recently while purchasing a second hand mower the seller mentioned his solar system. the discussion led to fact they were aware of two pv panels with only 2/3 the rated voltage. we advised to replace pv panels as this was probably from shorted diodes and could over heat and catch roof on fire. they are under a 25 year warranty contract and very pleased with the warranty service installer is providing. i would be worried that this warranty service provider is not changing those known faulty pv panels. those worried about faulty pv panels protect your roof from fire.
