When a cheap solar system doesn’t stack up

Buying a cheap solar system doesn’t stack,for a few bucks more you can buy a good system.Time and time again I see people buying cheap solar system.They say it is great price great panels good inverter. How comes then I have to fix so money faulty systems?. why is it that so many Chinese inverter company’s have gone out of business?. Or cheap solar panels that discolour, have junction boxes that fall of. Have terminations that have burnt and have tracking under the glass. Our you can clearly see corrosion on metal parts on the inside of the panel.?
