So, the maximum capacity of your photovoltaic system is 5 × 200 W = 1000 W (1 kW). That is the maximum solar power you could have from your system. However, your system, in practice, will always generate power below 1000 W because of the capacity factor. Let us assume the solar capacity factor is 20%.
It is expressed as a ratio, measuring the annual average energy production of a solar PV system relative to its theoretical maximum annual energy production. For PV systems, the rated capacity is typically aggregated either in terms of all modules’ capacities or all inverters’ capacities.
For PV systems, the rated capacity is typically aggregated either in terms of all modules’ capacities or all inverters’ capacities. The ratio between these capacities, known as the inverter loading ratio (ILR), profoundly influences the calculation of the capacity factor.
The PV module capacity and solar inverter capacity ratio are commonly referred to as capacity ratio. Reasonable capacity ratio design needs to be considered comprehensively in the light of the specific project.
The designed capacity assigned by manufacturers is also called the nameplate capacity. So, the solar capacity factor is the ratio of actual solar power generation to the nameplate capacity. The capacity factor should not be confused with efficiency. You can have a very efficient system yet having a low capacity factor.
Assume your roof has five solar panels, each rated 200 W. So, the maximum capacity of your photovoltaic system is 5 × 200 W = 1000 W (1 kW). That is the maximum solar power you could have from your system. However, your system, in practice, will always generate power below 1000 W because of the capacity factor.
