Commercial solar. Three-phase ready.

Roof-mount and ground-mount commercial PV arrays. Three-phase string and central inverters, utility interconnect coordination, ITC documentation for your CPA, and post-install commissioning. We handle the electrical scope; we coordinate with structural and PV-module suppliers.

Service Overview

A commercial install is not a bigger residential.

Commercial solar runs on three-phase power. The inverters are different. The interconnect paperwork is different. The structural review is different. The federal Investment Tax Credit documentation your CPA needs is different. And the timeline is different — from quote to operation is typically 4-8 months, not 6-12 weeks.

We handle the electrical scope on commercial PV: three-phase inverter selection and sizing (SMA Sunny Tripower, SolarEdge Three-Phase, Fronius Symo, or central inverter for utility-scale), interconnect equipment (production meter, disconnect, current transformers), and the utility coordination with your TVA-LPC distributor.

We coordinate with the structural engineer on roof-load calculations and with your PV module supplier on racking and array layout. For ground-mount installs, we design the trench routing and DC home runs alongside the civil contractor on site.

For businesses pursuing the federal ITC and bonus depreciation, we provide the documentation package your CPA needs: itemized labor and materials by category, manufacturer warranty documents, commissioning data, and the cost-segregation breakdown that ties into your depreciation schedule. Most commercial installs cash-flow positive in year 5-7 once tax treatment is factored.

What’s Included

Commercial PV capabilities.

Three-phase inverter sizing

SMA Sunny Tripower, SolarEdge Three-Phase, Fronius Symo for distributed installs. Central inverter (SMA Sunny Central, Power Electronics, etc.) for utility-scale ground-mounts.

Structural coordination

We work with your structural engineer on roof load calcs, ballasted vs penetrated racking, and column-load distribution for ground-mounts. Roof reinforcement quoted separately when required.

Utility interconnect

TVA-LPC commercial interconnect studies, production metering, point-of-interconnection coordination. Larger installs require system impact studies; we manage that timeline with the utility.

ITC + bonus depreciation documentation

Federal Investment Tax Credit (30 percent + adders) documentation package for your CPA. Cost segregation, in-service date documentation, MACRS depreciation schedule support.

Battery and microgrid integration

Commercial battery storage (Tesla Megapack, Generac PWRcell Commercial, Enphase IQ Battery banks) for peak shaving, demand reduction, or backup. Microgrid controls integration when in scope.

Commissioning + handoff

Full commissioning report with megger readings, insulation resistance, ground continuity, inverter parameter logs. Operations and maintenance manual delivered at project close.

Same-day truck rolls across the East Tennessee corridor. Sevier, Knox, Blount, Jefferson, and Cocke counties primarily.

How We Run This Job

Five steps. No surprise invoices.

Step 01

Text or call us first

Describe the job. We follow up with a phone chat to scope it, then we send your quote. Same-day for most residential.

Step 02

On-site walk-through

For larger jobs, we come out, look at the panel, and talk through what you actually want. Free. No “let me get back to you.”

Step 03

Itemized estimate

Every line item priced. Materials, labor, permit, inspection. You see exactly where the dollars go before you sign anything.

Step 04

Job day · permits handled

We pull permits, coordinate with the county inspector, and arrive when we said we would. We protect your floors. We label every breaker. We test every circuit before we leave.

Step 05

Inspection & sign-off

Inspector signs off, we walk you through what changed, we hand over the documentation. If anything ever flickers, you have our cell.

Commercial solar array installation in Tennessee

We installed 180kW on our warehouse roof. Volt Pro ran the electrical scope, coordinated with our structural engineer and the utility, and gave our CPA exactly the cost-segregation breakdown she needed for the depreciation schedule. Operational on schedule. ITC paperwork was clean.

Common Questions

Five things we get asked every week.

What size commercial solar systems do you install?
From 30kW small business up to 500kW+ commercial and light industrial. Above that we coordinate with utility-scale developers as the electrical sub. Three-phase string inverters typically up to 250kW; central inverters above that.
How long is the commercial solar timeline?
4-8 months from contract to operation is typical. The long pole is utility interconnect — TVA-LPC commercial interconnect studies, system impact analysis, and commissioning scheduling all run in series. On-site electrical work is 1-2 weeks for most distributed commercial installs.
Do you provide ITC documentation for our CPA?
Yes. Federal ITC (30 percent + applicable adders for domestic content, energy communities, low-income), bonus depreciation under IRC 168(k), and MACRS 5-year depreciation all need specific documentation. We deliver a project close-out package built for your tax advisor.
Can you handle prevailing wage on public-sector commercial solar?
Yes. Davis-Bacon prevailing wage, certified payroll, and the close-out documentation required for city, county, state, and federal public-sector commercial PV are all part of our standard commercial workflow.
Do you do commercial battery storage?
Yes. Tesla Megapack, Generac PWRcell Commercial, Enphase IQ Battery banks. Most common use cases: peak shaving (reduce demand charges), Time-of-Use arbitrage where TVA rate structures support it, and backup power. We size battery against your interval data.
