How to Calculate the Added Value of Solar When You Sell Your Home

When selling a home with solar panels in New Jersey, one of the most important questions is: How much is the solar system worth to a buyer today? The value is not simply what the system originally cost — it’s based on the remaining financial benefits the system will produce.

Important: Only owned solar systems increase home value. Leased or third-party owned systems do not, but they may reduce energy costs during the lease.

Most solar systems provide economic value, but ownership matters:

Owned/Purchased Systems:

    • Energy Savings – Reduced electric bills over the remaining life of the system.
    • State Incentives – Remaining income from SRECs, TRECs, or SREC-II (ADI) payments, depending on the program the system qualified for.

Leased/PPA Systems:

    • Energy Savings vs. Lease Costs – Savings are calculated as projected energy production minus total remaining lease or PPA payments.
    • No Incentive Value – SRECs and other state incentives belong to the third-party owner and do not increase the home's resale value.

To determine the added value of solar at resale:

    • For owned systems: Calculate the Net Present Value (NPV) of remaining incentive payments and projected future utility bill savings.
    • For leased systems: Calculate the NPV of projected energy savings minus remaining lease/PPA costs over the remainder of the system’s service life.

NPV adjusts future cash flows into today’s dollars using a reasonable discount rate. This gives buyers, sellers, appraisers, and real estate professionals a financially sound estimate of what the solar system is worth right now — not what it was worth when installed.

Because New Jersey solar programs vary by installation date and have different term lengths (10 or 15 years), and because electric rates continue to rise over time, an accurate valuation must account for:

    • The system’s Permission to Operate (PTO) date
    • The remaining years in the applicable incentive program (for owned systems)
    • Current SREC/TREC/ADI values (for owned systems)
    • Utility rate inflation
    • System degradation over time
    • Remaining lease or PPA costs (for leased systems)

Using these factors ensures that the solar system is valued based on its future income-producing potential for owned systems, or net financial impact for leased systems, which is what truly drives resale decisions in today’s market.

How to Calculate Solar Value When Selling Your Home

Selling a home with solar in New Jersey? The system’s value isn’t its original cost—it’s what the Net Present Value (NPV) of future financial benefits are worth to the buyer today.

Important: Only owned solar systems increase home value. Leased or third-party owned systems do not, but they may reduce energy costs during the lease.

Owned/Purchased Systems:

    • Energy Savings – Lower electric bills for the remaining system life.
    • State Incentives – Remaining SRECs, TRECs, or SREC-II (ADI) payments.

Leased/PPA Systems:

    • Energy Savings vs. Lease Costs – Savings are net of remaining lease payments.
    • No Incentive Value – SRECs belong to the third-party owner.

Value is calculated using NPV to account for:

    • Remaining incentives (owned systems only)
    • Future energy savings
    • Utility rate inflation
    • System degradation
    • Remaining lease/PPA costs (leased systems)

This approach ensures accurate valuation for resale: future financial benefits for owned systems or net savings for leased systems.

I'll give them a 5 star rating for their work on this, as well as their solar panels business. Whether you have solar panels or not, consider giving Green Sun a chance to do your next soft wash project on your property. It worked out great for me and I highly recommend Green Sun.

If you are thinking about “going solar,” or even just getting a standby generator, you really ought to give Glen at Green Sun a call. "- Wayne from Middletown, NJ.  Solar Panel InstallationI recently contacted Green Sun ("GS")about power washing my house, deck, walkways, retaining walls, etc. GS obtained a detailed and up-to-date view of my property, and, along with the square footage of my home, developed a cost estimate. I obtained an estimate from another contractor, which was based on the same information as the GS estimate. GS was less expensive by a not-insignificant amount; yet, as best as I could determine, GS offered the same thorough approach using similar products as their competitor. I moved forward with GS. The 2-person team arrived on time on the scheduled day, and worked the full day, power washing all the walkways, deck, patio, retaining walls. I was scheduled for 2 days, and the team returned as scheduled and completed the job, including the roof and the rest of the house. The results were excellent- what a difference! The team quite obviously cared about what they were doing. A concern I had was the impact the power washing might have on the mature landscaping surrounding the treated areas. I was assured that as a matter of course, the team waters down the plants, trees, etc., before and after treatment. I need not have been concerned - no issues there. When it's time (again), I will definitely be using Green Sun for power washing. - Google
