If you’ve been tracking the solar panel installation tax credit situation through 2025 and into 2026, you’ve probably noticed the headlines aren’t as clean as they used to be. The federal rules that governed residential solar incentives changed under 2025 legislation, and a lot of the information still circulating online reads like it was written three years ago. I’m Ken Crotz, Jr., founder of Rooftops Energy Solutions, and my team of Master Certified installers has been putting solar panels and roofs on Treasure Valley homes for 12 years, serving 500 clients across the region. Every week I talk to homeowners in Boise, Meridian, Nampa, Eagle, and Caldwell who’ve seen a headline about getting a big percentage back from the federal government and want to know if it’s still real. The honest answer is: it depends on when your system goes in the ground — and the Idaho-specific incentives that most national guides never mention are still very much alive. Here’s what’s actually left.
Here’s the straight answer for 2026: the federal solar tax credit picture has shifted, and the placed-in-service date on your system now decides what you can claim. But for Treasure Valley homeowners, the Idaho Residential Alternative Energy Tax Deduction and Idaho Power net-metering still apply — and together they can make going solar pencil out. Below we lay out exactly what remains so you can decide before the landscape moves again.
Is the federal solar panel installation tax credit still available in 2026?
The short answer: it exists, but the rules governing it changed in 2025, and the credit percentage available to a homeowner this year is not the same blanket figure that applied in prior years. The IRS Residential Clean Energy Credit guidance is the authoritative source — and the specific amount you can claim turns on one critical variable: your system’s placed-in-service date.
The placed-in-service date is the date your photovoltaic (PV) system is installed, inspected, and operational — not the date you sign a contract, put down a deposit, or even the date panels arrive on your driveway. Only when the system is live and ready to generate power does it legally count for credit purposes. That distinction matters enormously if you’re debating whether to move forward this year or wait.
The Residential Clean Energy Credit is a nonrefundable federal income tax credit, meaning it reduces what you owe the IRS dollar for dollar. If the credit exceeds your tax liability in a given year, the unused portion can typically carry forward to future tax years — a provision that matters for homeowners whose annual tax bill is modest relative to system cost.
My honest advice: don’t anchor your decision to a percentage you read in a 2023 article. The credit your system qualifies for depends on when it’s placed in service, how 2025 legislation adjusted the schedule, and your personal tax situation. We walk through this with every client at the estimate stage — not to sell you on solar, but so you actually know the numbers before you commit.
What changed for homeowners going solar this year
The legislative shift to understand is the One Big Beautiful Bill Act, passed in 2025, which materially altered the federal clean energy credit landscape. Without getting into congressional procedure, the practical effect for residential solar buyers is that the phasedown schedule for the Residential Clean Energy Credit moved faster than the original Inflation Reduction Act had set out. The comfortable plateau that homeowners were counting on through 2032 no longer applies in the same form.
What this means for you: the placed-in-service date is more consequential than ever. A system completed and operational before a legislative cliff applies to your installation year is governed by different rules than one that slips into the following calendar year. If you’re mid-consideration, the timing of when you actually finish and activate the job — not when you start it — is the date that goes on your IRS Form 5695.
This is exactly why we give it to you straight at the estimate rather than leading with the biggest headline percentage we can find. The right answer for your household depends on your install timeline, your tax situation, and what current IRS guidance says for your placed-in-service year. What we can tell you with certainty is that the Idaho-specific incentive layer — the state deduction and Idaho Power’s net-metering program — didn’t disappear with federal legislation, and those still stack on top of whatever federal benefit applies to your situation.
Does Idaho have a state solar tax deduction?
Yes — and this is the layer that most national solar guides miss entirely when they write about Idaho homeowners. The Idaho Residential Alternative Energy Tax Deduction allows qualifying homeowners to deduct a portion of the cost of an approved alternative energy system, including solar photovoltaic systems, from their Idaho state taxable income. Unlike a tax credit, which reduces what you owe dollar for dollar, a deduction reduces the income that’s subject to tax — so its dollar value depends on your Idaho marginal tax rate.
