Each panel was originaly putting out .93 Amps now they are only giving .23 Amps each. Made in China.

In most cases the warranty is declaring the module will maintain a minimum % of declared efficiency at the end of that warranty period. Typically 80% of rated power, if I recall. So it's not like after 20 years the module will be 'junk'. Just not as good as it once was...
