Termites And Modern Home Upgrades: Solar Panels, EV Chargers, And Battery Walls

Solar panels on a gray tile roof reflect sunlight. Below, a patio with a table and chairs is surrounded by a neatly maintained grassy yard.
Adding solar, an EV charger, or a battery wall Changes to wiring, roof, and walls can also change termite risk. Learn what Bay Area homeowners should check before and after modern upgrades.

New Tech, Same Wood Framing

Bay Area homes are changing.

More houses now have:

  • Solar panels on the roof

  • EV chargers in the garage or on exterior walls

  • Battery storage systems in utility areas

  • Extra wiring, conduits, and equipment on walls and in attics


All of this runs through the same wood framing, stucco, and crawlspaces that termites have always liked.


The upgrades themselves do not “cause” termites. But the way they are installed can:

  • Add new penetrations through walls and foundations

  • Change how moisture moves around the house

  • Limit access for future inspections


This post looks at how modern home upgrades intersect with termite risk and what you can do to keep your tech and your structure working together.


Solar Panels And The Roof Structure

Solar panels are usually mounted on rails attached to your roof framing. That means:

  • Hardware penetrations through roofing materials

  • Extra weight on certain rafters or trusses

  • Conduit runs across the roof or through attic spaces


From a termite and wood health perspective, the main concerns are:

  • Moisture

    • Poorly flashed penetrations can leak over time.

    • Slow, small leaks into the attic or wall cavities weaken wood and attract fungus and termites.

  • Access

    • Panels can make parts of the roof harder to inspect from above.

    • If your attic is already tight, new wiring and hardware can limit where inspectors can move.


What you can do:

  • Have someone check the attic for staining or moisture under solar penetrations, especially a year or two after install

  • Make sure any roof leaks are fixed fully, not just patched at the surface

  • Ask your termite inspector to pay special attention to roof framing under solar arrays


EV Chargers And New Wall Penetrations

EV chargers are often mounted:

  • On garage walls

  • On exterior walls near driveways

  • On posts near parking spots

They require:

  • New electrical runs

  • Conduit through walls or foundations

  • Sometimes new concrete pads


Termites care about:

  • Gaps around conduits where they can travel from soil into wall cavities

  • New penetrations low on the wall close to grade

  • Changes to soil and slab joints around charger pads


What you can do:

  • Ask your electrician or contractor to seal around all new conduits where they enter walls or foundations

  • Avoid running conduit directly through soil into wood without proper sleeves or seals

  • During inspections, mention where EV lines run and ask for extra attention around those areas


Battery Walls, Inverters, And Utility Clusters

Battery storage systems and inverters are often mounted:

  • On garage walls

  • On exterior stucco near main panels

  • In utility rooms or side yards


These setups can cluster:

  • Heavy equipment on a small section of wall

  • Multiple penetrations for wiring and conduit

  • Concrete pads, cable trays, and protective posts


Risks include:

  • Water pooling around new concrete pads or footings

  • Sealant gaps where multiple conduits pass through the same wall opening

  • Hidden routes for Subterranean termites at grade level just behind equipment


What you can do:

  • Keep soil and mulch down around the base of any new equipment pads

  • Check that wall penetrations are sealed cleanly, not left with rough openings

  • Make sure there is enough clearance for inspections behind or below equipment where practical


When To Time Your Termite Inspection Around Upgrades

You do not need a termite inspection for every new outlet, but larger projects are a different story.


Smart timing:

  • Before a major upgrade

    • Have the structure checked so you know whether any termite or fungus issues already exist near planned work.

    • This helps avoid installing expensive equipment on compromised framing.

  • After installation

    • Once work is complete and any drywall or stucco patches are done, schedule another inspection focused on:

      • New penetrations

      • Roof framing around solar

      • Wall and foundation interfaces near EV and battery locations


This is especially helpful if:

  • Your home is older

  • Your lot has poor drainage

  • You already had some termite history before the upgrades


How Modern Upgrades Can Limit Or Help Future Inspections

Some installs hide areas. Others make access easier.


They can limit access when:

  • Solar arrays cover most of the roof, making shingle checks difficult from above

  • Battery walls and EV equipment block visual access along key sections of wall

  • New framing or platforms are added in tight garages without leaving inspection space


They can help when:

  • New work exposes wall cavities or roof sheathing, giving a temporary view of hidden areas

  • Contractors remove old, decayed wood and you bring in a termite company to confirm the cause before closing everything up


The main idea is to think of big upgrade projects as a chance to look at the structure, not just the new hardware.


Talking To Contractors About Termites (Without Making It Awkward)

You do not need your solar or EV installer to become a termite expert. A few simple points are enough:

  • Let them know you plan to have a termite inspection after the project is done

  • Ask them to keep penetrations as clean and sealed as possible

  • Request that they avoid burying siding or weep screeds in new concrete or soil

  • If they see soft wood, unusual damage, or mud tubes, ask them to tell you instead of covering it and moving on


Contractors are usually focused on meeting electrical and building codes. Mentioning termites simply helps them think about what they are doing to the structure as a whole.


How Good Sense Termite Handles Homes With Modern Upgrades

When we inspect homes with solar, EV chargers, and battery systems, we:

  • Ask where lines run and where equipment was installed

  • Pay special attention to roof framing under arrays and around penetrations

  • Check walls and foundations at charger and battery locations for cracks, gaps, or moisture

  • Look at drainage and soil contact near any new concrete work


We are not judging your upgrades. We are making sure the structure behind them is healthy.


For homeowners who are not in active escrow, inspections are provided at no cost. For homes in escrow, we offer fee based inspections that meet real estate needs.



FAQ: Termites And Modern Home Tech

Q: Can solar panels cause termites?

A: They do not cause termites, but leaks or moisture around poorly flashed mounts and limited attic access under arrays can create better conditions for termites and fungus if no one checks the area.


Q: Do I need a termite inspection after installing an EV charger?

A: If the work included new penetrations low on exterior walls or changes near soil level, it is smart to include those areas in your next inspection. You may not need a special visit just for the charger, but do not ignore those zones.


Q: Should I delay upgrades until my termite situation is perfect?

A: Not usually. It is more practical to combine upgrades with a clear look at the structure and handle both in a sensible order.


Final Thoughts: Upgrade Your Home Without Forgetting The Frame

Solar, EV chargers, and battery systems are smart investments for many Bay Area homes. They do not have to come with termite surprises.


The key is simple:

  • Know what is happening behind the panels and conduit

  • Keep moisture and soil from quietly changing the rules

  • Use big upgrades as a chance to understand your structure better, not less


If you are planning modern upgrades or already have them and want to know how your framing and foundation are holding up, we can help.


Schedule an inspection with Good Sense Termite. We will look past the hardware and focus on the wood and soil that still matter most.


It's just Good Sense.
