How long can a solar battery power a house? The answer varies depending on the size of your battery and how much energy your home consumes. 

Solar energy experts can help you crunch the numbers. Once you finish reading, hire a technician to learn the pros and cons of solar batteries.

How Long Does the Average Solar Battery Last?

Not every solar battery stores the same amount of power. For example, some units have a capacity of five kilowatts per hour (kWh), while others can store as high as 20 kWh. 

Still, the average battery capacity is around 10 kilowatts per hour. With these units, you can typically keep your essential appliances running for an entire day.

If your home uses a lot of electricity, it may be wise to turn off some non-essential appliances. Alternatively, consider installing more than one battery to increase your power storage.

Estimating Power Usage

It can be challenging to determine how much power your home consumes. Here are a few numbers to consider:

Kitchen

Kitchen appliances, such as refrigerators and ovens, can consume 1 to 2.5 kWh each.

Smaller machines, like coffee makers and toasters, may only consume around 100 to 300 Watts during every use. 

Expect your kitchen to consume between 1 and 3 kWh daily.

Plumbing and HVAC

Hot water and HVAC systems usually consume the most power in a home. For example, a water heater may use 4 to 5 kWh per three hours. 

Central air conditioning and furnaces can consume anywhere from 1 to 10 kWh per hour, depending on your settings. As you can see, these appliances could sap the power from the average 10 kWh battery before the day is over. 

Lights

How long can a solar battery power a house if you keep the lights on?

Despite being essential for day-to-day life, lights typically consume the least electricity in the house. Some bulbs require only 15 to 40 watts of power every hour. 

Suppose your utility company is slow to restore power during a blackout. Assuming you are conservative with your other appliances, you may be able to keep your home lit for several days with a single solar battery.

Entertainment

TVs, Wi-Fi routers, laptops, and other common entertainment devices also consume little power compared to your kitchen and plumbing. Most of these electronics consume at most 50 Watts per hour each.
