What we do

Solar built for every scale

The “ARC” in our name is the work we do — Agricultural, Residential, and Commercial solar and storage — modeled honestly and engineered to last.

Agricultural

Power irrigation, barns, and equipment with systems sized for working land — and capture the grants that make the math work. We chase USDA REAP funding that can cover up to half of project cost for eligible operations.

  • Ground-mount & pivot systems
  • USDA REAP grant guidance
  • ITC + accelerated depreciation

Residential

Lower your bill and lean on the grid less with solar plus battery storage designed for how California actually works today — self-consumption and load-shifting under NEM 3.0, with honest payback math, not inflated export savings.

  • Rooftop solar & battery storage
  • NEM 3.0 self-consumption design
  • Honest payback — no hype

Commercial

Turn a rising power bill into an owned asset. Between the 30% federal tax credit, 5-year depreciation, and demand-charge reduction, commercial solar pencils out stronger than most owners realize — and we show the conservative math.

  • Rooftop, carport & ground arrays
  • ITC + MACRS depreciation
  • Demand-charge reduction
Your land. Your light. Your asset.

Utility-scale solar & energy brokerage

We connect landowners with the developers, capital, and offtake relationships that turn idle acreage into long-term energy income — brokered by a team that knows the deals, from origination through close.

Land & origination

Land sourcing, lease structuring, and early-stage development support for landowners.

Offtake & PPAs

Matching generation with creditworthy buyers and power agreements.

Capital & M&A

Connecting projects with developers, investors, and acquirers.

Interconnection

Navigating queues, studies, and grid milestones to de-risk deals.

Who we are

The honest side of solar

ARC Solar Group designs, builds, and brokers solar and energy-storage projects across California and the West — for homeowners, businesses, agricultural operators, and landowners alike. We were founded on a simple frustration: too much of the solar industry sells on hype and inflated projections, then leaves customers holding the bill when the numbers don't hold up.

We do it differently. Every project starts with conservative, transparent financial modeling — real production estimates, honest rate assumptions, and a clear-eyed view of today's net-metering economics. From residential rooftops with battery storage to commercial and agricultural systems chasing federal tax credits and USDA REAP grants, all the way to utility-scale land and energy brokerage, we engineer for compliance and long-term performance. Our goal is the same at every scale: to turn your roof or your land into an asset you understand, trust, and own.

Mission

To help homeowners, businesses, and landowners take control of their energy — designing, building, and brokering solar and storage projects that pencil out honestly, perform for decades, and turn rooftops and acreage into long-term assets.

Vision

A West where every viable roof and parcel produces its own power — and where the people who own them are treated as partners in the energy economy, not just customers.

Why ARC Solar Group

Five commitments we stand behind

Every piece of our work ladders back to these five pillars — the reasons homeowners, operators, and landowners trust ARC with the numbers.

01

We model conservatively — and show our work

Realistic production, honest escalators, and clear sensitivity to time-of-use rates. The numbers in our proposals are numbers we stand behind.

02

Built for NEM 3.0 reality

California's rules changed the math. We design for self-consumption and storage — not yesterday's export economics — and tell you the truth about payback.

03

Engineering & compliance come first

Permitting, NEC 690, AB 2143 prevailing wage, Title 24 — handled correctly the first time. Compliance protects your timeline and your investment.

04

One partner, residential to utility-scale

A home adding a Powerwall, a farm chasing a USDA REAP grant, or a landowner with acreage a developer wants — we have the design, financing, and brokerage relationships to move all three.

05

We turn energy into an asset

Federal tax credits, accelerated depreciation, grant capital, and renewable energy certificate value — we help you capture the full financial picture, not just bill savings.
