What is the expected lifespan of a solar system?
Industry standards and expectations show that most solar panels in the market should expect to have a life span of at least 25 years with some panels still fully operational closer to 50 years after they were installed. There will always be exceptions to this rule with lower quality panel manufacturers that have taken shortcuts and shown issues well before this timeframe. Therefore, installing a reputable solar panel manufacturer is very important and highly recommended. Inverters are more involved in the technology required to build them and have more components that have the ability to fault in the future. The more you stick to a reputable manufacturer the better chance you have on having less issue in the future, there is no real timeframe of expectations of lifespan of the inverters as some inverters may only last a couple of years but better quality inverters lasting closer to 7-15 years.
