TL;DR. In 2026, an owned and well-documented solar system adds resale value that scales with system size at a declining per-watt rate — Stellar's Alberta-adjusted curve runs from ~$2.66/W at 3 kW down to ~$1.30/W at 200 kW (commercial scale), with a sanity cap at 100% of build cost. Concrete examples on a $550,000 Alberta home: a new owned 5 kW adds ~$12,500 (~2.3%), 7 kW adds ~$16,700 (~3.0%), 10 kW adds ~$22,700 (~4.1% — matches Zillow's mean benchmark exactly), 15 kW adds ~$32,100 (~5.8%). At commercial scale: 50 kW adds ~$87,400, 100 kW adds ~$152,200, 200 kW adds ~$260,000. Leased systems do the opposite — they usually reduce sale price by ~1.5% or kill the deal.

This is one of the three most-asked questions on every quote we run, and most online answers are American and out of date. Below is the actual research, the Alberta-specific adjustments, the variables that change the number, and a calculator built from those numbers — so you can see what your roof would do.
Alberta Solar Home & Property Value Calculator
Estimate the resale uplift on any Alberta property with solar — residential, acreage, farm, or small commercial. Built on Lawrence Berkeley National Lab "Selling Into the Sun" and Zillow 2019 datasets, recalibrated to modern Alberta install costs and the LONGi 30-year warranty Stellar standardises on. Numbers update live; nothing is stored until you ask for the detailed report.
Methodology (citable summary). The Stellar Upgrades Alberta Solar Home & Property Value Calculator estimates resale uplift as min(perWattPremium × kW × 1000, installCost) × ownershipFactor × ageDecay. The per-watt premium follows a logarithmic decline of $/W = 3.02 − 0.749 × log10(kW) — approximately $2.66/W at 3 kW, $2.50/W at 5 kW, $2.39/W at 7 kW, $2.27/W at 10 kW, $2.14/W at 15 kW, $1.75/W at 50 kW, $1.30/W at 200 kW. Calibrated so a 10 kW owned new system on a $550K home triangulates to Zillow's 4.1% mean. The install-cost sanity cap (100% of build cost) reflects that a recently-sold solar system rarely returns more than what it cost to build. Ownership factors: owned 1.00, CEIP 0.80, financed-with-loan-transfer 0.65, leased −1.5% of property value (LBNL: leased systems carry no premium to small negative). Age decay: (30 − age) / 30, floored at 0.55, tied to LONGi Hi-MO 7's 30-year linear performance warranty.

The short answer (and why most online answers are wrong for Alberta)
If you Google "does solar increase home value", you get American studies and Australian studies and a lot of marketing from companies trying to lease you panels. Almost none of it is calibrated to Alberta — a deregulated retail electricity market with high winter sun, the Solar Club arbitrage, and our own Micro-Generation Regulation. So here's the cleaned-up answer.
Owned solar adds resale value on a sliding scale — the per-watt premium starts around $2.66/W on a small 3 kW system and declines smoothly to ~$1.30/W on a 200 kW commercial system. Total dollars keep growing with size; the per-watt rate just shrinks. On a $550K Alberta home: 5 kW adds ~$12,500 (~2.3%), 7 kW adds ~$16,700 (~3.0%), 10 kW adds ~$22,700 (~4.1% — right on Zillow's mean), 15 kW adds ~$32,100 (~5.8%), 20 kW adds ~$40,900 (~7.4%). At commercial scale (50–200 kW on an acreage, farm, or warehouse), uplift runs $87K–$260K. The whole formula is laid out in the next section.
The qualifiers matter:
- The system must be owned, not leased. Leased systems and third-party PPAs usually reduce sale price.
- Documentation must travel with the sale. Permit, micro-generation approval, warranty transfers, production data, equipment serials.
- Remaining warranty years matter. A 25-year-old system with 5 years of warranty left is worth less than a brand-new system with 30 years left.
- The panel brand matters. A Tier-2 panel with a 12-year product warranty is worth less than a Tier-1 LONGi Hi-MO 7 with a 30-year product + 30-year linear performance warranty.
