Lakewood solar: decide the Solar Bank question before anyone measures your roof
Written by the Solar Learning Lab research deskUpdated August 30, 202612 min read
Buried in Xcel's Solar Rewards FAQ is a choice most Lakewood buyers hear about for the first time at signup, if at all. When your panels outproduce your house, the surplus has to go somewhere, and Xcel offers exactly two destinations. Take the default and the extra kWh sit in a Solar Bank until year end, when Xcel mails a check priced at its average hourly incremental cost of electricity, a wholesale derived number. Or elect Continuous Rollover, and the surplus becomes a dollar credit at the prevailing total energy rate that offsets everything on the bill except the Service and Facilities charge, rolling forward month after month.
Here is the part that deserves a full minute of silence: the rollover election is permanent. It never converts to cash. It does not follow you to a new address. The reverse switch, from rollover back to the annual check, is not allowed, and the only move you get is from the default into rollover, by December 1. That asymmetry is why this page opens with a compensation election instead of a sunshine statistic. Lakewood has plenty of sun. What it punishes is signing before thinking.
Sort the election, then size the array
A surplus heavy design and a consumption matched design point to different Solar Bank answers. Start with a screening estimate.
Estimate Lakewood solarWhich door fits which household
Work the logic, not the labels. The annual check path, which Xcel calls the Waive Decision, prices your surplus at AHIC, a rate derived from wholesale costs rather than the retail rate you pay. The research point worth repeating from the program FAQ: that payout sits far below retail, so a system built to overproduce on purpose is donating margin to the grid. Rollover keeps surplus value at the full energy rate, but only as bill credit, and only for as long as you live at that address.
So the honest sorting question is tenure. A household planning to stay put for a decade, with winter usage that can absorb summer credits, gets real value from rollover. A household that might sell in three years should think hard before making a permanent election whose balance evaporates at the closing table. And every household, either way, wins most by sizing the array so the bank stays small. Surplus is a rounding error to manage, not a revenue stream to chase.
One calendar note to write down: the December 1 deadline for switching from the default into rollover. Miss it and the decision waits another year, per the same FAQ.
What a Lakewood kilowatt hour is actually worth
Xcel has served this city a long time; the Partners in Energy work plan Lakewood signed with the utility notes a working relationship dating to 1969, per the city's own planning document. Across Xcel's Colorado residential base, power averaged 15.05 cents per kWh in 2024 in EIA's Table 6 data. The base Schedule R structure underneath that average, from the Colorado residential rates brochure, splits by season.
| Energy source | Type | Average price | What that means |
|---|---|---|---|
| Xcel Energy (PSCo) | Schedule R summer energy, base | 10.380¢ per kWh | Base rate in effect May 1, 2024, before riders and adjustments. |
| Xcel Energy (PSCo) | Schedule R winter energy, base | 8.570¢ per kWh | Service and Facility charge of $7.10 per month applies year round. |
| Xcel Energy (PSCo) | 2024 all-in residential average | 15.05¢ per kWh | EIA Table 6 across 1,365,053 Colorado residential customers, riders included. |
| Solar surplus | Rollover credit vs annual check | total energy rate / AHIC per kWh | Rollover credits at the prevailing total energy rate; the year end check pays a wholesale derived AHIC rate. |
Base rates from Xcel's CO residential rates brochure; average from EIA Table 6; surplus mechanics from the Solar Rewards FAQ.
The gap between the base energy rate and the 15 cent all-in average is riders and adjustments, and that gap is where solar earns quietly: a kWh you generate and consume on site avoids the whole stack, not just the base rate. A Production Meter Charge and Load Meter Charge of $2.55 each can apply to solar accounts, per the brochure, so ask any bidder to show those on the projected bill rather than discovering them later.
Two sizing gates stand between you and the interconnection
The rates brochure defines both. Schedule PV accepts parallel-operating photovoltaic systems from 500 watts up to 25 kilowatts, with anything larger needing case by case company approval. Schedule NM, the net metering schedule, caps retail renewable distributed generation at 200 percent of the customer's reasonably expected average total consumption, measured through a single bidirectional meter.
Read those two numbers together and the design brief writes itself. The hardware window is wide; the consumption cap is the binding constraint for most homes. An installer proposing a system near the 200 percent line should be able to explain, with your usage history on the table, why doubling your consumption is a plan and not a pitch. Given how the Solar Bank treats surplus, we would rather see Lakewood systems land under 100 percent of load than flirt with the ceiling.
File under Alternative Energy, and bring an engineer
Lakewood routes solar through its eTRAKiT portal under a permit type literally named Alternative Energy, per the city's solar installation guide. Homeowners need an eTRAKiT account; anyone hired for the work must hold City of Lakewood contractor registration, and separate registered contractors get added to the permit for electrical or plumbing scopes. The Permit Counter in Public Works answers at 303-987-7500, per the building permits page.
The technical bar is higher than neighboring suburbs advertise. A registered Colorado Professional Engineer must perform the structural analysis of the existing roof and the new installation, and electrical systems involving a service panel over 200 amps need a PE seal too. Plan sets must show 2021 International Fire Code areas of exclusion, roof covering materials and layers, roof and panel pitch, attachment details, and a PV one line diagram designed to the 2020 National Electrical Code. Ground mounts add a plot plan at 1 inch to 30 feet showing property lines and easements.
