The underground scope on your solar job
Apex is the underground sub for solar EPCs, developers and electrical contractors. We bore and trench the conduit that ties arrays, carports, battery storage and EV chargers back to the switchgear and the utility, under live parking lots and finished landscaping.

Built for the people who build solar
Solar EPCs & Installers
Hand us the underground package so your crews stay on racking, modules and terminations.
Developers & PPA Providers
A fixed scope from one licensed sub, priced from your plan set before you lock the budget.
Electrical Contractors
We set and prove the conduit. You pull wire. Depth, bends and stub-ups match your drawings.
Ag & Commercial Owners
Ground mounts across fields, canopies over parking, storage next to the service. We keep the site running while we work.
Conduit sweeps stubbed up at a carport column footing
Array to switchgear to the utility
DC & AC collection conduit HDD
Long bores under drive aisles, parking fields, roads and landscaping between arrays, inverters and switchgear. No saw cutting and no repaving.
Carport & canopy feeds HDD · Trench
Runs between canopy columns, with sweeps and stub-ups set at the footings to your electrical drawings.
Battery storage (BESS) HDD · Trench
Feeders and comms conduit to battery cabinets and containers, including pad prep tie-ins and grounding trench.
Utility interconnection PG&E OQ
Applicant-side trench, conduit and vault work to the point of interconnection, built to the PG&E construction sketch.
EV charger conduit HDD
Feeds to Level 2 and DC fast chargers, often on the same mobilization as the solar carport.
HDPE fusion & conduit bundles Fusion
Butt-fused HDPE and multi-duct bundles for long pulls with fewer joints in the ground.
Hydrovac potholing Locate
Daylighting existing utilities at every crossing before the drill goes under them.
Fiber, SCADA & monitoring HDD
Low-voltage and fiber conduit for metering, monitoring and site controls.
Nine rigs, 8,000 to 60,000 lb class
Apex and our partner crews run compact drills for tight carport rows and all-terrain rock drills for long runs to the point of interconnection. We match the rig to the bore length, conduit bundle and ground conditions.
Solar sites are already built
Carports go over parking that people use every day. Ground mounts go across fields with irrigation, drainage and existing services. Boring keeps the conduit route off the surface.
Open trench
- Saw cut, haul off, backfill, compact, repave
- Parking rows closed for days
- Landscaping and irrigation torn out
Directional bore
- Entry and exit pits only
- Lot stays open around the rig
- Depth tracked the whole length of the bore
From plan set to pulled conduit
Takeoff
Send the site plan and electrical sheets. We return bore and trench footage by run, conduit size and count, with a price.
Locate & pothole
USA 811 ticket, then hydrovac at every crossing so the bore path is verified before we drill.
Bore & pull
Pilot bore, ream and pullback to the depth on your drawings. Sweeps and stub-ups set where you need them.
Turn over
Conduit mandreled with pull rope in place, plus bore logs and as-built footage for your closeout package.
