2022 monthly US solar capacity factors underscore winter doldrums
The average annual US solar capacity factor tracked closely to the norm in 2022, hovering near the mid-20% mark. But with a gap of more than 20 percentage points between apex and nadir,

How to Calculate Solar Power Plant Capacity Factor
The capacity utilization factor (CUF) of a solar power plant is calculated by dividing the actual energy generated by the plant over a given time period, by the maximum possible energy that could have been generated at

Solar PV capacity factors in the US – the EIA data
Earlier I noted that the average solar PV capacity factor of approximately 18% at 1MW is also broadly comparable to the 16% estimate in my previous post, which was based dominantly on plants less than one MW in size.

What is capacity factor and how do solar and wind energy compare?
It is no wonder that with a capacity factor of about 90%, nuclear power continues to constitute the backbone of many electricity grids. Other forms of renewable energy, such as wind and hydro,

What is a solar capacity factor?
The capacity factor refers to the ratio of the actual energy output of a solar plant over a period of time compared to its maximum possible output if it had operated at full nameplate capacity for the same time period. It captures the plant’s utilization over time, accounting for variability and intermittency.
What is the capacity utilization factor (CUF) of a solar power plant?
The capacity utilization factor (CUF) is one of the most important performance parameters for a solar power plant. It indicates how much energy a solar plant is able to generate compared to its maximum rated capacity over a period of time.
What is the average capacity factor for different power sources?
According to the EIA, the average capacity factor for different power sources is as follows: a hydroelectric plant is 36-43%, a nuclear plant is 91-93%, a solar plant is 24-26%, and a wind plant is 32-35%, a coal plant is ~41-61% and a combined cycle gas plant is ~49-57%.
What is a capacity factor?
Capacity factor serves as a pivotal metric for evaluating the effectiveness and performance of energy generation plants, including solar installations. 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.
What is the average solar PV capacity factor?
Earlier I noted that the average solar PV capacity factor of approximately 18% at 1MW is also broadly comparable to the 16% estimate in my previous post, which was based dominantly on plants less than one MW in size. Figure 4 superimposes the capacity factors from the previous post on the EIA data out to 10MW.
What is the rated capacity of a solar PV system?
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.
