximum installed Watts. Then, design a PV system that meets your electrical power needs given the parameters of the available insolation (Keep in mind that solar insolation varies seasonally and daily). This process includes sizing an array, sizing batteries, and specifying a controller.
To calculate the maximum installed watts of a photovoltaic system, you need to determine the solar insolation in your region and location of the PV panel. This is done with your latitude or distance from the equator. Divide your energy use by the available solar insolation to get your number of maximum installed Watts.
