Off-Grid Solar Systems vs. Grid-Tied: What's the Difference?

Thinking about going solar in Columbus, Ohio? One of the first decisions you’ll face is whether to go with an off-grid or grid-tied system. It’s a big one—and it comes down to how much independence you want from your utility company.

Let’s break it down.

How Does an Off-Grid System Differ from a Grid-Tied System?

Grid-Tied Solar:

• Connected to the utility grid

• You can sell excess electricity back (via net metering)

• You still rely on the power company when the sun isn’t shining

• Typically no batteries unless added as backup

Off-Grid Solar:

• Completely independent from the grid

• Uses batteries to store power for nights and cloudy days

• Requires more system planning and capacity sizing

• No backup from the grid — you’re 100% self-sufficient

Off-grid systems offer real freedom—but with freedom comes responsibility. You’ll need to size your system carefully and install enough battery capacity to power your home through Ohio’s cloudy winter weeks.

Is Off-Grid Right for You?

It depends on your goals.

Choose Off-Grid If You:

• Want full control over your power

• Live in a rural area without reliable grid access

• Are prepared to manage energy usage, storage, and backup

Stick With Grid-Tied If You:

• Want to save money and keep it simple

• Prefer utility backup during low-sun periods

• Want to qualify for net metering credits

FAQs

Can I go off-grid in Columbus, Ohio?

Yes, it’s legal—and totally doable. But off-grid systems require permits, proper battery storage, and more detailed planning than grid-tied ones. We can walk you through it.

How much battery storage do I need?

It depends on your energy use and how many days you want to store power. Most off-grid homes in Ohio need enough storage for 2–4 days of use, depending on efficiency and lifestyle.

What happens if I run out of stored power?

With an off-grid system, you’re responsible for your own backup—often a generator or adding more solar/batteries. Planning is key. We help you design for the worst-case weather.
