Capacity — the amount of energy a battery can store — is one of the main features that influence how long a battery can power a house during a power outage. Battery capacity is measured in kilowatt-hours (kWh) and can vary from as little as 1 kWh to 18 kWh.
Without running AC or electric heat, a 10 kWh battery alone can power the critical electrical systems in an average house for at least 24 hours, and longer with careful budgeting. When paired with solar panels, battery storage can power more electrical systems and provide backup electricity for even longer.
When paired with solar panels, battery storage can power more electrical systems and provide backup electricity for even longer. In fact, a recent study by the Lawrence Berkeley National Laboratory found that when heating and cooling are excluded:
When you pair solar with storage, you can provide backup power to your home indefinitely, as long as the sun rises. Even if you have a cloudy day or two, once the sun starts shining in full again, you can recharge your battery and keep your home powered even if the rest of your block remains stuck in the dark.
But if you experience longer-duration outages–reaching a day or more–a standalone battery isn't the right solution for backup power. In that scenario, it's best to pair a battery with a solar panel system. When you pair solar with storage, you can provide backup power to your home indefinitely, as long as the sun rises.
Solar panel systems are measured in kilowatts (kW) which represent the amount of energy the system can produce in an hour of peak sunlight. So a 5 kW solar system can produce 5 kWh of electricity per hour in ideal conditions. However, since conditions aren’t always ideal, we typically assume a performance ratio of 75%.