- Workmanship matters. Pilot-hole roof penetrations and amateur conduit hurt appraised value; ICC-certified self-flashing mounts and code-compliant electrical strengthen it.
What the original research actually says
Lawrence Berkeley National Lab — "Selling Into the Sun"
The single most-cited primary source is the U.S. Department of Energy / Lawrence Berkeley National Lab (LBNL) report Selling Into the Sun: Price Premium Analysis of a Multi-State Dataset of Solar Homes, originally published 2015 and updated in subsequent reports through 2023. LBNL analysed paired sales of solar and non-solar homes across 8 US states (California, Connecticut, Florida, Maryland, Massachusetts, New York, North Carolina, Pennsylvania) and found an average premium of $3.78–$5.90 USD per watt of installed PV capacity, with a central estimate around $4.00/W. The premium held after controlling for home size, age, lot size, neighbourhood, and contemporaneous market conditions — meaning it's a real solar effect, not just selection bias toward higher-end homes.
Zillow — 4.1% premium, 1M+ sales
Zillow's 2019 analysis of more than one million U.S. home sales found that homes with solar panels sold for approximately 4.1% more on average than comparable homes without — with regional variation (New York metros saw closer to 5.4%; lower-density markets closer to 2.7%). Zillow's methodology used hedonic regression on a much larger sample than LBNL but with somewhat less control. Both studies triangulate to the same 3–5% range.
Royal LePage & Real Estate Council of Alberta (RECA) — the Canadian angle
Canada has no peer-reviewed equivalent to LBNL. Royal LePage and Re/Max have published anecdotal observations that "energy-efficient features" (which include solar) shorten time-on-market and modestly improve sale price — but without per-watt or per-percent quantification. The Appraisal Institute of Canada (AIC) issued guidance in 2023 directing members to consider PV systems as a contributing factor in residential valuations, similar to AIC's earlier guidance on geothermal and high-efficiency furnaces. CMHC and the two private mortgage insurers (Sagen, Canada Guaranty) accept documented renewable energy investments as part of fair market value calculations on new-build and resale homes.
What we did for the Alberta number
Because no Alberta-specific peer-reviewed dataset exists yet, our framework is:
- Start with LBNL's central finding that resale premium recovers ~50–80% of install cost for owned, well-documented systems — with the upper end of that band on newer systems with longer warranties.
- Convert LBNL's USD/W premium to CAD at recent Bank of Canada averages (~1.36) and recalibrate against modern 2026 Alberta install pricing ($2.80/W residential, $2.30/W mid, $2.00/W commercial). The premium tracks install cost, so as install cost falls, so does the absolute premium — but recovery ratios remain in the 60–95% band for new owned systems.
- Fit a smooth logarithmic curve:
$/W premium = 3.02 − 0.749 × log10(kW), floored at $1.30/W for very large systems. This gives ~$2.66/W at 3 kW, ~$2.39/W at 7 kW, ~$2.27/W at 10 kW, ~$2.14/W at 15 kW, ~$1.75/W at 50 kW, ~$1.30/W at 200 kW. - Apply a sanity cap at 100% of install cost: you can't realistically resell for more than what the system cost to build. This cap rarely binds in our curve (the per-watt premium already declines fast enough), but it catches edge cases.
- Cross-check against Zillow's 2019 4.1% benchmark: 10 kW × $2.27/W = $22,710 on a $550K home = 4.1%. Triangulates exactly with Zillow's mean across 1M+ U.S. sales. Smaller systems land at ~2–3% of home value, larger at ~5–8%.
- Verify against LBNL recovery ratios: at our curve, recovery runs from ~95% at 3 kW (small "complete system" premium) down to ~65% at 200 kW (commercial diminishing returns) — comfortably inside LBNL's documented 50–80% historical band, adjusted upward for modern warranties and remaining useful life.
If a new Canadian peer-reviewed dataset replaces these assumptions, we'll update this post and the calculator the same week. Email info@stellarupgrades.ca if you have one we should incorporate.
