In the previous article we have discussed solar panel warranties. In this article we will discuss inverter related warranties, risks associated with them and strategies how to mitigate these risks.
Inverters: Manufacturer's warranty. Almost all manufacturers of inverters offer the same warranty. For inverters, the industry standard is 5 years on parts and labours. It is well known that typical lifetime of inverter is around 15-20 years. Thus, there is a possibility that you need to change an inverter during the 20 year timeframe (e.g. span of FIT contracts in Ontario). Thus, you can consider buying extended warranty or inverters with warranty above the industry standards (obviously they cost more).
Inverters: Waiving of warranty due to manufacturer's bankruptcy. There is a possibility that inverter manufacturer will go out of business and will not honor the warranty. Unlike solar panel industry with hundreds (if not thousands) suppliers, the inverter industry has not more than 10 major players with well established market shares. Thus, a possibility that a manufacturer will go out of business within warranty lifespan and will not honor warranty is pretty remote.
