Older solar systems still work, but many are producing well below what modern panels can deliver on the same roof. Replacement makes sense when the numbers stop adding up or the hardware is aging out.

When panel replacement is worth it

If your system is 12–15+ years old, has failing inverters, damaged panels or is producing noticeably less than it used to, replacement is usually worth pricing out. Newer panels squeeze more energy out of the same roof space.

It's also common to replace older systems when you're upgrading the roof itself – doing both at once is cheaper than doing them a year apart.

Panels bought before around 2015 are also a full generation behind on efficiency, which matters more now under NEM 3.0 since maximizing daytime self-consumption is worth more than it used to be. Swapping a 15%-efficient legacy panel for a modern 21–22% panel can meaningfully shrink the footprint needed to cover the same usage.

What replacement includes

We remove the existing panels, racking and wiring, inspect the roof underneath, and address any issues before the new system goes back up. New racking, panels, inverters and monitoring get installed with fresh flashings and sealed penetrations.

We handle permits and utility re-interconnection so the new system gets approved to operate the right way.

Because we're a licensed roofing crew as well, tile and shingle repair under the old mounting points happens as part of the same visit – no separate contractor, no gap between removal and re-install where the roof sits exposed.

Pairing replacement with a new roof

If your roof is close to end-of-life, replacing panels without addressing the roof usually means paying to detach and re-set the array again in a few years. We can bundle the roof and solar together so it's done cleanly, once.

This is the most cost-effective time to fix roof issues, since the array is already off and the roof surface is fully exposed – there's no premium for working around panels that are staying put.

Adding battery storage during replacement

Replacement is a natural time to add batteries. New system design, new inverter, and battery integration can all be planned together for a cleaner install and better long-term performance.

NEM interconnection changes during replacement

Swapping panels or expanding a system can trigger a new interconnection review with your utility, and depending on the scope it may move your account onto NEM 3.0 rules if you're not already on them. We walk through what that means for your specific bill before we finalize a design, so there are no surprises on the export credit rate after the switch flips on.

What to do with old panels

Panels removed during a replacement still have real value in some cases – functioning older panels can sometimes be repurposed for a shed, detached garage or well-shaded secondary structure where peak efficiency doesn't matter as much. Where reuse doesn't make sense, we handle responsible recycling instead of letting them pile up in a garage.
