SUMMARY
When sizing a solar photovoltaic (PV) system, it is essential to consider the power factor (PF) of the load, as many suppliers provide power ratings in kilowatts (kW). The solar panels' kW rating should be matched with the load's kilovolt-amperes (kVA) rating to ensure compatibility, particularly because PV generators produce Direct Current (DC) that is converted to Alternating Current (AC) by inverters. The inverter must be capable of handling the reactive load, and the system must include an accumulator that matches the inverter's rating to effectively manage the output, which is dependent on insolation levels.