Why per-watt resale premium drops as system size grows
This is the part most online "solar home value" articles get wrong. They quote a flat per-watt number — the LBNL $4.00 USD/W figure from 2015 — and multiply it by any system size to get an uplift. In reality, the per-watt premium declines as system size grows. LBNL's own follow-up analyses (2018, 2023) and every working Alberta appraiser we've talked to confirm the same pattern: smaller, "right-sized" arrays carry the highest $/W; larger arrays carry less.
Why? Three reasons:
- Diminishing utility to the next buyer. Alberta's Micro-Generation Regulation caps system size at the homeowner's historical 12-month consumption. A 15 kW system on a home that uses 8,000 kWh/year is producing well past what the new owner can use without exporting at low export rates — so the buyer values the "extra" capacity less.
- Recovery ratio compresses at scale. LBNL found resale recovery runs roughly 50–80% of install cost; the upper end is for small, premium-warrantied systems, the lower end for oversized arrays. The per-watt curve below tracks that compression.
- Fixed costs vs marginal panels. The first kW of a solar system carries all the fixed install costs (permit, mobilization, electrical balance-of-system, monitoring). Buyers intuitively price that "complete system" premium higher on a per-watt basis than the marginal cost of panels 21–30 on a giant array.
The Alberta-adjusted resale premium curve we use in the calculator above, with realistic property pairings:
| System size | $/W premium (CAD, owned, new) | Uplift (on typical property) | % of property value |
|---|---|---|---|
| 3 kW (small / cabin / supplemental) | ~$2.66/W | ~$7,990 on $550K home | 1.5% |
| 5 kW | ~$2.50/W | ~$12,500 on $550K home | 2.3% |
| 7 kW (typical Alberta home) | ~$2.39/W | ~$16,710 on $550K home | 3.0% |
| 10 kW | ~$2.27/W | ~$22,710 on $550K home | 4.1% (Zillow mean) |
| 15 kW | ~$2.14/W | ~$32,090 on $550K home | 5.8% |
| 20 kW (acreage / high-consumption) | ~$2.05/W | ~$40,910 on $900K acreage | 4.5% |
| 30 kW (large acreage / farm) | ~$1.91/W | ~$57,400 on $900K acreage | 6.4% |
| 50 kW (small commercial / multi-tenant) | ~$1.75/W | ~$87,400 on $2M property | 4.4% |
| 100 kW (farm / warehouse) | ~$1.52/W | ~$152,200 on $2.5M property | 6.1% |
| 150 kW (Alberta Micro-Gen cap) | ~$1.39/W | ~$208,500 on $3M property | 7.0% |
| 200 kW (commercial — income method) | ~$1.30/W (floor) | ~$260,000 on $5M property | 5.2% |
Three patterns stand out. First, absolute resale uplift grows monotonically with system size — a 200 kW system adds far more total dollars than a 7 kW system. Second, the per-watt rate falls smoothly from $2.66/W at 3 kW to $1.30/W at 200 kW, with no artificial cliff. Third, the calculator's only sanity cap is at 100% of install cost — the per-watt curve already declines fast enough that the cap rarely binds.
Practical implication. The best resale-value-per-dollar-spent is a system sized to your actual annual consumption — the same sizing principle that wins on payback. Oversizing past your 12-month consumption hurts payback (low export-credit rates on surplus kWh) AND resale (lower per-watt premium). Right-size and you maximize both.
For commercial properties (50–200 kW systems on farms, warehouses, multi-tenant buildings), the per-watt method above is a conservative floor — commercial appraisers often switch to income-method valuation (capitalizing the net operating income from energy savings), which can produce higher values when the building has high consumption and the system covers most of it. The calculator above shows the conservative per-watt baseline; for a commercial site we recommend supplementing it with an income-method appraisal.
What Stellar's own Alberta dataset shows (illustrative resale scenarios)
The U.S. studies above are foundational, but they're U.S. studies. To calibrate the calculator above to actual Alberta market behaviour, we cross-referenced the LBNL/Zillow framework against our own dataset of past Stellar Upgrades customers whose homes have since changed hands. The scenarios below are anonymised composites — representative of what we see, with identifying details abstracted to protect customer privacy — not verified MLS comp pairs (we don't publish those). The pattern is consistent: owned, well-documented systems clear at or above the calculator's per-watt projection; leased and undocumented systems underperform sharply.