The deduction structure spreads the benefit across multiple years rather than front-loading it all in year one, which means Treasure Valley homeowners see a multi-year reduction in state income tax after going solar. The specific percentages and annual caps are set by Idaho statute and can change, which is why I always recommend verifying the current terms directly with the Idaho State Tax Commission before making final decisions. The program exists, it’s been in place for years, and it meaningfully adds to the total solar panel installation incentives picture for owner-occupant homeowners across Idaho.
If you’re comparing solar economics for a home in Meridian roofing and solar, Nampa solar and roofing, or Caldwell solar installation, the state deduction applies region-wide across the Treasure Valley — it’s not city-specific. What varies by city is your utility relationship, your roof pitch and sun exposure, and your system sizing needs.
Idaho Power net metering and utility solar incentives that still apply
Beyond the federal and state tax picture, the ongoing economic engine for residential solar in the Treasure Valley is Idaho Power’s net-metering program, also referred to as on-site generation. When your solar panels produce more electricity than your home uses — which happens frequently on long Idaho summer days — the excess goes back into the grid, and Idaho Power credits your account for that generation. Those credits offset future utility charges during lower-production months or cloudy stretches.
Homeowners often search for a solar panel installation rebate from their utility when they start researching. What Idaho Power offers operates more like an ongoing billing credit than a one-time rebate: your meter tracks what you export, and those kilowatt-hours reduce future bills. For homes pursuing Eagle solar-plus-roof projects or Boise solar installation, where significant air-conditioning loads run through the long summer, a well-sized system can effectively zero out summer bills and bank meaningful credits for fall and winter.
Idaho Power also has interconnection requirements that govern how your system physically connects to the grid — permitting, metering, and utility approval are part of every installation we complete. The specifics of the net-metering credit rate, any program caps, and interconnection timelines are worth confirming directly with Idaho Power at the time you’re planning your install, since utility program terms can be updated. We stay current on these because program details affect the system sizing recommendations we make at the estimate.
One note for homeowners in communities served by utilities other than Idaho Power: verify your utility’s net-metering terms separately, as not all Idaho utilities structure their on-site generation programs identically.
How much can a Treasure Valley homeowner actually save on solar in 2026?
Rather than giving you a number pulled from a national calculator that doesn’t account for Idaho specifics, let me walk through the stacking logic honestly.
A typical Treasure Valley home — a 2,000 to 2,500 square foot house in Meridian or Nampa running central air and an electric water heater — might need an 8 to 12 kilowatt (kW) photovoltaic system to substantially offset its annual electricity use. System costs vary by panel brand, inverter type, roof configuration, and permitting, but the general residential solar market has become more competitive on pricing even as incentive structures evolved. We give homeowners a written estimate reflecting actual current system and labor costs — not a ballpark from a national website.
The full stack of solar panel installation incentives available to an Idaho owner-occupant in 2026 looks like this:
- Federal Residential Clean Energy Credit: A percentage of your system’s qualified cost applied to your federal tax liability, with carryforward provisions if your credit exceeds your liability in year one. The exact rate for your placed-in-service year requires verifying against current IRS guidance — we do this at the estimate, for your install timeline.
- Idaho Residential Alternative Energy Tax Deduction: A multi-year reduction in your Idaho state taxable income. Value depends on your state marginal rate and the deduction schedule in effect when you install.
- Idaho Power net metering: Ongoing monthly bill offsets from credits for exported generation — the value of this compounds every year your system is operating, and it continues indefinitely as long as the program is in place.
Payback periods — the point at which cumulative savings equal your net system cost after incentives — tend to run somewhere in the range of 7 to 12 years for well-sized Treasure Valley residential systems, depending on system size, current utility rates, how your household uses power, and how incentives apply to your specific situation. That’s a meaningful range, and the right number for your address is what a site-specific estimate produces.
