Can I Expand My Solar + Battery Backup System Later?

Yes — and at BC Solar, we plan for it from the start.

A big concern for many homeowners and business owners around Columbus is whether their solar and battery backup system will be locked in at install. The answer? Not with us. Our systems are built modular and flexible.

What Does "Modular" Really Mean?

It means your system is built like building blocks. You can:

• Add more panels if your energy needs increase.

• Add more batteries for extra storage or longer outages.

• Upgrade inverters or integrate EV chargers down the line.

We install systems that are battery-first and designed with your future goals in mind — whether that's growing your family, electrifying your home, or adding a shop to your property.

Why It Matters for Homeowners in Central Ohio

Energy use can shift fast — and the grid isn't always stable. Having a solar + storage setup you can grow into gives peace of mind.

You might start with:

• A 10 kW system

• One Sol-Ark inverter

• Two lithium batteries

But in 2–3 years, if your usage changes or power outages become more frequent, you can easily expand. You don’t have to rip out what you’ve already paid for.

How BC Solar Builds for Expansion

We think long-term. Here's what we do differently:

• Underspec wiring & conduits for future add-ons

• Battery-agnostic designs (no vendor lock-in)

• Panel spacing & roof layout optimized for future additions

• Inverters chosen with headroom — like Sol-Ark, which handles more than it shows

And just as important — we’ll walk you through the whole process transparently. No surprises, no gimmicks.

Local Example: Westerville Family Upgrade

One of our clients in Westerville installed a modest setup during a home renovation. A year later, they added more panels and a third battery as their usage grew. Because we had planned for expansion, it was fast, seamless, and didn’t require re-permitting or major rework.

FAQ

Can I add more batteries without replacing anything?

Yes. As long as we plan for it up front — which we always do.

Do I need to tell the utility again if I expand?

Maybe. It depends how much you expand. We handle all utility coordination.

Can I use different battery brands later?

Usually yes. We prefer open, battery-agnostic systems like Sol-Ark that allow this flexibility.

What happens if I install a heat pump later?

We can model your increased load and help you decide whether to add panels, batteries, or both. Everything we install can scale.

BC Solar is here to make sure your solar and battery system grows with you — not against you.

We believe in:

• Doing the right thing

• Building for the long haul

• Honesty before hype
