6 FAQs about [Solar power generation utilization hours]

How is the capacity utilization factor of a solar power plant calculated?

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 the plant’s rated capacity over that same time period. It is calculated using the following formula: Where:

How much energy does a solar plant produce a year?

In this example, the solar plant operated at a CUF of 18.3% over the year. This means it produced 18.3% of the maximum possible energy it could have produced if it operated at its full 10 MW capacity continuously over the entire year.

How much CUF does a 10 MW solar power plant generate?

For example, if a 10 MW solar power plant generates 16,000,000 kWh of electricity over a year with 8760 hours, the CUF calculation would be: In this example, the solar plant operated at a CUF of 18.3% over the year.

What is a solar plant performance ratio?

The solar plant performance ratio is a key metric for evaluating the efficiency of a solar installation. It calculates the ratio between the actual energy output and the theoretical maximum output based on the solar energy received.
