The solar panels comprise photovoltaic (PV) cells that harness sunlight into direct current (DC) electricity during daylight hours, and inverters convert the DC electricity produced by the panels into alternating current (AC) electricity.
Solar systems can be categorized into; off-grid and on-grid systems. Off-grid system is a stand-alone system that generated power during the day is stored in a battery bank. On-grid system is tied to grid that generated power can be used within the building and surplus pushed into the utility grid network
