What are the four essential types of maintenance required for a solar PV system?

Maintaining a solar PV system effectively involves several critical processes:

• Conducting an electrical inspection to ensure all solar array strings are functioning correctly.
• Performing an interior inspection of all related equipment such as inverters, switches, and connection boxes.
• If applicable, carrying out battery maintenance or a detailed battery inspection.
• Using infrared tools to inspect electrical connections for any loose connections or hot spots.
