Short answer: No. With a grid-tied system, Solar does not generate electricity when there is a grid failure or disconnection. This is an important safety safety feature as during power outages, utility repair crews safety can be threatened if there is a local power generator (such as a solar system) sending power back into the grid lines. For this reason, we design our solar systems to automatically shut down during outages. For clients needing full energy reliability, and experience significant downtime due to blackouts, we do have options that allow for continued solar energy savings during grid failure.
