Maintaining and caring for your solar system — ensuring a 25-year service life
PV, inverters, storage: What needs to be checked regularly so that your system delivers full performance.
Solar systems require less maintenance than most household appliances. But: these few maintenance appointments determine whether you get 15 or 25 years of performance.
What needs to be checked
- PV modules: Visual inspection annually, cleaning every 2–4 years. - Inverter: Maintenance every 5 years, lifespan 10–15 years. - Battery storage: Annual check. - Wiring: Inspected by a professional every 2–3 years.
What you can do yourself
1. Keep an eye on the monitoring. 2. Visual inspection after storms. 3. Keep inverter ventilation clear.
