Are photovoltaic plant capacity values accurate?

This research paper addresses the inaccuracies in the current methods for estimating the capacity value of photovoltaic (PV) plants, which rely heavily on large-scale data and fail to represent the actual capacity value pattern accurately.

Can photovoltaics improve the capacity value of PV power plants?

The coupling of photovoltaics with energy-storage technologies, particularly battery systems, has shown promise in improving the capacity value of PV power plants. Energy storage helps smooth out the variability and intermittency of PV power, increasing its reliability and, consequently, its capacity value. [ 14]

Do different production patterns influence the capacity value of PV power plant units?

1) When comparing scenarios 1 and 2, it becomes evident that differing solar production patterns notably influence the capacity value of the PV power plant unit despite having the same load profile. Figure 1d illustrates the production pattern of the PV power plant unit in Belgium and Texas.

Will PV power capacity grow in the future?

A significant growth of PV power capacity in the future is predicted by all scenarios, regardless of the existing differences in the deployment pathways and ambitions. Total electricity generation in 2021 was 27,813 TWh and would have required a PV capacity of about 20.2 TWp.

What is the capacity factor of a PV system?

Alongside the decrease in installed costs, the global weighted average capacity factor of utility-scale PV systems has been increasing. Between 2010 and 2018 capacity factors increased from an average of 14% to 18%.

Does the rated capacity of a PV unit affect approximation methods?

This graph illustrates how the capacity value of each megawatt (MW) of a PV unit fluctuates in response to changes in the rated capacity of the PV unit. The results demonstrate that approximation methods are not highly affected by changing the rated capacity of PV units, while the exact methods vary significantly.
