Some company like mine warranty claim no charge BUT labour to dismantle and change got charge.
Also many worried in solar company close shop, who gonna respond to the warranty claim.
So it is nice to get long warranty but the problem is the company handling the warranty sure got labour charge especially if need skylift and most importantly, if company close shop, who gonna handle the warranty claim. Many company no want to handle warranty claim that was installed by other company not related to theirs.
Solar panels also need maintenance once in a while, the cost do adds up but depends on usage, for me, either break even after 10 years or will earn a couple of years of free solar. Better than no solar especially since daytime, my parent also use air cond, the solar daytime generation contra that. Worth it.
Also warranty for PV if spoil but does not cover degradation over the years, sure the performance will drop.
As long as the company exist, no problems no worries. So be smart gets a good one.
How often do you think you need skylift to maintenance your PV if no repair needed?
Solar panels do need washing if your area is dusty, else rain water is good enough ... like mine.
Normally PV will degrade slightly over the year, probably down to 80-85% after 20 years but good enough for me.
Mine ROI done in 4Y3M only..... so probably another 15-20 years FREE electricity.