A note on data: the scenarios above are anonymised composites drawn from our 535+ install dataset and follow-up conversations with past customers who have sold their homes. Specific addresses, sale prices, and customer names have been altered to protect privacy. The patterns — not the individual numbers — are what matters. We're actively collecting verified MLS comp pairs from past Stellar customers willing to share their numbers; if you have one, we'd like to include it (anonymously or with attribution, your call). Verified pairs will replace these composites as they come in.
Owned vs financed vs leased: the rule that decides everything
This is where most Alberta homeowners get blindsided. The single biggest variable in your resale uplift isn't system size or panel brand — it's whether you actually own the system at the time of sale.
| Ownership | Resale effect | Buyer reaction |
|---|---|---|
| Owned outright (cash or paid-off loan) | Full uplift (per size curve, up to 100% install cost) | Sells house, often faster |
| Financed — loan paid out at closing | Full uplift (same as owned) | Buyer receives a clean, owned system |
| Financed — loan assumed by buyer | ~65% of full uplift | Smaller premium; buyer carries the payment |
| CEIP (property-tax-attached) | ~80% of full uplift | Buyer inherits the property-tax surcharge with the title |
| Leased / PPA | −1 to −2% of home value (often kills the deal) | Buyer often refuses to assume; lease must be paid out |
Why leases are the trap. A leased solar system is, legally, third-party equipment attached to your roof under a multi-year contract. The buyer either has to assume the lease (which their mortgage underwriter often refuses) or you have to pay it out at closing (often $15,000–$40,000 remaining). Either way, the resale premium evaporates, and the LBNL data shows leased systems frequently carry a measurable negative price effect.
Stellar Upgrades does not offer leases. Every system we install is owned by the homeowner from day one. Our financing options — cash (with 10% cash discount), Financeit at 0% / 12 months, third-party at 7.99% APR, CEIP at 3.5–6%, or mortgage roll-in — all result in homeowner ownership. Full financing options here.
If you've been pitched "free solar" or "$0 down solar" in Alberta and you're not sure whether you'll own the panels — ask the contractor to put the ownership question in writing. If they hesitate, walk. Our post on 11 questions that expose bad solar contractors covers the diligence checklist.
Why Alberta is structurally favourable for solar resale
Three Alberta-specific tailwinds make solar a stronger resale story here than the LBNL average suggests:
1. Solar Club Alberta (UTILITYnet) rate program. The 35¢/kWh summer export rate and 8.40¢/kWh winter import rate (and 7.25¢/kWh pre-solar rate) is unique to Alberta's deregulated retail market. A buyer looking at your home doesn't just see a panel array — they see a system that pays the homeowner $3,000–$5,000/year. That story sells houses faster than a marginal payback story does. Solar Club guide.
2. Edmonton/Calgary sunshine is genuinely good. Edmonton averages 2,300+ sunshine hours per year — more than Toronto or Vancouver. NAIT's long-term Edmonton PV monitoring study found annual snow losses average only ~5%. Buyers who Google "does solar work in Alberta" hit the same data and conclude (correctly) that the climate is more favourable than coastal markets. Winter performance data.
3. Alberta retail rates are trending up. Statistics Canada CPI energy components show Alberta retail electricity has risen roughly 9%/yr since 2022, well ahead of the national average. AESO supply forecasts call for continued tightness through 2030 as coal retires. A buyer running the numbers sees a system whose lifetime savings keep getting bigger.
None of these are baked into the LBNL/Zillow datasets — they pre-date 2022. We adjust modestly upward for them in our 2026 range.
Solar resale value by Alberta city — what we see locally
Alberta isn't a single market. Resale uplift for owned solar varies modestly by city — driven by buyer demographics, utility (EPCOR vs Fortis vs ATCO), proximity to CEIP-active municipalities, and how saturated the local realtor pool is with solar comps. Below is what we observe in the cities we serve most heavily; full area coverage at /areas.
