Is Commercial Solar Worth It in New Jersey?
Is Commercial Solar Worth It in New Jersey?
Are solar panels worth it in NJ for a commercial building? For many owners the answer is yes, and you can usually tell from four facts you already have on file: who owns the building, how big and how sound the roof is, what you spend on electricity, and whether your business has a tax bill worth offsetting. This guide walks through each one, then explains what drives payback in New Jersey and when it makes sense to replace the roof before solar goes on.
Four signs commercial solar fits your building
LandAir has reviewed commercial buildings across New Jersey since 1996, and the strongest projects tend to share the same four traits.
- You own the building. Owners decide what goes on the roof and keep the savings for the life of the system. Tenants can still benefit, but the lease has to allow it and the term has to make sense, so ownership keeps things simple.
- You have a flat commercial roof of roughly 10,000 square feet or more. A larger, open roof spreads design, permitting and interconnection work across more panels, which helps the economics. Smaller roofs can still work, especially when a carport or ground area adds space.
- Your electricity runs around $1,500 a month, or about $20,000 a year. Solar savings come from the power you no longer buy. A meaningful bill gives the system enough load to offset.
- Your business has a tax bill worth offsetting. Federal tax credits and depreciation carry real value only when the owner can use them. Your accountant can confirm your position.
If your building matches all four, solar is very likely worth a closer look. If it matches two or three, a short review of your bills and roof usually settles the question.
What drives commercial solar payback in New Jersey
People often ask how much do solar panels save a business. The answer depends on a handful of inputs, and each one can be measured for your site.
| Factor | Why it matters |
|---|---|
| Utility rates | New Jersey commercial electricity rates are among the higher ones in the region, so every kilowatt hour the system produces replaces power that would otherwise cost you at retail rates. |
| SuSI incentive | The state pays for each megawatt hour a qualifying system produces, which adds a second income stream on top of bill savings. |
| Federal credit timing | The federal investment tax credit depends on when construction begins and when the system is placed in service, so the schedule matters. |
| Roof condition | A roof that will need replacement soon adds future removal and reinstall cost, which belongs in the model from the start. |
| System cost | Installed cost per watt varies with system size and type. Our commercial solar ROI and payback guide shows how these inputs combine. |
Because these inputs differ from building to building, we model payback from your actual bills and roof rather than quoting a general number.
How SuSI and federal incentives fit together
New Jersey’s Successor Solar Incentive (SuSI) program supports new systems through the Administratively Determined Incentive (ADI). Under the BPU’s May 2026 order, non-residential net metered rooftop, carport and canopy systems under 1 MW dc earn $110 per megawatt hour for a 15-year term, and ground mount systems under 1 MW earn $90 per megawatt hour. Carports earn the same rate as rooftop systems.
At the federal level, the investment tax credit under Section 48E remains available for qualifying projects. For solar projects that begin construction after July 4, 2026, the system must be placed in service by December 31, 2027 to qualify. Bonus depreciation is available at the full rate under current federal law, although New Jersey is decoupled from it for the state Corporation Business Tax.
Our 2026 guide to New Jersey commercial solar incentives covers each program in more detail. Your tax advisor confirms how the credits and depreciation apply to your business.
When to re-roof before going solar
A commercial solar array is built to stay in place for decades, so it should sit on a roof that can match that life. Replacing the roof first is usually the better plan when:
- The roof is approaching the end of its expected life or its warranty.
- There are signs of ponding, membrane wear or repeated leak repairs.
- You already have a roof replacement in the capital plan.
Planning both projects together avoids paying later to remove and reinstall the array. We coordinate the roof work with your roofer or a roofing contractor so there is one plan for both projects. See our roof replacement and solar page for how that coordination works.
Owning the system: cash or bank financing
LandAir focuses on ownership. You can pay for the system directly or use a conventional New Jersey commercial bank loan, and in both cases your business owns the asset, keeps the bill savings and claims the incentives it qualifies for. We do not offer leases or power purchase agreements.
If you are weighing ownership against a third-party agreement offered elsewhere, our CapEx vs PPA comparison for New Jersey lays out the trade-offs side by side.

Frequently asked questions
Is solar worth it in NJ for a business that leases its building?
It can be, but it depends on the lease. The tenant needs the right to install on the roof and enough remaining term to benefit. In many cases the building owner is in a better position to invest, and owners and tenants can agree on how the savings are shared.
How big does my roof need to be for commercial solar?
A flat roof of roughly 10,000 square feet or more is a strong starting point. Smaller roofs can still work, especially if a solar carport over parking or a ground area adds space.
How much do solar panels save a commercial building in New Jersey?
Savings depend on your electricity use, utility rates, system size, incentives and roof condition. We calculate them from your actual bills in a free Savings Snapshot rather than quoting a general figure.
Should I replace my roof before installing solar?
If the roof is near the end of its life or already in your capital plan, replacing it first is usually the better plan. We coordinate with your roofer or a roofing contractor so both projects follow one plan.
