Solar panel inverters & costs: the expert guide [UK, 2025]

How long do solar panel inverters last? The two main types of solar inverter have varying lifespans. String inverters handle the electricity of an entire solar panel array and typically come with a 10-year or 12-year warranty. In most cases, a string inverter will need replacing at some point during the lifespan of a solar panel system.

7 Reasons Why You Should Oversize Your PV Array

For example, using Sunny Design, a 100kWp PV array with three STP25000TL-30 inverters (i.e. 75kW of inverters) would only produce ~2% less annual energy compared to the same PV array with four STP25000TL-30 inverters (i.e. 100kW of inverters). This means that there is only a ~2% lower energy output for 25% fewer inverters.
