I have to disagree with you there... they're not that expensive, and they eliminate the most common single point of failure in the system. When I installed mine last year, I got quotes from every major supplier: I paid a roughly 10% premium for panels with microinverters over a traditional system. We're talking about extending the time it takes for panels that will work for 20+ years to pay for themselves by a few months, in exchange for a massive increase in redundancy: that was an obvious decision from my point of view.
