Electrical Engineering · Solar, Storage & EV Charging

Commercial Solar & EV Charging Infrastructure

Solar PV, battery storage, and EV charging for commercial sites in Tucson and across Arizona — engineered in-house and installed by our own CR-11 electrical crews, with the TEP or Trico interconnection handled from day one.

What We Provide

Solar, storage, and charging — designed and built by the same firm

Most commercial solar and EV projects pass through three hands: a developer who sells it, an engineer who stamps it, and an electrician who inherits whatever the first two agreed on. Here, the firm that designs the system installs it — which changes what gets drawn, and what gets built.

Solar PV — Rooftops & Carports

  • Commercial rooftop PV — Array layout, DC/AC system design, and conduit routing planned around the roof itself — penetrations, attachment, and the roofing warranty included.
  • Carport and canopy PV — Generation over parking, with the foundations, steel coordination, and underground feeders handled by the same company that self-performs sitework.
  • Designed for the building's power system — The PV single-line is drawn against the building's actual service and distribution, not bolted on after the fact.

Battery Energy Storage

  • Storage integration — Battery energy-storage systems for demand management, resiliency, and solar pairing, designed into the switchgear rather than around it.
  • Code and siting — Clearances, disconnecting means, and fire-code coordination worked out with the AHJ before equipment is ordered.
  • Resiliency planning — Storage scoped alongside standby power, so the owner buys one coherent backup strategy instead of two competing ones.

Utility Interconnection — TEP & Trico

  • Interconnection applications — We prepare and carry the interconnection package with Tucson Electric Power or Trico Electric Cooperative, and design to the serving utility's requirements from the first drawing.
  • Metering and point of connection — Production metering, disconnect placement, and point-of-connection details settled with the utility before construction.
  • Standards on hand — We work with these requirements daily and keep a TEP standards reference hub our own crews and other contractors use.

EV Charging & Energy Retrofits

  • Level 2 charging — Workplace, fleet, and visitor charging — panel capacity checked, circuits and pathways installed by our own electricians. Our commercial EV charging installation in Tucson page covers the full scope.
  • DC fast charging — Higher-power charging infrastructure, including the service and distribution upgrades it often triggers.
  • Load management — Managed charging that lets a site add chargers without overbuilding the service — often the difference between a panel circuit and a utility service upgrade.
  • Energy retrofits — Lighting, controls, and equipment retrofits that cut consumption and can qualify for utility incentive programs.

Where It Applies

Where this work shows up

Workplaces adding chargers for employees, fleets electrifying yard vehicles, municipal sites pairing solar with standby power, and industrial roofs big enough to make generation pencil — commercial, industrial, and public projects across Arizona.

  • Offices and workplace charging
  • Industrial and warehouse rooftops
  • Municipal and public facilities
  • Fleet yards and parking structures
  • Mixed-use development

Engineering + CR-11 Crews

Engineered here. Installed by our own electricians.

Our in-house engineers design the system and our CR-11 electrical crews (ROC #276948) build it — same company, same project manager. The single-line that goes to TEP or Trico is drawn by people who will stand in front of the gear at energization, so the design is constructable, the install matches the stamp, and there's one name on the whole thing.
