Is Solar Worth It in Jamul in 2026?

For most Jamul homeowners planning to stay several years, yes — but the math changed substantially and batteries are now central to it. California's Net Billing Tariff, commonly called NEM 3.0, took effect April 15, 2023 and cut export credits roughly 75%, from near retail rates to avoided-cost rates averaging around 5 to 8 cents per kWh. Because SDG&E has the highest residential rates of any major U.S. utility, every kilowatt-hour you consume yourself is worth far more than one you export — which is why storage matters. Reported payback estimates for solar-plus-battery in SDG&E territory generally fall in the 7 to 11 year range. One critical change: the 30% federal Residential Clean Energy Credit under Section 25D ended for expenditures made after December 31, 2025, so a homeowner buying with cash or a loan in 2026 cannot claim it. For sellers, the single most important distinction remains owned versus leased.

Here's what Jamul owners need to know.

Why Solar Math Is Different in San Diego

SDG&E has the highest residential electricity rates of any major utility in the continental United States — the bundled residential average sat near 46 cents per kWh in early 2026, and blended figures around 42 to 47 cents are commonly cited, against a national average closer to 17 cents.

That's the entire reason solar works here even after the policy change. Every kilowatt-hour your system covers is worth roughly two and a half times what it's worth nationally.

And Jamul households use more than most. Inland heat means real air conditioning load. Homes average around 2,856 square feet against a county average near 2,017. Well pumps draw significant power. Pools are common. Barns, shops, and outbuildings add load. Electric water heating in some homes.

High rates plus high usage is the combination that makes the numbers work.

What NEM 3.0 Actually Changed

The Net Billing Tariff took effect April 15, 2023 for customers of PG&E, SCE, and SDG&E.

The point people miss: NEM 3.0 didn't reduce the value of the solar you use. The energy you consume inside your home is still worth full retail — which at SDG&E rates is a lot. Only exported surplus lost value.

Which changes the design goal entirely. Under NEM 2.0 you sized a system to offset annual usage and let the grid act as your battery. Under NEM 3.0, exporting midday surplus at 5 to 8 cents and buying it back at evening peak rates is a losing trade. The value now comes from using your own production during expensive hours — which usually means storage.

On grandfathering: systems interconnected before the transition generally remain on their original net metering terms for a 20-year period. If you have an older system, that grandfathered status is a genuine asset — and reportedly, adding battery storage to an existing NEM 2.0 system typically doesn't affect it. Verify with SDG&E before making changes.

The Payback Picture

Reported estimates vary by source and assumption, so treat these as ranges rather than promises.

One modeling estimate for SDG&E territory puts a solar-plus-battery home's first-year bill offset at roughly $2,500 to $4,000, with simple payback around 7 to 11 years against an assumed installed net cost in the range of $18,000 to $24,000 for a 6 kW system plus battery before any SGIP rebate.

Every source that publishes these numbers is estimating. Your actual result depends on your usage pattern, system size, installed price, whether you add storage, and future rate trajectory. Get multiple real quotes and ask each installer to model both a conservative and an aggressive rate-increase scenario.

The 2026 Tax Credit Change — Read This Carefully

This is the development most homeowners don't know about, and it materially changes the arithmetic.

The 30% federal Residential Clean Energy Credit under Section 25D ended for expenditures made after December 31, 2025, under the One Big Beautiful Bill Act. A homeowner who buys solar in 2026 with cash or a loan cannot claim it.

A separate commercial credit under Section 48E can apply to leased and power purchase agreement systems — but the business that owns the system claims it, not the homeowner.

California's net billing rules and SGIP were not affected by this change.

What this means practically: anyone comparing a 2026 quote against payback figures published before 2026 is comparing against numbers that included a 30% credit no longer available to cash and loan purchasers. Ask your installer to show the math without it.

We are not tax advisors. Federal tax law is complex and changes; confirm your situation with a qualified CPA before making a decision on this basis.

What Still Helps

• SGIP — the Self-Generation Incentive Program provides battery storage rebates for SDG&E customers, with reported amounts varying widely by eligibility category
• California property tax exclusion for active solar energy systems — reported as available through 2027, meaning a qualifying system generally doesn't increase your assessed value. Verify current status with the San Diego County Assessor
• The rates themselves — SDG&E's high prices remain the strongest driver of solar value in the country

The Jamul-Specific Case for Storage

Beyond the economics, storage does something in Jamul that it doesn't do in a city.

Power outages are a normal part of life here. Wind events and Public Safety Power Shutoff conditions happen, and they can last more than a day.

On a well property, no power means no water. The pump needs electricity. Without backup, you have whatever is in the pressure tank — realistically a glass or two.

A battery changes that, though sizing matters enormously: a submersible pump pulls several times its running current at startup, and that surge is the number a system has to handle, not the running load. Have this specified by someone who knows well systems, not just solar.

And during a fire event, an outage coinciding with an evacuation or a defense scenario leaves an unbacked property with no pressurized water at exactly the wrong moment.

Which means in Jamul, the resilience argument for storage stands alongside the financial one — and for many buyers it's the more persuasive of the two.

Owned vs. Leased: The Distinction That Matters Most at Sale

This is where solar most affects a real estate transaction, and getting it wrong costs sellers deals.

Owned solar is an asset. It reduces the property's operating cost permanently, and buyers value that — particularly in SDG&E territory.

Leased or financed solar is a transaction item. The buyer typically must qualify for and assume the agreement, and the provider has its own process and timeline. When this surfaces in week three of a thirty-day escrow, it becomes a problem.