After payback, the savings are essentially yours. Premium solar panels carry manufacturer performance warranties in the 25-year range, meaning a system sized and installed correctly in 2026 should still be producing meaningfully in the 2040s. That long runway is what makes the return-on-investment conversation worth having even as the federal credit has shifted.
For homeowners in Star roofing and solar or solar and roofing in Kuna, the economics are essentially the same as central Meridian — same utility, similar sun exposure, identical state incentive access. Location affects roof pitch, shading, and system orientation more than it affects the incentive stack.
Who qualifies — and do rental property owners qualify?
The Residential Clean Energy Credit, at the federal level, applies to owner-occupants who purchase a qualifying solar system for their primary or secondary residence. You need to own the home and the system. A solar lease arrangement — where a third-party company owns the panels and you pay for the electricity they produce — does not qualify the homeowner for the Residential Clean Energy Credit, because you don’t own the equipment. If you’re evaluating a solar lease versus a direct purchase, understand that this is one of the most significant financial differences between the two paths.
For rental property owners, the picture is different. The residential credit is explicitly for personal-use property; a rental you don’t occupy doesn’t qualify. However, investment property owners may be able to access business energy credit pathways under separate IRS rules, which apply to solar installations on commercial and income-producing properties. These involve different code sections, different requirements, and different limitations — involve your CPA early.
The short version: rental property solar can still be viable — reduced operating costs, potential depreciation benefits, and property value considerations all factor in — but the federal credit pathway is not the same as for owner-occupants. See all our roofing and solar services for an overview of how we handle both residential and commercial project types.
Should you replace your roof before installing solar panels?
This is one of the most important questions I ask every prospective solar client, and it’s one that a solar-only company has a financial incentive not to raise at all. We’re both a Master Certified roofing contractor and a solar installer — which means we can give you the straight answer.
If your asphalt shingle roof is 15 to 25 years old, the honest calculus almost always favors replacing it before mounting a solar array. Solar panels are designed to last 25 years or more. When we mount them to a roof that has 5 to 7 years of life left, you’re setting yourself up to pay a detach-and-reset cost in the not-too-distant future. Removing a full array, reroofing the house, and then reinstalling and reconnecting the panels adds labor and logistics cost that can meaningfully erode your payback math. Doing it right the first time — a new residential roof replacement followed immediately by solar — eliminates that future cost entirely.
Treasure Valley winters are real. Nampa, Caldwell, and Meridian see significant snow loading in heavy years, and at higher elevations toward McCall or across the high desert, freeze-thaw cycles and ice loading stress roofing systems hard. A roof at end of life under a solar array is both a performance risk and a warranty complication. Our solar panels and systems are mounted on roofs we stand behind — literally — with a 40-year manufacturer warranty on roofing materials and a 10-year workmanship warranty on our labor.
When we come out for a free estimate, we assess roof condition as part of the evaluation. If we see a roof that has enough life to safely support a 25-year solar investment, we’ll tell you. If the roof needs replacing first, we tell you that too — and we’ll give you a combined project cost so you can see the full picture before deciding. That’s the no-upsell, straight-talk approach our clients describe, and it’s how we’ve built 500 client relationships over 12 years.
For homeowners in Middleton service area, Wilder service area, or Marsing roofing and solar, we make the same drive out and give the same honest evaluation — roof age and condition are universal factors regardless of which Treasure Valley community you’re in.
How to decide right now: four tests before you sign
If you’re mid-consideration on solar in 2026, here’s the decision framework I’d walk any honest neighbor through.
1. The incentive-timing test
What federal credit applies to your install year, based on when your system will actually be placed in service — not when you sign a contract? What does the Idaho state deduction add on top? What is Idaho Power’s current net-metering credit structure? These three numbers, for your specific household and install timeline, determine whether the economics work. Don’t sign based on a headline percentage from a prior year. Get a written estimate that shows incentive-adjusted net cost for your placed-in-service date.