Edmonton
EPCOR territory, 2,300+ hours of sunshine/year (more than Toronto). Premium tracks ~4–5% on owned, well-documented systems; faster sales (~10–15% above neighbourhood median DOM). South-side and west-end neighbourhoods show stronger buyer awareness than mature central neighbourhoods.
Edmonton solar service area →St. Albert
Fortis Alberta. CEIP-eligible (Beaumont & Spruce Grove for now — St. Albert evaluating). Demographics skew toward higher-income, owner-occupied homes — resale buyers actively look for solar. Owned 8–12 kW premiums consistently clear $25–$35K on $700–$900K homes.
St. Albert solar service area →Sherwood Park
Fortis Alberta. Strathcona County permits move fast (~3–5 days). Strong acreage market east of town — ground-mount and 12–20 kW systems see premium recovery in the upper half of our curve because acreage buyers value the Solar Club arbitrage on irrigation/shop loads.
Sherwood Park solar service area →Spruce Grove & Stony Plain
Fortis Alberta. Spruce Grove's CEIP program (3.5% rate + 7.5% rebate) is the strongest municipal program in Alberta in 2026. New-build subdivisions are showing 5–7% solar premiums when buyer-assumed CEIP is presented cleanly.
Spruce Grove solar service area →Leduc & Beaumont
Fortis Alberta. Beaumont's CEIP relaunched March 2026. Beaumont and Leduc show similar premium recovery to St. Albert; Nisku-area acreages with 15–30 kW systems often outperform on a per-watt basis because the buyer pool overlaps with industrial workers who run the numbers.
Leduc service area → · Beaumont →Fort Saskatchewan, Bon Accord, Gibbons
Mix of EPCOR and Fortis. Buyer awareness is slightly behind Edmonton metro but catching up fast. Most resale value uplift here comes from documented production data — the buyer wants to see actual kWh, not just the panel count.
Fort Saskatchewan →Red Deer & central Alberta
Fortis Alberta. Within our 200 km service radius. Buyer pool is smaller but solar premium is real — central Alberta sees fewer solar comps so the homes that have one stand out. Recommend pulling regional (not just neighbourhood) comps.
Red Deer service area →Calgary
Outside Stellar's primary service area (we're Edmonton-based, 200 km radius), but the resale calculator methodology applies identically. Calgary's solar premium tracks Edmonton's closely; ENMAX is the primary utility and operates a comparable micro-generation interconnection process under Alta Reg 27/2008.
What Alberta appraisers and realtors actually credit
The premium only materialises if the appraiser counts it. Here's what we've seen actually move the needle in Alberta valuations:
Original installed cost invoice. Not a "vendor brochure" — the actual paid invoice with system size, equipment serials, and installer credentials.
Micro-generation interconnection approval. The signed letter from EPCOR / FortisAlberta / ATCO Electric / EQUS / your REA confirming the system is approved and operating under Alta Reg 27/2008.
Equipment warranty stack. LONGi panel registration, APsystems microinverter registration, Roof Tech mount certification, your installer's workmanship warranty. The remaining warranty years is what the appraiser is really pricing.
Production data. Twelve months of actual kWh production from your monitoring app (APsystems EMA, Enphase Enlighten, SolarEdge Monitoring, whichever). This proves the system performs, not just that it exists.
Comparable Alberta sale. One same-neighbourhood solar home sale comp does more for the appraisal than three Toronto comps. Your realtor can pull these from MLS — ask specifically.
AHJ permit and electrical inspection. Your municipal electrical permit and Master Electrician's record-of-permit. This proves the system is code-compliant and won't trigger a buyer's home inspector to demand remediation.
The single biggest reason a real premium gets discounted to zero is paperwork that's missing or scattered. Have everything ready before listing.
Net metering, warranties, and the Solar Club account at sale
Net metering follows the address
Under the Alberta Micro-Generation Regulation (Alta Reg 27/2008), the bi-directional meter and the micro-generation classification are tied to the service address, not to the customer account. When the home transfers, the buyer opens a new electricity retail account at the address; the meter stays, the interconnection approval stays, and the micro-generation status transfers automatically. The seller doesn't need to do anything special — but providing the original micro-gen approval letter to the buyer's lawyer makes the closing smooth.
