Before the season: check the structure
Strong pre-monsoon winds can lift panels that are poorly fixed. Before the season, have a mistri check that the frame is bolted firmly to the roof, that clamps are tight and that nothing is rusting through.
- Tight bolts and clamps on every panel.
- No cracks in the roof where the frame is fixed.
- Cables tied neatly, not hanging or rubbing on sharp edges.
- Good earthing for the frame and the system.
During a storm
- Stay off the roof. Don't try to hold or cover panels in high wind.
- During heavy lightning, keep away from the inverter and battery area.
- If water is entering the inverter or battery room, switch off from the main breaker only if you can do it safely and with dry hands.
After the storm
- Look from a safe place for broken glass, bent frames or loose cables before switching on.
- Don't touch damaged panels or cables: broken panels can still produce voltage in daylight.
- If the inverter or battery got wet, don't switch it on. Call a mistri.
- Clean the mud film once things are safe; output often drops after dusty rain.
