Ja solar has a major problem with snail trails marks under the surface glass and on top of the cells of their panels.
Maintain solar panel inverters changed after 4 10 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.
And anywhere batteries are present and electricity is flowing in the possible presence of moisture the risk of corrosion increases too.
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.
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.
Most grid tie inverters have a 10 year warranty and many manufacturers give the option to upgrade to 20 to 25 year warranty coverage.
Warranty extensions for inverters are a smart investment.
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.
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.
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.
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.