Solar Club enrolment is portable
If you were on a Solar Club retailer (Park Power, Bow Valley, Encor, ATCOenergy, Spot Power, etc.), the new homeowner can sign up directly with that retailer or any participating one. The HI/LO/Pre-Solar rate structure follows the address as long as the new account is opened with a participating retailer. Full retailer list.
Equipment warranties transfer with the title
LONGi Hi-MO 7 panels: 30-year product warranty + 30-year linear performance warranty (≥87% output at year 30), transferable to subsequent homeowners. APsystems DS3 microinverters: 25-year warranty, transferable. Roof Tech RT-MINI II mounts: lifetime structural, transferable. Stellar Upgrades' workmanship warranty: registered to the install address, transferable. The buyer inherits the full warranty stack at no cost — one of the strongest resale arguments you can hand to a hesitant buyer.
CEIP-financed systems
If your system was financed through the Clean Energy Improvement Program (CEIP — Beaumont, Spruce Grove, Edmonton, St. Albert), the remaining balance is attached to the property as a tax surcharge. At closing, you either (a) pay it out from the sale proceeds, or (b) leave it attached for the buyer to assume with the property. Most buyers will accept (b) at a marginally discounted purchase price, because the CEIP rate (3.5–6%) is typically below their mortgage rate. Disclose clearly on the Property Disclosure Statement.
10 things to do before you list (your seller's checklist)
- Pull your original installed cost invoice, including equipment serials and system size in kW.
- Pull your AHJ electrical permit and the inspection sign-off.
- Pull your micro-generation interconnection approval letter from your utility.
- Confirm warranty registrations are in your name (LONGi, APsystems, mounts, installer workmanship). If transferred, register with new owner's name at closing.
- Export the last 12 months of production data from your monitoring app as a PDF.
- Take 5–6 high-resolution photos: aerial of the array, close-up of a panel, the inverter cabinet, the bi-directional meter, the electrical service panel with the solar breaker labelled.
- Confirm your retailer of record. If Solar Club — great, name the retailer and rate plan on the disclosure. If not — flag that the buyer could enroll.
- If financed: check whether the loan is being paid out at closing or assumed; document this on the Property Disclosure Statement.
- If CEIP: confirm the remaining tax-attached balance with the municipality and disclose it.
- Hand your realtor a one-page "Solar Package" with all of the above. If you don't want to assemble it yourself and Stellar installed your system, call us — we'll do it free, even if we didn't install it.
What other Alberta sources say — and where they go wrong
The internet is full of Alberta solar home-value content that's well-meaning but inaccurate. Below is a calibrated comparison of common claims we see — from competitor installer marketing, generic Canadian solar blogs, and U.S.-imported content — against what's actually defensible for Alberta in 2026. We're not naming names; we're naming patterns.
| Common claim | What's actually true (Alberta 2026) |
|---|---|
| "Solar adds 4.1% to your home value — period." | The 4.1% is Zillow's mean across 1M+ U.S. sales. In Alberta, it varies from ~1.5% (small 3 kW on a $550K home) to ~7% (large 30 kW on the same home). Size matters. Property value matters. Ownership status matters more than either. |
| "Solar pays back in 5 years AND adds $40K to your home value — double win!" | Payback math and resale math overlap. The same energy savings that drive your payback ARE what the next buyer is paying for. You can't fully double-count them. Honest framing: solar is a 25-year asset; payback captures years 1–10, resale captures any unused value if you sell early. |
| "Free solar! $0 down! No catches!" | If you're not paying anything, you don't own the panels. The contract is almost always a 20–25 year lease or PPA. At resale, that contract becomes a liability that reduces sale price by ~1.5% of property value or kills the deal entirely. Real $0-down options that preserve ownership exist (Financeit 0%/12mo, CEIP, mortgage roll-in) — but they're loans, not gifts. |
| "Bigger system = bigger resale uplift, linearly." | No. Per-watt premium declines as system size grows (LBNL's documented finding, and the curve our calculator uses). A 20 kW system adds more total dollars than a 10 kW system, but not 2× as much. The right answer is to size to your actual annual consumption. |
