What you'll find here are primarily on-grid folks. Also you'll find folks that primarily are retrofitting a PV system to an existing roof . That requires adjusting for less than optimal panel siting. And that's where the conversations normally start to look like spaghetti.
A properly sited system has no shading and therefore doesn't need work-arounds to minimize the damage shading causes.
Another argument you'll find from the micro-inverter crowd is that micros allow each panel to work independently and provide max energy harvest. Except that most of the microinverters are installed on oversized panels - so the max collection days are limited by the smaller inverter, not the capability of the panel.
One cool thing about microinverters is the per-panel monitoring that gives the instant-gratification smart phone crowd pretty pictures to look at. Yes, there are per-panel MPPT devices like the Tigo maximizers that provide panel-level data and panel-specific energy harvesting should one be forced to work around shading. But that's market driven, not because of some failure of central or string inverters. Put another way, a PV system is a marathon, not a sprint. Annual inspection and preventive maintenance is normally sufficient.
Nothing made by man is perfect, and hot electronics are not happy electronics. At some point inverters will fail. My personal choice is a central inverter that's mounted at chest-height. It can be gutted and completely rebuilt in less than one hour if necessary. Because the devices are normally placed in better environments than rooftops, they normally don't require rebuilding very often. http://www.mynissanleaf.com/viewtopic.php?f=45&t=10736http://www.mynissanleaf.com/viewtopic.php?f=45&t=11807http://www.mynissanleaf.com/viewtopic.php?f=45&t=12282http://www.mynissanleaf.com/viewtopic.php?f=45&t=11966
You can use microinverters, a central inverter, or a hybrid system with individual MPPT units and a central inverter. They'll likely give similar service in both harvest and lifespan. It'll most likely come down to what your local installers are used to working with and what they charge for labor. Installers generally like micros because they can do the job faster yet get the same income from the installation - they generally push them because it's better for them, not necessarily better for you.
