Life expectancy of rooftop solar panels.
These batteries create electricity through chemical reaction between lead plates within the battery and sulfuric acid that surrounds the plates hence the name lead acid.
This is one more measure of confidence in the solar panel s lifespan but it s expected that panels will still continue to operate for years to come after that warranty expires.
