Annual solar panel maintenance guide

Visual inspection, cleaning, performance checks, and service planning.

Annual maintenance keeps solar production predictable. The basic checklist includes visual inspection, cable and connector review, inverter logs, cleaning needs, and production comparison.

Cleaning frequency depends on dust, pollen, bird activity, and rainfall. Unnecessary cleaning can be avoided with production monitoring.

Turuncu Solar recommends documenting each maintenance visit with photos, measurements, and action notes.
