When Will Solar Microinverters Reach Commercial Scale?:

When Will Solar Microinverters Reach Commercial Scale?:

SolarBridge's Lawrence argues in favor of microinverters on an operations & maintenance basis. Central inverters account for half of an operations & maintenance budget and it's the single highest failure component in a solar PV system; that's why there's been a shift from those to string inverters on commercial-scale solar. "All the reasons you'd do that, are the exact same reasons to go from string inverters to microinverters," he said. "You want as much redundancy and granularity as you can possibly get, to maximize your rooftop utilization and simplify your O&M." Factoring in replacement costs, labor savings in not having work with high-voltage DC, "for most of our customers that alone is enough to justify the additional [price] premium." With a microinverter you'll know when (and which) one panel is underperforming, and it might be tolerable to just leave it alone; on ...
