Solar reduces daytime grid dependence. Generators protect critical loads when the grid fails. Many sites need a clear package that combines both rather than treating them as rivals.
Use solar for daytime production
Solar is strongest when sized to real daytime demand and mounting conditions. It is not automatically a full outage solution on its own.
Use generators for critical continuity
Backup generation should be sized from the loads that must stay online — not from the entire building by default.
Plan them as one continuity conversation
When solar and generators are scoped together, handover is clearer and the site avoids buying two disconnected systems that fight each other operationally.
