Do photovoltaic systems need maintenance?

The expansion of photovoltaic systems emphasizes the crucial requirement for effective operations and maintenance, drawing insights from advanced maintenance approaches evident in the wind industry. This review systematically explores the existing literature on the management of photovoltaic operation and maintenance.

What is operation & maintenance (O&M) of photovoltaic (PV) systems?

This guide considers Operation and Maintenance (O&M) of photovoltaic (PV) systems with the goal of reducing the cost of O&M and increasing its effectiveness. Reported O&M costs vary widely, and a more standardized approach to planning and delivering O&M can make costs more predictable.

What is the maintenance strategy of photovoltaic power generation system?

At present, according to the differences in the composition of the components of the photovoltaic power generation system, the maintenance strategy can be divided into post-maintenance and preventive maintenance strategies for single components and opportunistic maintenance strategies for multiple components.

Do photovoltaic power generation systems need a single-component maintenance scheme?

Through the above literature, it can be seen that the current maintenance scheme of photovoltaic power generation systems is mainly aimed at single-component maintenance. Although the opportunistic maintenance between multiple components is partially considered, most of them are based on the time dimension.

Why is maintenance management important for PV power plants?

Therefore, maintenance management is essential for reliable and effective operation of PV power plants, ensuring uninterrupted system operation and minimizing downtime. Compared to well-established technologies such as hydro, thermal, and wind, the O&M processes for PV systems are not yet fully structured in many operating companies .

How does transformer maintenance affect a photovoltaic power generation system?

In the same way, the number of transformer maintenance in the photovoltaic power generation system is the least, and the maintenance cost accounts for a relatively low proportion in the whole system, so the impact on the average maintenance cost change rate of the system is low when it changes.
