An inverter is an electrical device which accepts electrical current in the form of direct current (DC) and converts it to alternating current (AC). For solar energy systems, this means the DC current from the solar array is fed through an inverter which converts it to AC. In DC, electricity is maintained at. . What is a solar photovoltaic system and what does it typically consist of? A solar photovoltaic (PV) system, or solar PV system, is a power system designed to supply usable solar power by means of photovoltaics. They may also contain a battery, depending on the system and an electric meter, and the amount and type of panels for each system will depend on the. . While designs vary slightly by manufacturer, every panel relies on the same core parts working together. At the heart are photovoltaic (PV) cells that convert sunlight into electricity, supported by protective and structural layers that ensure it's delivered safely and reliably. Sunlight is composed of photons, or particles of solar energy.
