The microinverter game has both ups and downs.

While it's true that they help with a single panel failing, and not causing issues for the whole array, you also now have that many inverters that can fail. Generally, due to the pricing game that everything comes down to, the microinverters are not as robust and reliable as good quality Outback, Schneider, etc inverters.

It also means that you have 120 or 240 VAC (depending on the panel and inverters) running all over your roof. As a counter point, most MPPT solar arrays are going to be running up to 150VDC.