And one rule we have not seen written this bluntly elsewhere: structural connections must land directly on the roof framing through not more than one layer of asphalt shingles. If your roof carries two layers, that sentence just added a tearoff conversation to your solar project. Better to have it now than at inspection.
A valuation formula with a statutory lid on it
Lakewood publishes no flat solar fee. Permits price off project valuation using the January 2021 fee schedule: $77.75 for the first $2,000 of valuation plus $13.80 for each additional $1,000 up to $25,000, with estimated use tax of 3 percent of 50 percent of valuation collected on top. Run that on a typical solar contract and the total climbs fast enough to matter.
Which is where the state steps in. HB21-1284 caps aggregate government charges on a residential active solar installation at $500, and the cap now runs through December 31, 2029. So the formula sets the ask, the statute sets the maximum, and a Lakewood homeowner should verify the invoice respects the second. Worth knowing too: Lakewood has not adopted SolarAPP+ instant review; the platform's Colorado page lists Bennett, Wheat Ridge, Denver, Alamosa and Gilpin for full plan review, and Lakewood is not among them. Budget a conventional review timeline.
The sky here throws baseballs sometimes
The Front Range sits in what the Rocky Mountain Insurance Information Association calls Hail Alley, the highest large hail frequency in North America, and this is not an abstraction for Lakewood specifically: the May 2017 storm that caused over $2 billion in damage pounded parts of Golden and Lakewood with baseball sized hail, part of more than $5 billion in insured Colorado hail losses in a decade, per Denver7's storm retrospective.
What follows from that, practically: ask for the impact rating on the exact module being quoted, not the brand family. Ask your insurer how the array changes your deductible structure before installation, not after a storm. We will not quote you Lakewood specific claim counts because none were verifiable, and any installer who does is improvising. The one layer of shingles attachment rule from the permit section has a silver lining here, because a solid framing connection is exactly what you want when the weather turns violent.
Output at 5,656 feet, in the shadow of Green Mountain
Our downtown Lakewood run models 1,551.5 kWh per year per installed kW. June peaks at 147.7 kWh per kW, December bottoms at 99.1, and the March through September stretch never drops below 133. For a semi-arid city pressed against the foothills, that is a long, dependable plateau.
June models 147.7 kWh per kW, but the real story is the plateau: seven straight months above 133. Dry Front Range air keeps the curve flat.
PVGIS v5.2 model run by Solar Learning Lab on August 30, 2026, NSRDB radiation database. Fixed south facing mount, 30 degree tilt, 14 percent losses, downtown Lakewood coordinates. Your roof will differ. Tool documentation at PVGIS. Local geography adds nuance the model cannot see: Green Mountain, a 6,854 foot mesa in the far west central part of the city, shapes late afternoon shade for homes tucked against it, and July mean daily maximums of 85.9 F mean summer output arrives alongside real cooling load. Both are arguments for a site visit over a satellite quote.
The 2026 tax position, without the wishful thinking
Start with the subtraction: the federal 25D homeowner credit does not apply to expenditures made after December 31, 2025, and the IRS treats an expenditure as made when installation is completed, so a system finished in 2026 gets nothing, per the Congressional Research Service. Colorado offers no state income tax credit for panels either; we checked and found none on any fetched state page.
What survives is worth listing precisely. C.R.S. 39-26-724 exempts renewable generation components, modules, racks, inverters and wiring included, from state sales and use tax, though labor, storage devices and remote monitoring are excluded. The Division of Property Taxation confirms residential renewable equipment owned by the homeowner and serving the home is exempt from Colorado property tax. And the live deadline: the state's 10 percent residential energy storage credit under C.R.S. 39-22-546 runs through tax year 2026 and repeals January 1, 2027. If a battery is in your plans at all, this is the year the state pays you to decide.
HOA worried? C.R.S. 38-30-168 voids covenants that effectively prohibit renewable energy devices. Aesthetic conditions survive only if they raise cost by no more than 10 percent, cut performance by no more than 10 percent, and clear review within 60 days, after which the application is deemed approved. Print it, attach it, done.
The bench that shows up in Lakewood driveways
Our Lakewood pull surfaced five companies, mostly Denver based plus one in Golden, with review counts from 197 up to 644. Depth like that means you owe nobody a signature after one meeting. Collect three bids and make each one commit, on paper, to the Solar Bank election it assumes and the permit fee it expects after the HB21-1284 cap.

The Lakewood specific filter question: which permit type do you file in eTRAKiT, and who stamps the structural analysis? The right answers are Alternative Energy and a registered Colorado PE, without hesitation. A blank look on either is your exit.
Pressure test the numbers yourself
The estimator below runs the 2024 Xcel Colorado average rate against our Lakewood production model. It deliberately ignores the Solar Bank, because no calculator should hide a permanent election inside a slider. Use it to bracket system size and cost, then apply the rollover versus check logic from the top of this page to whatever surplus your bracket implies.
The slider tops out at our downtown Lakewood PVGIS figure, 1,551.5 kWh per kW per year. The floor trims 15 percent for shade and off south orientation. Front Range altitude keeps even the floor respectable.

Colorado has no state income tax credit for panels. The Lakewood cash case rests on quieter levers: no state sales tax on modules, racking, inverters and wiring, no property tax on qualifying residential systems, and a 10 percent state credit on a qualifying battery that ends with tax year 2026.

No Lakewood specific loan program was verified, so lenders compete on APR and dealer fee alone. HB21-1284 caps government solar permit charges at $500, which means soft costs on a quote deserve scrutiny, not sympathy.
