When solar panel replacement makes sense

Solar panel replacement usually comes up when systems are older, damaged, or no longer supported by manufacturers. Panels crack, glass delaminates, or production drops so low that repairs don’t move the needle anymore. Some homeowners find out their inverter or panels can’t be serviced at all because parts aren’t made anymore.

At McKay Roofing and Solar, we also see replacement after storm damage or failed installs from years back. In those cases, replacing panels can be more reliable than chasing ongoing issues with solar panel repair that never fully solve the problem.

What solar panel replacement includes

Solar panel replacement starts with evaluating the existing system, roof condition, and electrical setup. Panels are removed carefully, mounts and wiring are inspected, and the roof underneath is checked before anything new goes on. That step matters more than people expect.

New panels are selected based on roof layout, sun exposure, and electrical capacity. Replacement isn’t just swapping equipment. It’s correcting old layout issues and bringing the system up to current solar installation standards so it performs better than what was there before.

How long solar panel replacement takes

Most residential solar panel replacement projects take one to two days once everything is scheduled. Timing depends on system size, roof type, and whether roof work needs to happen during the process.

If roof repairs are needed, those are handled first through our Roofing Service San Diego team. Planning roofing and solar together keeps replacement from dragging out and avoids tearing work back apart later.

Common reasons panels get replaced in San Diego

Heat plays a big role here. Years of constant sun degrade materials faster than advertised. Older panels lose efficiency, seals break down, and damage adds up quietly over time.

We also replace panels that were installed without considering roof movement or service access. Those systems are harder to repair and more likely to fail again. Replacement gives the chance to fix those mistakes and reset the system correctly.

Solar panel replacement vs repair

Not every system needs replacement. Many issues can still be handled with solar panel repair if equipment is supported and damage is limited. That’s always the first thing we look at.

When repairs keep stacking up or performance stays low, replacement usually makes more sense. Solar panel replacement draws a clear line between fixing what’s left and investing in something that will actually perform for years.

Solar panel replacement and roof condition

Replacing solar panels without checking the roof causes problems later. If the roof is near the end of its life, panels will need to come off again sooner than expected.

That’s why roof condition is always part of the conversation. As a Solar Energy Company San Diego homeowners already trust for roofing too, we look at the whole setup so replacement doesn’t create another project down the road.
