What we do

Four trades, one license number

Solar and storage, general contracting, commercial systems, and the electrical work that ties it all together. Carrying all four means no handoffs between companies that have never met.

Residential solar + storage

Rooftop and ground-mount PV with battery backup

Grid-tied systems sized to how your household actually uses power, paired with storage so the production you generate at noon is still yours at 7 p.m.

  • Roof and ground-mount arrays
  • Battery backup and whole-home protection
  • Off-grid and hybrid systems
  • Retrofits and repairs on existing arrays

General contracting

Additions, ADUs, remodels and new construction

The builders side of the business — new construction, repairs, restorations and remodels, run by the same people who will later stand on the roof.

  • Room additions and whole-home remodels
  • Accessory dwelling units
  • Kitchens, baths, decks and structural work
  • Roofing coordinated with solar layout

Commercial solar

Business, agricultural and multi-unit systems

Larger arrays where the math is a line item on a P&L. We work through the load analysis, utility interconnection and permitting with your team.

  • Commercial rooftop and carport arrays
  • Agricultural and well-pump systems
  • Commercial storage and demand management
  • Utility interconnection and permitting

Electrical + EV

Service upgrades and EV charging

The unglamorous work that makes everything else possible — and the most common reason a solar or ADU project stalls.

  • Level 2 EV charger installation
  • Main panel and service upgrades
  • Sub-panels and dedicated circuits
  • Generator and transfer-switch integration

Why it matters

The handoff is where jobs go wrong

A typical solar job involves a sales company, a subcontracted installer, a subcontracted electrician, and a roofer nobody told about the array. Every one of those seams is a place for a schedule to slip and for responsibility to get vague.

We do the work in house. That is not a slogan — it is the specific reason we can take thousands of dollars out of a system's cost, because there is no chain of companies marking each other up on the way to your roof.

It also means that when something needs fixing three years from now, you call the same number.
