What Does an Off-Grid Solar System Cost?

At BC Solar, we get a lot of questions about off-grid solar. The biggest one? “How much does it cost?”

If you're exploring an off-grid solar system for your home or business in Columbus, Ohio, here’s what you need to know: no fluff, just honest answers.

What Is an Off-Grid Solar System?

An off-grid system works completely independently of the utility grid. That means:

• Solar panels generate electricity.

• Batteries store the energy for night or cloudy days.

• Inverters convert the power to run your home or business.

• Backup generators (optional) can help in extended cloudy periods.

Unlike grid-tied systems, off-grid setups are all about full energy independence. That comes with major benefits and a higher upfront investment.

The Real Cost of Off-Grid Solar in Columbus

The average cost of a full off-grid system in Central Ohio ranges from $30,000 to $70,000, depending on:

1. Energy Needs

Your energy usage dictates how many panels, how much battery capacity, and how large of an inverter you’ll need.

• Modest cabin? ~$25K

• Average home? ~$45–55K

• Larger homes, farms, or small commercial buildings? $60K+

2. Battery Bank

Batteries are the single largest cost. At BC Solar, we often use Sol-Ark inverters paired with lithium iron phosphate (LiFePO4) batteries for their reliability and long life.

• Entry setups start around $12,000 for batteries alone.

• More robust systems with multiple battery units can reach $30,000+.

3. System Design & Installation

Every off-grid system we build is custom. There's no one-size-fits-all. We consider:

• Your location and sun exposure

• Roof vs. ground mounts

• Backup needs

• Long-term reliability

That’s why we’re battery agnostic and component neutral — we design what fits your situation, not what earns us the highest margin.

Are Off-Grid Systems Worth the Cost?

For some, yes — absolutely.

You should consider going off-grid if:

• You live in a rural area where power is unreliable or nonexistent

• You value total energy independence

• You want to avoid utility rate hikes

• You’re building a self-sustaining home or cabin

We’ve installed off-grid systems for everything from new home builds to remote barns and tiny homes across Ohio.

Financial Support for Off-Grid Solar

You can still qualify for the federal solar tax credit currently 30% off your total system cost. Even off-grid.

Ohio doesn’t offer a state-specific incentive, but we can help you tap into USDA grants, depreciation advantages (for businesses), and financing options that work without gimmicks.

FAQ

How much battery storage do I need for an off-grid home?
Most homes need 2–3 days of energy storage. That often means 20–40 kWh of battery capacity, depending on usage.

Can I add more panels or batteries later?
Yes. BC Solar designs modular systems you can expand over time.

Is an off-grid system more expensive than grid-tied?
Yes mainly due to the batteries. But if you're in a location where bringing in utility lines costs $15,000–$40,000, going off-grid can actually save money.