What sellers with leased systems should do:

1. Locate the full agreement and read it
2. Contact the provider early and understand the transfer process and timeline
3. Know the credit requirements a buyer would face
4. Understand any buyout option and its cost
5. Disclose it in your listing materials, not at the offer stage
6. Build the transfer timeline into your escrow expectations

The mistake we see repeatedly: a seller who describes their property as having "solar" without specifying ownership, and a buyer who assumes it conveys free and clear. That misunderstanding surfaces during escrow and damages trust at exactly the wrong moment.

Solar and Your Roof

A practical sequencing point.

If your roof has limited remaining life, address it before installing solar. Removing and reinstalling panels to replace a roof underneath them is a real expense that installers will quote separately.

And in Jamul there's a second consideration: a Class A fire-rated roof is the single most significant structural factor insurers look at in a fire zone. If you're going to be on the roof anyway, the roofing and solar decisions should be made together rather than sequentially.

Also worth confirming: how your installer will handle mounting penetrations, whether the array affects your roof warranty, and how the system interacts with defensible space and ember-resistant requirements. Verify with your local fire authority.

Off-Grid and Ground-Mount

Two Jamul-specific variations worth mentioning.

Ground-mount systems make sense on acreage where roof orientation is poor, where the roof is aging, or where you have the space and want optimal exposure. They cost more to install, require their own permitting, and consume usable land — but on a large parcel that's often an acceptable trade.

Genuine off-grid — sized to run the property without a utility connection — is a different project entirely, involving substantially more storage, generator backup, and careful load management. It's a real path in the outlying valleys where extending utility service is expensive, and it appeals to a specific buyer segment.

Either way, permitting matters. Confirm requirements with San Diego County Planning & Development Services before committing.

How Solar Affects Your Sale

If you own the system

Market it specifically. Not "has solar" — say the system size, whether there's battery storage, the year installed, the typical production, whether it's grandfathered under NEM 2.0, and what the current electric bills actually look like.

Provide documentation: system specifications, installation date, permits, interconnection agreement, warranty, monitoring data if available, and recent utility bills.

The NEM 2.0 point deserves emphasis. If your system is grandfathered on the older, more favorable terms, that's a transferable advantage worth stating plainly — most buyers won't know to ask.

If you lease

Disclose early, prepare the paperwork, and contact the provider before you list. Handled proactively it's manageable. Discovered late it's a problem.

Either way

Solar interacts with everything else on a Jamul property. It offsets a well pump's substantial draw. It supports outage resilience for water. It reduces the operating cost of a large inland home with air conditioning and a pool. Frame it as part of the property's system, not as a feature on a list.

Frequently Asked Questions

Is solar worth it in Jamul in 2026? For most homeowners staying several years, yes — driven by SDG&E's rates, the highest of any major U.S. utility. Reported payback for solar-plus-battery in SDG&E territory generally falls in the 7 to 11 year range. If you're selling within a year or two, the payback exceeds your ownership horizon and buyers won't pay full installed cost.

What is NEM 3.0? California's Net Billing Tariff, effective April 15, 2023 for PG&E, SCE, and SDG&E customers. It cut export credits roughly 75%, from near-retail rates to avoided-cost rates averaging around $0.05 to $0.08 per kWh. Power you consume yourself still carries full retail value.

Do I need a battery? Not required, but it changes the economics substantially. Under net billing, exported surplus earns little, so the value comes from using your own production during expensive evening hours — which requires storage. Reported paybacks for solar-plus-battery are shorter than for solar alone.

Is the federal tax credit still available? The 30% Residential Clean Energy Credit under Section 25D ended for expenditures made after December 31, 2025. A homeowner buying with cash or a loan in 2026 cannot claim it. A separate commercial credit can apply to leased and PPA systems, but the owning business claims it, not the homeowner. Confirm your situation with a CPA.

Is my older system grandfathered? Systems interconnected before the transition generally remain on their original net metering terms for a 20-year period. Adding battery storage to an existing NEM 2.0 system reportedly doesn't affect that status — verify with SDG&E before making changes.

Does solar increase my property taxes? California has provided an active solar energy system property tax exclusion, reported as available through 2027, meaning a qualifying system generally doesn't increase assessed value. Verify current status with the San Diego County Assessor.

Does solar add value when I sell? Owned systems reduce a property's permanent operating cost, which buyers value — particularly in SDG&E territory. Leased systems are a transaction item requiring buyer qualification and assumption rather than an asset that conveys.

What if my solar is leased? Locate the agreement, contact the provider early to understand the transfer process and timeline, know the buyer credit requirements and any buyout cost, and disclose it in your listing materials rather than at the offer stage.

Should I install solar before selling? Generally no if you're selling within a year — the payback exceeds your ownership horizon and buyers won't pay installed cost. For a longer hold, the case is much stronger.

Will a battery run my well pump during an outage? It can, but sizing is critical — a submersible pump draws several times its running current at startup, and that surge is what the system must handle. Have it specified by someone familiar with well systems.

Why We Ask About Solar Early

We call ourselves Knowledge Brokers, and solar is a place where a single unasked question can cost a seller their escrow.

The question is simple: owned or leased? But the number of transactions that get complicated in week three because nobody asked it in week one is remarkable.

Beyond that, what we bring: knowing that a grandfathered NEM 2.0 system is a transferable advantage most buyers don't know to ask about. Knowing that the federal credit change in 2026 means a seller's original payback math no longer reflects what a buyer faces. Knowing that on a well property, battery storage isn't just an energy decision — it's a water decision. Knowing that a leased system needs the provider contacted before listing, not after an offer. And knowing that "has solar" in a listing is a wasted sentence when the specifics are what actually sell.
