Operation and maintenance of chemical solar container power stations

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 .

What is solar power plant operation?

Operation is about remote monitoring, supervision, and control of the solar PV power plant and it is an increasingly active exercise as grid operators require increasing flexibility from solar power plants. Power plant operation also involves liaising with or coordination of the maintenance team.

What are the maintenance strategies for solar PV systems?

In literature, three general maintenance strategies for solar PV systems are mentioned: corrective, preventive, and predictive maintenance. Fig. 8 shows the evolution of maintenance strategies over time, along with examples of maintenance activities for PV systems. Fig. 8. Evolution of maintenance strategies.

Who should be involved in changes to a solar PV power plant?

The O&M service provider should be involved in changes to the solar PV power plant from the beginning. Concepts, design works, and execution need to be coordinated with ongoing O&M activities. Any changes should also be reflected in the plant SCADA and monitoring systems.

Who should manage the design of a solar PV power plant?

Management of change If the design of a solar PV power plant needs to be adjusted after the Commercial Operation Date, the O&M service provider should, as a best practice, be involved by the Asset Owner and the EPC service provider. They can even be a main contributor, if not the leader, of this change process.

What is preventive maintenance in a solar plant?

Preventive Maintenance are the core elements of the maintenance services to a PV plant. It comprises regular visual and physical inspections, as well as verification that all the key components of the solar plant are in good working order.
