| Interval | Task |
|---|---|
| Middle East: Monthly, or after dust storms South Asia: Every 2 to 3 months, and before the monsoon Europe, USA: Every 6 to 12 months | Clean the panel with water and a soft brush |
| Yearly | Check panel angle, bracket bolts, cables, and seals. Cut back trees that shade the panel. |
| Yearly | Read battery health from the controller. Test autonomy on a sample. |
| 5 to 8 years | Replace batteries by condition, as a planned group job |
