The good news is the solar industry has evolved over the last 10 years and if you would like to generate more power upgrading your solar system from string inverters to.
Maintain solar panel inverters changed after 4 10 years.
However if you re looking for off grid battery based pv inverters you can expect much shorter lifespans ranging from 2 10 years depending on the manufacturer.
Just like any highly technical system the biggest enemy is dust.
Solar panel efficiency and inverter lifespan are directly related to the amount of ongoing maintenance they receive.
This occurs because string inverters treat a group of panels as if it were a single large panel meaning any problems with one panel are felt across the entire string.
Solar inverters lifespan can vary as most string inverters life expectancy ranges from 10 to 15 years whereas some microinverters and dc optimizers are rated to last 20 to 25 years.
A typical central inverter for a pv installation will last between 10 and 15 years and thus will need to be replaced at some point during the lifetime of your solar panels.
Warranty extensions for inverters are a smart investment.
Replace inverters after 10 years.
It s safe to assume you ll replace your inverter at least once before the warranty on your panels is up.
Ja solar say it doesn t affect the output of the system which i do not believe only after 3 years so you can imagine what they will look like after 10 or 20 years let alone their performance.
However micro inverters are a new and popular alternative to central inverters and generally offer the same lifespan as their solar panel counterparts 25 years.
