Solar and storage: understand the roles before you plan
Solar production and energy storage address different questions. Solar can produce energy when conditions allow. Storage can hold energy for later use, subject to the specific equipment, capacity, power, control, and safety limits involved.
What you can find here
Capacity and power are different: Capacity describes how much energy a storage system can hold, often in kilowatt-hours. Power describes how quickly it can deliver energy, often in kilowatts. A useful plan needs both because the loads you want to support may have different power needs and durations.

Start with priority loads: Rather than asking how much backup every home needs, list the loads that matter to you during an interruption. The answer may include communications, lighting, refrigeration, medical needs, heating or cooling considerations, or other priorities. Specific product capability and site requirements must be verified before relying on an outage plan.

Use safety and product guidance first: Storage involves equipment-specific limits and setup instructions. Do not assume that a general description of storage means a particular product can operate a particular load or provide backup in every situation.
