Commercial Solar EPC Contractor in New Jersey
LandAir Energy is a New Jersey commercial solar contractor and EPC: engineering, permitting and construction under one company, not just a design on paper.
That means PE-stamped structural and electrical drawings, PSE&G or JCP&L interconnection paperwork, and a crew that builds what got approved. We manage the full sequence from signed contract to an inspected, energized system.

What a Commercial Solar EPC Actually Does
EPC stands for engineering, procurement and construction. When you hire LandAir as your solar contractor, one company designs your system, buys the equipment, builds it and stands behind the result. Commercial solar is a construction project first and an energy project second, so when the engineer, the buyer and the installation crew all work for the same firm, every detail stays inside one contract and you have one phone number for every question.
Our licensed Professional Engineers stamp the structural and electrical drawings, our NABCEP certified crews build what was approved, and our project team carries the job through inspection, utility witness testing and permission to operate. On occupied commercial buildings, with tenants, loading docks and production schedules to work around, that direct control of the crew keeps your operations running smoothly.
- Lower Energy Costs
- Increase Property Value
- Environmentally Friendly
- Energy Independence
Occupied Buildings Are Our Specialty
Most of our clients keep their buildings open during a solar project, so as your solar contractor we build around your operations. Rooftop work is sequenced zone by zone, electrical cutovers are scheduled on weekends or off shifts, and critical facilities can be connected with zero-outage tie-in methods. Staging, deliveries and crane lifts are planned with your team so tenants, staff and customers carry on as usual.
That construction discipline comes from building in New Jersey since 1996, with 400+ projects completed. One South Jersey manufacturer we built for eliminated 93% of its electric bill. See more numbers on our project results page.
- Electric bill review and usage pattern check
- Roof and site constraint review including access and safety
- Preliminary layout and sizing assumptions you can validate
- Early notes on permitting and interconnection requirements
- Clear next steps for design, pricing, and timelines
What Installation Costs, and How Incentives Cut It
Most New Jersey commercial rooftop systems land between $1.95 and $3.50 per watt installed in 2026 before incentives, with the 30% federal tax credit, SuSI and depreciation reducing the net cost substantially. Pricing depends on your roof, electrical service and system size. For full 2026 ranges, a sample building and a worked payback example, see our commercial solar cost and ROI guide, and every current program is covered in the NJ commercial solar incentives guide for 2026.
What we typically review (eligibility and amounts vary):
Cost coverage:
The 30% federal tax credit, depreciation and SuSI income combine to reduce net cost; we model what applies to your building.
Tax credits:
Federal credits may reduce net cost; we help document requirements for your accountant.
NJ incentives:
Production-based programs can add ongoing value tied to energy output; availability depends on program status.
Payback modeling:
We run conservative ROI scenarios using your rates, available area, and load profile.
Our Process
Step 1: Share your bill and site details
Step 2: Design, incentives, and approvals plan
Step 3: Build, turn-on, and reporting
What’s Included in EPC & Construction
Full equipment procurement and management
Modules, inverters, racking, monitoring, balance-of-system components. Tier-1 brands only: Q CELLS, REC, Silfab modules; SolarEdge, SMA, Enphase inverters; IronRidge, PanelClaw, RBI Solar racking.
Site mobilization and zone-by-zone install
Sequenced construction across roof zones so operations continue underneath active work. Daily cleanup and tool inventory. Single ground-floor staging area to keep the footprint small.
Roof penetration sealing per manufacturer spec
Coordinated with your roof manufacturer (GAF, Carlisle, Firestone, JM) to maintain warranty. Photo-documentation of every penetration before, during, and after sealing.
AC tie-in and electrical commissioning
Scheduled for weekend or off-shift window to minimize disruption. Critical-power facilities get parallel transformer tie-in with zero outage. Full commissioning verification before energization.
Utility witness test coordination
PSE&G, JCP&L, ACE, or Rockland witness test scheduled and managed. Anti-islanding verified, production tested, meter installed. Permission to Operate (PTO) documented.
Project documentation and handover
Complete as-built drawings, equipment data sheets, manufacturer warranties, monitoring portal access, and facility team handover meeting. Liquidated damages on contractor-caused schedule slips.

Frequently Asked Questions
What are the stages of a commercial solar installation?
As your solar contractor we run the whole sequence: bill and site review, engineering with PE-stamped drawings, permits and the utility interconnection application, construction, inspection, and finally the utility witness test and permission to operate. Utility interconnection review is usually the longest stage, so we file it early.
Will I lose production time during commercial solar installation?
In most cases, no. We sequence rooftop work so operations underneath carry on. The only brief interruption is the AC tie-in, which we schedule for a weekend or off-shift window, and critical facilities can use a zero-outage tie-in.
What happens if construction takes longer than expected?
Our standard EPC contract includes liquidated damages for schedule delays caused by us (not by weather, utility, or owner-caused delays). We provide a written project schedule at kickoff and weekly progress reports with photos.
Do you handle critical-power facilities like hospitals and data centers?
Yes. Critical-power facilities get parallel transformer tie-in engineering with zero outage during the AC connection. This adds upfront engineering cost but is non-negotiable for facilities where downtime has real consequences.
What does a commercial solar EPC contractor do?
EPC stands for engineering, procurement and construction. One contractor designs the system, buys the equipment, manages permits and utility approvals, builds it and commissions it, so you have a single point of responsibility.
Do you build battery storage as well as solar?
Yes. We are also a battery storage construction contractor, so solar and storage can be engineered and built as one project.