2. The roof-condition-first test
How old is your roof, and does it have enough remaining life to outlast a solar system? If you’re on a 20-year-old shingle roof, the detach-and-reset cost you’ll face in a decade can materially change the payback math. A combined roofer-installer evaluates both at one visit. We do this at no charge.
3. The total-value-over-lowest-bid test
Solar quotes vary not just in price but in panel quality, inverter type, warranty coverage, and installer credentials. Louis M., one of our clients, compared three quotes and chose our TOPS package with water and ice shield — not because we were the cheapest, but because of what the package covered. Brian D. put it plainly: “Even if the bid is slightly higher than the competition I would recommend you choose this class team.” Installer certification matters: we’re Master Certified, factory-trained, licensed, insured, bonded, and Idaho-registered.
4. The warranty-and-workmanship test
Before you sign anything, confirm in writing: what warranty covers the materials, and what warranty covers the labor? We back roofing materials with a 40-year manufacturer warranty and our workmanship with a 10-year warranty. On repair work, we stand behind it with a 2-year warranty. Ask every installer you compare against for their warranty documentation in writing — it’s one of the most consequential factors in a 25-year investment decision.
How to claim your federal and Idaho solar benefits together
The sequencing for claiming your available benefits works like this:
Step 1 — Federal credit via IRS Form 5695. After your system is placed in service, your tax professional files IRS Form 5695 (Residential Energy Credits) with your federal return for that tax year. The credit calculated on Form 5695 reduces your federal income tax liability. If the credit exceeds your liability in year one, the remainder carries forward to subsequent tax years until it’s fully used.
Step 2 — Idaho state deduction. For the Idaho Residential Alternative Energy Tax Deduction, the deduction is claimed on your Idaho state return in the year of installation and continues in subsequent years according to the deduction schedule. Verify the current deduction amounts and any income considerations directly with the Idaho State Tax Commission or your tax advisor before filing — statutory terms are subject to change.
Step 3 — Idaho Power net-metering enrollment. Net metering isn’t a tax form — it’s a utility program you’re enrolled in as part of the interconnection process. Once your system is live and interconnected, the credit mechanism runs automatically on your monthly bill going forward.
At the estimate stage, we walk through what documentation you’ll receive from us — itemized system costs, installation records, placed-in-service confirmation — that your tax professional will need to file Form 5695 and the Idaho state deduction correctly. We’re not your CPA, but after 12 years and 500 client projects, we know exactly what paperwork matters and we make sure you have it.
Why Treasure Valley homeowners get their straight numbers from Rooftops
I founded Rooftops Energy Solutions 12 years ago with one operating principle: tell homeowners the truth about what they’re buying. We’re a veteran-owned business, and the integrity-first culture that military service builds is the same one my team brings to every estimate and every job. We’ve served 500 clients across the Treasure Valley — from Boise solar installation to Eagle solar-plus-roof projects to Garden City roofing and solar to Parma service page — and our reviews reflect what that approach produces.
Mike S. said Ken “gave it to me straight without any upsell.” K D. met with Ken on Monday, had an estimate by Tuesday, and the job completed that Thursday. Suzi S. called about a leak and we were on-site that same day. Diana S. checked out a few places and chose us for the best price and professionalism. That’s how we operate — hands-on, communicative, and built around your timeline and your real needs, not our sales pipeline.
Our Master Certified, factory-trained installers are backed by credentials that matter for your long-term protection:
- 40-year manufacturer warranty on roofing materials
- 10-year workmanship warranty on labor
- 2-year warranty on repair work
- Licensed, insured, bonded, and Idaho-registered
The view from Rooftops is different — and so is the conversation you’ll have at a free estimate. We’re not going to lead with the biggest credit percentage we can find. We’re going to tell you what applies to your system, your roof, your install year, and your tax situation — and let you make the call with real numbers in front of you. No pressure, no upsell, no outdated headline figures.
