Caring for your rooftop solar panels
Solar panels are a long-term asset. A few simple habits keep them making full units year after year.
Clean the panels every 2–4 weeks
Dust and salt reduce how much sun reaches the cells. Rinse the panels with plain water every 2–4 weeks; near the sea, lean on the shorter side. Early morning or evening is best, when the panels are cool. Don't use soap or hard brushes — they can scratch the glass.
What to watch after a monsoon or cyclone
- Walk around and look for anything leaning, moved or wet in the inverter area.
- Check your meter and your inverter screen; a sudden drop in generation often means a tripped breaker.
- Report anything unusual to us on WhatsApp; we come out and check.
Warranties on your side
- Panel maker's performance warranty (typically 25 years at falling capacity).
- Inverter warranty (5+ years from the maker).
- Our 5-year system warranty, in writing on your contract.
Questions people ask
How often should I clean rooftop solar panels in Pondicherry?
Every 2–4 weeks with plain water. Near the sea, every 2 weeks is safer because salt builds up faster. Avoid soap and hard brushes.
Do I need an AMC?
Every Sunwon system comes with a free 5-year AMC: cleaning, health checks and service. After that you can renew if you wish.
What should I do during a cyclone warning?
Nothing special needs to be done; our hot-dip galvanised structures are designed for coastal wind and anchored properly. Afterwards, check that the inverter shows normal generation and WhatsApp us if anything looks wrong.
