New Jersey’s solar property tax exemption keeps your local assessor from raising your property taxes when you install solar panels on your home. Under N.J.S.A. 54:4-3.113a, the added value a certified renewable energy system brings to your property is excluded from its assessed valuation, so your tax bill stays at its pre-solar level.1New Jersey State Library. New Jersey Code 54:4-3.113a – Exempting Certain Renewable Energy Systems From Real Property Taxation With property tax rates in New Jersey among the highest in the country, that exclusion can save a typical homeowner roughly $1,000 or more per year depending on system size and local rates. The state layers a sales tax exemption on top, so solar equipment purchases are also free of the 6.625% sales tax.
How the Exemption Reduces Your Assessment
The mechanic is simple. Your municipal assessor calculates what the property would be worth without the solar system and what it is worth with the system installed. The difference between those two numbers is excluded from your taxable assessment. In the statute’s own language, the exempt amount equals the assessed valuation with the system minus the assessed valuation without it.1New Jersey State Library. New Jersey Code 54:4-3.113a – Exempting Certain Renewable Energy Systems From Real Property Taxation
That matters more than it sounds. Solar panels routinely add $15,000 to $30,000 in market value to a home. Without the exemption, that increase would flow straight into your assessed value, and at an effective property tax rate around 2.3%, you would owe several hundred dollars more each year for the privilege of generating your own electricity. The exemption removes that penalty entirely.
What Qualifies as a Renewable Energy System
The statute defines a renewable energy system as equipment that is part of or added to a building as an accessory use and produces renewable energy onsite. The system has to provide all or a portion of the building’s electrical, heating, cooling, or general energy needs.2Justia Law. New Jersey Revised Statutes Section 54:4-3.113a Rooftop solar panels, ground-mounted photovoltaic arrays, and solar thermal systems that heat water or air all qualify. The exemption covers residential, commercial, industrial, and mixed-use properties.
Battery storage is a gray area. The property tax exemption covers equipment that produces renewable energy, and a battery stores energy rather than producing it. The statute does not explicitly address home batteries. If you are adding a battery alongside solar, the panels themselves are clearly exempt, and the sales tax exemption discussed below does specifically cover energy storage devices, so at minimum you will not pay sales tax on the battery.
Getting Your System Certified
Before you can claim the exemption, your solar system must be certified by the local enforcing agency, which is the local construction office responsible for enforcing the Uniform Construction Code in your municipality.2Justia Law. New Jersey Revised Statutes Section 54:4-3.113a Certification sits with the Commissioner of Community Affairs, and the Department of Community Affairs has determined that the existing Uniform Construction Code requirements are enough to evaluate whether a system qualifies.3DSIRE.

In practice, that means the installation goes through the normal building and electrical permit process. Your installer pulls the permits, the local construction official inspects the completed work under the standard electrical and building subcodes, and once the system passes inspection it is certified. Most installers handle the permitting for you. Confirm that yours has obtained final inspection approval before you file with the assessor, because without that certification the assessor cannot approve the exemption.1New Jersey State Library.

Filing the Application With Your Assessor
Once the system is certified, you apply for the exemption through your municipal tax assessor. The New Jersey Division of Taxation provides Form CRES (Application for Certification of Renewable Energy System), available on the Division’s website or at the assessor’s office. The form asks for your property’s block and lot numbers from your most recent tax bill, your legal name as it appears on the deed, and technical details about the installation including system type, total wattage, and installation cost.
Have your contractor’s final invoice and the permit documentation on hand. The assessor needs enough information to calculate the difference in assessed value with and without the system.3DSIRE. Property Tax Exemption for Renewable Energy Systems
The exemption takes effect for the tax year after certification is granted.3DSIRE. Property Tax Exemption for Renewable Energy Systems If your system is certified and your application processed in 2026, the exemption shows up on your 2027 tax bill. File as soon as the system passes final inspection. Once granted, the exemption continues as long as the system remains operational; you do not need to refile every year.
Sales Tax Exemption on Solar Equipment
A separate statute exempts solar energy equipment from New Jersey’s sales and use tax. Any solar device or system designed to provide heating, cooling, or electrical power by collecting and transferring solar energy is fully exempt from the state’s 6.625% sales tax. The exemption explicitly extends to mechanical or chemical devices that store solar-generated energy, so batteries purchased alongside a solar installation qualify.4Justia Law. New Jersey Revised Statutes Section 54:32B-8.33 – Solar Energy Devices or Systems
On a $30,000 solar installation, the sales tax exemption alone saves roughly $2,000. Your installer should give you an Exempt Use Certificate (Form ST-4) documenting the tax-exempt purchase.5Legal Information Institute. New Jersey Administrative Code 18:24-26.4 – Procedure for Exemption Make sure the certificate lists the address where the system will be installed. If the installer tries to charge sales tax anyway, push back and cite the statute.
Leases and Power Purchase Agreements
Plenty of New Jersey homeowners do not buy their panels outright. Under a solar lease or power purchase agreement, a third-party company owns the equipment on your roof. That raises a fair question about who benefits from the property tax exemption.
The statute grants the exemption to “the owner of real property which is equipped with a certified renewable energy system.”1New Jersey State Library. New Jersey Code 54:4-3.113a – Exempting Certain Renewable Energy Systems From Real Property Taxation The focus is on the property owner, not the equipment owner. Because the exemption works by reducing the property’s assessed value, and property taxes are the property owner’s obligation, you are the one who benefits from the lower assessment regardless of who owns the panels. If you are in a lease or PPA and see a property tax increase you believe reflects the solar equipment, file for the exemption and take it up with your assessor.
Selling a Home With a Solar Exemption
The statute does not directly address whether the exemption transfers to a new owner when the home is sold. It attaches to the assessed valuation of the property rather than functioning as a personal credit to the original filer, which suggests it should carry over. Because the exemption is tied to a certified system, a new owner should confirm with the municipal assessor that it is still being applied after closing. If the assessor’s records do not reflect the exemption, submit a fresh application with documentation of the existing certified system.
Appealing a Denied Exemption
If your assessor denies the application or you believe the exemption was not properly reflected in your assessed value, you can file a property tax appeal. Appeals go to the County Board of Taxation on Form A-1.6NJ Division of Taxation. Assessment and Appeals
The standard filing deadline is April 1 of the current tax year. In municipalities undergoing a revaluation or reassessment, the deadline moves to May 1. Burlington, Gloucester, and Monmouth Counties follow an alternative calendar with a January 15 deadline.6NJ Division of Taxation. Assessment and Appeals These are firm. Paper filings must be physically received by 4:00 PM on the deadline date; a postmark alone will not save a late petition.
If your property’s total assessed value exceeds $1,000,000, you have the option of filing directly with the New Jersey Tax Court instead of the County Board. If the County Board rules against you, you have 45 days from the judgment to appeal to the Tax Court.6NJ Division of Taxation. Assessment and Appeals In either forum, the burden is on you to show the assessed value is unreasonable compared to fair market value. For a solar exemption dispute, that means demonstrating the assessor included the value of the renewable energy system in your assessment despite the statutory mandate to exclude it.
