Quick answer
The practical explanation
A string inverter converts power from a group of connected panels at one central unit. Microinverters are installed at individual panels. Each architecture has different design, monitoring, service-access, shade-response, and cost considerations.
What to know
Three points to keep in mind
- The better choice depends on the roof and system design.
- Panel-level electronics can provide panel-level monitoring.
- Ask how equipment location affects future access and replacement.
For your home
A site-specific answer still matters
