Every photovoltaic solar panel has several main components and some optional components. Solar inverters, AC/DC disconnects, solar panels, and solar mounts are an important part of any installation.

    Solar arrays, also known as photovoltaic arrays, meet the energy needs of large residential and commercial buildings. The solar array provides DC power, which is sent to an inverter, which converts it into AC power that your home can use. Solar arrays can be installed in a variety of structures and environments. However, the roof is the most common location for residential installations.

    The size of the ideal solar array for you depends on several criteria, including your energy use, available roof area, and the amount of sunlight you live in (usually measured in peak hours of sunshine). The number of solar panels you need depends on how much electricity you use each month (amongst various factors). You'll save the most money if you work hard to cover as much power usage as possible. The number of panels you need to cover your power consumption also depends on their location in your geographic area and the physical location of the array in the design itself and the direction it faces are crucial considerations. If the roof faces east/facing west, you will need more panels to achieve the same level of production as facing due south.
