Solar PV systems that are connected to the grid operate by transforming the electricity generated by the solar system
(which is direct current (DC)) into alternating current (AC) electricity using an inverter, so that the power generated is
compatible with the grid and ordinary business needs. Businesses with solar PV systems use solar power fi rst before sourcing electricity from the grid. When the panels are not producing enough power to meet load requirements the balance is drawn from the grid. This would be the case at night or on an overcast day.
