Yes, in most cases replacing an ageing inverter is well worth it. The inverter is the component most likely to need replacement during the lifespan of your solar system.
Why replace rather than repair:
- End of life — inverters typically last 10–15 years. If yours is 10+ years old and failing, a repair may only buy you a short time before the next fault.
- Improved efficiency — modern inverters convert solar power to usable electricity more efficiently than older models
- Better monitoring — new inverters come with internet-connected monitoring, giving you real-time visibility of your system’s performance via an app
- Battery-ready — modern hybrid inverters can manage both solar panels and a battery in one unit. If you think you might add a battery in the future, a hybrid inverter now means one fewer upgrade later.
Cost vs benefit:
- A replacement inverter typically costs £800–£2,000 depending on the size and type
- Your existing solar panels likely have 15–20+ years of life remaining
- A new inverter restores full performance for those remaining years and may unlock additional savings if you add battery storage
