In Indore, clean solar panels every two to three weeks from February to June when dust is heaviest, and as needed during winter; monsoon rain does much of the work from July to September. Dust can reduce output by 5–15%. Clean early in the morning with soft water and a soft brush or microfibre mop — no detergents, abrasive powders or high-pressure jets, and never on hot glass. Beyond cleaning, check the monitoring app monthly and get connections, earthing and structure fasteners inspected once a year.

- **Dry season:** Every 2–3 weeks
- **Dust loss:** 5–15%
- **Best time:** Early morning
- **Avoid:** Detergent, jets, hot glass


## Cleaning frequency by season

| Season | Months | Suggested frequency |
|---|---|---|
| Summer / dry | Feb – Jun | Every 2–3 weeks |
| Monsoon | Jul – Sep | Only if visibly dirty (bird droppings) |
| Post-monsoon & winter | Oct – Jan | Every 3–4 weeks |

Near construction sites, main roads or industrial areas, clean more often.

## How to clean — step by step

1. **Morning only.** Hot glass + cold water can stress the glass; afternoon cleaning also leaves water spots.
2. **Isolate if advised** by your installer (DC isolator), especially for hose use near connectors.
3. **Rinse** with low-pressure water to loosen dust.
4. **Wipe** with a soft brush or microfibre mop on a pole.
5. **Rinse again** and let dry. In hard-water areas, a final wipe prevents scale.

## Never do this

- Detergents, soap, surf or abrasive powders
- High-pressure jets on the glass or into junction boxes
- Walking or standing on modules
- Metal scrapers on bird droppings — soak and wipe instead

## Hard borewell water

Indore borewell water is often hard. Repeated use leaves white scale that cuts light. Use softer water if available, or wipe dry after rinsing.

## Yearly maintenance checklist

- Tightness of structure bolts and module clamps
- Rust touch-up on any cut or scratched steel
- Cable condition, conduit and ties (UV damage, rodents)
- MC4 connectors — no discolouration or heat marks
- Earthing continuity and lightning arrester
- Inverter error log and generation vs last year
