Effective utilization hours of solar power generation

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:

What is the array efficiency of a solar power plant?

The array efficiency ( ηa) of a solar power plant is the ratio of the effective DC energy generated ( Eefdc – kWh) to the mean daily in plane solar irradiation ‘ Hm ’ in kWh/m 2 at the installation site and is given in ( 27 ). The value of ‘ Hm ’ for the test site is found to be 5.21 kWh/m 2 [ 55 ]

What are the benefits of solar residual energy utilization systems?

In comparison to the prototype solar thermal system only used in the heating season, the solar seasonal residual energy utilization systems can raise the solar effective year-round efficiency substantially, i.e. 69.12% and 18.65% for systems A and B. Moreover, the solar effective utilization hours will also be enhanced by 2.63-fold. 3.

How much solar energy is available over a monitoring period?

The array yield of the traditional and MISPVS during the monitoring period is obtained as 1278.28 kWh/kW p /year and 1661.14 kWh/kW p /year with a daily average yield of 3.50 and 4.55 kWh/ kW p, respectively. The reference yield indicates the theoretical solar energy available at a test site over a monitoring period.

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.

Can seasonal-regulatable solar energy systems solve the solar residual energy unemployment problem?

In summary, the implementation of seasonal-regulatable solar energy systems can solve the solar seasonal residual energy unemployment problem to varying degrees, thereby making the best use of solar energy in the whole year. Through the exploration and comparison of these newly proposed energy systems, the main conclusion can be drawn as follows.
