Battery vs. Generator: Which Backup Power Option Is Right for You?

When the grid goes down, how will you keep your home or business running?

At BC Solar, we often hear this question:
“What’s better — a battery or a generator for backup power?”

Here’s a quick breakdown so you can make the right choice for your energy needs.

Why Batteries Win for Most Homeowners

Battery storage systems offer key advantages, especially when paired with solar:

• Clean & Quiet
  No fuel. No fumes. No noise. Just seamless backup.

• Automatic Response
  When the grid fails, your battery system kicks in instantly — your lights won’t even flicker.

• Low Maintenance
  No oil changes. No moving parts. Just reliable power when you need it.

• Free Recharge with Solar
  If you’ve got a solar array, your battery recharges daily — no gas station runs required.

• Smart Energy Use
  Many batteries, like those we install with Sol-Ark inverters, can power just critical loads or your whole home depending on your system setup.

Where Generators Still Make Sense

Gas or propane-powered generators can be useful in certain situations:

• Lower Upfront Cost
  Typically less expensive to install initially (though fuel and maintenance costs add up over time).

• Extended Runtime (with fuel)
  Good for longer outages — as long as you can refuel.

• Rural or Off-Grid Settings
  If solar + battery isn’t feasible due to roof size or budget, a generator may bridge the gap.

But here’s the catch:

• Generators are noisy, require routine maintenance, and emit carbon monoxide — meaning they need to be placed outdoors, away from windows.

• Fuel shortages during emergencies can leave you stranded.

Why Columbus Homeowners Are Choosing Batteries

At BC Solar, more of our residential and commercial clients are opting for solar battery storage over traditional generators — and for good reason:

• Peace of Mind
  Whether it’s a winter ice storm or summer grid failure, your home stays powered — quietly and cleanly.

• Sustainable Choice
  Batteries align with your solar investment and your values: clean, renewable energy without emissions.

• Incentives Still Apply
  The 30% Federal Solar Tax Credit applies to battery systems when paired with solar in Ohio.

Real Example from a Local Project

Megan C. in Columbus added a third battery to her system after experiencing a utility outage. As she said:

“We wanted peace of mind — no matter how long the power is out, we’re covered.”

FAQs

How long will a solar battery last during a power outage?
That depends on the size of your system and how much you're powering. Most homeowners cover essentials (fridge, lights, furnace fan, Wi-Fi) for 1–3 days.

Can I add a battery to my existing solar system?
Yes. We’ve retrofitted several Columbus-area systems with batteries, depending on your inverter.

What maintenance does a battery need?
Almost none. Just an occasional firmware update — which we handle for you.

Is it better to have both a battery and a generator?
Not usually. A well-designed solar + battery system can cover most needs. We’ll help you model your usage to make the right call.