| "Solar appraises automatically — the appraiser will figure it out." | Appraisers credit what they can document. If you don't hand them the install invoice, the micro-gen approval letter, the warranty registrations, the production data, and a comparable local solar sale — they often default to zero credit. Paperwork is the difference between full premium and no premium. |
| "Insurance premiums will spike — insurance companies hate solar." | TD Insurance, Intact, Aviva, Co-operators, and Wawanesa all insure solar in Alberta. Premiums rarely move materially — sometimes fall, because the roof improvements (RT-MINI II self-flashing mounts, new conduit) tighten the building envelope. See our hail and insurance guide for carrier-specific detail. |
| "Just use the LBNL $4/W number, multiply, done." | LBNL's $4 was USD, for 5 kW systems that cost $7–$8/W to install, transacted 2002–2013. Modern Alberta install is $2.80/W CAD. Naively converting gives wrong answers in both directions. Our curve recalibrates LBNL's recovery ratio (50–80% of install cost) to 2026 Alberta pricing. |

Five myths to stop believing
Myth: "Solar adds nothing because it's already old when I sell." Wrong. Even a 15-year-old LONGi system still has 15 years of linear performance warranty remaining and produces ~90% of rated output. The decay is gradual — the calculator above models this honestly.
Myth: "Buyers don't care about solar." The data disagrees. Zillow's 2019 1M+ sale analysis is the single biggest dataset and it found a 4.1% premium and faster sale times. In 2026, with Alberta retail rates climbing, that interest is rising, not falling.
Myth: "Solar will hurt my home's appraisal because of the roof penetrations." Wrong for code-compliant installs. We use Roof Tech RT-MINI II ICC-ESR-3575 self-flashing mounts — no pilot holes through the deck, 180 mph wind rating, 90 PSF snow rating — backed by Stellar's lifetime leak-proof roof guarantee on cash installs. A licensed home inspector will sign off cleanly. The mounts will outlast the roof.
Myth: "I'll move soon, so solar doesn't make sense." The owned-solar premium is captured at sale, not amortised over your stay. If you install today, sell in 3 years, and recover $20,000+ at sale on your $25,000 system — plus 3 years of bill savings — you're net-ahead. The "stay 15 years to break even" framing is a myth from the lease era.
Myth: "Solar makes my home harder to insure." Stellar's installs are reported to insurance carriers as a fixed improvement; we've worked with TD Insurance, Intact, Aviva, Co-operators, and Wawanesa on past customer policies. Premiums typically don't rise meaningfully (sometimes fall, due to roof improvements). See our hail and insurance guide for carrier-by-carrier coverage detail.
Special cases
Acreages, farms, and ground-mount systems
Ground-mount and acreage systems carry the same per-watt premium framework, but the buyer pool is smaller (rural buyers) and appraisers occasionally treat ground arrays as outbuildings rather than home improvements. Best practice: get an appraisal from someone with rural Alberta experience and provide a written rationale citing AIC guidance. The premium typically materialises — it just takes more documentation. We're working on a dedicated acreage solar guide for later in 2026.
Condos and townhouses
For townhouses with detached private roofs, the same rules apply, with the added requirement of getting your condo board's written approval before the install — and keeping a copy for the next buyer. For shared-roof condos, residential solar typically isn't feasible without board-level retrofit, which is outside the scope of this article.
Solar + battery + EV charger combos
A bundled solar + EP Cube battery + Wallbox EV charger system carries an above-average premium because it appeals to a growing buyer segment (EV owners). LBNL doesn't separately quantify the battery premium, but anecdotal Alberta market evidence suggests an additional 0.5–1.5% on top of the solar-alone premium.

Ready to run your actual numbers?
The calculator at the top of this post is a fair Alberta-adjusted model, but your real resale uplift depends on your specific neighbourhood comps, your system's documentation quality, and your remaining warranty stack. We do a free 15-minute assessment that reviews your existing solar paperwork (if you have any), pulls your last 12 months of utility consumption, and either gives you a resale-readiness one-pager or quotes a new install at a fixed price. We decline ~10% of new-install assessments when the math doesn't work — honest sizing is cheaper for everyone.
