PV system capacity ratio and power limit. When the PV system capacity ratio is greater than 1, there will be excess power supply. The output power should be maintained when the photovoltaic array power supply is lower than the power limit level.
The optimization is similar to the one done for solar-only projects, with a minor increase in complexity to account for the state of charge of the energy storage. The inverter loading ratio determines the amount of additional energy that can be cost-effectively sold.
Load calculation in solar panels involves determining the total amount of electrical power needed to meet the energy demand of a household or facility. It requires an analysis of all appliances and devices consuming electricity, considering their wattage and the time they are used.
The literature considers the capacity ratio of photovoltaic panels, and designs the rated power of photovoltaic arrays higher than that of photovoltaic inverters, so that more power can be generated during off-peak periods. However, during the peak period, the PV output power is large, thus causing damage to the photovoltaic inverter.
Equipment that uses electricity to operate is called a load. Loads are the largest single influence on the size of a PV system. It is better to supply some loads with power from other generating means to limit the size of a PV system. For example, powering an electric range in a home with a PV system can be cost-prohibitive.
