Frequently asked questions
Do I need solar to add battery storage?
Not always. Some homeowners add storage mainly for resilience and backup planning, even before installing solar.

No. Partial backup is often the better balance of cost and resilience for many homes.
What changes battery installer quotes the most?
Coverage goals, output requirements, critical-load planning, and how the battery integrates with the existing electrical system.
